Abstract_FL Objective:To discuss the effect of curcumin on the proliferation,migration,and invasion of the human prostate cancer C4-2 and LNCaP cells,and to clarify its possible mechanism.Methods:The lentiviral transfection system was used to transfect the C4-2 and LNCaP cells,regarded as shCD147-C4-2 group and shCD147-LNCaP group.RNA interference technology was used to prepare the CD147-silenced cells;the cells transfected with an empty vector were regarded as negative control and divided into shNC-C4-2 group(shNC-C4-2 cells)and shNC-LNCaP group(shNC-LNCaP cells).The C4-2 and LNCaP cells at logarithmic growth phase,as well as shCD147-C4-2 and shCD147-LNCaP cells,were treated with 20 μmol·L-1 curcumin.The morphology of the cells in various groups was observed under microscope at 0 and 24 h of treatment;MTT method was used to detect the proliferation activities of the cells in various groups;cell scratch assay was used to detect the migration rates of the cells in various groups;Western blotting method was used to detect the expression levels of apoptosis,invasion,and migration-related proteins in the cells in various groups.Results:Compared with C4-2 group,the expression of CD147 protein in the cells in shCD147-C4-2 group was significantly decreased after CD147 gene silenting.Compared with LNCaP group,the expression level of CD147 protein in the cells in shCD147-LNCaP group was significantly decreased after CD147 gene silenting.Compared with 0 h of treatment,some cells in C4-2 and LNCaP groups after 24 h of treatment with 20 μmol·L-1 curcumin,showed apoptosis signs with the presence of typical apoptotic bodies.The apoptotic phenomena in shCD147-C4-2 and shCD147-LNCaP groups was reduced.The MTT assay results showed that compared with C4-2+0
