Significance of uncoupling protein 3 in mitochondrial function upon mid- and long-term dietary high-fat exposure.

abstract：:The GTPases of the Rho family are molecular switches that play an important role in a wide range of cellular processes and are increasingly implicated in tumourigenesis. Unlike what was found for the Ras oncogenes in tumours, hardly any activating mutations have been found in the genes encoding Rho proteins. In the pa...
