Abstract:
Our experimental study showed that METTL3 was highly expressed in NSCLC cells and promoted the growth of tumor cells. METTL3 takes N6-methyladenosine (m6A) as the main means of mRNA modification to control the expression and function of RIG-I-MAVS signalling pathway. RIG-I-MAVS constitute the first line frontier in the innate immune defense of human cells. Activation of RIG-I-MAVS signaling can inhibit tumor cell growth and activate the immune microenvironment. Our experimental data reveal that lung cancer cells utilize METTL3-mediated methylation modifications to inhibit the activation of RIG-I-MAVS signaling pathway and immune responses. Our work provides new ideas for biotherapy and immunotherapy.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
