Dual effects of veratridine on glucagon and insulin secretion: dependence upon extracellular and intracellular calcium.

abstract：:Women gain weight and their diabetes risk increases as they transition through menopause; these changes can be partly reversed by hormone therapy. However, the underlying molecular mechanisms mediating these effects are unknown. A novel knock-in mouse line with the selective blockade of the membrane-initiated estrogen...
