[Injurious effect of zinc deficiency on cardiomyocytes].

The aim of the present study was to investigate the effect of zinc deficiency on cardiomyocyte survival and the underlying mechanisms. Simulated zinc deficiency model was developed in H9c2 cardiac cells with zinc chelator N, N, N', N'-tetrakis (2-pyridylmethyl) ethylenediamine (TPEN). MTT assay was used to evaluate cell viability.
