[UNIFESP]; Jurkiewicz, Aron [UNIFESP]; Garcia, Antonio G.; Padin, J. Fernando (Lippincott Williams & Wilkins, 2017)Objective:It has been suggested that Ca2+ entry through store-operated Ca2+ channels (SOCs) is regulated by a dynamic interplay between the endoplasmic reticulum Ca2+ stores and the mitochondria. These relationships drive ... -
