ABSTRACT

Objective:

This study aims to explore the relationship between serum response factor (SRF) expression level and gas-tric 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 treat-ment 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 close-ly 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.
