RNA methylations in human cancers
Seminars in Cancer Biology, 2021RNA methylations, as the prevalent post-transcriptional modifications, are critical in regulating various biological processes, such as RNA transcription, splicing, structure, stability, and translation. Its dysregulation is closely related to the occurrence of human malignancies.

AbstractMethylation of RNA occurs at a variety of atoms, nucleotides, sequences and tertiary structures. Strongly related to other posttranscriptional modifications, methylation of different RNA species includes tRNA, rRNA, mRNA, tmRNA, snRNA, snoRNA, miRNA, and viral RNA.

RNA-DNA interactions can serve as a signal that triggers de novo DNA methylation in plants. As yet, this RNA-directed DNA methylation mechanism merely targets transgenes, but it appears likely that methylation of some endogenous sequences is also directed by RNA.

Abstract Several plant and animal viral RNAs contain a tRNA like structure at their 3′ ends. In this communication we show that tobacco mosaic virus (TMV) RNA is an acceptable substrate for a specific tRNA methyltransferase. Using a crude preparation of E. coli ribothymidine (rT) forming uracil methylase and (methyl 3H) S-adenosyl-L-methionine (

Methylation of RNA Purine-Bases by Methyl Radicals
Archives of Biochemistry and Biophysics, 1993During the metabolism of 1,2-dimethylhydrazine (a colon carcinogen) in rats, methyl radicals (.CH3) are produced. To gain an insight into the nature of .CH3 interactions with biomolecules in vivo, we conducted in vitro studies using RNA as a model compound.

A study of transfer RNA methylation
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1973Abstract The process of enzymatic methylation was studied with yeast tRNAVal1, using as a source of enzyme the protein fraction precipitated from the 105 000 × g supernatant of both rat liver and hepatoma by 50 % (NH4)2SO4 saturation. Under the conditions chosen, the extent of methylation with the hepatoma enzyme was about 1 mole of methyl ...

Double-stranded RNAs (dsRNAs) and their `diced' small RNA products can guide key developmental and defense mechanisms in eukaryotes. Some RNA-directed mechanisms act at a post-transcriptional level to degrade target messenger RNAs. However, dsRNA-derived species can also direct changes in the chromatin structure of DNA regions with which they share ...
