Preprints with The Lancet is part of SSRN´s First Look, a place where journals and other research experts identify content of interest prior to publication. These preprint papers are not peer-reviewed. Authors have either opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet, or submitted directly via SSRN. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These papers should not be used for clinical decision making or reporting of research to a lay audience without indicating that this is preliminary research that has not been peer-reviewed.

Abstract

Background: 5-methylcytosine (m5C) is a reversible modification to both DNA and various cellular RNAs. However, its roles in the development of human cancers are poorly understood, including the effects of mutant m5C regulators and the outcomes of modified nucleobases in RNAs.

Methods: Based on The Cancer Genome Atlas (TCGA) database, we uncovered that mutations and/or copy number variations (CNVs) of m5C regulatory genes were significantly correlated across many cancer types. We then assessed the correlation between the expression of individual m5C regulators and the activity of related hallmark pathways of cancers.

Findings: After validating the expression of m5C regulators based on their contributions to cancer development and progression, we observed their up-regulation within tumor-specific processes. Notably, our research connected aberrant alterations to m5C regulatory genes with poor clinical outcomes among various solid tumors that may drive cancer pathogenesis and/or survival.

Interpretation: We ultimately provide a landscape for the various roles of m5C regulatory genes, offering strong evidence and clinical implications for the involvement of m5C regulators across a comprehensive set of solid tumor malignancies.

Funding Statement: This study was supported by funds from the National Natural Science Foundation of China (81902832 to Y.H. and 81702927 to J.L.); the Science and Technology Research Project of Henan Province (192102310117 to Y.H. and 202102310074 to C.X.).

Declaration of Interests: The authors have no conflicts of interest to report.
