Abstract:
Objective To encode the protein cystatin M with CST6 gene and construct a CST6-overexpression vector,and transfect it into the gastric cancer cells SGC-7901 in order to observe the effect of cystatin M on the proliferation and migration abilities of SGC-7901 cells.Methods There were three groups in the experiment:pcDNA3.1(+)-CST6 group,pcDNA3.1 (+)group and non-transfected group.RT-PCR and Western blot were used to identify the RNA expression of CST6 in SGC-7901/CST6 cells.The proliferation and migration abilities of the transfected cells were detected by MTT and cell wound healing assay,respectively.Results SGC-7901/CST6 cells stably expressed CST6 gene RNA and cystatin M protein.The proliferation and migration of pcDNA3 .1 (+)-CST6 group cells were reduced compared with those of cells in the other two groups (P<0.05).Conclusion Cystatin M can inhibit the proliferation and migration of SGC-7901 cells.
