摘要
The central dogma of molecular biology and genetics considers RNA molecules as mere messengers for decoding genetic information in living cells. 1 Li G.-W. Xie X.S. Central dogma at the single-molecule level in living cells. Nature. 2011; 475: 308-315 Crossref PubMed Scopus (325) Google Scholar However, current knowledge demonstrates the significant influence of RNA biology on genetic, physiological, and biochemical regulation at various stages of disease and development. 2 Barta A. Jantsch M.F. RNA in disease and development. RNA Biol. 2017; 14: 457-459 Crossref PubMed Scopus (6) Google Scholar RNA molecules play a crucial role in shaping intricate cellular systems, specifically in the spliceosome and ribosome assembly. Further, diverse RNA modifications with yet to be fully assigned biological functions underscore the overarching role of ribosomal RNA (rRNA) in framing regulatory networks. Developmental and tissue-specific modification of RNAs, including messenger RNA (mRNA), transfer RNA (tRNA), and rRNA—significantly impacts regulatory processes, facilitating the precise control of several gene-specific pathways. Previous investigations into abnormalities in RNA processing and modifications have resulted in rapid progress in understanding some critical human diseases. 3 Nussbacher J.K. Tabet R. Yeo G.W.
