TL;DR
Brexpiprazole stops colorectal cancer cells from spreading by blocking a key signaling pathway involved in cell migration and invasion.
Contribution
This study reveals a novel mechanism by which brexpiprazole inhibits cancer metastasis through the SREBP1/SNAI1 pathway.
Findings
Brexpiprazole reduced CRC cell migration, invasion, and metastasis in vitro and in vivo.
SREBP1 directly regulates SNAI1, and brexpiprazole downregulates this pathway.
Brexpiprazole altered the expression of EMT-related proteins like E-Cad and ZO1.
Abstract
To investigate the role and mechanism of the SREBP1/SNAI1 signalling pathway in the effect of brexpiprazole on the EMT and metastasis of CRC. The effects of different concentrations of brexpiprazole on cell migration, cell invasion and protein expression in vitro were examined by cell scratch assays, Transwell assays, Western blotting, ELISA, immunofluorescence, and transmission electron microscopy. A dual-luciferase reporter gene assay was used to assess the interactions between SREBP1 and SNAI1. A model of CRC metastasis in nude mice was established, and Western blotting, HE staining, and PET/CT were utilised to explore the effects of brexpiprazole on CRC lung metastasis. Brexpiprazole significantly inhibited the migration and invasion of CRC cells; downregulated the expression of SREBP1(m), SNAI1 and MMP9; upregulated the expression of E-Cad and ZO1; and decreased the levels of…
