Abstract:
OBJECTIVETo study the effect of Bushen Tiaojing Recipe (BTR) and Xiaoyao Pill (XP) on cathepsin-L (Cat-L) mRNA in mice.
METHODSImmature mice were randomly divided into the normal group, the control group, the BTR group and the XP group, three in each group. Cat-L mRNA expression in mice was detected using reverse transcription polymerase chain reaction (RT-PCR) at 0, 4, 8 and 12 h after injecting 5 IU (human chorionic gonadotropin, HCG).
RESULTSCat-L mRNA expression increased gradually after HCG injection, the relative levels in the control group at 0, 4, 8 and 12 h were 0.066 +/- 0.005, 0.383 +/- 0.045, 0.737 +/- 0.024 and 1.036 +/- 0.073 respectively, comparisons between different time-points showed significant difference (P < 0.01). Compared with the control group, the Cat L mRNA expression was higher at 4 h in both BTR and XP groups (P < 0.01), at 8 h in the XP group (P < 0.05), and at 12 h in BTR group after injecting HCG (P < 0.05). Compared with the control group, cat L mRNA expression showed no statistic difference at 8 h in BTR group and at 12 h in XC group.
CONCLUSIONSBTR promoted the ovulation by enhancing the expression of CatL gene, and that of XP by advancing the peak of CatL gene expression.
