FISH with CD163 labeling showed increased circEML4-positive M2 tumor-associated macrophages in NSCLC tissues from smoking patients compared with non-smoking patients. The study links circEML4 in EVs from M2-TAMs to promotion of NSCLC progression through the SOCS2/JAK-STAT signaling axis.
Smoking-Induced M2-TAMs, via circEML4 in EVs, Promote the Progression of NSCLC through ALKBH5-Regulated m6A Modification of SOCS2 in NSCLC Cells.
