SV40 MES-13 cells were transfected with pcDNA, or pcDNA-GAS5, or pcDNA-GAS5+si-control, or pcDNA-GAS5+si-IKK. Then, SV40 MES-13 cells were divided into NG group, HG group, HG+pcDNA group, HG+pcDNA-GAS5 group, HG+pcDNA-GAS5+si-control group, HG+pcDNA-GAS5+si-IKK group. (A) The proliferation of SV40 MES-13 cells was detected in NG group, HG group, HG+pcDNA group, HG+pcDNA-GAS5 group, HG+pcDNA-GAS5+si-control group, HG+pcDNA-GAS5+si-IKK group. (B) The levels of LN, FN and Col IV were detected in NG group, HG group, HG+pcDNA group, HG+pcDNA-GAS5 group, HG+pcDNA-GAS5+si-control group, HG+pcDNA-GAS5+si-IKK group.** P<0.01, compared with NG. ##P<0.01, compared with HG+pcDNA. &P<0.01, compared with HG+ pcDNA-GAS5+si-control.
