Abstract:

BACKGROUND: Breviscapine has been shown to impact the reproductive capacity in rats with type 2 diabetes mellitus, but few reports concerned its mechanism of action.
OBJECTIVE: To study the effects of breviscapine on proliferating cell nuclear antigen and proto-oncogene c-fos expression in testis of type 2 diabetes mellitus rats.
METHODS: Totally 36 healthy male rats were randomly divided into control group, model group and breviscapine group with 12 rats in each group. In the model group and breviscapine group, rat models of type 2 diabetes mellitus were established by continuous intraperitoneal injection of streptozotocin. Blood glucose reaching16.7 mmol/L in rats was considered as the standard of model induction. In the control group, rats were given an equal volume of citrate buffer solution by single intraperitoneal injection. In the breviscapine group, rats were administered breviscapine 10 mg/(kg•d) for 4 consecutive weeks by intraperitoneal injection. Rats in the other two groups were injected with an equal volume of physiological saline at the same time point.
RESULTS AND CONCLUSION: After 4 weeks of intervention, serum testosterone testing, immunohistochemistry and PCR results showed that serum testosterone levels, proliferating cell nuclear antigen, c-Fos protein and mRNA expression: control group > breviscapine group > model group (P < 0.05); blood glucose concentration: the control group < breviscapine group < model group (P < 0.05). Results confirmed that breviscapine can protect the reproductive function in type 2 diabetes mellitus rats by enhancing the expression of proliferating cell nuclear 
antigen and c-fos.
