Association between methylation of SHP-1 isoform I and SSTR2A promoter regions with breast and prostate carcinoma development.


PMID 25635370

Abstract

Methylation pattern is presented here for first time as a potential molecular marker of changes on SSTR2A and SHP-1(I) gene promoter related to breast and prostate carcinoma. Our results have shown low concordances with SSTR2A and methylated state in prostate cancer and moderate relationship with unmethylated CpG-27 in breast cancer. We found significant concordances for both cancers and SHP-1(I) unmethylation, and increased HER2 expression and SSTR2A methylation in breast cancer. Moreover, we found a correlation between methylation patterns of two genes in normal breast tissue. These data might assist to select subgroups of patients for the administration of alternative therapies.
