LncRNA PCAT6 was highly expressed in lung adenocarcinoma (a-b) GEPIA database showed abnormal expression of lncRNA PCAT6 in various tumors, and increased expression level in LUAD. (c) The expression level of lncRNA PCAT6 in lung adenocarcinoma samples and normal adjacent samples was detected by RT-qPCR. (d) The expression levels of lncRNA PCAT6 in three LUAD cell lines (A549, H1299 and H1975) and healthy BEAS-2B cells were detected by RT-qPCR. (e) Cytoplasmic-Nuclear fractionation was used to detect the proportion of PCAT6 in nucleus and cytoplasm. * p < 0.05, ** p < 0.01, *** p < 0.001
