Circular RNA Cdr1as inhibits proliferation and delays injury-induced regeneration of the intestinal epithelium

JCI Insight
Circular RNAs (circRNAs) are highly expressed in the mammalian intestinal epithelium, but their functions remain largely unknown. Here, we identified the circRNA Cdr1as as a repressor of intestinal epithelial regeneration and defense.
