title: [Experimental study on effect of baoganning on activity of nuclear transcription factor-kappaB in hepatic stellate cells].
abstract: OBJECTIVE
  To investigate the effect of Baoganning (BGN) on activity of nuclear transcription factor-kappaB (NF-kappaB) in hepatic stellate cells (HSCs) and its relevant mechanisms.
  
  
  METHODS
  Normal Wistar rats were medicated with BGN decoction by gavage for 7 days to prepare BGN drug-serum. The effect of BGN drug-serum on HSC-T6 growth was measured by MTT assay; phosphorylation level of NF-kappaB inhibiting factor IkappaB at different time after BGN stimulation was detected by Western blotting analysis; and the binding level of NF-kappaB with DNA was measured 30 min after drug-serum stimulation with gel shift assay.
  
  
  RESULTS
  BGN could significantly inhibit the HSC-T6 growth and quickly supress the phosphorylation of IkappaB, with the effect reached its peak at 30 min and restored to baseline level 6 h after stimulation, and reduce the binding capacity of NF-kappaB with DNA.
  
  
  CONCLUSIONS
  BGN can inhibit phosphorylation of IkappaB, restrain the activity of NF-kappaB and change the binding level of NF-kappaB with DNA.
