The effect of epigallocatechin-3-gallate (EGCG) on rat mesangial cells (GMCs) proliferation cultured in high glucose condition and the expression of cyclin kinase inhibitor p27(p27) protein were investigated. The GMCs were divided into 6 groups. 48 hours later, the proliferation activity of GMCs was observed by MTT assay, the expression of p27 protein was enhanced by Western blot. Results showed that compared with normal glucose group, high glucose treatment significantly increased GMCs proliferation activity and the expression of p27 protein. EGCG in different concentration suppressed the proliferation of GMCs and down-regulated the expression of p27. It can be concluded that EGCG can suppress the proliferation activity of GMCs cultured under high glucose and decrease the expression of p27 protein, which implied EGCG probably decrease the accumulation of extracellular matrix (ECM) and slowed the progession of progression of glomerular hypertrophy and glomerulosclerosis in diabetic nephropathy.
