The protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene, which encodes an intracellular lymphoid-specific phosphatase, is considered an important regulator of T-cell activation. We investigated a possible association between the PTPN22 C1858T (R620W) polymorphism and pulmonary tuberculosis in an Iranian population. Single nucleotide polymorphisms of PTPN22 C1858T (rs2476601) we...

BACKGROUND Migraine is a common neurological disorder with a significant genetic component. Less information is known about the contribution of minor genetic variations, such as single nucleotide polymorphism (SNP) on the migraine process. In the present study, we aim to investigate the role of CACNA1A gene polymorphism on severity and related factors in family positive migraine patients. MAT...

Several single nucleotide polymorphisms (SNPs) of the transforming growth factor-beta1 gene (TGFB1) have been reported. Determination of TGFB1 SNPs allele frequencies in different ethnic groups is useful for both population genetic analyses and association studies with immunological diseases. In this study, five SNPs of TGFB1 were determined in 325 individuals from a normal southern Iranian pop...

Acute lymphoblastic leukemia (ALL) is a malignant transformation and proliferation of lymphoid progenitor cells in bone marrow and blood, which is mainly found in children. Thiopurine methyltransferase (TPMT) is a thiopurine drug metabolizer enzyme that is prescribed for the treatment of ALL. Several single nucleotide polymorphisms in the TPMT gene have been reported to be associated with the d...

BACKGROUND Accurate identification of sheep nematodes is a critical point in epidemiological studies and monitoring of drug resistance in flocks. However, due to a close morphological similarity between the eggs and larval stages of many of these nematodes, such identification is not a trivial task. There are a number of studies showing that molecular targets in ribosomal DNA (Internal transcri...

leptin (lep), the expression product of the obese gene produced primarily in the adipose tissue, is related to feed intake, growth and lipid metabolism. the aim of this study was to study the possible association between polymorphism of the lep gene with growth and carcass traits among three iranian sheep breeds of the shal, zandi and zel varieties. a total of 180 purebred animals of the shal, ...

AIMS The KCNJ11 gene has a strong effect on glucose-stimulated insulin secretion. Common polymorphism KCNJ11 E23K has been reported to be associated with type 2 diabetes in various European-descent populations. However, there were inconsistent results in previous studies in Asian populations, and no study has been carried out in the Iranian population. We examined the contribution of KCNJ11 E23...

PURPOSE IL-10 suppresses several activities of the immune response by inhibition of Th1 and Th2 cells. METHODS We studied 110 Iranian patients with clinically definite multiple sclerosis (MS) and 100 ethnic and age matched controls. Three single-nucleotide polymorphisms in the proximal region of IL-10 promoter gene (-1082/-819/-592) were analysed by amplification refractory mutation system (A...

Abstract Background Interleukin (IL)-10 is one of the key interleukins in immune system. It plays an anti-inflammatory role body by inhibition synthesis pro-inflammatory cytokines and reducing expression major histocompatibility complex II molecules. The single-nucleotide polymorphism gene this interleukin affects its level. Thus, study was conducted to investigate IL-10 at position -1082A/G Az...
