Abstract:

Rivaroxaban (RVX) id used to treat thrombosis however its effect on testicular IR hasnot been investigated yet. This study investigates the effect of RVX on testicular ischemia-reperfusion in rats. Rats were randomly allocated into 4 groups. The sham group, testicular ischemia-reperfusion (IR) group, the remaining 2 groups were treated with RVX in doses of7 and 14 mg/kg, respectively for a week prior IR. Then biochemical parameters were carried out in addition to western blot analysis. RVX-treated groups showed significant reduction in protein expression of hypoxia-inducible factor (HIF-1α) and vascular endothelial growth factor (VEGF) associated with elevation in testosterone level, reduction in malondialdehyde (MDA), elevation in glutathione peroxidase (GPX), reduction in nuclear factor kappa-B p65 (NF-ĸb p65), reduction in Bax (Bcl2-associated X protein) and elevation in BCL2 (B-cell lymphoma 2), content. Moreover, RVX reduced caspase-3 protein expression. It can be concluded that HIF-1α mediated RVX’s anti-oxidant, anti-inflammatory and, anti-apoptotic effect in rats subjected to testicular IR.
