RAB22A and colorectal carcinoma: Our study indicated that MCF2L-AS1 could accelerate cell proliferation, migration, invasion and EMT progression, while reduced cell apoptosis via regulating the miR-105-5p/RAB22A axis in CRC, which suggested that MCF2L-AS1 could be treated as a novel biomarker as well as a therapeutic target for CRC treatment in the future.
