Role and Mechanism of Exosome CircRNA Eukaryotic Translation Initiation Factor 4_γ2 (EIF4G2) in Cervical Cancer

Our work was to evaluate Exosome CircRNA EIF4G2 in cervical cancer development. Methods: Using Hela and Siha in our present study. Transfection vector, exosome cirEIF4G2, exosome si-NC or exosome si-circEIF4G2 in cells. Using RT-qPCR to measure circEIF4G2 gene expression in difference cell groups. Evaluating cell proliferation, apoptosis, invasion and wound healing rate by MTT, flow cytometry, transwell and wound healing assay. The relative proteins, HPV16 E6 and HPV16 E7, were evaluated by WB assay. With Exosome CircRNA EIF4G2 transfection, Hela and Siha cells proliferation, invasion cells number and wound healing rates were significantly increased and cells apoptosis were significantly depressed (P < 0.001, respectively) with HPV16 E6 and HPV16 E7 proteins expression were significantly up-regulation (P < 0.001, respectively). However, with Exosome si-CircRNA EIF4G2 transfection, Hela and Siha cells proliferation, invasion cells number and wound healing rates were significantly depressed and cells apoptosis were significantly increased (P < 0.001, respectively) with HPV16 E6 and HPV16 E7 proteins expression were significantly down-regulation (P < 0.001, respectively).
