Circ-RAPGEF5 promotes intrahepatic cholangiocarcinoma progression by stabilizing SAE1 to facilitate SUMOylation
Abstract Background Intrahepatic cholangiocarcinoma (ICC) is an aggressive malignancy with a poor prognosis.The underlying functions and mechanisms of circular RNA and SUMOylation in the development of ICC remain poorly understood.Methods Circular RNA hsa_circ_0001681 (termed Circ-RAPGEF5 hereafter) was identified by circular RNA sequencing from 19
