Overexpression of ADRB2 activated JAK2/STAT3 signaling pathway. (A) The significant pathway activated in the high ADRB2 expression group via GSEA enrichment analysis. (B-D) Phosphorylation of JAK2 and STAT3 after overexpression of ADRB2 in A549 cells by western blot analysis. (E-G) Phosphorylation of JAK2 and STAT3 after downregulation of ADRB2 in H1299 cells by western blot analysis. *P <0.05 and ***P < 0.001.
