jak2 is a tyrosine kinase that plays an important role in the signaling pathways of many hematopoietic growth factor receptors. a single acquired point mutation – v617f – in jak2 occurs in the great majority of patients with polycythemia vera (pv) and approximately half of the patients with idiopathic myelofibrosis (imf) or essential thrombocythemia (et). in contrast, the jak2-v617f mutation is...
Background & Aims: Genetic mutation, 1691G> A common polymorphism in a gene that is inherited coagulation Factor 5 is associated with increased risk of thrombosis. This mutation in different populations can develop in the prognosis of thrombotic disorders, cardiovascular disorders recurrent miscarriage and other thrombotic factors are useful. Study using appropriate strategies such as review o...
MeduIIary thyroid carcinoma (MTC) occurs both sporadically and in the autosomal dominantly inherited multiple endocrine neoplasia (MEN) type 2 syndromes. The distinction between true sporadic MTC and a new mutation familial case is important for future clinical management of both the patient and family. The susceptibility gene for hereditary MTC is the RET proto-oncogene. DNA analysis for g...
Background and Objective: BRAF mutations were studied in various populations for prostate carcinoma (PC); however, mutations in BRAF gene are unusual compared to KRAS. Oncogenic activating of BRAF mutations were studied lately in almost 0%-10% of prostate cancer cases. Methods: In this retrospective study, we gathered 100 formalin-fixed ...
Background and Objective: Mutations in GJB2 gene is the most common cause of autosomal recessive non-syndromic hearing loss in many populations. The aim of this study was to determine the frequency of 35delG, 167delT, M34T, 235delC mutations in West Azarbaijan population. Materials and Methods: 129 patients from 96 families were studied. Mutations were detected using ASO-PCR and PCR-RFLP method...
Background: Congenital hearing loss due to different genetic and environmental causes affects 1 in 1000 newborns. Mutations in the GJB2 (Gap Junction Beta-2) gene encoding the gap junction protein connexin 26 have been established as the main cause of autosomal recessive non-syndromic hearing loss. Materials and methods: The aim of this study was to study the frequency of GJB2 Mutations in Lor...
Background and purpose: Chemokines and their receptors are expressed in different types of malignancies. CC chemokines MIP-1a (CCL3), MIP-1b (CCL4) and RANTES (CCL5) is believed to be anti-tumor and also aid to the metastasis in tumor microenvironment. CCR2 and CCR5 are special G-protein receptors for these chemokines. Due to the important role of CCR5 chemokine receptor in tumor biology, this ...
Introduction: P53 is a tumor suppressor protein with numerous missense mutations identified in its gene. These mutations are observed in a vast number of cancers. R213G is one of them which has a role in metastatic lung cancers. In this research, R213G was studied in comparison with the wild type via molecular dynamics simulation. Method: For the three-dimensional structure of the wild-type P53...

objective(s): breast cancer is the most common cancer in women. every year, one million new cases are reported worldwide, representing 18% of the total number of cancer in women. hereditary brca1 and brca2 mutations account for about 60% of inherited breast cancer and are the only known causes of hereditary breast cancer syndrome. the aim of this study was to determine the frequency of brca2 (e...
