Chen, Huifang published the artcileCross-talk of four types of RNA modification writers defines tumor microenvironment and pharmacogenomic landscape in colorectal cancer, Formula: C28H41N7O4, the publication is Molecular Cancer (2021), 20(1), 29, database is CAplus and MEDLINE.
The four major RNA adenosine modifications, i.e., m6A, m1A, alternative polyadenylation, and adenosine-to-inosine RNA editing, are mediated mostly by the “writer”enzymes and constitute critical mechanisms of epigenetic regulation in immune response and tumorigenesis. However, the cross-talk and potential roles of these “writer”; in the tumor microenvironment (TME), drug sensitivity, and immunotherapy remain unknown. We systematically characterized mRNA expression and genetic alterations of 26 RNA modification “writer” in colorectal cancer (CRC), and evaluated their expression pattern in 1697 CRC samples from 8 datasets. We used an unsupervised clustering method to assign the samples into two patterns of expression of RNA modification “writer”. Subsequently, we constructed the RNA modification “writer”; Score (WM_Score) model based on differentially expressed genes (DEGs) responsible for the RNA modification patterns to quantify the RNA modification-related subtypes of individual tumors. Furthermore, we performed association anal. for WM_Score and characteristics of TME, consensus mol. subtypes (CMSs), clin. features, transcriptional and post-transcriptional regulation, drug response, and the efficacy of immunotherapy. We demonstrated that multi-layer alterations of RNA modification”writer” are associated with patient survival and TME cell-infiltrating characteristics. We identified two distinct RNA modification patterns, characterized by a high and a low WM_Score. The WM_Score-high group was associated with worse patient overall survival and with the infiltration of inhibitory immune cells, such as M2 macrophages, EMT activation, and metastasis, while the WM_Score-low group was associated with a survival advantage, apoptosis, and cell cycle signaling pathways. WM_Score correlated highly with the regulation of transcription and post-transcriptional events contributing to the development of CRC. In response to anti-cancer drugs, WM_Score highly neg. correlated (drug sensitive) with drugs which targeted oncogenic related pathways, such as MAPK, EGFR, and mTOR signaling pathways, pos. correlated (drug resistance) with drugs which targeted in apoptosis and cell cycle. Importantly, the WM_Score was associated with the therapeutic efficacy of PD-L1 blockade, suggesting that the development of potential drugs targeting these “writer”to aid the clin. benefits of immunotherapy. Our study is the first to provide a comprehensive anal. of four RNA modifications in CRC. We revealed the potential function of these writers in TME, transcriptional and post-transcriptional events, and identified their therapeutic liability in targeted therapy and immunotherapy. This work highlights the cross-talk and potential clin. utility of RNA modification “writer”in cancer therapy.
