Likewise, Wu et al.24 used a gene list of 10 core clock genes (Table 2) on public human gene expression data and found lower coefficients of variation when they compared cancer samples and normal samples in lung cancer (TCGA-LUAD, GEO-LUAD), kidney cancer (TCGA-KIRC, GEO-KIRC), thyroid cancer (TCGA-THCA), liver cancer (TCGA-LIHC), breast cancer (TCGA-BRCA), and prostate cancer (TCGA-PRAD). This evidence concerns the gene CLOCK and lung carcinoma.
