In The Cancer Genome Atlas (TCGA) and Genomic Spatial Event (GSE) databases, we found that a higher expression of AHR was correlated with a worse prognosis in patients with several cancer types, including breast cancer, lung cancer, glioma, and pancreatic adenocarcinoma (Figure 7A and Supplemental Figure 8A). The gene discussed is AHR; the disease is glioma.
