ROR1 regulates ABCB1 protein and mRNA expression. (A) Immunoblot assessing ROR1 and ABCB1 protein expression after ROR1 knockdown via siRNA (top panel) or ROR1 inhibition with StrC (bottom panel) in MDA-MB-231. Full length blots are presented in the Supplementary Fig. S9. (B) Immunofluorescence labelling ABCB1 in SUM-159PT/R cells transfected with either siROR1 or scRNA (C,D) qPCR investigating ROR1 and ABCB1 mRNA levels in MDA-MB-231 following ROR1 knockdown via siRNA (B) or inhibition with StrC (C). Statistical analyses via student’s t test. N = 3. ****p < 0.0001.
