Propranolol affects viability and caspase activation in HeLa cells. HeLa 9XHRE cells were cultured in the absence or presence of propranolol (50 μM or 100 μM). Viability was measured using a CellTiter-Glo assay (a), and apoptosis was measured using a Caspase-Glo 3/7 assay (b). The histograms show an increase in the activation of caspase 3/7 and a reduction in cell viability
