I-K. Cell proliferation is mainly unaffected by MCU depletion. Cells were transfected with siMCU or siControl. Cell number was counted every 24 hours for 3 days (the 72-hour time point corresponds to the 48-hour time-point of wound healing assay). Results are expressed as ratio R/R0 where R0 is the number of cells at the time of transfection (0 hour time-point) (n=6). P-value: *p=0.05.
