Figure 7. MiR-497 mimics inhibited NFκB1-induced resistance to gemcitabine in pancreatic cancer cells. CSCs and non-CSCs derived from populations of AsPC-1 or BxPC-3 cells were transfected with the NFκB1 overexpression vector, empty vector alone, or in combination with miR-497 mimics and then exposed to gemcitabine. After 24 h of treatment, cell viability was examined by the CCK-8 assay. **p < 0.01, compared to the Vect + gemcitabine group; #p < 0.05, compared to the NFκB1+gemcitabine group. Vect, empty vector; CSCs, cancer stem cells.
