pharmacogenomic profiling of the pi3k/pten pathway in sporadic breast cancer
Authors
abstract
background: pharmacogenomics is the study of genetic variations among individuals to predict the probability that a patient will respond to single or multidrug chemotherapy. breast cancer is one of the most common cancers among women worldwide. treatment of breast cancer by application of biological rationales gives us the ability to match the correct pharmacology to individual tumour genetic profiles. the breast cancers exhibit multiple anomalies in phosphatidylinositol 3 kinase pathways, such as phosphatase and tensin homolog deleted on chromosome ten loss that can be put in context of therapy with rapamycin analogues. considering the high incidence of breast cancer in iran, the potential role of tumor suppressor pten/mmac1gene was investigated in isfahanian breast cancer patients. methods: in this study, pten was evaluated by means of polymerase chain reaction, single strand conformation polymorphism, heteroduplex mobility assay and direct dna sequencing in 72 breast cancer tumors for detection and characterization of mutations. results: according to the results of this research, nucleotide substitutions were found in 5/72 (7%) of samples. the sporadic breast cancer patient was found to be heterozygote for the p.d92n, p.c105w, p.d107n, p.a121p and p.r130q mutations. one novel mutation, p.d107n, was found in this study. conclusion: loss of pten function in breast cancer can occur either by mutation or reduction of pten expression in almost half of sporadic breast tumors. this rate of mutations is an important consideration for novel therapeutic in which biological efficacy is influenced by the activity of pten.

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

BACKGROUND Genomic heterogeneity in human cancers complicates gene-centric personalized medicine. Malignant tumors often share a core group of pathways that are perturbed by diverse genetic mutations. Therefore, one possible solution to overcome the heterogeneity challenge is a shift from gene-centric to pathway-centric therapies. Pathway-centric perspectives, which underscore the need to under...

Background: DNA methyltransferase-3B (DNMT3B) is an important enzyme responsible for maintaining the DNA methylation pattern in eukaryotic cells. In this study we have investigated the correlation between the 46359C→T polymorphism in the DNMT3B gene and the risk of breast cancer incidence among sporadic breast cancer patients in Fars Province, Southern Iran.Methods: In this case-control study, ...
