Popis: Objective To explore the effects and mechanism of LASP1 gene expression on the proliferation, migration, and invasion of human colorectal cancer (LOVO) cells. Methods LASP1 overexpression plasmids and LASP1 interference plasmids were constructed and transfected to LOVO cells. qRT-PCR was used to detect LASP1 mRNA expression and validate the transfection. MTT method and Tunel staining were used to detect cell proliferation and apoptosis, respectively, and scratch test and Transwell test were employed to determine the migration and invasion abilities of cells. Western blot was applied to analyze the expression of LASP1, p-FAK/FAK, and p-AKT/AKT protein in cells. Results The plasmids were successfully transfected. LASP1 overexpression increased the proliferation, migration, and invasion of LOVO cells, decreased the apoptosis, and increased LASP1, p-FAK/FAK, p-AKT/AKT protein expression (P < 0.01). LASP1 knockdown reduced the proliferation, migration, and invasion of LOVO cells, increased the apoptosis, and decreased LASP1, p-FAK/FAK, and p-AKT/AKT protein expression (P < 0.01). Conclusion LASP1 positively regulates the FAK/AKT signaling pathway to promote the proliferation, migration, and invasion of LOVO cells.
