Abstract:
Objective:To observe the biological behaviors of colorectal cancer LS174 cells before and after pcDNA3.0-hugl-1 transfection,so as to investigate the association of hugl-1 with colorectal cancer.Methods:The eukaryotic expression vector pcDNA3.0-hugl-1 was constructed and transfected into LS174 cells.RT-PCR and Western blotting methods were used to analyze the expression of hugl-1 mRNA and protein in LS174 cells before and after transfection.Soft agar colony formation assay,wound-healing experiment,adhesion assay and Matrigel invasion assays were used to study the effects of hugl-1 expression on the proliferation,adhesion,movement and invasion in LS174 cells.Results:The recombinant plasmid pcDNA3.0-hugl-1 was successfully constructed.RT-PCR and Western blotting showed that the hugl-1 expression was higher in cells transfected with pcDNA3.0-hugl-1 than in those un-transfected or empty vector-transfected cells (P
