Abstract:Ca2+ is a fundamental determinant of survival in living cells. Excessive intracellular Ca2+ causes cellular toxicity and death but the genetic pathways contributing to Ca2+ induced cell death are incompletely understood. Here, we performed genome-wide CRISPR knock-out screening in human cells challenged with the Ca2+ ionophore ionomycin and identified genes and pathways essential for cell death after Ca2+ overload. We discovered 115 protective gene knockouts, 33 of which are non-essential genes and 21 of which… Show more
