TP53 and lung carcinoma: In that study, we only used H1299 and H838 cell lines, thus to investigate whether LINC00857 has a broad effect on cancer cell growth; here, we tested 14 lung cancer cell lines representing different histological subtypes (including 13 ADs and 1 SCC) and different genomic alterations, including the EGFR, KRAS, TP53, MET, and LKB11 mutation status (Table S1) using the WST-1 cell proliferation assay following LINC00857 knockdown.
