Advances of long non-coding RNA encoded micro-peptides

Abstract:

Long non-coding RNA (lncRNA) refers to non-coding RNA longer than 200 nt, with one or more short open reading frames (sORF), which encode functional micro-peptides. These functional micro-peptides often play key roles in various biological processes, such as Ca²⁺ transport, mitochondrial metabolism, myocyte fusion, cellular senescence and others. At the same time, these biological processes play a key role in the regulation of body homeostasis, diseases and cancers development and progression, embryonic development and other important physiological processes. Therefore, studying the potential regulatory mechanisms of micro-peptides encoded by lncRNA in organisms will help to further elucidate the potential regulatory processes in organisms. Furthermore, it will provide a new theoretical basis for the subsequent targeted treatment of diseases and improvement of animal growth performance. This review summarizes the latest research progress in the field of lncRNA-encoded micro-peptides, as well as the progress in the fields of muscle physiological regulation, inflammation and immunity, common human cancers, and embryonic development. Finally, the challenges of lncRNA-encoded micro-peptides are briefly described, with the aim to facilitate subsequent in-depth research on micro-peptides.
