Omega-3 intake significantly reduced cardiovascular risk factors, suppressed inducible VF and facilitated SRR in hypertensive rats. Treatment attenuated lateralization and internalization of Cx43, suppressed elevated Cx43mRNA but enhanced total Cx43 protein expression and/or its functional phosphorylated forms as well as the expression cardio-protective PKC-epsilon and suppressed pro-apoptotic PKC-delta isoform. Moreover, the omega-3 diet normalized MyHC profiles in SHR at early stage of disease and old nonhypertensive rats, but failed to do so in old SHR at late stage of disease
