STAT3 and non-small cell lung carcinoma: Mechanistically, SNHG3 is activated by E2F transcription factor 1 (E2F1), subsequently promoting proliferation and migration of NSCLC by activating the transforming growth factor‐β (TGF-β), interleukin‐6 (IL-6)/janus‐activated kinase 2 (JAK2)/signal transducer activator of transcription 3 (STAT3) pathways [66].
