Background: P-glycoprotein, the product of MDR1 (multi drug resistance) gene, is a trans membrane efflux pump, transferring drugs and toxins from intracellular to extracellular domains. It acts as a protective barrier to keep toxins out of the body by excreting them into the bile, urine and intestinal lumen. In the human gastrointestinal tract, P-glycoprotein is found in high concentrations on ...
conclusions: we determined a significant higher frequency of protein s deficiency in patients with rpl compared with controls. but the frequency of protein c deficiency and the frequency of two common thrombophilic mutations (factor v leiden and prothrombin g20210a), were not significantly different between patients with recurrent miscarriage and healthy women. results: the mean functional acti...
Background: Breast cancer is one of the most common cancer of women in the world. Although different genetic alteration has been reported in this malignancy, but P 53 gene mutations has more frequency. P 53 gene is one of the most important suppressor genes and it play a central role in breast cancer and detecting of mutations in this gene would be very helpful in understanding of genetic m...
Background & Objective: Cytokines are immune system factors known to play a key role in both HCV clearance and the development of infection the impact of host genetic factors on the clinical outcome of HCV infection has not been elucidated. On the other hand, the impact of Genetic changes like Single nucleotide polymorphisms on expression rate and function of Cytokine is under study. The aim ...
a total of 3204 abo and rh blood groups were investigated in larestan and lamerd populations, in fars province, in iran. the frequency of the a gene ranged from 16.54% to 21.96, the b gene from 15.85 to 27.77% and that of the d gene from 21.49 to 33.01% ; compared with the gene frequencies of 20.97% for the b and 28.50% for the d in the general population. it seemed that the two populations stu...
Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) can cause serious and life-threatening hospital- and community-acquired infections. Colonized and infected patients represent the most important reservoir of MRSA in health care facilities. Therefore, in this study, MRSA isolates collected from Shohada Hospital in Tabriz were evaluated for the frequency of mecA gene and their anti...
Background and Objective: B-thalassemia is an autosomal recessive disease characterized by reduction or complete absence of b-globin gene expression. It has been estimated that more than 2,000,000 carriers as well as 20,000 patients affected with b-thalassemia are living in Iran, a country with more than 70 million population and great ethnic diversity. In this study we aimed to find out the b-...
Introduction: Systemic lupus erythematosus (SLE) is a chronic systemic inflammatory autoimmune disease characterized by a breakdown of self-tolerance. Transforming growth factor-β1 is a cytokine produced by both immune and non immune cells, and it has a wide operating range. human TGF-β1 gene is located on chromosome 19q13 . The aim of this study was investigating the TGF-β1 Gene...
ABSTRACT Background and Objectives: Mycobacterium tuberculosis is the causative agent of pulmonary tuberculosis, a main public health problem that results in 1.5 million deaths annually. A number of epidemiological studies suggested that host genetic factors could play a main role in susceptibility to tuberculosis infection. SP110 is an i...
