Many translated sORFs have been identified across mRNAs, including 5’-upstream, coding domain, and 3’-downstream. sORFs have also been found in circular RNAs, pri-miRNAs, and ribosomal RNAs. Here, we present an overview of the wide distribution of the sORFs in transcripts and their functional roles in organisms.展开更多

Although miPs are difficult to analyze and identify, a number of studies have begun to focus on them. More and more miPs have been revealed as essential for energy metabolism homeostasis, immune regulation, and tumor growth and development. Many reports have shown that miPs are especially essential for regulating glucose and lipid metabolism and regulating mitochondrial function.MiPs are also involved in the progression of related diseases. This paper reviews the sources and identification of miPs, as well as the functional significance of miPs for metabolism-related diseases, with the aim of revealing their potential clinical applications.展开更多
