Mechanism discovered for muscle wasting seen in diabetes, AIDS and other diseases

Early life stress can inhibit development of brain-cell communication zones, UCI study finds
...ups have found that chronic stress causes dendrite atrophy
in adults, but it is not known if CRH plays a role. Yuncai Chen, Roland A. Bender, Kristen L. Brunson and Jrn K. Pomper from the Baram group at UCI collaborated with Dimitri E. Grigoriadis of Neurocrine and Wolfgang Wurst of the Max Planck Institute...

Columbia researchers identify drug as therapeutic candidate for spinal muscular atrophy

Gene with broad role also causes prevalent, inherited nerve disorder
...dependent. The underlying defect in CMT is muscle atrophy
due to a lack of stimulation from the nerves. That lack of stimulation stems from one of two underlying causes, which define the two primary forms of the disease: CMT type 1 and 2. In CMT type 1, the speed of the nerve impulse slows due to degradati...

Chronic inflammation caused by too little stomach acid leads to gastric cancer
...cess begins with chronic gastritis, which leads to atrophy
of the stomach lining, followed by abnormal tissue changes and, finally, the development of malignant cells. "Now we have a mouse model that we can use to isolate the different genetic steps in human gastric cancer," Merchant says. "We've identified ...

Big differences in duplicated DNA distinguish chimp and human genomes
