Objective: To explore the effect of Tangnaikang (TNK) on the smads signaling pathway of human renal tubular epithelial cells (HK-2) induced by transforming growth factor-β1(TGF-β1). Method: The HK-2 cells were cultured by DMEM/F12(1:1) with 10% fetal bovine serum and divided into control group
TGF-β1 group (TGF-β110 μg·L-1)
rat serum control group(TGF-β110 μg·L-1 +10% rat serum)
TNK -containing rat serum therapy groups (TGF-β110 μg·L-1 + 20% TNK or + 10% TNK or + 5% TNK). After 24 h
the expression of transforming growth factor β receptor I(TβRI)
transforming growth factor β receptor II (TβRII) mRNA were tested by fluorescence quantitatiye PCR assay
and the expression of Smad 2
Smad 3 protein by Western-blot assay. Result: The expression of TβRI
TβRII mRNA and Smad 2
Smad 3 protein of HK-2 cultured with TGF-β1 were much notable than the control
and significantly decreased in HK-2 cultured with TGF-β1 plus TNK compared with only TGF-β1 (P<0.05)
but only rat serum had no such effect. Conclusion: TNK could regulate the smads signaling pathway of human renal tubular epithelial cells HK-2 induced by transforming growth factor-β1
and could prevent the development of renal fibrosis to a certain extent.
