To clarify the role of AhR in NSCLC, we extracted mRNA from clinical non-small cell lung cancer samples for analysis, finding that the AhR mRNA level did not differ between lung adenocarcinoma (ADC; Fig. 1A) and squamous cell carcinoma (SCC; Fig. 1B) tissues and adjacent tissues. The gene discussed is AHR; the disease is non-small cell lung carcinoma.
