Abstract

Abstract: Objective To explore the effect and potential mechanism of lncRNA NEAT1 on the invasion and migration of pituitary tumor cells. Methods The expressions of lncRNA NEAT1, miR-134, and ITGB1 were detected by qRT-PCR. Transwell was used to detect the invasion and migration. The regulatory relationship between miR-134 and lncRNA NEAT1 and ITGB1 was detected by a double luciferase reporter gene experiment. The expression of ITGB1/FAK/PI3K pathway-related proteins was detected by Western blot. Results Knockdown of lncRNA NEAT1 inhibited the invasion and migration of GH3 cells (P<0.05); inhibition of miR-134 could reverse the inhibitory effect of down-regulated lncRNA NEAT1 on the invasion and migration of GH3 cells (P<0.05). miR-134 had a negative targeted regulation relationship with lncRNAs NEAT1 and ITGB1 (P<0.05). Up-regulation of miR-134 inhibited the invasion and migration of GH3 cells and inhibited the activation of the ITGB1/FAK/PI3K pathway (P<0.05). ITGB1 overexpression attenuated the effect of up-regulated miR-134 on GH3 cells (P<0.05). Conclusions Down-regulation of lncRNA NEAT1 targeting miR-134 may inhibit the invasion and migration of pituitary tumor cells by inhibiting the activation of the ITGB1/FAK/PI3K pathway.
