This review describes how a biochemist and basic researcher (i.e. myself) came to make a career in the area of receptor-coupled signal transduction and the roles cellular signaling activities play both in normal physiology and in disease. Much of what has been the best part of this research life is due to the time I spent with Bob Lefkowitz (1982–1985), during an extraordinary period in the emerging...
Recently, the small molecule 968 was found to block the Rho GTPase-dependent growth of cancer cells in cell culture and mouse xenografts, and when the target of 968 was found to be the mitochondrial enzyme glutaminase (GLS1), it revealed a surprising link between Rho GTPases and mitochondrial glutamine metabolism. Signal transduction via the Rho GTPases, together with NF-κB, appears to elevate mitochondrial...
