The role of long non-coding RNAs in intramuscular fat deposition in livestock: Current research

Open Access

Abstract

Meat products are vital components of the human diet, and intramuscular fat (IMF) is a key indicator of meat quality. Long non-coding RNAs (lncRNAs) play essential roles in diverse biological processes. Here, we review current research on the role of lncRNAs in the process of IMF deposition and its impact on meat quality in livestock such as cattle, pigs, sheep, and poultry. The study also presents the characteristics of lncRNAs and their function. LncRNAs serve as regulators in gene expression networks associated with fat deposition. In addition, lncRNAs can promote or inhibit the differentiation of preadipocytes into adipocytes. Studies indicate a potential role for individual lncRNAs in the development of IMF in animals through involvement in signaling pathways related to fat deposition and lipid metabolism. Understanding the regulatory network and the role of lncRNAs in the accumulation of IMF could help improve meat quality, which is of great value to consumers.
