ABSTRACT

Objective:

To investigate the diagnostic value of the promoter methylation of plasma RNF180 gene and its protein ex-pression for the detection of gastric cancer.

Methods:

Methylation-specific polymerase-chain reaction (MSP) and enzyme-linked immu-no-sorbent assay (ELISA) were performed to detect DNA methylation and protein expression of the RNF180 gene, respectively. The correlations of DNA methylation and protein expression of the RNF180 gene with the clinico-pathological parameters of gastric carcino-ma were then separately analyzed.

Results:

MSP showed that the methylation rates of the RNF180 gene were 62.75%and 21.88%in the plasma of patients with gastric carcinoma and healthy volunteers, respectively;this result indicated that the two groups significantly differed (P0.05).

Conclusion:

The RNF180 gene is expressed at a hypermethylation rate, and the corresponding protein expression level is de-creased in the plasma of individuals with gastric carcinoma. Therefore, RNF180 gene methylation in plasma could be applied to detect microinvasion for the clinical diagnosis of gastric cancer.
