To examine the effect of LMP2 and TAP2 on the oncogenesis of cervical cancer cells, the pcDNA3.1-LMP2 and pcDNA3.1-TAP2 plasmids were constructed and transfected into Hela cells, and the ectopic expression of LMP2 and TAP2 was validated by qRT-PCR (Supplementary Fig. 1) and western blotting (Fig. 2A). This evidence concerns the gene PSMB9 and cervical carcinoma.
