To this end, NQO1-expressing cancer cells were transfected with siCont and pCont, sic-Fos (c-Fos knockdown) and pCont, or sic-Fos and pCKS1B (CKS1B overexpression), and NQO1-deficient cancer cells were transfected with pCont and siCont, pc-Fos and siCont, or pc-Fos (c-Fos overexpression) and siCKS1B (CKS1B knockdown). This evidence concerns the gene NQO1 and cancer.
