木犀草素对大鼠肝肾组织中11β-羟基类固醇脱氢酶的影响
Effect of Luteolin on 11β-Hydroxysteroid Dehydrogenase in Rat Liver and Kidney
摘要
Abstract
[Objective]To investigate the effect of Luteolin on mRNA expression ,protein expression and enzyme activity of 11β-Hydroxysteroid Dehydrogenase (11β-HSD) in rats.[Methods]Twenty-four rats were randomly divided into 4 groups and orally administrated with vehicle(1 % CMC-Na solution)or Luteolin(5,10 or 20 mg/kg daily)for 14 days. Gene expression of 11β-HSD I and 11β-HSD II in liver and kidney was determined with quantitative RT-PCR method. Protein expression was deter-mined with quantitative Western Blot method. The enzyme activity was expressed as the production rate of metabolites of prednisone and prednisolone.[Results]Luteolin significantly induced gene expression of 11β-HSD I and inhibited gene expression of 11β-HSD II in liver tissues ,significantly inhibited gene expression of 11β-HSD I and induced gene expression of 11β-HSD II in kid-ney tissues. Luteolin obviously up-regulated protein expression of 11β-HSD I and down-regulated protein expression of 11β-HSD II in liver tissues ,down-regulated protein expression of 11β-HSD I and up-regulated protein expression of 11β-HSD II in kidney tissues. Luteolin significantly induced activity of 11β-HSD I in liver and11β-HSD II in kidney.[Conclusions]Luteolin could change the activity of corresponding enzyme through affecting gene expression ,protein expression and enzyme activity of 11β-HSD I and 11β-HSD II in liver and kidney tissues in rat ,and affect in vivo activation of glucocorticoids and hormone level in liver and kidney.关键词
