A look at one of our most prominent genetics journals (Clinical Epigenetics) and its new companion publication (Epigenetics Communications), that both present the best in epigenetic research. Both titles are helmed by Professor Lucia Altucci and Professor Marianne Rots.

Vanessa Tse 23 Apr 2021

DNA Day, on the 25th of April every year, is meant to commemorate the discovery of the structure of DNA in 1953 by Watson and Crick and the successful completion of the Human Genome Project 50 years later. With this 68th DNA anniversary, we here highlight a topic that is closely associated with DNA: epigenetics.

The concepts of chemical modifications of histones associated with gene expression status were established after identification of the first mark histone acetylation began in 1964. The discovery of genomic imprinting in the mid-1980s led to the identification of DNA methylation, which soon became a well-established mechanism of epigenetic gene regulation. Together with histone acetylation, these epigenetic mechanisms were shown to play an important role in normal development of cells. It also explained the phenotype differences between individuals, for example, why identical twins might suffer from different diseases despite having identical genetic information. All these discoveries moved the field of Epigenetics forward.

Over the past years, with the rapid development of (epi)genome-wide technologies, there is a growing interest in epigenetics and its associations with a wide range of diseases. Epigenetics now is a fully independent research field next to genetics, providing biomarkers and new therapies.

The journal Clinical Epigenetics, founded by Dr Mahlknecht in 2009, covers all aspects of epigenetic (mis)regulation from before birth and early development, via healthy ageing and the influence of lifestyle and ageing on chromatin functioning, to clinical aspects including epigenetic biomarkers and epi-drugs. The expanding study of Epigenetics is revealing a significant impact on various disciplines with the journal currently well-positioned amongst other Genetics & Heredity titles.

The sister journal, Epigenetics Communications (EPIC) was recently launched by the Editors-in-Chief of Clinical Epigenetics (Drs Altucci and Rots) as an innovative, open-access journal devoted to the study of epigenetic principles and mechanisms in more basic research settings. The journal also provides a forum for null hypothesis-confirming results and therefore welcomes submissions of negative results systematic studies. It is supported by a strong and international editorial board. We are very excited to have our EPIC editors share their perspectives towards this rapidly growing field in a Meet the Editors interview series, which will be launched soon.

On this special day, we look forward to seeing more exciting advances in this important field as we work together in enriching it by providing platforms to exchange the latest research.

Sunday 25 April is DNA Day, which celebrates the discovery of DNA and the scientific advances made possible by uncovering this building block of life.

DNA Day celebrates two dates that are so important in cancer research the discovery of the double-helix structure of DNA by scientists including Francis Crick, James Watson, Maurice Wilkins and Rosalind Franklin, which was published in the journal Nature on 25 April 1953, and the completion of the Human Genome Project in April 2003, after 13 years of research. This was the first time scientists had read the complete sequence of human DNA, paving the way for new discoveries about human biology.

Without understanding DNA, understanding cancer and developing new treatments for the disease would be nearly impossible. Genetics plays a huge role in treating cancer, and its crucial for the care of many patients with cancer to understand the genetics of their disease.

Cancer is ultimately a disease of DNA. Our cells are constantly exposed to factors that can damage DNA, but they have a remarkable ability to repair mistakes when they occur even putting cell division on hold until repairs are complete.

Cells use a complex network of signals called the DNA damage response to control the process of detecting and repairing damaged DNA. But as cancer develops, this response can become defective making cells genetically unstable and causing them to accumulate more and more cancerous mutations.

Although defects in the DNA damage response can help cancers develop, they are also key genetic weaknesses that could be exploited to treat the disease.

Professor Jessica Downs, Professor of Epigenetics and Genome Stability at the ICR, is one of a group of researchers who are investigating how the DNA damage response works in healthy cells and how it can become defective in cancer.

Cancer cells with defects in their DNA damage response become more reliant on other systems to repair their DNA. So they could be susceptible to drugs that block these systems. Understanding how cancer becomes reliant on these repair systems could also help researchers identify new vulnerabilities in cancer that could be targeted with new treatments.

Researchers at the ICR famously applied this principle, known as synthetic lethality, in the development of drugs called PARP inhibitors, which are now used as a treatment for cancers with mutations to the BRCA genes.

Now Professor Downs and her team are studying a substance in cells called chromatin a mixture of DNA and proteins that helps package DNA to prevent damage. She is interested in how the proteins within chromatin help to support DNA damage repair in healthy cells and what happens to chromatin during the development of cancer.

Her lab is studying a particular protein complex within chromatin called SWI/SNF. This complex plays a role in winding or unwinding DNA so it can be copied or repaired, which can go wrong in cancer.

Professor Downs explains: The winding and unwinding of DNA is a tightly regulated process in cells, and the proteins controlling it play an important role in preventing and repairing wear and tear to DNA. The SWI/SNF protein complex helps maintain DNA in cells but its inactivated in roughly 20 per cent of cancers. Our lab is trying to understand why this protein complex is so important in the DNA damage response network, and what goes wrong in cancer.

By studying the role SWI/SNF plays in our cells, Professor Downs and her team have started to identify potential weaknesses that might be targeted by new drugs.

She is now working with colleagues in our Cancer Therapeutics Unit to develop compounds to target these proteins to treat cancer.

Our world-leading cancer research relies on the generosity and dedication of the thousands of individuals, organisations and companies that support our work.Help us today so that we can keep learning more about DNA damage and cancer.

As well as designing drugs to target DNA repair mechanisms, researchers at the ICR are also interested in ways of triggering more DNA damage to kill cancer cells.

Radiotherapy and some chemotherapies work by causing so much genetic damage that cancer cells cannot survive, but cancers can become resistant to these treatments by finding ways of repairing their DNA.

Professor Downs is working with Dr Navita Somaiah, a clinician scientist at the ICR and an expert in radiotherapy, to understand how cells respond to DNA damage caused by radiotherapy.

They are investigating how radiation-induced damage is repaired in different genetic contexts. It is possible that drugs that block the DNA damage response could make cancer cells more sensitive to radiotherapy, by stopping them from repairing the damage it causes. That could in turn improve outcomes for patients.

Dr Somaiah says: Targeting the DNA damage response could re-sensitise cancer that has become resistant to radiotherapy, which would be of great benefit to patients.

By understanding and exploiting cancers dependency on DNA damage repair, our researchers are using their knowledge of DNA to turn a strength of cancer into a weakness, which could open up new avenues of treatment and give hope to many patients with the disease.

Testing conducted by local conservation organization MountainTrue identified cattle and faulty or inadequate sewer, septic or water treatment infrastructure as the major sources of E. coli pollution in the French Broad River.

MountainTrues French Broad Riverkeeper conducts regular water quality monitoring of rivers and streams throughout the French Broad River Basin, including weekly testing of more than 30 recreation areas from May to September. After decades of slow but consistent improvement to the basins water quality, the organization has documented a sharp decline in water quality.

The difference over that past few years has been disturbing, explains French Broad Riverkeeper Hartwell Carson. Take Pearson Bridge in Ashevilles River Arts District: That site passed the EPAs safe threshold for swimming 81% of the time in 2016. Just four years later, that site failed 81% of the time in 2020. Or Mud Creek in Henderson County; that site passed 52% of the time in 2018, and now it fails 93% of our tests.

MountainTrues standard E. coli testing program measures the E. coli in the river. Levels in the French Broad have been high and rising year-over-year, but the nonprofit couldnt say for certain what the sources of the pollution were. Determining the major sources of E. coli required more expensive testing to look at the presence of DNA in the river.

The nonprofit says it approached Sen. Chuck Edwards, whose district includes Henderson and parts of Buncombe County, for help securing state funding to pay for sampling and lab costs. With that funding, MountainTrue looked at the DNA found in 55 water samples to look for genetic fingerprints of E. coli from people, cows, dogs, poultry, sheep and swine.

Of the 55 samples, 44 revealed DNA from cows. Human DNA was the second-most prevalent. The results vary, but at nearly every site the primary sources of pollution were cattle followed by human. Dog DNA also showed up as a moderate contributor to E. coli pollution at a few sample sites.

The French Broad has some clean and clear streams that run through protected public lands, but were seeing more and more problem sites that consistently fail the EPAs safe water standard for E. coli, says Carson. Until now, weve only had educated guesses about where the E. coli was coming from. With this testing, we have the data we need to make more informed decisions about how to clean up our rivers.

MountainTrue encourages the public to advocate for the adoption of a clean rivers policy agenda that includes funding to help farmers, property owners and local governments reduce water pollution.

The public can read about issues affecting water quality, and the policies and reforms MountainTrue says are needed to fix them at iloverivers.org.

Green in brief: DNA testing reveals sources of water pollution - Mountain Xpress

For decades popular culture has portrayed babies born to the survivors of nuclear accidents as mutants with additional heads or at high risk of cancers. But now a study of children whose parents were exposed to radiation from the Chernobyl disaster in 1986 suggests they carry no more DNA mutations than children born to any other parents.

The study, published in Science, is one of the first to systematically evaluate alterations in human mutation rates in response to a manmade disaster, such as accidental radiation exposure.

As well as providing fresh insights into how radiation affects the human body, the findings should help reassure other people who may have been exposed to radiation, such as those living near the Fukushima Daiichi plant in Japan in 2011, that it is safe to return home or have children.

Theres a lot of reticence among people to go back, and one of the major concerns is the transgenerational effects, said Dr Stephen Chanock, of the National Cancer Institute in Rockville, Maryland, who supervised the research. Theres this science-fiction societal view of three-headed babies, which is really accentuated in the Fukushima setting right now.

Although ionising radiation can damage DNA in the cells of people exposed to it, potentially their risk of cancer, it was less clear whether egg and sperm cells were similarly affected. In theory, mutations in these cells could be transmitted down the generations, potentially triggering developmental disorders or cancers in the descendents of radiation-exposed individuals.

To investigate this possibility, Chanock and his colleagues analysed the genomes of 130 children born to parents who were either involved in the cleanup of the Chernobyl site after the accident, or were evacuated from nearby towns and settlements, as well the parents genomes. All of the children were conceived after the accident.

Even though their parents had been exposed to high levels of radiation, there was no increase in the number of new mutations those not detected in either parent but that could have arisen because of damage to their eggs or sperm in these children.

These mutations may be in the parents blood, but were not seeing this horrific science-fiction-like mutation of sperm and eggs, said Chanock. I think this should be reassuring data that theres a lack of evidence for substantial or significant transgenerational effects.

Dr Alex Cagan, a postdoctoral fellow at the Wellcome Sanger Institute in Hinxton, England, said: While these findings do not diminish the innumerable personal tragedies associated with the Chernobyl nuclear accident they do provide a glimmer of hope that the potentially damaging effects to DNA do not appear to have been passed down to the children of those involved.

SAN DIEGO, April 22, 2021 (GLOBE NEWSWIRE) -- Bionano Genomics, Inc. (Nasdaq: BNGO), announced today the publication of a study that analyzed the mechanisms of DNA replication, a fundamental process of cell growth implicated in cancer that was previously hard to study in human genomes. The study, led by Dr. Nicholas Rhind from the University of Massachusetts Medical School with an international team of scientists from France, Canada and the USA, described a method combining optical genome mapping (OGM) with Bionanos Saphyr system with a labeling method developed by the scientists. The Saphyr-based method was capable of determining the timing, speed and origin of DNA replication in human cells at a coverage level that is thousands of times higher than what earlier methods such as nanopore sequencing allowed. The breakthrough quality and quantity of single molecule data generated by Saphyr in this study illustrates the importance of novel technologies such as OGM in driving a wave of big biology and innovation in genomics.

The body of humans and other organisms develop and grow when cells divide, and for each division the entire genome needs to be replicated. Mistakes in DNA replication can lead to genome instability and mutations that drive cancer. Because cancer cells divide excessively, many chemotherapeutic drugs target and disrupt DNA replication. A better understanding of these mechanisms could help develop new cancer drugs with reduced side effects.

The study of DNA replication in human cells has been difficult because existing technologies dont allow for a thorough investigation of this extremely complex process in human cells. For that reason, replication studies using single molecule technologies such as nanopore sequencing have typically been limited to yeast cells because the sequencing throughput does not allow the genomewide analysis of human cells. The largest replication study to date analyzed no more than the equivalent of a single fiber for each part of the human genome. In this study, the optical replication mapping with Saphyr was able to collect more than 2,500 fibers for each part of the genome, or 27 million fibers total with an average length thats 10 times larger than previous studies using long-read sequencing. The authors stated that the Saphyr-based method can become a central technique for studying DNA replication, DNA repair and genome instability.

Erik Holmlin, PhD, CEO of Bionano Genomics commented: At Bionano we are focused on driving what we believe will be next wave of big biology and innovation in genomics by unlocking access to genome structure, structural variation, and functional information derived from high volume single molecule analysis. For all the transformative technology thats available to researchers and clinicians today, none of them handles genomic structure, location and organization very well.This limitation leaves a gap in the basic understanding of genome function and the search for new medicines and diagnostic tests while other areas of genome analysis are being transformed by new technology. The optical replication mapping described here is a novel application of our technology that contributes to solving unique scientific questions, and illustrates one of the areas of growth for OGM that the research market provides. We are excited about the possibilities for improved insight in cancer biology and the potential discoveries of novel treatments for cancer that this application could enable.

"I didn't really want my daughter to be spending time on some of the we found early on in the pandemic.

Instead, we're playing catch-up and trying to put bandaids on issues that perhaps could have been avoided if initial design and launch placed kids and teens at the center."

As Zigazoo grows through word of mouth, it has also fallen into the hands of celebrity parents -- including Rutler and his partner, singer Christina Aguilera -- whose 6-year-old daughter consumes videos on the app. "There's nothing else out there like this at all in the kids education space," said Rutler on why he wanted to invest. "I didn't really want my daughter to be spending time on some of the [apps] we found early on in the pandemic. I love that there are more exciting options now."

Elergsma believes existing social media platforms and other apps for kids can look to Zigazoo as an example of how to offer a social yet safe place for children to be online.

"Kids aren't messaging each other, responding to lots of notifications, trying to get 'Zigazoo famous,' shop within the app, meet strangers, or doing any of the other things that make TikTok popular," Elergsma said. "Because Zigazoo encourages offscreen exploration and learning and then allows kids to show what they discovered, it strikes a great balance. It's absolutely okay for kids to be on apps like this."

Insights on the Synthetic DNA Global Market to 2027 - Featuring Codexis, Creative Enzymes and Cyrus Biotechnology Among Others - WFMZ Allentown

A federal court of appeals turned down a request by death row inmate Rodney Reed in a late Thursday ruling that could prove fatal to a years-long efforts to clear his name and overturn his conviction.

In a first-ever attempt to address the issue, a trio of judges appointed by Ronald Reagan, George W. Bush and Barack Obama struck a significant blow against efforts to DNA test murder weapons.

The three-judge panel of the U.S. Court of Appeals for the Fifth Circuit ruled that an August 2019 lawsuit filed against Bastrop County District Attorney Bryan Goertz must be dismissed because Reeds claim is barred by the statute of limitations.

The high-profile inmate sued Goertz under 42 U.S.C. 1983, a Civil Rights claim, based on the idea that prosecutors had violated his First, Fourth, Fifth, and Eighth Amendment rights by refusing to conduct DNA testing on belt used to strangle and kill 19-year-oldStacey Stites.

The DAs office has long opposed efforts by Reed and his attorneys to test the belt and other crime scene evidence for DNAarguing that the results of such testing are not particularly trustworthy.

Specifically, Reed is challenging the applicability of Texass post-conviction DNA statute, Chapter 64, as it was applied to him by Lone Star State courts on appeal. The appeal directly calls into question Goertzs decision to forego a regime of DNA testing on multiple pieces of evidence that could be potentially exculpatory.

In state court, Reed asserted that he was entitled to post-conviction DNA testing of certain evidence, the nine-page opinion explains. The Court of Criminal Appeals rejected Reeds request for post-conviction DNA testing. In these proceedings, Reed challenges the constitutionality of [Chapter] 64 both on its face and as interpreted, construed, and applied by the state court.

Circuit Judge Jennifer Walker Elrod, writing for the court, said that Reeds objections were simply lodged too late.

Section 1983 claims are subject to a states personal injury statute of limitations, Elrod determined. In Texas, the statute of limitations for personal injury claims is two years. As such, Reed cannot assert any claims that accrued prior to August 2017.

The court decided the issue here after crafting a question that produced a result unfavorable to Reed.

The question in this case is when Reed had sufficient information to know of his alleged injury, Elrod wrote.

Heres how the three-judge panel came down:

Reed alleges that he was denied access to the physical evidence that he wished to test. An injury accrues when a plaintiff first becomes aware, or should have become aware, that his right has been violated.Here, Reed first became aware that his right to access that evidence was allegedly being violated when the trial court denied his Chapter 64 motion in November 2014. Reed had the necessary information to know that his rights were allegedly being violated as soon as the trial court denied his motion for post-conviction relief.

Reed, on the other hand, argued that the statute of limitations only began to run when the Texas Court of Criminal Appeals denied his motion for reconsideration. Notably, the district court agreed with the defenses understanding of this discrete issuethough they denied him relief on other grounds. Goertz argued for a statute of limitations defense and the appellate court took his argument to heart.

Reed could have brought his claim the moment the trial court denied his Chapter 64 motion because there was a complete and present cause of action at that time [in 2014], Elrod writes. Because Reed knew or should have known of his alleged injury in November 2014, five years before he brought his 1983 claim, his claim is time-barred.

The defendant still has at least one extant avenue for potential salvation left: a case in the Texas court system based on a habeas corpus petition is currently ongoing. In that filing, Reeds defense is still proceeding at the trial court leveland is the reason hes still alive.

Based on that in-progress case, the Texas Court of Criminal Appeals paused Reeds scheduled execution five days before he was slated to be killed by the state in 2019. In January of this year, Visiting Judge Doug Shaver set a tentative Aug. 31 deadline for the trial courts investigation.
