Figure 4From: A mammosphere formation RNAi screen reveals that ATG4A promotes a breast cancer stem-like phenotypeATG4A expression levels in SUM-149 cells. (A) ATG4A mRNA and protein level in cells cultured adherently or as mammospheres. (B) Residual mRNA level of ATG4A following inhibition (shATG4A-1/-2) or overexpression (ATG4A-OE). (C) Residual protein level of ATG4A following inhibition or overexpression. CRTL, control.Back to article page
