(A), RT–qPCR was used to detect the expression of different genes in LUAD and normal cells. (B), RT–qPCR was used to detect the expression of different genes in COPD and normal cells. “*” p < 0.05, “**” p < 0.01, “***” p < 0.001. COPD: chronic obstructive pulmonary disease; LUAD: lung adenocarcinoma; RT-qPCR: Real-time quantitative reverse transcription PCR.
