ABSTRACT
Objective To investigate the effect of baicalain on high expression of ECM and TGF-?1 in proximal tubular epithelial cells cultured in high glucose concentration. Methods LLC-PK1 cells were divided into six groups (1)normal glucose group(NG, 5. 5 mmol/L D-glucose), (2)high glucose group(HG, 25 mmol/L D-glucose), (3) HG + PKC inhibitor(10?mol/L chelerythrine chloride), (4)HG + baicalein(50 ?mol/L), (5) HG + baicalein(100 ?mol/L), (6) HG + baicalein (200 ?mol/L) . PKC activity was detected. Expression of ColⅣ, FN and TGF-?1 was examined by in situ hybridization and immunocytochemistry(ABC) techniques. Results At concentrations of 100 ?mol/L and 200 ?mol/L, baicalein decreased membranous PKC activity in LLC-PK1 cells by 42% and 68% , respectively ( P
