title: [Effect of shenkang injection on transforming growth factor-beta messenger ribonucleic acid of LLC-PK1 renal tubular epithelial cells].
abstract: OBJECTIVE
  To study the effect of Shenkang injection (SKI) on the transforming growth factor (TGF)-beta mRNA of LLC-PK1 renal tubular epithelial cells.
  
  
  METHODS
  Using reverse transcriptase-polymerase chain reaction (RT-PCR) and Northern Blot to observe the effect of SKI on the TGF-beta mRNA of LLC-PK1 renal tubular epithelial cells, with control group treated with the injection of Rheum officinale extraction.
  
  
  RESULTS
  SKI showed the inhibition of TGF-beta mRNA expression of renal tubular epithelial cells, which is dose-dependent and was more obvious than that of the Rheum extractive injection with equal dose of drug.
  
  
  CONCLUSIONS
  The mechanism of delaying chronic renal failure with SKI is achieved by down regulating TGF-beta mRNA expression of renal tubular cells.
