ABSTRACT
Aim To investigate the anti-apoptotic effect of NGF on H9 c2 cardiac myocytes in a hypoxia / reox-ygenation injury model and its mechanism. Methods The H9 c2 cardiac myocytes were randomly divided into five groupscontrol group ( C group) , hypoxia/reoxy-genation group ( H/R group) , NGF group ( N group) , NGF+LY294002 group ( N+L group) and LY294002 group( L group) . Each group received the correspond-ing treatment. Cell survival rate was tested by cell counter kit-8 methods. Apoptotic rate was evaluated by propidium iodide ( PI ) staining and flow cytometry (FCM). The levels of Caspase-12, p-Akt/Akt were e-valuated by Western blot. Results The NGF group could significantly protect the H9 c2 cardiac myocytes under the hypoxia / reoxygenation injury with increased cell survival rate. It also decreased the apoptotic per-centage, upregulated the level of p-Akt/Akt and inhib-ited the expression of Caspase-12 . As the specific in-hibitor of PI3k receptor, LY294002 decreased the level of p-Akt. Conclusion NGF has the effect of anti-ap-optosis on H9 c2 cardiac myocytes exposed to hypoxia /reoxygenation injury via PI3k-Akt signal pathway.
