Abstract

Methylation specific PCR (MSP) is a technique that enables the detection of hypermethylation at a CpG island. The objective of this study is the introduction of small modifications to the MSP technique to make it more suitable for the study of promoter hypermethylation at tumor suppressor genes whenever there is a shortage of material available for study. This commonly happens in the case of using archival material from the Pathology departments. Tumor DNA was extracted from a collection of 40 fresh-frozen soft tissue sarcomas and 19 paraffin-embedded PNETs (primitive neuroectodermal tumors). The MSP technique was performed to detect hypermethylation at the p16 promoter. Also, blood genomic DNA was mixed with herry sperm genomic DNA as a carrier, in nine different combinations, in order to test for the best conditions that could produce MSP bands even when low amounts of genomic tumor DNA is available for study. We demonstrate the benefit of using herry sperm carrier DNA up to 10 μg together with small quantities of tumor DNA. This result will facilitate the incorporation of paraffin-embedded samples for study of promoter hypermethylation at tumor suppressor genes. Other technical conditions for the MSP technique are also studied.
