Genetic involvement in type 1 autoimmune hepatitis (AIH) is indicated by a marked female preponderance and strong, well-established, human leukocyte antigen (HLA) associations. These associations, however, are not universal and a number of genes outside the major histocompatibility complex may also play a role in susceptibility to type 1 AIH. Prime(More)
BACKGROUND The genetic basis of susceptibility to hepatocellular carcinoma (HCC) is poorly understood. Genomic DNA was available from 98 patients with HCC, 77 familial controls, 97 controls from Hong Kong and 96 Northern European controls (NECs). METHODS Polymorphisms of interleukin (IL)-1beta; IL-1 receptor antagonist (IL-1RN); IL-10 promoter (positions(More)
BACKGROUND/AIMS Though there is a consensus that the HLA DQB1*0301 allele is important in untreated HCV clearance, this association is not universal and a number of genes outside the major histocompatibility complex may also play a role in host responses to HCV infection. Prime candidates, at present, are the genes encoding pro-inflammatory and(More)
BACKGROUND/AIMS Extrahepatic biliary atresia remains one of the major hepatic causes of death in early childhood. Though a number of hypotheses have been developed to account for this disease, its aetiopathogenesis is poorly understood. One possibility is that this is an immune mediated disease which occurs following either toxic or infectious insult in a(More)
BACKGROUND & AIMS Polymorphisms that control cytokine production can affect immunoregulation. The frequency and consequences of these polymorphisms in type 1 autoimmune hepatitis were determined. METHODS DNA samples from 155 patients and 102 ethnically similar normal individuals were assessed by polymerase chain reaction for polymorphisms of 4 different(More)
AIMS/BACKGROUND Recent evidence suggests that spontaneous clearance of hepatitis C virus (HCV) may be associated with the HLA DQB1*0301 allele but there is still some debate over the role of other alleles and HLA haplotypes in HCV infection. As this may best be resolved by studying genetically different populations, we have investigated HLA class II-encoded(More)
BACKGROUND/AIMS HFE-related haemochromatosis is a common disorder of iron metabolism. Most affected individuals are homozygous for the C282Y mutation of HFE. Some are compound heterozygotes for C282Y/H63D. A small proportion have neither of these genotypes. We have investigated the phenotype of compound heterozygotes for C282Y and another missense mutation(More)
BACKGROUND & AIMS Recent studies suggest that major histocompatibility complex-encoded susceptibility to primary sclerosing cholangitis (PSC) maps to the HLA B-TNFA region on chromosome 6p21.3. METHODS The present study uses a standard polymerase chain reaction protocol to investigate the 16 common alleles of the MICA locus as candidates in 2 patient(More)
A series of 21 novel 2-[(aminocarbonyl)amino]-5-acetylenyl-3-thiophenecarboxamides were synthesized and evaluated for the inhibition of IKK-2. In spite of their often modest activity on the enzyme, six selected analogs showed significant inhibition of the production of inflammatory cytokine IL-8 in IL-1beta stimulated rheumatoid arthritis-derived synovial(More)
Evaluation of a series of MetAP inhibitors in an in vitro enzyme activity assay led to the first identification of potent molecules that show significant growth inhibition against Burkholderia pseudomallei. Nitroxoline analogs show excellent inhibition potency in the BpMetAP1 enzyme activity assay with the lowest IC50 of 30 nM, and inhibit the growth of B.(More)
