Complex formation between calsequestrin and the ryanodine receptor in fast- and slow-twitch rabbit skeletal muscle.

abstract：:Placentas of mice lacking p57(Kip2) expression have trophoblastic hyperplasia. To elucidate the mechanism underlying this phenomenon, we studied expression of two angiogenic factors, vascular endothelial growth factor (VEGF) and placenta growth factor (PlGF). Immunohistochemical analysis with anti-VEGF antibodies indi...
