Cardiovascular and Brain Cell Therapy Using Intracellular Ryanodine Receptor Modulation by the Estrogen Receptor Beta

摘要

The present invention includes compositions and methods for screening for a candidate substance with ryanodine receptor (RyR)-modulatory activity, the method including: determining the ion-conducting ability and ability to change the concentration of the free cytoplasmic intracellular Ca²⁺ by the RyR modulated by Estrogen receptor-β (ERβ) in cells or cell membranes expressing RyR and ERβ combination with, or in the absence of the estrogen; contacting the cells or cell membranes with a candidate substance capable of modulation the interaction between RyR and ERβ; and measuring the RyR mediated ion-conducting ability of the cells or cell membranes to change the concentration of the free cytoplasmic intracellular Ca²⁺ by the candidate substance, whereby the modulatory activity of the candidate substance on RyR/ERβ interaction is determined.
