The effect of sPLA2-X expression on cell growth and viability. HEK-293T cells were seeded in 24-well dishes, and the number of viable cells was determined at 0, 24, and 48 h post-transfection with SUMO-PLA2, SUMOstar-PLA2, GFP, or no DNA. Data points represent the average number of viable cells from three independent transfections.
