background: breast cancer is the first leading cause of cancer-related death in women. pesticides which are excessively used in northern iran are one of the most important risk factors for breast cancer incidence. the cytochrome p450 1a1 (cyp1a1) is a key enzyme in xenobiotics metabolism and snps of its coding gene has been verified to be important in cancer susceptibility. the aim of this stud...

introduction: using addictive drugs can change the amount of neurotransmitters, especially dopamine and glutamate. glutamate has been known to trigger the relapse and tendency toward addictive drugs. the glutamate receptor ionotropic nmda type subunit 1 (grin1) contains the single- nucleotide polymorphism c1001g (rs11146020) and encodes n-methyl-d-aspartic acid (ndma) receptor subunit 1 (nr1). ...

background three single nucleotide polymorphisms (snps) near interleukin-28b (il-28b) gene were shown to be highly associated with treatment response (svr) in patients with chronic hepatitis c virus (hcv) infection. there is limited data about the role of single and combined il-28b polymorphisms in hcv-infected polish population. objectives this study's aim was to determine predictability of th...

conclusions our results showed for the first time that lyplal1 gene is not associated with a risk of nafld development in the chinese han population. the variant carriers of overall subjects significantly increased weight, bmi and ldl. patients and methods lyplal1 rs12137855 gene was genotyped in 184 patients with nafld and 114 healthy controls using sequencing and polymerase chain reaction ana...

conclusions trim22 gene ring domain -364t/c polymorphism is associated with chronic hbv infection in chinese han population. results 243 (31.76%) of 765 chinese han patients showed genetic variation in the trim22 gene. trim22 snps were mainly in ring area -364t/c site, accounting for 98.35% of the population. there were no significant differences (p > 0.05) in the ring domain -364t/c snp and al...

matrix metalloproteinases (mmps) play an important role in gastric cancer (gc). accumulated evidence suggests that functional mmp-1 and mmp-7 gene polymorphisms are associated with several tumors. the aim of this study was to investigate two single nucleotide polymorphisms, mmp-1 -1607 1g/2g and mmp-7 -181 a/g, and their potential relationship with gc. we examined 246 gc  patients and 252 age-a...

abstract   background: the disrupted-in-schizophrenia 1 (disc1) gene, on the chromosome position 1q42, was initially identified at the breakpoint of a balanced translocation, t(1,11)(q42.1q14.3), which segregated with major mental disorders in a large scottish family.   methods: our samples included 200 unrelated patients diagnosed with schizophrenia on the basis of dsm-iv criteria and 200 norm...

results no significant correlation was seen in rs3743527 and rs129081 polymorphism’s allelic and genotypic frequencies between the patient group and control individuals (p value > 0.05). the average frequencies of rs129081 g and c alleles was 40 (58%) and 29 (42%), respectively. in our sample the average frequencies of rs3743527 c and t alleles, were 41 (61%) and 28 (39%), respectively. the res...

prions are unprecedented infectious pathogens that cause a group of invariably fatal neurodegenerative disease by an entirely novel mechanism. the conformational change in prion proteins results in a change from a predominantly α-helical protein to a β-sheet form, which causes scrapie in sheep and goat. the present study was carried out to identify polymorphisms of the prion protein gene (prp) ...
