Abstract

Background: Cardiomyocyte under hypoxia cause cell death or damage is associated with heart failure. Gap junction, such as connexin 43 play a role in regulation of heart function under hypoxia. Caffeic acid phenethyl ester (CAPE) has been reported as an active component of propolis, has antioxidative, anti-inflammatory antiproliferative and antineoplastic biological properties.

Aims: Connexin 43 appear to have a critical role in heart failure under hypoxia, there has been considerable interest in identifying the candidate component or compound to reduce cell death.

Methods: In this study, we used human cardiomyocyte as a cell model to study the role of connexin 43 in hypoxia- incubated human cardiomyocyte in absence or presence of CAPE treatment.

Results: Results showed that hypoxia induced connexin 43 expression, but not altered in connexin 40. Interestingly, CAPE attenuates hypoxia-caused connexin 43 down-regulation and cell death or cell growth inhibition.

Conclusion: We suggested that reduction of cell death in cardiomyocytes by CAPE is associated with an increase in connexin 43 expression.

Keywords: Caffeic acid phenethyl ester (CAPE), cardiomyocyte, hypoxia, connexin 43.
