ABSTRACT
Objective To investigate the effects of methylthioadenosine phosphorylase (MTAP) on invasion and migration in breast cancer cells.Methods Human breast cancer cell line MCF-7 cells were treated with MTAPtargeted siRNA to diminish MTAP mRNA.MCF-7 cells proliferation was evaluated by cell counting kit-8,the analysis of cells invasion and migration was performed using Transwell chamber.The expressions of MTAP and matrix metalloproteinase 1 (MMP1) in cell extracts were detected by Western blotting.The experimental divided into blank contrd group,negative control group,MTAP-siRNA experimental group.Results The MCF-7 cells growth was promoted after knockdown the MTAP mRNA.MATP-siRNA experimental group 450 nm absorbance values at 24h,48 hand72 h of the control group were (112.3±11.9)%,(144.4±8.4)%,(169.3±9.4)% respectively.Cell invasion analysis by Transwell chamber showed 570 nm absorbance values were 0.49 ± 0.06 (control),0.45 ± 0.07 (negative control) and 0.87 ± 0.07 (MTAP-siRNA) respectively.Cell migration analysis by Transwell chamber showed 570 nm absorbance values were 0.46 ± 0.06 (control),0.49 ± 0.08 (negative control)and 0.75 ± 0.07 (MTAP-siRNA) respectively.The expression of MMP1 in MCF-7 cells was upregulated after knockdown the MTAP mRNA.Conclusion The knockdown of MTAP in MCF-7 cell can increase the cells invasion and migration,and this may involve the the MMP1.
