BECN1 and ovarian cancer: Pagotto et al reported that autophagy blockade impairs the canonical properties of ovarian cancer stem cells such as self‐renewal/maintenance rather than proliferation inhibition.16 In our experiments, EOCSCs were transfected with control siRNA (si‐NC), BECN1 siRNA (si‐BECN1), or ATG5 siRNA (si‐ATG5).
