ARID1B and breast carcinoma: Notably, these genes have been previously implicated in promoting tumor progression, invasion, and metastasis in various cancers, including breast cancer.[42, 43, 44, 45, 46, 47, 48, 49] In ARID1B OE MDA‐MB‐468 cells, Flag‐ChIP revealed robust enrichment at all four promoters relative to both IgG control and Flag‐ChIP in control cells (Figure 4I), indicating that ectopically expressed ARID1B is directly recruited to these loci.
