We analysed the methylation status of the TRNT1 promoter using UALCAN, and the results revealed that TRNT1 promoter methylation was significantly higher in tumour tissues from CHOL, COAD, head and neck squamous cell carcinoma (HNSC), KIRC, kidney renal papillary cell carcinoma (KIRP), and sarcoma (SARC) (Figure S2A), compared to normal tissues. This evidence concerns the gene TRNT1 and neoplasm.
