FLORENCE COUNTY, SC (WMBF) A DNA test confirms the human remains found along the Big Pee Dee River on May 14 belong to missing woman Angie Pipkin, according to officials.

Preliminary results of the autopsy regarding the skeletal remains found in Florence County confirmed the manner of death was homicide, according to Coroner Keith Von Lutcken.

The remains were found Wednesday, May 14, off Papermill Road in Florence County, near the riverbank of the Great Pee Dee River.

Officials with the Florence County Sheriff's Office and Darlington County Sheriff's Office were on the scene Wednesday, in addition to Florence County Coroner Keith Von Lutcken. Horry County Police Department was also on the scene, Lt. Kegler confirmed.

"Yes, we went there based on the proximity of where the remains were found and the information we obtained during the course of the Angie Pipkin case," Kegler said.

Skeletal samples were sent to the State Law Enforcement Division's DNA Laboratory for analysis.

The DNA testing was done on the remains at the Medical University of South Carolina.

Authorities were in a wooded area, where the remains were found, at about 11 a.m. Wednesday.

People who work at a campground off Papermill Road found the body and called authorities.

Infertility is generally thought of as a womans problem. In fact, more than 3 million men across America also experience it. Today, researchers from Cold Spring Harbour Laboratory describe a key event during sperm development that is essential for male fertility. A team led by CSHL Professor Alea Mills explains how a protein controls DNA packaging to protect a mans genetic information.

The sperm is a simple delivery vehicle for a mans genetic information. The highly specialized cell is little more than a DNA bundle powered by molecular motors. As such, it is necessarily tiny: from head to tail a sperm cell is only about 50 micrometers long (1/500th of an inch), invisible to the naked eye. An egg is 30 times larger. The sperms small size has its benefits less bulk to carry while searching for an egg but it also presents significant challenges. A mans genetic material must be very tightly packaged to fit within a minuscule space.

This organizational problem is not unique to sperm. Every cell in our body contains a full human genome, which spans nearly two meters (6ft) if unfurled. To contain this massive length of DNA, cells tightly compress our genetic information. In every cell nucleus, DNA is wrapped like thread around protein spools, called histones. The thread can be easily unwound at any time to allow access to the genetic information. In sperm, the packaging problem is much more acute, as its DNA is even more condensed. The spool-like histones are replaced with tiny proteins called protamines. This repackaging process, called chromatin remodeling, is absolutely essential for male fertility.

In work published today in Nature Communications, Mills and her team identify a protein, called Chd5, as a key regulator of chromatin remodeling during sperm development. Mills and Wangzhi Li, PhD, lead author on the study, removed both copies of the Chd5 gene from male mice. They discovered that these males had severe fertility defects, ranging from low sperm counts to decreased sperm motility. The defective sperm failed to fertilize eggs when in vitro fertilisation was performed.

Mills has been interested in Chd5 since the time that her team first discovered it in 2007 as a potent tumour suppressor, one that can stop cells from becoming cancerous. We know this ability has something to do with chromatin remodeling that when defective, causes normal cells to transform into tumours, says Mills. But the most dramatic chromatin reorganization occurs when specialized cells carrying our genetic blueprint develop into sperm cells. It makes sense that Chd5 would be functioning there, too.

This, indeed, is what Mills and her team found. When Chd5 is missing, chromatin remodeling is disrupted. Histones are not efficiently replaced with protamines to repackage DNA, resulting in a more uneven, less condensed genome.

This change in DNA packaging has dramatic effects on the DNA itself. In the absence of Chd5, the double helix becomes damaged, breaking at multiple points throughout the genome. So in addition to infertility, loss of Chd5 may put future generations the rare embryos that do get fertilised with defective sperm at risk for disease, says Mills. Chd5 may protect a person from medical conditions related to DNA damage and spontaneous mutations, like cancer and autism.

The team is actively studying the role of Chd5 in human fertility. They analysed Chd5 levels using data from testes biopsies obtained from men with fertility defects. We found that men with more severe defects had the lowest levels of Chd5, says Mills. While it is only a correlation at this point, we are eager to understand fully how Chd5 affects sperm development in humans.
