Up till now, there are no researches discussing the role of vinpocetine (VIN) in DOX cardiotoxicity. Thus, the aim of our work was to study this effect and explore the different involved mechanisms.<\/jats:p>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>50 male Wistar albino rats were subjected to DOX toxicity via administration of single i.p. Dose (15\u00a0mg\/kg) on the 4th day with or without co-administration of VIN (10, 20, 30\u00a0mg\/kg\/day) orally for 5\u00a0days.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Our data revealed that VIN succeeded in protecting the heart against DOX induced damage as manifested by significant decrease of cardiac enzymes, hypoxia inducible factor alpha (HIF-1\u03b1), vascular endothelial growth factor-A (VEGF-A), tissue malondialdehyde (MDA), tumor necrosis factor alpha (TNF-\u03b1) and caspase3 levels. Furthermore, VIN given group showed marked improvement of the histopathological changes of cardiac injury, total antioxidant capacity (TAC), elevation of reduced glutathione (GSH), cyclic guanosine monophosphate (cGMP), cyclic adenosine monophosphate (cAMP) and sirtuin-1 (SIRT-1).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>We concluded that VIN could ameliorate DOX induced cardiac damage and this effect may be attributed to modulation of HIF\/VEGF signaling pathway, up-regulation of cGMP\/cAMP\/SIRT pathway, inhibition of phosphodiesterase enzyme, besides its anti-apoptotic, anti-inflammatory, and anti-oxidant properties.<\/jats:p>\n
