The hyperactivation of STAT3 promotes the expression of genes that are involved in cell proliferation (eg Cyclin D1 and c‐Myc), survival (eg Bcl‐XL and Mcl‐1).23, 30 As DYRK1A could affect the STAT3 pathway in NSCLC, we hypothesized that DYRK1A might also affect the downstream of STAT3. Here, STAT3 is linked to non-small cell lung carcinoma.
