Effects of probucol on cell proliferation in human ovarian cancer cells.

Probucol is considered to be an important agent in promoting anti-oxidative action and protecting against tissue injury. However, little is known about the effects of probucol on the progression of ovarian carcinoma. The aim of this study was to investigate the effects of probucol on cellular proliferation in human ovarian cancer cells (PA-1 and SKOV-3) and explore the anti-proliferative mechanism of probucol in these cells.

Cinnamaldehyde and nitric oxide attenuate advanced glycation end products-induced the Jak/STAT signaling in human renal tubular cells.

Cinnamaldehyde is a major and a bioactive compound isolated from the leaves of Cinnamomum osmophloeum kaneh. It possesses anti-diabetic properties in vitro and in vivo and has anti-inflammatory and anti-cancer effects. To explore whether cinnamaldehyde was linked to altered advanced glycation end products (AGE)-mediated diabetic nephropathy, the molecular mechanisms of cinnamaldehyde responsible for inhibition of AGE-reduced nitric oxide (NO) bioactivity in human renal proximal tubular cells were examined.

Advanced glycation end products-mediated hypertrophy is negatively regulated by tetrahydrobiopterin in renal tubular cells.

Diabetic nephropathy (DN) is the most common cause of end-stage renal disease worldwide. The accumulation of advanced glycation end products (AGE) is a key mediator of renal tubular hypertrophy in DN. Elimination of tetrahydrobiopterin (BH(4)) and nitric oxide (NO) bioavailability may contribute to the aggravation of DN.
