Heiko Braak,Eva BraakVSMCs), the opening of BK. channels provides a negative feedback in response to membrane depolarization and increased intracellular calcium. Consequent membrane hyperpolarization and closure of voltage-dependent calcium channels leads to relaxation of VSMCs. In this context, a better understanding o

Living organisms acquire CO by inhalation, by endogenous enzymatic heme degradation catalyzed by heme oxygenases (HOs), or as a byproduct of lipid and xenobiotic metabolism. The HO enzymes exist in both
