In HL-1 myocytes, GSK101 triggered Ca2+ influx and evoked the phosphorylation of JNK and CaMKII but these effects were abolished by removing extracellular Ca2+ or in the presence of a TRPV4 antagonist. Finally, we showed that in HL-1 myocytes and isolated hearts during IR, JNK inhibition significantly inhibited the phosphorylation of CaMKII induced by GSK101 but CaMKII inhibition had no effect on JNK activation induced by GSK101. Our data suggest that TRPV4 activation exacerbates myocardial IR injury via the JNK-CaMK
