cGKIalpha-specific Ca2+ effects in VSMCs remain preclinical; leaves open selective targeting for human vasorelaxation.
Does the cGKIalpha or cGKIbeta isoform mediate NO/cGMP-induced reduction of cytosolic Ca(2+) in vascular smooth muscle cells?
The cGKIalpha isoform, but not cGKIbeta, specifically mediates NO/cGMP-induced reduction of cytosolic calcium in vascular smooth muscle cells, highlighting its distinct role in vasorelaxation.
