Gene assembling: a new approach in molecular diagnosis of hereditary breast cancer

gene assembling: a new approach in molecular diagnosis of hereditary breast cancer

abstract background: many disease susceptibility genes are large and consist of many exons in which point mutations are scattered throughout. scanning each exon individually represents a tedious task which can be time consuming and expensive. there has been increasing demand for rapid and accurate methods for full scanning of unknown point mutations in large multi-exon genes. gene assembling is...

the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region

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...

Molecular imaging approaches in the diagnosis of breast cancer: A systematic review and meta-analysis

Introduction:The accuracy of positron emission tomography with computed tomography (PET/CT), positron emission mammography (PEM), and breast specific-gamma imaging (BSGI) in diagnosing breast cancer has never been systematically assessed, the present systematic review was aimed to address this issue.  Methods:PubMed, Scopus and EMBASE were searched for st...

Evaluation of Nucleostemin Gene Expression as a New Molecular Marker in Breast Tumors

Background & Aims: Nucleostemin is one of the stem cell enriched proteins which encodes a novel nucleolar GTP-binding protein found at high levels in the adult and embryonic stem (ES) cells but not in terminally differentiated cells. It is also expressed in tumor cell lines as well as in the several types of human cancers. Due to the increasing rate of breast cancer in recent years, in the pres...

Presymptomatic diagnosis of hereditary breast cancer

The molecular pathology of hereditary breast cancer.

Hereditary breast cancer arising in carriers of mutations in the BRCA1 and BRCA2 genes differs from sporadic breast cancer and from non-BRCA1/2 familial breast carcinomas. Most BRCA1 carcinomas have the basal-like phenotype and are high-grade, highly proliferating, estrogen receptor-negative and HER2-negative breast carcinomas, characterized by the expression of basal markers such as basal kera...
