Scientists discover that three overlapping signals in embryo help get the backbone right

...m to prove that they're essential." In the 1920s, working at the University of Freiburg in Germany, Spemann and his student Mangold found that as the mass of cells in the embryo started to take form, a region in the embryo - what they called the "organizer" - seemed to be the source of signals to nearby cel...

Genetic therapy reverses nervous system damage in animal model of inherited human disease

...umber of injections are necessary to introduce the working LAMAN gene, one of the first steps that will prepare this particular gene therapy for practical use in humans. The gene is transported via a neutralized virus that "infects" cells with the functioning gene. Since the blood-brain barrier would block t...

Study reveals dramatic difference between breast cancers in US and Africa

...stry. Researchers from the University of Chicago, working with colleagues at the University of Calabar in Nigeria and the University of North Carolina, found that breast cancers in African women produce a different pattern of gene expression. Tumors from African women -- from three locations in Nigeria and ...

Study uncovers bacteria's worst enemy

University of California scientists working at Los Alamos National Laboratory have found that the successful use of bacteria to remediate environmental contamination from nuclear waste and processing activities may depend more upon how resistant the bacteria are to chemicals than to how tolera...

Gladstone investigators discover how resting T cells avoid HIV infection

...actor called APOBEC3G (A3G) is the key. The team, working in cell culture, found that A3G exists in two different-sized forms -- a small form that actively repels the virus, and a large form that is completely ineffective against it. Moreover, they detected only the small form in resting CD4 T cells, where ...

Researchers make surprise discovery that some neurons can transmit three signals at once

...eda C. Gillepsie, Ph.D., a post-doctoral associate working with Dr. Kandler, things become more normalized within three weeks of birth, or about one week after hearing is fully developed. So, perhaps early auditory experience provides the signals that stop the cells from releasing glutamate, which is a prere...

The circadian clock: Understanding nature's timepiece

...o shift their body with them so they remain alert, working optimally and making the right decisions." Antle also hopes to experiment further with a technique that involves resetting the circadian clock by altering serotonin levels, the same neurotransmitter that the anti-depressant Prozac targets. He says i...

...s in the timing of sperm or egg development. We're working hard on understanding this mechanism." A similar human equivalent of MSY2, Contrin, has been identified by the research group and their studies indicate it is also a germ cell-specific protein. Using MSY2 as a mouse model, Hecht and colleagues hope ...

Master gene controls healing of skin in fruit flies and mammals

...r injury," said Joseph Pearson, a graduate student working under McGinnis and a coauthor of the paper. "They are activated over many cell diameters, most strongly at the boundaries of the wound, suggesting that the grainyhead gene initiates the cuticle repair response after it receives an as-of-yet unidentif...

Stanford gut check shows diversity of intestinal ecosystem

... analyze samples much more quickly. They have been working with biochemistry professor Patrick Brown, MD, PhD, and graduate student Chana Palmer to develop a gene chip that can perform a microbial census on complex communities and samples. ...

Designing vaccines by computer

...d Biological Sciences Research Council (BBSRC) and working at the Edward Jenner Institute for Vaccine Research are using a very simple concept to help speed up the development of vaccines. They are studying fragments of 'foreign' proteins that have been shown by experiments to effectively trigger a response ...
