RAC1 and neoplasm: 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.
