Microarray expression analysis of hearts of zebrafish tremblor mutants at 48 hpf compared to wild-type siblings.


ABSTRACT: Zebrafish ncx1h (also known as slc8a1a) encodes a cardiac specific sodium-calcium exchanger 1 (NCX1h), a primary Ca 2+ efflux effector in cardiomyocytes. The zebrafish tremblor (tre) mutant lacks functional NCX1h and, consequentially, cyclic Ca2+ transients are abolished. In this study, we investigated the effect of aberrant Ca2+ homeostasis in cardiomyocytes on gene expression. Wild type and ncx1 mutant hearts at 48 hours post fertilization were isolated for RNA preparation and gene expression analysis was performed using an Affymetrix Zebrafish GeneChip.
