This study aims to determine the expression of NDRG1 mRNA and protein in gastric cancer cell lines and tissue specimens and then assess the possible cause of its aberrant expression. Six gastric cancer cell lines and 20 pairs of normal and gastric cancer tissue samples were used to assess NDRG1 expression using Real-time PCR and Western blot. High-resolution melting analysis (HRM) and methylation-specific PCR (MSP) were performed to detect gene mutation and methylation, respectively, in cell lines and tissues samples. Expression of NDRG1 mRNA and protein was downregulated in gastric cancer cell lines and tissues. Specifically, expression of NDRG1 mRNA and protein was lower in all six gastric cancer cell lines than that of normal gastric cells, while 15 out of 20 cases of gastric cancer tissues had the reduced levels of NDRG1 mRNA and protein. HRM data showed that there was no mutation in NDRG1 gene, but MSP data showed high levels of NDRG1 gene promoter methylation in the CpG islands in both cell lines and tissue samples. Moreover, treatment with the DNA methyltransferase inhibitor 5-Aza-2'-deoxycytidine upregulated NDRG1 expression in gastric cancer HGC27 cells, but not in the histone deacetylase inhibitor trichostatin A-treated HGC27 cells. In conclusion, this study has shown that expression of NDRG1 mRNA and protein was reduced in gastric cancer cell lines and tissues, which is due to methylation of NDRG1 gene promoter. Further study will unearth the clinical significance of the reduced NDRG1 protein in gastric cancer."xsd:string |
