Cells Send Dirty Laundry Home to Mom
Understanding how aged and
damaged mother cells manage
to form new and undamaged
daughter cells is one of the
toughest riddles of aging,
but scientists now know how
yeast cells do it. In a

Enhancing Arrest of Cell Growth to Treat Cancer in Mice
February 9, 2010 — New research has identified a new type of cellular senescence (i.e., irreversible arrest of cell growth) and determined a way to enhance it to suppress prostate tumor development and growth in mice. ... > full story -
Complete Chemokine Profile of a Cell
February 9, 2010 — Chemokines are a large group of proteins whose predominant function is to direct cell migration. They regulate many physiological and pathophysiological processes, in particular in the immune system. ... > full story -
Argonautes: A Big Turn-Off for Proteins

Transforming Human Fat Into Stem Cells Using Virus-Free Technique
February 8, 2010 — Tiny circles of DNA are the key to a new and easier way to transform stem cells from human fat into induced pluripotent stem cells for use in regenerative medicine, say scientists. Unlike other ... > full story -
A Potent Suppressor of Endometrial Cancer Is Revealed
February 8, 2010 — Treatment of endometrial cancer has not advanced significantly in 30 years and there are no screening tests to promote early detection. Researchers have developed a new approach to specifically ... > full story -
Biologists Determine microRNA Activity Is Suppressed in Mouse Ovum
February 7, 2010 — Scientists studying RNA activity, the so-called dark matter of the biological world, may have found the first event in reprogramming a differentiated oocyte into pluripotent blastomeres of the ... > full story -
World's First in-Depth Study of the Malaria Parasite Genome
February 6, 2010 — Groundbreaking research could lead to the development of more potent drugs or a vaccine for malaria. Scientists have scored a world first in successfully using transcriptional profiling to uncover ... > full story -
Scientists Map out Regulatory Regions of Genome, Hot Spots for Diabetes Genes
February 5, 2010 — Researchers have generated a complete map of the areas of the genome that control which genes are "turned on" or "off." The discovery, made in pancreatic islet cells, opens new avenues for ... > full story -
Molecular Regulator That Controls Ability of Sperm to Reach and Fertilize the Egg Identified
February 5, 2010 — Researchers have identified an elusive molecular regulator that controls the ability of human sperm to reach and fertilize the egg, a finding that has implications on both treating male infertility ... > full story -
Scientists ID a Protein That Splices and Dices Genes
February 5, 2010 — Researchers have discovered that the protein MRG15, which previously had been known to affect cell growth and aging, also directs the gene-splicing machinery. As people or animals age, this machinery ... > full story
