Enzyme-linked immuno-sorbent assay (ELISA) is widely used for biomarker detection. A good biomarker can distinguish patients from healthy or benign diseases. However, the ELISA method is not suitable for small molecule or trace substance detection. Along with the development of new technologies, an increasing level of biomaterials, especially small molecules, will be identified as novel biomarkers...
To demonstrate the diagnostic significance of methylation, an important molecular event in gastric carcinogenesis.We used methylation microarray to determine candidate genes, and performed MSP to evaluate the methylation status of them in tissues and sera. The effect of demethylation on mRNA expression was investigated by rt-PCR after gastric cancer cell lines were treated with 5-Aza-dC for 96h.In...
