TKT and non-small cell lung carcinoma: The knockdown of SRSF3 increased cellular senescence, indicated by senescence-associated β-galactosidase activity and reduced cell proliferation, in all NSCLC cell lines examined, including A549 (no TK mutation; TP53 wild-type), NCI-H1975 (EGFR L858R/T790M; TP53 R273H mutant), NCI-H322 (no TK mutation; TP53 R248L mutant) and NCI-H596 (no TK mutation; TP53 G245C mutant).
