Abstract

Mitochondrial Ca2+ homeostasis is reported to influence cellular senescence. Here the authors show that TRPC3 limits senescence by inhibiting IP3R-mediated Ca2+ release and ER mitochondria Ca2+ transfer and that the downregulation of TRPC3 in stromal cells affects SASP production and tumour progression.
