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...

MUHC scientists describe genetic resistance to rampant virus

MUHC researchers have defined genetic resistance to the widespread virus, cytomegalovirus (CMV)--a member of the viral group that causes some of the world's most prevalent diseases, such as herpes, chicken pox and mononucleosis. The groundbreaking research published in Nature Genetics last week, provides a roadmap for the development of human therapies for CMV, which could prolong the life of HIV...

FSU biologists describe key role of signal-transcribing gene during cell cycle

Study in Oct. 1 'Development' shows when, where Alzheimer's, some cancers and genetic ills beginT. Biologists at Florida State University have uncovered the pivotal role of a gene called "Cut" that acts as a sort of middleman in cell-to-cell communication. A DNA-binding protein, Cut interprets and transcribes the developmental signals sent through the "Notch" gene, which regulates a layer...

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...

Scientists describe new African monkey genus ?first in 83 years

For the first time in 83 years, scientists have identified a new genus of a living primate from Africa, according to research to be published by Science May 11 in the online Science Express. "This is exciting news because it shows that the 'age of discovery' is by no means over," says William Stanley, a co-author of the study and mammal Collection Manager at The Field Museum, where the w...

Federal advisor to HHS describes the national information infrastructure

MADISON In a speech given April 27, President Bush proclaimed that health care in America is in desperate need of aid, citing a 21st century health care system [which] uses a 19th century paperwork system. While this seems to be a grim statement, Dr. William Yasnoff , a physician and computer scientist who serves as senior advisor for the N...

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, taking part i...

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...

Effects on Breast Tumors of DNA Alternations in 3 Genes Described

Cancer epidemiologists at the University at Buffalohave 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 ver...

Kids Ability to Describe Past Event Develops With Time

A new study has found that kids ability to describe past incidences develops with age . The study was conducted by a team of researchers led by Yael Orbach at the National Institute of Child Health and Human Development and the University of Cambridge. As part of the study, researchers analyzed forensic interviews of 250, 4 to 10-year-old kids who were alleged victims...
