Abstract: The content of intermuscular fat is closely related to meat quality,which determines sensory indicators such as flavor,juiciness,and tenderness of pork.Therefore,increasing intermuscular fat deposition plays an important role in improving meat quality.Intermuscular fat deposition is a complex biological process influenced by multiple regulatory factors and lipogenesis-related signaling pathways,among which the role of non-coding RNA (ncRNA) has attracted much attention from researchers. ncRNA is a class of RNA molecules that do not encode proteins,and plays a regulatory role in cell proliferation,differentiation,apoptosis and other biological processes.Recent studies have shown that microRNA (miRNA),long non-coding RNA (lncRNA) and circular RNA (circRNA) are potential regulators of intermuscular fat deposition and are involved in the regulation of fat deposition in animals.The authors summarized the biological characteristics of ncRNA,introduced the origin of intermuscular fat cells,and summarized the current research progress of ncRNA in pig intermuscular fat deposition,in order to provide basic data for pork quality improvement.
