Environmentally relevant (100 nM) inorganic arsenic (iAs) exposure displaces zinc from zinc fingers of upstream splice regulator ZRANB2 disrupting the splicing of its target TRA2B. Excess zinc displaced iAs from ZRANB2 zinc fingers in cell free system. Thus, the hypothesis that zinc supplementation could prevent iAs-mediated disruption of ZRANB2 splice function in human keratinocytes was tested. The data show that zinc supplementation prevented iAs-induced dysregulation of TRA2B splicing by ZRANB2 as well as the induction of ZRANB2 protein expression. These results provide additional support for the hypothesis that zinc supplementation could prevent iAs-mediated disease in iAs-exposed populations.
