[Methylation of nucleic acids and its relation to carcinogenesis (author's transl)]. 1980

C Hanski, and G Stehlik

The physiological methylation of nucleic acids and its relation to their biological function are discussed and compared with the methylation which occurs during chemical, viral and radiation carcinogenesis. The significance of methylated nucleic acid components as cancer markers is evaluated.

UI	MeSH Term	Description	Entries
D008745	Methylation	Addition of methyl groups. In histo-chemistry methylation is used to esterify carboxyl groups and remove sulfate groups by treating tissue sections with hot methanol in the presence of hydrochloric acid. (From Stedman, 25th ed)	Methylations
D009369	Neoplasms	New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.

D001671	Biochemistry	The study of the composition, chemical structures, and chemical reactions of living things.
D012335	RNA, Ribosomal	The most abundant form of RNA. Together with proteins, it forms the ribosomes, playing a structural role and also a role in ribosomal binding of mRNA and tRNAs. Individual chains are conventionally designated by their sedimentation coefficients. In eukaryotes, four large chains exist, synthesized in the nucleolus and constituting about 50% of the ribosome.
