How to use

In Vitro:

Parstatin (0-10 µM) increases recovery of LVDP in a concentration-dependent manner. The optimal concentration was 1 µM which produced a 23% recovery of LVDP.

In Vivo:

Parstatin (single dose, 1-25 µg/kg, iv) administered prior to ischaemia confers immediate cardioprotection by recruiting the Gi-protein activation pathway including p38 MAPK, ERK1/2, NOS, and KATP channels. Parstatin exerts effects on both the cardiomyocytes and the coronary circulation to induce cardioprotection. This suggests a potential therapeutic role of parstatin in the treatment of cardiac injury resulting from ischaemia and reperfusion.
