Abstract Cancer drug resistance represents the main obstacle in cancer treatment. Drug-resistant cancers exhibit complex molecular mechanisms to hit back therapy under pharmacological pressure. As a reversible epigenetic modification, N 6 -methyladenosine (m A) RNA modification was regarded be most common modification. methyltransferases (writers), demethylases (erasers), and m A-binding proteins (readers) are frequently disordered several tumors, thus regulating expression of oncoproteins, enhancing tumorigenesis, proliferation, development, metastasis. The review elucidated underlying role A resistance. Alteration affected efficacy by restructuring multidrug efflux transporters, drug-metabolizing enzymes, anticancer targets. Furthermore, variation resulted DNA damage repair, downstream adaptive response (apoptosis, autophagy, oncogenic bypass signaling), cell stemness, tumor immune microenvironment, exosomal non-coding RNA. It is highlighted that small molecules targeting regulators have shown significant potential for overcoming different categories.

Abstract N6-methyladenosine (m6A) is one of the epigenetic modifications RNA. The addition this chemical mark to RNA molecules regulates gene expression by affecting fate molecules. This posttranscriptional modification reversible and regulated methyltransferase “writers” demethylase “erasers”. m6A-modified RNAs depends on function different “readers” that recognize bind them. Research m6A methylation has recently increased due its important role in regulating cancer progression. Noncoding (ncRNAs) are a class transcribed from genome but whose roles have been overlooked their lack well-defined potential for translation into proteins or peptides. However, misconception now completely overturned. ncRNAs regulate various diseases, especially tumors, it confirmed they play either tumor-promoting tumor-suppressing almost all types tumors.

Wilms’ tumor 1-associating protein (WTAP) is required for N6-methyladenosine (m6A) RNA methylation modifications, which regulate biological processes such as splicing, cell proliferation, cycle, and embryonic development. m6A the predominant form of mRNA modification in eukaryotes. WTAP exerts by binding to methyltransferase-like 3 (METTL3) nucleus METTL3-methyltransferase-like 14 (METTL14)-WTAP (MMW) complex, a core component methyltransferase complex (MTC), localizing nuclear patches. Studies have demonstrated that plays critical role various cancers, both dependent independent its methyltransferases.

Abstract Marvelous advancements have been made in cancer therapies to improve clinical outcomes over the years. However, therapeutic resistance has always a major difficulty therapy, with extremely complicated mechanisms remain elusive. N6-methyladenosine (m6A) RNA modification, hotspot epigenetics, gained growing attention as potential determinant of resistance. As most prevalent m6A is involved every links metabolism, including splicing, nuclear export, translation and stability. Three kinds regulators, “writer” (methyltransferase), “eraser” (demethylase) “reader” (m6A binding proteins), together orchestrate dynamic reversible process modification. Herein, we primarily reviewed regulatory resistance, chemotherapy, targeted radiotherapy immunotherapy. Then discussed modification overcome optimize therapy.
