Abstract: BACKGROUND Calcitriol, the bioactive metabolite of vitamin D, exerts its effects through interaction with the nuclear vitamin D receptor (VDR) to induce genomic responses. Calcitriol may also induce rapid responses via plasma membrane-associated VDR, involving… read more here.

DOI: 10.1152/ajpheart.00117.2017
Abstract: This study shows that in contrast to the rat, mouse ventricular Na+/Ca2+ exchange current density is lower in the t-tubules than in the surface sarcolemma and Ca2+ current is predominantly located in the t-tubules. As… read more here.
