For example, Luo et al. performed the WGCNA analysis in pan-cancer diseases including kidney renal clear cell carcinoma (KIRC), breast invasive carcinoma (BRCA), brain lower grade glioma (LGG), kidney renal papillary cell carcinoma (KIRP), liver hepatocellular carcinoma (LIHC), thyroid carcinoma (THCA), Sarcoma (SARC), as well as lung adenocarcinoma (LUAD) respectively to explore the relationship between coexpression modules and telomerase reverse transcriptase (TERT) expression levels in pan-cancer [15]. The gene discussed is TERT; the disease is sarcoma.
