biostudies-literatureUnknown11(24)Diling CRecent studies have demonstrated circular RNAs (circRNAs) to be widely expressed and to have important physiological functions. However, the expression, regulation, and function of circRNAs in neuroglial cells are unknown. Herein, we characterized the expression, regulation, and function of circRNAs in astrocytes. Astrocyte circRNAs were identified by computational analysis of newborn SD rat primary astrocytes cultured with 20 g/L D-galactose. In this manner, 7376 circRNAs were identified, among which most circRNAs (5754) were derived from annot_exons, whereas 27 were antisense, 853 were exon/intron, 329 were intergenic, 41 were intronic, and 372 were one exon. Among these, <i>circNF1-419</i> was demonstrated to regulate autophagy, in over-expressing <i>circNF1-419</i> transfected astrocytAging12002-12031https://www.ebi.ac.uk/biostudies/studies/S-EPMC6949063biostudies-literatureCircular RNA NF1-419 enhances autophagy to ameliorate senile dementia by binding Dynamin-1 and Adaptor protein 2 B1 in AD-like mice.PMC6949063Guoyan HYinrui GYizhen XYang BBQingping WTianqiao YDiling CDongdong WYadi LOu SLongkai QXiaocui TXin YfalseCircular RNA NF1-419 enhances autophagy to ameliorate senile dementia by binding Dynamin-1 and Adaptor protein 2 B1 in AD-like mice.Recent studies have demonstrated circular RNAs (circRNAs) to be widely expressed and to have important physiological functions.
