Abstract: circRNAs are a subclass of endogenous non-coding RNAs with a closed continuous loop. In recent years, lots of studies have found that circRNAs are ubiquitous in eukaryotes. They not only have certain conserved characteristics and cell specificity, but also play a regulatory role in gene transcription. Regulation of nutrient transport across the placenta is very important for the fetal development, which even determines whether the fetus could be successfully delivered and also affects its future growth and development. Studies in pigs and mice have shown that circRNAs play an important regulatory role in placental nutrient transport and fetal development. This paper reviews the sources, production mechanisms, classification, characteristics and functions of circRNAs. Combined with animal production, the regulation role of circRNAs on nutrient transport of glucose, amino acids and fatty acids in mammalian placenta and fetal development are also reviewed.
