YAP1 and intrahepatic cholangiocarcinoma: also reported that circACTN4 could sponge miR‐424‐5p to upregulate YAP1, leading to ICC progression.[14] In the current study, circUGP2 was observed in both the nucleus and cytoplasm of ICC cells, and further investigations revealed that ADGRB1 could also be upregulated by circUGP2 through sponging miR‐3191‐5p.
