Scientists discover the cellular roots of graying hair
Few things about growing older are asinevitable and obvious as “going gray,?yet scientists have been unableto explain the precise cause of this usually unwelcome transformation.In a report posted today on the Web site of the journal Science,researchers from Dana-Farber Cancer Institute and Children’s HospitalBoston say they have found the cellular cause of graying hair whileinvestigating th...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...MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks
Dr. Roger Brent, President and Director of Research at the the release of a new approach to simulation of intracellularbiochemical networks in the January 2005 edition of NatureBiotechnology.The research article, entit...Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows
Researchers using an extremely fast and accurate imaging technique have shed light on the tiny movements of molecular motors that shuttle material within living cells. The motors cooperate in a delicate choreography of steps, rather than engaging in the brute-force tug of war many scientists had imagined. "We discovered that two molecular motors -- dynein and kinesin -- do not compete for...Cellular Defects in Premature Aging Disease are Reversible
Cells affected by Hutchinson-Gilford Progeria Syndrome (HGPS) -- a disease associated with premature aging -- can be made healthy again, according to findings by scientists at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH). Using specially modified segments of DNA, NCI researchers Paola Scaffidi, PhD, and Tom Misteli, PhD, reversed the abnormalities seen in H...Label IT Tracker CX-Rhodamine Intracellular Nucleic Acid Localization Kit from Mirus Bio Corporation

A recent article published by a team in Sweden suggests that there is an increased risk of brain cancer in the areas of highest exposure in patients using digital telephones (Case Control Study on Radiology work, Medical X-Ray Investigations, and Cellular Telephones as Risk Factors for Brain Tumors, Hardell, et al, May 4, 2000, www.medscape.com). Their analysis focused on the effect of different...DNA helps in cellular function
Biological chemists at the University of north Carolina at Chapel Hill, state about the discovery of how living organisms convert genetic instructions into action. The UNC scientists have found a previously unknown chemical site on a key enzyme that regulates production of the genetic messenger known as RNA. When the chemical site is occupied, it markedly speeds up the// process...Researchers Discover Two Proteins Involved In Cellular Destruction Of HIV Virus
Scientists at the Ohio State University have discovered a hitherto unknown mechanism by which cells fight against the invasion of the HIV/AIDS virus. //It was found that two proteins that help in the repair of injured DNA also destroy the DNA of the HIV virus, which is vital for its survival once it enters the cell. The report published in the Proceedings of the National Academy of Scie...Unchecked Cellular Repair Pathway Causes Liver Cancer
Researchers from Duke University Medical Center and John Hopkins University School of Medicine have found that an uncontrolled cell signaling pathway that plays a vital role in the embryonic development and the liver's own response // to injury lead to the development of liver cancer. The cell-signalling pathway called Hedgehog is present only in immature, stem-like liver cells. This di...New Way to Open Cellular Ion Channels, Implications for Drug Design
Using an enzyme found in the venom of the brown recluse spider, researchers at the University of Pennsylvania School of Medicine have discovered a new way to open// molecular pores, called ion channels, in the membrane of cells. The research team – Zhe Lu, MD, PhD; Yajamana Ramu, PhD; and Yanping Xu, MD, PhD of the Department of Physiology at Penn – screened venoms from over 100 pois...Pelvicol Acellular Collagen Matrix (Continence)
