Hereditary breast cancer: from molecular pathology to tailored therapies.

Cytoplasmic Her2/neu immunohistochemical staining in breast cancer; From a molecular point of view

Chromogenic in situ Hybridization Compared with Real Time Quantitative Polymerase Chain Reaction to Evaluate HER2/neu Status in Breast Cancer

Background and objective: The assessment of human epidermal growth factor receptor 2 (HER2) status has become of great importance in the diagnosis of breast cancer. The aim of this study was to investigate the diagnostic value of quantitative Polymerase Chain Reaction (qPCR) and Chromogenic In Situ Hybridization (CISH) to assess HER2 status of biopsy specimens. <...

Molecular mechanisms involved in multidrug resistance in breast cancer therapy

Breast cancer is the most prevalent cancer in women. Chemotherapy is the main strategy in the treatment of this disease especially in the advanced form of the disease. Despite the recent progress in the development of new chemotherapy, the effectiveness of these drugs has dramatically reduced due to multidrug resistance. The phenotype of multidrug resistance (MDR) can occur through different me...

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 i...

Women with hereditary breast cancer predispositions should avoid using their smartphones, tablets and laptops at night

Breast cancer is the most common malignancy among women, both in the developed and developing countries. Women with mutations in the BRCA1 and BRCA2 genes have an increased risk of breast and ovarian cancers. Recent studies show that short-wavelength visible light disturb the secretion of melatonin and causes circadian rhythm disruption. We have previously studied the health effects of exposure...
