Latest Cell division Stories
Last week, a presidential limousine shuttled Barack Obama to the most important job in his life. Scientists at the Stanford University School of Medicine have now identified a protein that does much the same for the telomerase enzyme â€” ferrying the critically important clump of proteins around to repair the ends of chromosomes that are lost during normal replication. Without such ongoing maintenance, stem cells would soon cease dividing and embryos would fail to develop.
A Florida State University College of Medicine research team led by Yanchang Wang has discovered an important new layer of regulation in the cell division cycle, which could lead to a greater understanding of the way cancer begins.
ROYAL PALM BEACH, Fla., Oct. 9 /PRNewswire/ -- This may sound like science fiction, but it is truly cutting-edge reality. Internationally acclaimed anti-aging Doctor, Al Sears MD, has become the first U.S.
By Don Sapatkin PHILADELPHIA - Emmanuel Skordalakes scrutinized the genetic makeup of pigs and cows and rats and hundreds of other creatures before the red flour beetle, an eighth-of-an-inch-long pest found in Southern kitchens, delivered the breakthrough scientists had sought for more than a decade.
U.S. scientists have found a new mechanism for cell fate determination -- how one cell can differ from another despite having the same genetic material. Northwestern University researchers say their yeast study demonstrates why mothers and daughters differ in gene expression.
The seemingly inefficient way our bodies replace worn-out cells is a defense against cancer, according to new research.
Researchers at the Salk Institute for Biological Studies discovered that cells co-opted the machinery that usually repairs broken strands of DNA to protect the integrity of chromosomes. This finding solves for the first time an important question that has long puzzled scientists.
The continual and inevitable shortening of telomeres, the protective "caps" at the end of all 46 human chromosomes, has been linked to aging and physical decline. Once they are gone, so are we. But there are more ways than one to grow old.
Everyone knows that stem cells are controversial. Many people know that stem cells can grow into virtually any cell type found in the body, from a red blood cell to a muscle cell to a brain cell. But no one really knows why stem cells continue to divide and renew themselves long after the point where other cells stop dividing.
