We predicted that circIFNGR2 could sponged miR-30b via bioinformatic method and subsequently confirmed that circIFNGR2 promoted the proliferation and migration of CRC cells by targeting miR-30b/KRAS. In addition, we demonstrated that circIFNGR2 might act as a potential chemotherapy resistance marker in CRC.
CircIFNGR2 enhances proliferation and migration of CRC and induces cetuximab resistance by indirectly targeting KRAS via sponging to MiR-30b.
