Research Abstract

Lymphoma (ML) cells transduced with BMI-1 obtained resistance to anti-cancer drugs. Survivin was enhanced in cell lines overexpressing BMI-1. Intriguingly, survivin mRNA was not induced in transduced cell lines, leading to the post-translational regulation involved. The expression of BMI-1 and survivin was much higher in chemotherapy-resistant samples than that in chemotherapy-sensitive.
