For example, has_circ_0008234/miR-338-3p/ETS1 axis promotes colon cancer progression56; The has_circ_0008234/miR-204-5p/FGFR2 axis regulates the biological process of gallbladder cancer57; The has_circ_0001944 was found to be highly expressed in colorectal cancer samples and could promote the malignant progression of colorectal cancer by targeting miR-548b-3p58. Here, FGFR2 is linked to malignant colon neoplasm.
