on the one hand circ-0000284 functions as a competitive endogenous RNA to promote cholangiocarcinoma progression, and on the other hand, circ-0000284 can be directly transferred from cholangiocarcinoma cells to surrounding normal cells via exosomes.
Circ-0000284 arouses malignant phenotype of cholangiocarcinoma cells and regulates the biological functions of peripheral cells through cellular communication.
