ARHGAP18 and cancer: Examples of this include; (1) the reduction of ARHGAP18 expression by the stable expression of either miR-153 or miR-200b inhibited the cancer cell migration and metastasis in liver and breast cancer cell lines [50,318], (2) the targeting of RACGAP1 by miR-192, -204, or -4324 induced the cell cycle arrest and reduced migration and invasion in osteosarcoma [356], pancreatic [357] and bladder cancer [358], respectively, and (3) the targeting of ARHGAP37 (STARD13) by miR-9 or miR-125b drove cancer cell growth, migration, invasion and metastasis [323,324,325,326].
