Vital step in cellular migration described by UCSD medical researchers
A vital molecular step in cell migration, the movement of cells within the body during growth, tissue repair and the body's immune response to invading pathogens, has been demonstrated by researchers in the University of California, San Diego (UCSD) School of Medicine. Published in the March 27 online edition of Nature Cell Biology and the journal's upcoming April print edition, the study describ...Pathway toward gene silencing described in plants
Biologists at Washington University in St. Louis have made an important breakthrough in understanding a pathway plant cells take to silence unwanted or extra genes using short bits of RNA. Basically, they have made it possible to see where, and how, the events in the pathway unfold within the cell, and seeing is believing, as the old saying goes. Craig Pikaard, Ph.D., Washington Uni...New path from estrogen to survival in breast cancer cells described
After years of research, scientists at The University of Texas M. D. Anderson Cancer Center are now able to explain, in exquisite molecular detail, how the estrogen hormone can help keep breast cancer cells alive. In the Sept. 24 issue of the journal, Nature Cell Biology, they assign roles to a number of genes and proteins thought to play a part in breast cancer cell survival, and in the...Effect on breast tumors of DNA alternations in 3 genes described
Cancer epidemiologists at the University at Buffalo have identified specific genes that are most likely to become cancer promoters when exposed to a process called DNA promoter hypermethylation. Hypermethylation is a process that causes genes that promote normal cell growth to produce proteins that cause malignant behavior, or unregulated cell growth. Until now, data has been very limited...Scientific markers of aging described
According to researchers, low body temperature, low insulin and high levels of a specific hormone seem to be linked to a slowdown of the aging process. It is now well known that calorie restriction// increases the lifespan of animals. Now researchers at the National Institute of Aging have some new clues about slowing down the aging process. They compared a group of 500 healthy men, takin...New Path from Estrogen to Survival in Breast Cancer Cells Described
