TINCR is low expressed in LUAD tissues. A. TINCR was low expressed in LUAD tissues (Left panel), and its expression profiling in LUAD at different stage was visualized (Right panel) according to GEPIA (http://gepia.cancer-pku.cn/detail.php?gene=TINCR). B. TINCR was significantly downregulated in 29 LUAD tissues compared with paired adjacent normal tissues as analyzed by qRT-PCR. Data shown are mean ± standard deviation. Statistically significant differences are indicated as **, P < 0.01; student’s t-test. The experiment was repeated at least three times. TINCR, tissue differentiation-inducing non-protein coding RNA; LUAD, lung adenocarcinoma; GEPIA, Gene Expression Profiling Interactive Analysis; qRT-PCR, quantitative real-time polymerase chain reaction.
