Change in charge of an unvaried heme contact residue does not cause a major change of conformation in cytochrome c.

abstract：:The present one-drug-one-target paradigm in drug discovery has been considered partially responsible for the more-funding-less-drug predicament in modern pharmaceutical industry. To hit the multiple targets implicated in complex diseases, two strategies, based on multicomponent or single-ingredient, are conceivable. A...

The brown adipocytes of obese rats have lower Bcl-2/Bax mRNA and protein ratios than those of their lean littermates. Exposure to a low temperature for three days markedly increased the Bcl-2/Bax ratio, by increas...
