OBJECTIVE: To investigate the effects of β-(3,4-dihydroxyphenyl)lactic acid on oxidative stress stimulated by high glucose levels in human peritoneal mesothelial cells (HPMCs) in vitro.
METHODS: HPMCs were incubated with 100 mol/l glucose followed by 0.625 - 20 mg/ml β-(3,4-dihydroxyphenyl)lactic acid. Reactive oxygen species (ROS) were quantified by flow cytometry. Relative levels of fibronectin-1 (FN1), collagen-I α(1) (COL1A1), endothelin-1 (EDN1) and haem oxygenase-1 (HMOX1) mRNA and protein were quantified by real-time reverse transcription-polymerase chain reaction and Western blotting, respectively. Absolute levels of FN1 and COLIA1 were quantified by enzyme-linked immunosorbent assay.
RESULTS: β-(3,4Dihydroxyphenyl)lactic acid significantly decreased ROS levels, and EDN1 mRNA and protein levels, in dose- and timedependent manners. HMOX1 mRNA and protein levels were significantly increased by β-(3,4-dihydroxyphenyl)lactic acid in dose-dependent manners. COL1A1 and FN1 mRNA and protein levels were significantly decreased by β-(3,4dihydroxyphenyl)lactic acid in dose- and time-dependent manners.
CONCLUSIONS: β-(3,4-Dihydroxyphenyl)lactic acid inhib ited oxidative stress and reversed increases in FN1 and COLIA1 induced by high glucose levels in HPMCs. This may contribute to a protective role in peritoneal fibrosis.
