AGO2 and colorectal carcinoma: Thus, the occupancy of Ago2 in the region of circPRMT5 was analysed by using RNA immunoprecipitation and showed that endogenous circPRMT5 pulled‐down from Ago2 cells was specifically abounded, indicating that circPRMT5 could incorporate into the RNA‐induced silencing complex in CRC (Figure 3C).
