Invasive cells were counted following 12, 24, 36, and 48 h of incubation where MALAT1-transduced cells (MALAT1) showed significantly increased invasive cell numbers compared to their individual mock-transduced (Mock) and non-transduced parental cells (Parental) controls by crystal violet staining, indicating that MALAT1 overexpression promoted tumor cell invasion in EOCs. The gene discussed is MALAT1; the disease is neoplasm.
