Two-color quantitative multiplex methylation-specific PCR.

In recent years, several methylation-specific PCR-based techniques have been developed to identify and characterize hypermethylation of CpG dinucleotides with the primary goal of elucidating a better understanding of the role of DNA methylation in important biological processes, such as chromosome X inactivation and carcinogenesis. The specificity of methylation-specific PCR (MSP) techniques re...

Two Steps Methylation Specific PCR for Assessment of APC Promoter Methylation in Gastric Adenocarcinoma

Gastric Cancer (GC) is the second most common cancer in the world and a leading cause of cancer-related mortality. Methylation of promoter CpG islands (CGIs) belonging to tumor suppressor genes causes transcriptional silencing of their corresponding genes leading to carcinogenesis and other disorders. Adenomatous Polyposis Coli (APC) a tumor suppressor gene is inactivated by methylation of prom...

Methylation-specific PCR.

Methylation of the DNA is an important epigenetic (i.e., not associated with alteration in the primary structure of the DNA) phenomenon, which plays important roles in regulation of gene expression, maintenance of genome integrity, and genomic imprinting. Although not only other nucleotides, but also proteins and lipids can be methylated, in the context of the present discussion, “methylation” ...

Methylation-Specific PCR Unraveled

Methylation-specific PCR (MSP) is a simple, quick and cost-effective method to analyze the DNA methylation status of virtually any group of CpG sites within a CpG island. The technique comprises two parts: (1) sodium bisulfite conversion of unmethylated cytosine's to uracil under conditions whereby methylated cytosines remains unchanged and (2) detection of the bisulfite induced sequence differ...

Quantitative multiplex methylation-specific PCR assay for the detection of promoter hypermethylation in multiple genes in breast cancer.

If detected early, breast cancer is eminently curable. To detect breast cancer in samples with little cellularity, a high level of sensitivity is needed. Tumor-specific promoter hypermethylation has provided such a valuable tool for detection of cancer cells in biological samples. To accurately assess promoter hypermethylation for many genes simultaneously in small samples, we developed a novel...
