New insight into cancer metastasis

...ne 25 issue of the journal Cell, the research team headed by Weinberg describes how a breast carcinoma in mice misappropriates a protein called Twist. Twist is a gene regulator, meaning that it tells genes when to turn on and when to turn off. But Twist is mainly active in early embryonic development, where...

Biologists uncover genetic links to broad range of human disorders resulting from cilia dysfunctions

... May 14 issue of the journal Cell, UCSD biologists headed by Charles S. Zuker, a professor of biology and of neurosciences, and postdoctoral fellow Tomer Avidor-Reiss report the identification of some 40 genes that play a role in cilia formation, six of which, they discovered, are essential for the assembly...

Research into cetacean reproduction leads to birth of killer whales by artificial insemination

... in the journal Biology of Reproduction, the team, headed by Dr. Todd R. Robeck, based at SeaWorld San Antonio, notes that their research will allow sperm of killer whales in zoological facilities to be stored by a technique known as "genome resource banking" or GRB. GRB, used in conjunction with artifici...

Researchers find evidence that sea turtles navigate with magnetic maps

...er a century. Now, new findings by a research team headed by Drs. Kenneth and Catherine Lohmann, marine biologists at the University of North Carolina at Chapel Hill, indicate that the navigational ability of sea turtles is based at least partly on a "magnetic map" -- a remarkable ability to read geographic...

Newly discovered gene controls levels of 'bad' cholesterol in mice

... Laboratory of Biochemical Genetics and Metabolism headed by Jan L. Breslow, M.D., the senior author of the study. High levels of LDL cholesterol in the blood lead to heart attacks because the waxy LDL molecules build up inside the walls of arteries, causing damage to the blood vessels and leading to clots...

Alcoholism risk linked to gene involved in brain chemistry

Indianapolis -- A research team headed by Indiana University School of Medicine scientists has identified a gene that is strongly linked to an individual's risk of developing alcoholism. The gene identified, GABRA2, is one of several genes that produce parts of the receptor for the brain'...
