Construction of recombinant human IFNα-2b BCG and its antitumor effects on bladder cancer cells in vitro

E. Sun, Nian, X., Liu, C., Fan, X., and Han, R., Construction of recombinant human IFNα-2b BCG and its antitumor effects on bladder cancer cells in vitro, vol. 14, pp. 3436-3449, 2015.

We constructed recombinant Bacille Calmette-Guérin (rBCG) that secreted human interferon alpha 2b (hIFNα-2b), and investigated its antitumor effects on bladder cancer cells in vitro. The recombinant plasmid phIFN-α-2b was constructed using pMAO-4 and transformed into BCG. The supernatant was collected at various times and IFN-γ, interleukin (IL)-12, and tumor necrosis factor (TNF)-α were detected using an enzyme-linked immunosorbent assay. EJ cells were cultivated for 24, 48, and 72 h, together with rBCG, wild-type BCG (wBCG), or wBCG+IFN-α-2b.
