Introduction: Nicotine is the psychoactive substance responsible for establishing and maintaining smoking dependence. CYP2A6 is the primary enzyme that inactivates nicotine to cotinine .Genetic variation in CYP2A6 accounts for some of the inter-individual variability in nicotine metabolism and has been indicated to influence smoking behavior and dependence. Therefore, the aim of this study was ...
the human leukocyte antigen (hla)-g molecule is expressed in cytotrophoblast cells, adult thymic epithelial cells, erythroblasts, pancreatic islets and mesenchymal stem cells. although, hla-g expression in allotransplanted patients is correlated with a better allograft acceptance, it is associated with an advanced grade of the tumor in cancer. in addition to the role on the immune system, hla-...
background: the study aimed to examine the association between human leukocyte antigen (hla) class ii allele frequencies and breast cancer in iranian women. methods: a total of 100 patients with pathologically proven breast cancer who referred to cancer institute were randomly selected and compared with a group of age matched healthy blood donors (n = 80). hla class ii alleles were determined b...
high molecular weight (hmw) subunits of wheat glutenin are generally considered as playing a key role in gluten formation and structure, as well as to be closely related to wheat quality. the endosperm storage proteins of 80 synthetic lines and wheat cultivars (triticum aestivum) were fractionated through sodium dodecyl sulfate polyacrylamide gel electrophoresis to determine their high-molecula...
selective iga deficiency (igad) (serum iga concentration of pcr was used to type hla b, dr, and dq alleles in 29 iranian individuals with igad and 299 swedish individuals with igad. the results indicate a strong association with the hla b14, dr1 alleles in iranian subjects and hla b8, b12, b13, b14, b40, dr1, dr3, dr7, dq2 and dq5 alleles in swedish subjects. differences in hla association of i...
NTRAGENIC complementation occurs when a full or partial restoration of 'nonmutant phenotype results from the association of two different mutant alleles in a heterozygote, heterocaryon, or heterogenote. It has been demonstrated for a number of gene loci in a variety of microorganisms which include fungi. (FINCHAM and PATEMAN 1957; GILES, PARTRIDGE and NELSON 1957; CATCHESIDE and OVERTON 1958), ...
Spinocerebellar ataxia 7 (SCA7) is the eighth neurodegenerative disorder caused by a translated CAG repeat expansion. Normal SCA7 alleles carry from four to 35 CAG repeats, whereas pathological alleles carry from 37 to approximately 200. Intermediate alleles (IAs), with 28-35 repeats in the SCA7 gene are exceedingly rare in the general population and are not associated with the SCA7 phenotype, ...
Objective: This study aimed to investigate the association between HLA alleles and visceral leishmaniasis (VL) in a sample of Iraqi patients. Methods: A total of 30 patients were studied, in addition to 20 age, gender and ethnicity matched controls. All subjects were genotyped by polymerase chain reaction-sequence specific primers (PCR-SSP) method. Results: For HLA-class I region (A and B loci)...
The risks of anal and vulvar cancer are strongly related to cigarette smoking. Smokers are exposed to a substantial quantity of tobacco-specific nitrosamines, including 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). NNK is present in the mucus of the female genital tract. The enzyme debrisoquine 4-hydroxylase (CYP2D6) activates NNK and is present in foreskin kerotinocytes and cervical ep...
background and objective: the outcome of hepatitis b virus (hbv) infection may be influenced by host factors like human leukocyte antigen (hla). we have investigated hla-a and drb1 alleles in patients with persistent hepatitis b infection compared to subjects who had spontaneously recovered from hbv infection. to complete the findings of this study we performed another survey in certain hla all...
