[Effect of Kangquan Recipe on apoptosis regulatory genes bax and bcl-2 mRNA in prostate of rats].

OBJECTIVE

To investigate the effect of Kangquan Recipe (KQR) on apoptosis regulatory genes bax and bcl-2 mRNA in prostate of rats.

METHODS

Benign prostatic hyperplasia model rat was established by injecting testosterone after castration. The model rats were killed and prostate glands were removed for examination after being treated with administration of KQR by gastrogavage for 30 days. The wet weight of prostate was measured and the mRNA expressions of bax and bcl-2 in rats' tissue of abdominal lobe of prostate were determined by RT-PCR.

RESULTS

Compared with the model group, wet weight of prostate was lower significantly in the groups treated with different dosages of KQR (P < 0.05 or P < 0.01), and that in the high dose KQR treated group was similar to that in the normal group (P > 0.05). Compared with the model group, the expressions of bax mRNA and ratios of bax/bcl-2 were significantly higher and the expressions of bcl-2 mRNA significantly lower in the KQR treated groups (P < 0.01), and these indexes in the high dose KQR treated group were insignificantly different from those in the normal group (P > 0.05).

CONCLUSION

KQR shows an obvious treatment effect on rats with benign prostatic hyperplasia, the mechanism might be through effectively regulating the expressions of bax mRNA and bcl-2 mRNA in prostatic tissue to accelerate the cell apoptosis of prostate in obvious dose-effect manner.
