Studies have shown that ARID1A is involved in cell proliferation, migration, and apoptosis and plays a significant role in tumor inhibition (23).ARID1A expression is correlated with cell cycle changes, and the expression of ARID1A is highest in the G0-G1 phase, significantly reduced in the S and G2-M phases, and almost entirely absent in actively dividing cells (33). This evidence concerns the gene ARID1A and neoplasm.
