Transforming Growth Factor-β Is an Upstream Regulator of Mammalian Target of Rapamycin Complex 2-Dependent Bladder Cancer Cell Migration and Invasion.

Our prior work identified the mammalian target of rapamycin complex 2 (mTORC2) as a key regulator of bladder cancer cell migration and invasion, although upstream growth factor mediators of this pathway in bladder cancer have not been well delineated. We tested whether transforming growth factor (TGF)-β, which can function as a promotility factor in bladder cancer cells, could regulate mTORC2-dependent bladder cancer cell motility and invasion. In human bladder cancers, the highest levels of phosphorylated SMAD2, a TGF-β signaling intermediate, were present in high-grade invasive bladder cancers and associated with more frequent recurrence and decreased disease-specific survival.

Greater endothelial dysfunction and arterial stiffness in men with chronic prostatitis/chronic pelvic pain syndrome--a possible link to cardiovascular disease.

Purpose: Men with chronic prostatitis/chronic pelvic pain syndrome have higher self-reported rates of cardiac disease than controls. Peripheral arterial tone abnormalities correlate with cardiac disease and mortality. We studied vascular dysfunction in men with chronic prostatitis/chronic pelvic pain syndrome and controls.
