Abstract:
Objective To construct a recombinant eukaryotic vector expressing maspin cDNA,and to explore the effect of maspin overexprssion on the proliferation of human gastric carcinoma cell line SGC7901.Methods The fragment of maspin gene was amplified by polymerase chain reaction(PCR).An eukaryotic vector expressing maspin(maspin/PCR2.1)was constructed with PCR2.1,and transfected into SGC7901 cells.The expression of maspin at mRNA and protein level was detected by RT-PCR and Western blotting.The proliferation of SGC7901 cells was observed by MTT.Cell cycle was analyzed by flow cytometry.Results Recombinant plasmid maspin/PCR2.1 was constructed and transfected into SGC7901 successfully.The mRNA and protein levels of maspin were significantly higher in the maspin/PCR2.1 group(33.6?1.2,23.4?1.6)than that in the blank PCR2.1(15.0?1.5,12.3?1.5)and the untreated group(13.7?2.0,12.0?1.3)(P
