Abstract:
Objective This study aims to explore the relationship between serum response factor (SRF) expression level and gastric cancer progression by detecting SRF expression level in cancer cells.
Methods The SRF gene in SGC-7901 cells was silenced by RNA interference.Transfection efficiency was detected by fluorescence microscopy, cell proliferation by CCK 8 method, SRF gene and protein expression level by real-time polymerase chain reaction and Western blot, and cell cycle by flow cytometry.
Results Cell treatment with siRNA-SRF induced significant reduction in SRF mRNA levels.Western blot analysis showed that SRF protein decreased by 40.1% in the siRNA group compared with that in the control group (P < 0.05).Compared with the blank, negative, and mock transfection control groups, cell proliferation of the siRNA-SRF group decreased.The inhibition ratio reached 64.24%, as measured by the CCK-8 assay (P < 0.05).Treatment with siRNA could block SGC-7901 cell cycle at G0/G1 phase (P < 0.05).
Conclusion SRF expression is closely associated with gastric carcinoma cell proliferation.SRF protein level detection can provide a certain reference value in evaluating malignant gastric carcinoma progression.SRF is possibly an important target for the prevention and control of gastric cancers.
