PLCB1 Enhances Cell Migration and Invasion in Gastric Cancer Via Regulating Actin Cytoskeletal Remodeling and Epithelial-Mesenchymal Transition.

Abstract

Phospholipase C Beta 1 (PLCB1) regulates the abundance of PI(4,5)P2 in the plasma membrane and is implicated in various kinds of cancers. This study aimed to investigate the role and underlying mechanisms of PLCB1 in gastric cancer. Herein, it was found that PLCB1 mRNA and protein were highly expressed in gastric cancer, and high levels of PLCB1 were correlated with poor outcomes of patients with gastric cancer via the GEPIA database. Moreover, our results revealed that PLCB1 depletion inhibited gastric cancer cell proliferation, migration, and invasion. Meanwhile, PLCB1 overexpression resulted in an inverse result. Furthermore, PLCB1 mediated actin cytoskeleton rearrangement and activated the RhoA/LIMK/Cofilin pathway. Besides, PLCB1 promoted the Epithelial-Mesenchymal transition process via activating ATK signaling. In conclusion, PLCB1 promoted gastric cancer cell migratory and invasive abilities via regulating actin cytoskeleton rearrangement and Epithelial-Mesenchymal transition process. These findings imply that targeting PLCB1 may be a potential strategy to improve the prognosis of gastric cancer patients.
