Rejuvenate Bio is Reversing Age-Related Diseases to Increase Healthspan – BioSpace
Posted: October 7, 2021 at 3:43 pm
Rejuvenate Bio Co-founder and CSONoah Davidsohn/Courtesy Rejuvenate Bio
The myth of a fountain of youth has inspired explorers for centuries, but modern scientists have come closer than any to understanding the secret of long, healthy lives. As it turns out, that secret is genetic.
Today, we think about aging as a dysregulation of genes and proteins that lead to age-related diseases, such as heart disease, obesity, diabetes, etc. When we talk about reversing aging or, more accurately, the disease states associated with aging were talking about reregulating genes back to the healthy state people had when they were younger, Noah Davidsohn, Ph.D., co-founder and CSO of Rejuvenate Bio, told BioSpace.
Unlike most companies addressing the diseases associated with aging, Rejuvenate Bio tackles multiple cardiac, metabolic and renal issues at once. Based on the data weve seen from mice and dogs, we can reverse obesity, diabetes and heart disease, Davidsohn said.
Rejuvenate Bio has two therapies in its pipeline, RJB -01 and RJB-02, targeting the cardiac, metabolic and renal space. Both are delivered via adeno-associated viruses (AAV).
Co-founder and CEO Daniel Oliver said he expects RJB-01 to enter the clinic for humans in 2023, and also to be commercialized for animals that same year. RJB-01 targets overexpression of FGF21 and downregulation of TGF1 via expression of sTGFR2. Rejuvenate is developing it for heart failure. Research conducted by other companies shows that targeting these genes is also effective and safe for weight loss, diabetes and tumor inhibition.
The second therapy, RJB-02, is designed to treat osteoarthritis. It targets two genes downregulation of TGF1 via expression of sTGFR2, and overexpression of Klotho. The latter is associated with improving cognitive performance as well as protecting the heart and kidneys, and increasing insulin sensitivity.
Davidsohn and Oliver proved the concept behind this gene therapy approach with colleagues at Harvard Medical School in 2019. A PNAS paper from the time detailed the results of modulating three genes associated with longevity fibroblast growth factor 21 (FGF21), Klotho, and a soluble form of mouse transforming growth factor- receptor 2 (sTGFR2) delivered via adeno-associated viruses. Notably, the researchers combined two therapies into one to treat four age-related conditions.
The results in mice showed a 58% increase in heart function in ascending aortic construction ensuing heart failure, a 38% reduction in -smooth muscle actin (SMA) expression, and a 75% reduction in renal medullary atrophy in mice subjected to unilateral ureteral obstruction, as well as a complete reversal of obesity and diabetes phenotypes in mice fed a constant high-fat diet, the paper noted.
Whats particularly exciting is that in mice, we showed we could halt progression of heart disease in its tracks despite the surgical tightening of the aorta, Davidsohn said. Similar results were seen in dogs, too.
Building on that early work, Rejuvenate Bio, which spun out of George Churchs lab at Harvard Medical School, has a study underway to treat mitral valve disease in dogs. After one and a half years, weve seen no safety problems, Oliver said, and preliminary data suggests this therapy has the ability to treat heart failure.
Rejuvenate Bio has a dual animal/human business strategy that enables it to capitalize on the many animal studies that are required as part of the U.S. Food and Drug Administration review process.
Its compelling that the same treatment goes into animals and humans, Oliver said. As we generate data in any of the areas, we lower the risks. Hopefully, this will allow us to go into a number of indications quickly and easily.
Since its inception in early 2018, Rejuvenate Bio has raised approximately $27 million in funding. Of that, $18.5 million is private and venture debt. Non-dilutive funding makes up the remainder. That lets us get to market in 2023 for animal health, and start human clinical trials, Oliver said.
Notably, its clinical work for canine and human trials is symbiotic. The targeted animal safety clinical trials that are needed before a product can be marketed for animal health also meet the requirements for the FDAs large animal pre-Investigational New Drug (IND) toxicology experiment. Those canine studies also enable accelerated aging studies. By evaluating tens of thousands of dogs with mitral valve disease, the research team can see the progression, halt or reversal of disease and the effects on the dogs quality of life in ways that are more robust than in an academic setting. Therefore, Oliver said, animal health is a huge component of this, and a huge unmet need (for canine health).
Then, the company needs to complete an additional pre-IND package for human trials. Weve connected with the regulators, so we have a well-defined path in terms of whats needed to get to human trials and to get through animal health trials, Oliver said. Now its just a question of executing on what we know we need to do.
Currently, Rejuvenate Bio is in the process of transferring manufacturing to a third party manufacturer and is working with leading animal health providers to ink a partnership.
At the same time, Oliver and Davidsohn are fine-tuning their human clinical development plan. We want to push past single monogenetic disorders. Were working with Kathy High, M.D., scientific advisory board member and former head of Spark Therapeutics, on clinical development paths to get to the clinic quickly, and to attack a disease with high unmet needs, but that also has potential for larger indications in the cardiac, metabolic or renal spaces, Oliver said.
The goal, Oliver and Davidsohnstressed, is to lengthen individuals healthspans the time they are healthy and vital. Thats a key ideological difference, Davidsohn pointed out. The point isnt to live longer in a state of poor health. We want all a persons years to have positive health. Therefore, increasing ones healthspan is very important, and its possible through aging reversal.

When it comes to books about the mind, the first ones I think of are Carol Dwecks Mindset: The New Psychology of Success and Daniel Kahnemans Thinking, Fast and Slow (the latter of which I will freely admit I have only read half of). I found both very interesting if also very different in their approaches to our minds. If I spend a little more time, I might think of a few more titles. However, the first ones that come up all reflect my own quirky interests. Those interests could be broadly labeled as education and self-improvement (of a particular bent, Ill admit).
Any list of books about the mind could naturally cover a range of subtopics. This one does so, but not nearly as broadly as it could. I think I have limited it naturally due to my own interests and so it breaks down into some categories I personally find more interesting than others. These are books about expanding your mind, books about understanding the mind, and books that will help you in training your mind to work better (depending on how you define better) for you. I have also tried very hard to include a variety of writing styles to interest different types of readers. So without much further ado, lets begin!
Gupta writes that his interest in this book is not about expanding ones intelligence per se, but rather in helping the reader cultivate new brain cells and learn to use them more efficiently. To this he adds a focus on resilience and how to encourage it in your own brain.
The book has three parts. The first covers the basics of what the brain is and does, and how to understand the aging brain. Part two may be more of what most readers would expect from a book like this: an overview of all the practical strategies that a person can use to keep the brain healthy, ending with a 12-week plan to put these science-based ideas into practice. Lastly, part three looks at the difficulties of identifying and treating brain diseases, and offers advice for those caring for loved ones whose brains are in decline. This is worth a read if you are looking for an accessible introduction to several areas of focus at once.

This book is about neurodiversity among those of us who identify as women and experience the world in different ways from what has been previously deemed normal. Nerenberg is a journalist who began a quest to understand this area after noticing her own difficulties processing certain types of input.
The book explores particular conditions that all have been labeled as sensitivities of one kind or another, like Attention deficit hyperactivity disorder, autism, and sensory processing disorders (among others) and how these neurodivergencies may present themselves in womens lives. While it can feel a bit tougher to follow at times in her book, Nerenberg makes an important effort here to expand existing understandings of neurodiversity to encompass more experiences of women.
Those are my titles for books about the mind. However, an obvious angle I am missing here is what happens to our brains when we read? If youre wondering too, you can start with this post about books on the reading brain and keep going with this one on the neuroscience of audiobooks. And as always, enjoy your mind and its endlessly wonderful ability to turn random-seeming markings into meaning!

These 125 million-year-old fossils may hold dinosaur DNA – Livescience.com
Posted: at 3:39 pm
The remnants of DNA may lurk in 125 million-year-old dinosaur fossils found in China. If the microscopic structures are indeed DNA, they would be the oldest recorded preservation of chromosome material in a vertebrate fossil.
DNA is coiled inside chromosomes within a cell's nucleus. Researchers have reported possible cell nucleus structures in fossils of plants and algae dating back millions of years. Scientists have even suggested that a set of microfossils from 540 million years ago might hold preserved nuclei.
These claims are often controversial, because it can be hard to distinguish a fossilized nucleus from a random blob of mineralization created during the fossilization process. In the new study, published Sept. 24 in the journal Communications Biology, researchers compared fossilized cartilage from the feathered, peacock-size dinosaur Caudipteryx with cells from modern chickens; they found structures in the fossils that looked much like chromatin, or threads of DNA and protein.
"The fact that they are seeing this is really interesting, and it suggests we need to do more research as to what happens to DNA and chromosomes after cell death," said Emily Carlisle, a doctoral student who studies microscopic fossils and their preservation at the University of Bristol in England but was not involved in the new research.
To answer the obvious burning question: No, we're nowhere close to resurrecting dinosaurs from their fossilized DNA.
"If there is any DNA or DNA-like molecule in there, it will be as a scientific guess very, very chemically modified and altered," Alida Bailleul, a paleobiologist at the Chinese Academy of Sciences who led the new research, wrote in an email to Live Science.
Related: Is it possible to clone a dinosaur?
However, Bailleul said, if paleontologists can identify chromosome material in fossils, they may someday be able to unravel snippets of a genetic sequence. This could reveal a little more about dinosaur physiology.
But first, researchers have to find out if the DNA is even there. Until recently, most paleontologists thought that rot and decay destroyed the contents of cells before fossilization could take hold. Any microscopic structures inside cells were considered collapsed cell contents, such as organelles and membranes, that had rotted before mineralization, Carlisle told Live Science. More recently, though, paleontologists have found legitimate cell structures in a few fossils. For example, 190 million-year-old fern cells described in 2014 in the journal Science were buried in volcanic ash and fossilized so quickly that some were frozen in the process of cell division. Unmistakable chromosomes are visible in some of these cells.
In 2020, Bailleul and her colleagues reported the possible preservation of DNA in the skull of an infant Hypacrosaurus, a kind of duck-billed dinosaur that lived 75 million years ago, found in Montana. The possible DNA was found in cartilage, the connective tissue that makes up the joints.
"We were specifically interested in the cartilage because it's a very good tissue for cellular preservation, perhaps even more so than bone," Bailleul said.
For the new study, the researchers turned to a well-preserved specimen of Caudipteryx held by the Shandong Tianyu Museum of Nature in China. Originally discovered in the northeastern province of Liaoning, the fossil has ample preserved cartilage, which the researchers stained with the same dyes used to image DNA in modern tissue. These dyes bind to DNA and turn it a specific color, depending on the dye, allowing the DNA to stand out against the rest of the nucleus. By examining the stained, fossilized cartilage with several microscopy methods, Bailleul and her team showed that the cartilage cells contain structures that look just like nuclei with a scramble of chromatin inside.
Related: Photos: Fossilized dinosaur embryo discovered
The stained dinosaur nuclei's resemblance to modern cells doesn't prove there is DNA inside them, though, Bailleul cautioned. "What it means is that there are definitely parts of original organic molecules, perhaps some original DNA in there, but we don't know that yet for sure," she said. "We just need to go figure out exactly what these organic molecules are."
The imaging definitely seems to show nuclei, Carlisle said, but it's harder to identify fossilized chromosomes, because no one really knows what happens to chromosomes as they decay. It's possible that the contents of the nucleus might just collapse into structures that look like chromosomes but are really just a jumble of meaningless mineralized junk; it's also possible that the fossilization process preserves some of the original molecular structure. (One 2012 study suggests that DNA in bone will completely break down in about 7 million years, but the timing may depend heavily on environmental factors.)
"It would be really interesting to do more experiments into that, looking at what happens inside the nuclei instead of just what happens to it from the surface," Carlisle said.
Bailleul and her colleagues hope to collect more chemical data to nail down the identity of the mysterious structures.
"I hope we can reconstruct a sequence, someday, somehow," she said. "Let's see: I could be wrong, but I could also be right."

Enzymatic Synthesis: Our DNA Is Becoming the Worlds Tiniest Hard Drive – SciTechDaily
Posted: at 3:39 pm
Researchers propose faster method for recording data to DNA, showing promise in fields of digital data storage, neuron recording.
Our genetic code is millions of times more efficient at storing data than existing solutions, which are costly and use immense amounts of energy and space. In fact, we could get rid of hard drives and store all the digital data on the planet within a couple hundred pounds of DNA.
Using DNA as a high-density data storage medium holds the potential to forge breakthroughs in biosensing and biorecording technology and next-generation digital storage, but researchers havent been able to overcome inefficiencies that would allow the technology to scale.
Nature is good at copying DNA, but we really wanted to be able to write DNA from scratch. Keith Tyo, Associate Professor of Chemical and Biological Engineering
Now, researchers at Northwestern University propose a new method for recording information to DNA that takes minutes, rather than hours or days, to complete. The team used a novel enzymatic system to synthesize DNA that records rapidly changing environmental signals directly into DNA sequences, a method the papers senior author said could change the way scientists study and record neurons inside the brain.
The research, Recording Temporal Signals with Minutes Resolution Using Enzymatic DNA Synthesis, was published on September 30, 2021, in the Journal of the American Chemical Society. The papers senior author, Northwestern Engineerings Keith E.J. Tyo, said his lab was interested in leveraging DNAs natural abilities to create a new solution for storing data.
The papers senior author, Northwestern engineering professor Keith E.J. Tyo, said his lab was interested in leveraging DNAs natural abilities to create a new solution for storing data.
Nature is good at copying DNA, but we really wanted to be able to write DNA from scratch, Tyo said. The ex vivo (outside the body) way to do this involves a slow, chemical synthesis. Our method is much cheaper to write information because the enzyme that synthesizes the DNA can be directly manipulated. State-of-the-art intracellular recordings are even slower because they require the mechanical steps of protein expression in response to signals, as opposed to our enzymes which are all expressed ahead of time and can continuously store information.
Tyo, a professor in chemical and biological engineering in the McCormick School of Engineering, is a member of the Center for Synthetic Biology, and studies microbes and their mechanisms for sensing environmental changes and responding to them quickly.
Existing methods to record intracellular molecular and digital data to DNA rely on multipart processes that add new data to existing sequences of DNA. To produce an accurate recording, researchers must stimulate and repress expression of specific proteins, which can take over 10 hours to complete.
The Tyo lab hypothesized they could use a new method that they called Time-sensitive Untemplated Recording using Tdt for Local Environmental Signals, or TURTLES, to synthesize completely new DNA instead of copying a template of it, making a faster and higher resolution recording.
As the DNA polymerase continues to add bases, data is recorded into the genetic code on a scale of minutes as changes in the environment impact the composition of the DNA it synthesizes. The environmental changes, such as changes in the concentration of metals, are recorded by the polymerase, acting as a molecular ticker tape and indicating to scientists the time of an environmental change. Using biosensors to record changes into DNA represents a major step in proving TURTLES viability for use inside cells, and could give researchers the ability to use recorded DNA to learn about how neurons communicate with each other.
This is a really exciting proof of concept for methods that could one day lets us study the interactions between millions of cells simultaneously, said Namita Bhan, co-first author and a postdoctoral researcher in the Tyo lab. I dont think theres any previously reported direct enzyme modulation recording system.
With more potential for scalability and accuracy, TURTLES could offer the basis for tools that catapult brain research forward. According to Alec Callisto, also a co-first author and graduate student in the Tyo lab, researchers can only study a tiny fraction of a brains neurons with todays technology, and even then, there are limits on what they know they do. By placing recorders inside all the cells in the brain, scientists could map responses to stimuli with single-cell resolution across many (million) neurons.
If you look at how current technology scales over time, it could be decades before we can even record an entire cockroach brain simultaneously with existing technologies let alone the tens of billions of neurons in human brains, Callisto said. So thats something wed really like to accelerate.
Outside the body, the TURTLES system also could be used for a variety of solutions to address the explosive growth in data storage needs (up to 175 zettabytes by 2025).
Its particularly good for long term archival data applications such as storing closed-circuit security footage, which the team refers to as data that you write once and read never, but need to have accessible in the event an incident occurs. With technology developed by engineers, hard drives and disk drives that hold years of beloved camera memories also could be replaced by bits of DNA.
Outside of storage, the ticker tape function could be used as a biosensor to monitor environmental contaminants, like the heavy metal concentration in drinking water.
While the lab focuses on moving beyond a proof of concept in both digital and cellular recording, the team expressed hope that more engineers would take interest in the concept and be able to use it to record signals important to their research.
Were still building out the genomic infrastructure and cellular techniques we need for robust intracellular recording, Tyo said. This is a step along the way to getting to our long-term goal.

How This Founder Is Leading The Way In Feline DNA Testing To Improve Lives Of Cats Around The World – Forbes
Posted: at 3:39 pm
Anna Skaya, founder and CEO of Basepaws, is pioneering the feline DNA at-home kits to provide cat ... [+] owners data on making their cats lives better.
Theres one thing pet lovers all have in common: they want the absolute best for their four-legged friends. In March, theAmerican Pet Products Associationannounced the industry reached over $100 billion in annual sales, the highest level in industry history. Thirty-four billion was spent on vet care and product sales, a 7.2% increase. According toSpots, 67% of American homes include a pet, with 53% owning dogs and only 35% owning cats. With more households owning dogs, there are more products on the market to test a canines DNA than feline DNA kits. On Chewys website alone, its a 10-to-3 ratio. However, as technology advances and interest increases, companies such as Basepaws make DNA kits for cats more accessible and accurate.
Anna Skaya, CEO and founder of Basepaws, is pioneering feline genetics while helping cat lovers better care for their pets by providing breed, DNA and dental health reports. With an ever-growing genomic database, she and her team are on a mission to improve the lives of cats around the world by understanding, genetically, what makes each cat unique.
Regarding the number of sequenced genomes from canine versus feline, the goals and available research funding for the two fields look completely different. For example, the99 Lives projecthas approximately 200 domestic cat genomes sequenced, compared to theDog10K project, which aims to sequence the genomes of 10,000 dogs and wild canids and all known dog breeds. At Basepaws, it is correcting this imbalance between the two fields. It is building the worlds largest feline genomics database, currently containing tens of thousands of feline genomes sequenced at either high or low depth.
The idea of genetics really spoke to me, Skaya stated. It was based out of a need that I had from my own cat, an interest that I found absolutely fascinating. ... I got a chance meeting with the CEO of 23andMe. She had just invested in a similar company to Basepaws but for dogs. She was very passionate about consumer genomics for humans and animals. And her passion rubbed off. I watched her speak to our group and it just clicked. I had a cat. I really was passionate about the idea of doing something in science. Im not a scientist, and I had to find a cofounder. I heard her say someone should do this for cats and call it 23andMeow. We all laughed. I went home that night and bought the URL. That was the beginning.
Skayas startup career began at Bazaarvoice. She started at the bottom and worked her way up. Eventually, the leadership extended her an opportunity to build out Bazaarvoice U.K. Once the office was up and running, she decided to go back to school to earn an M.B.A.

While presenting at her last conference on behalf of Bazaarvoice, an investor approached her, asking if she would be interested in a position on a four-person team to build out the idea of City Deal. She put her masters on hold, and within a week, she met the others on the team. In 18-months, Groupon started the process to acquire the company. She then became CEO of Russia Groupon.
I arrived there at twenty-seven, Skaya explains. There was a 200 person team, and the mandate was to get to 600 by the end of the year. We were halfway through the year. Im the CEO, and Im totally freaked out. I go from running a part of City Deal in the U.K. to running the whole thing in Russia. ... My experience with that company really toughened me up. I got there and lots of big burly men were raising their eyebrows. I had a lot to prove. I exited when the company went public.
Skaya then went on to launch two more companies, VisualDNA and breakupbuddy. My claim to fame is that I can sell things online, she smiles. I can get people to look at ads. ... By the time I was done with breakupbuddy, I was done with advertising. I was tired of chasing you around the web trying to sell you things. You could say that I had a little bit of an identity crisis of whether or not it was all worth it. I wanted to do something that was meaningful.
She was accepted into Silicon Valleys Singularity University, now Singularity Group. At that time, the program was backed by Google and based at NASAs Research facility in Mountain View. It focused on the challenges and opportunities presented by exponential technologies like robotics, artificial intelligence and genetic sequencing. During the year-long program, she built out
Without having any revenue, Skaya was able to raise $300,000 in pre-seed funding. Shes been on Shark Tank and has even faced investors telling her they didnt want to invest because they were dog people. She and her team are now about to close out a Series A round in the upcoming months.

Had this been a dog company, anything dog, I think it would have been much easier, she comments. Investors that I think would have been absolutely perfect for us did not identify with the problem that we were solving. I remember a very famous investor flew him and half of his team to Los Angeles to meet with us. A perfect fit on every level. Everything was great. It came down to him not being a cat person. ... I have it in writing, Im not a cat person.
As Skaya continues to transition and expand Basepaws, she focuses on the following essential steps:
Skaya concludes, Helping others and seeing them grow is such a great feeling.

DNA Allows the Reconstruction of Ancient Egyptian Mummy Faces – My Modern Met

Twenty-first-century advances in DNA technology have revolutionized the way we solve crimes and identify deceased Does. In September 2021, Parabon NanoLabsa DNA technology companyextended their expertise to the ancient mummies of Egypt. The DNA experts have recreated the hyperrealistic faces of three ancient Egyptian men using the same techniques currently used in creating sketches of crime victims.
Sometimes ancient history can seem remote and hard to imagine; however, seeing the faces of historical figures can help bring the past to life. The Parabon team used a technique called DNA phenotyping, which uses genetic markers to predict features such as hair color, skin tone, and eye color. They used this technique on the DNA sequence of three mummies from Abusir el-Meleq, an ancient Egyptian city. The men died between 1380 BCE and 450 CE. Their DNA was originally sequenced for a study in 2017. The study concluded from a set of 90 mummy profiles that ancient Egyptians are more closely related genetically to modern Near Eastern peoples.
While phenotyping is important to modern criminal and missing person investigations, it is particularly difficult when DNA is degraded or contaminated by bacterial material. Both of these problems occur frequently with ancient DNA, such as that of mummies. Phenotyping cannot produce a perfect image even with a full profile, and certain guesswork is necessaryparticularly in ancient cases. Parabon's Snapshot DNA Phenotyping pipeline tool attempts to fill in the gaps by using nearby markers. Dr. Ellen Greytak, Parabon's Director of Bioinformatics, said in a statement, [T]hese techniques are revolutionizing ancient DNA analysis because they operate on fragmented DNA and have been shown to be sensitive down to only 10 picograms of DNA.
Based on the DNA markers the researchers could discern, it was predicted the men shared brown hair, brown eyes, and light brown skin. Using the remains themselves, the team created heat maps of the facial features and their measurements for each individual. Forensic artists then created 3D sketches of the men based on the heat maps and DNA predictions. The result are stunning portraits which appear almost alive despite the hundreds of years of intervening history.
While modern technology has brought us these depictions, the ancient Egyptians themselves left behind very realistic depictions of the dearly departed. Particularly in the Roman period, Egyptians were often buried with painted mummy boards featuring portraits of the deceased. A particularly famous cache of such portraits are known as the Fayum Portraits. They have been called the oldest modernist paintings. As with the Parabon reconstructions, one could recognize these ancient individuals on the street. Whether audiences peer at the modern analysis or the ancient renderings, these images bring history to life.

Oxford Journal: Days of ‘Junk DNA’ Are Over – Discovery Institute
Posted: at 3:39 pm
Photo credit: xaviercanserra, via Pixabay.
Thanks to a friend for passing along a new article at the Oxford University Press journalGenome Biology & Evolution(GBE), by several authors (from German and French universities), which opened its discussion section with the sentence The days of junk DNA are over.
That by itself would be significant. Equally noteworthy, however, is the fact that GBE social media editor Casey McGrath an evolutionary biologist employed by the Society for Molecular Biology and Evolution (SMBE), the academic sponsor of GBE and its sister journalMolecular Biology and Evolution wrote a Highlight article calling attention to the observation that Junk DNA is No More. McGraths article, Junk DNA No More: Repetitive Elements as Vital Sources of Flatworm Variation, is open access.
None of this is accidental. Since project ENCODE provoked outrage among evolutionary biologists such as Dan Graur over a decade ago, there has been a concerted campaign to defend the notion of junk DNA, often explicitly in the context of anti-intelligent design sentiments. Graur, at the University of Houston, famously argued in 2013, in a major speech in Chicago to the SMBE, that if ENCODE is right, then evolution is wrong.
Younger evolutionary biologists such as Casey McGrath are watching all this. We should not assume McGrath has any ID sympathies; almost certainly, she does not. But questions about the possible functional roles of apparent junk DNA are just too interesting to allow oneself to be intimidated into silence by academic bullies such as Graur.

How a DNA test led a Chicago woman to find family ties to Mrs OLeary of the Great Fire fame – IrishCentral
Posted: at 3:39 pm
A DNA test kit revealed to a Chicago woman that she is a distant relative of Catherine O'Leary, an Irishwoman who was blamed for starting the Great Chicago Fire.
According to the Chicago Tribune, results from a DNA test done by Chicago local Cindy OGara, have shown that her biological father was the great-grandson of Catherine OLearys eldest child, Mary OLeary Scully.
O'Gara eventually connected with her birth fathers two sisters, who recalled family stories theyd grown up with and the 150-year-old tale that has haunted several generations of the OLearys, making their name synonymous with the citys destruction.
Their family story goes back to the 1800s when Patrick OLeary from County Kerry, Ireland married Catherine Donegan from County Cork.
After the birth of their first child, the family immigrated to America and Patrick enlisted in the Civil War. Soon after the war ended, the OLearys arrived in Chicago, where the couples last three children were born.
There are several versions of the legend of the Great Fire, but the most common one is that on October 8, 1871, Catherine OLeary went into a barn on a dry night with a lantern to milk one of her cows for oyster stew. OLeary left the lantern in the barn and the cow kicked it over and started the fire.
Chicago at that time was still a new city. Founded a mere 30 years before it was believed to be the fastest-growing city in the entire world. Most of it had been constructed in haste - and poorly at that - almost everything was made of wood and tightly packed together. Tragically the aftermath of the two-day blaze left 300 dead and 100,000 homeless.
The O'Leary family of the time long maintained that they were in bed that evening when the fire started. The cause of the fire still remains a mystery, with many agreeing now that a poor Irish emigrant was the perfect scapegoat. Catherine O'Leary was vilified for the rest of her life and would eventually die "heartbroken".

The fire remained a taboo subject within the O'Leary family for generations and the shame of the incident was passed down.
People would come from all over to throw rocks at the house, explained Peggy Knight, a great-great-granddaughter of Catherine and Patrick OLeary.
Now approaching the anniversary year of the familys biggest tragedy, descendants say theyre embracing their Irish heritage and want to finally put an end to the old rumor.
"Kate and Patrick OLeary were these strong people. Its hard to get out of Ireland during the Potato Famine, and then the shame heaped upon us, Knight said
I think its time for closure...I wish she would have [spoken to reporters], but there was no option. There was no social media. All that was written [on the incident] is what was written in the newspapers and it wasnt the gospel truth.
Reflecting on the discovery of her family and her connection to the O'Leary name, Cindy O'Gara said,
Obviously growing up in Chicago, I was very familiar with the story, but I always kept a distance from it, she said. But not now, because now I know. Its my blood. I know who I am now. Im an OLeary.
