K. HIF-1α overexpression rescues siMCU-mediated migration impairment. Cells were transfected with siMCU or siControl. Wild type (wt) and constitutively active (ca) HIF-1α were expressed by retroviral infection (pBABE was used as control). The day after transduction, cells were scratched (time-point 0h). Cell migration into the wounded area was monitored at 48 hour time-point and the covered area was measured (n=12). P-values: ***p<0.0001, *p=0.04.
