Notably, the expression level of NEAT1 positively correlated with the expression levels of angiogenesis-related molecules Sema4D, Plexin B1, Tiam1, and Rac1/2/3 in SKOV-3 and A2780 cells with differentiated expression levels of NEAT1.1 Their correlations were observed in both in vitro cell cultures and xenografted tumor tissues from nude mice. The gene discussed is SEMA4D; the disease is neoplasm.
