To investigate the effects of Xiongcan Yishen Prescription (XYP) on the expressions of cholesterol transport proteins, steroidogenic enzymes and steroidogenic factor-1 (SF-1) in the Leydig cells of the rats with late-onset hypogonadism (LOH). Twenty-five 18-month-old male SD rats were randomly divided into five groups of equal number, LOH model control, testosterone propionate (TP) and low-, medium- and high-dose XYP, and another 5 two-month-old male SD rats included as normal controls. After modeling, the animals in the TP group were treated by intramuscular injection of TP at 5.21 mg/kg qd alt, those in the low-, medium- and high-dose XYP groups intragastrically with XYP at 10.4, 20.8 and 41.6 g/kg qd alt respectively, and those in the LOH model and normal control groups with saline, all for 28 successive days. Then, all the rats were sacrificed for determination of the expressions of the cholesterol transport proteins StAR and TSPO, steroidogenic enzymes CYP11A1, HSD3B7 and HSD17B4, and SF-1 in the Leydig cells by Western blot. The expressions of StAR, TSPO, CYP11A1, HSD3B7, HSD17B4 and SF-1 in the Leydig cells were significantly decreased in the LOH model controls compared with those in the normal controls (P< 0.05), but remarkably increased in the low-, medium- and high-dose XYP groups in comparison with those in the LOH model control group (P< 0.05). Xiongcan Yishen Prescription can up-regulate the expressions of the cholesterol transport proteins StAR and TSPO, steroidogenic enzymes CYP11A1, HSD3B7 and HSD17B4, and SF-1 in the rat Leydig cells, which might be one of the possible mechanisms of the prescription in the treatment of LOH.
