Both hereditary and sporadic breast cancers may develop through dysregulation of self-renewal pathways of normal mammary stem cells. Networks of proto-oncogenes and tumor suppressors that control cancer cell proliferation also regulate stem cell self-renewal and possibly stem cell aging. Breast cancer susceptibility gene (BRCA1) is a nuclear phosphoprotein(More)
Breast cancer is the most common malignancy among females in the world. In Iran, age and family history are the major risk factors for the development of this disease. Mutations of BRCA1 and BRCA2 genes are associated with a greatly increased risk for familial breast cancer. The frequency of BRCA mutations was identified in familial breast cancers (FBCs)(More)
Breast cancer is a multistep disease and infection with a DNA virus could play a role in one or more of the steps in this pathogenic process. High-risk human papillomaviruses (HPVs) are the causative agents of several cancers. In this study, we investigated HPV genotypes associated with breast cancer and its relationship with BRCA mutation for the detection(More)
Human papillomavirus (HPV), a major pathogen of human cervical cancer, contains a full-length L1 gene encoding its surface capsid protein. One group of potential vaccine candidates against this virus in Iranian patients is based on surface protein components such as HPV31 L1 protein that can make virus-like particles (VLPs). The high immunity response(More)
Type II diabetes mellitus (T2DM) is the prevalent type of diabetes, including 90% of the cases world-wide. Helicobacter pylori plays a pathogenic role in the development of T2DM. The host genetic factors have a significant impact on the clinical outcome and anatomical distribution of H. pylori infection and polymorphisms in several genes such as tumor(More)
Hemophilia A is an X-linked disorder affecting 1 in 10,000 males. The disease is caused by a defect or mutation of factor 8 or 9. Human factor 8 gene (hFVIII) is a relatively large gene consisting of 26 exons and approximately 2,351 amino acids with a length of 9 Kb mRNA. Expression of hFVIII in mammalian milk is becoming a widespread strategy for(More)
Erythromycin is a macrolide antibiotic with broad-spectrum activity against gram-positive bacteria that stops protein synthesis by binding to 50s ribosomal subunit. Classical and recombinant strain improvement, such as application of ultraviolet (UV) mutagenesis and selection of overproduction mutant, is the most important and convenient method in(More)
Breast cancer (BC) is the leading cause of death among Iranian women. Development of BC is a multistep process, arising from genetic changes such as methylenetetrahydrofolate reductase (MTHFR) polymorphism and infection with human papillomavirus (HPV). In this study, we investigated HPV genotypes associated with BCs and its relation with MTHFR C677T(More)
