LncRNA ATB is highly expressed in lung cancer tissues and cancer cell lines. (A) The expression of ATB in lung cancer tissue and paracancerous tissue was detected by RT-qPCR. ***P<0.0001; n=32. (B) RT-qPCR was used to detect the expression of ATB in lung cancer cell line and normal lung epithelial cell line HBE-1, from left to right, P=0.0007, P=0.003, P=0.007, P=0.0045. **P<0.001, ***P<0.0001 vs. HBE-1. LncRNA, long non-coding RNA; RT-qPCR, reverse transcription-quantitative polymerase chain reaction; C, lung cancer tissue; P, paracancerous tissue.
