Figure 1. Heterogeneous expression of ABC transporters and Twist1 in different colon cancer cells.
(A) Basal relative mRNA expression of ABC transporters and Twist1 in immortalized NCM460, low-invasive (HT-29) and high-invasive cell types (HCT-8). (B) Vincristine treatment upregulates ABC transporter and Twist1 expression in invasive HCT-8 cells.
