MRP2 encoded by ABCC2 gene is involved in the secretion of numerous drugs and endogenous substrates. Patients with Dubin-Johnson syndrome due to mutation in ABCC2 gene have elevated urinary coproporphyrin ratio (UCP I/(I + III)). Here we investigated whether this ratio could serve as a biomarker of MRP2 function. Phenotype-genotype relationships were studied in 74 healthy subjects by measuring ...
BACKGROUND Genotypes of the drug-metabolizing enzyme CYP2D6 influence plasma levels of 25% of commonly prescribed drugs. This is the first study in India to investigate the genotype-phenotype relationship of CYP2D6. AIM To study the influence of some CYP2D6 genotypes on the metabolism of its substrate dextromethorphan in healthy South Indian volunteers and to assess the contribution of the CY...
Little is known of the prevalence of Cryptosporidium and Giardia in domestic cats in Western Australia and their potential role as zoonotic reservoirs for human infection. In the present study, a total of 345 faecal samples from four different sources were screened for the presence of Cryptosporidium and Giardia by PCR and genotyped by sequence analysis. Oocyst numbers and cyst numbers for Cryp...
background:â there is a relationship between specific genotypes of helicobacter pylori caga and vaca genes and the increased risk of peptic ulcer diseases and gastric cancer. these genes also possess strong patterns of geographical differentiation. the present study aims to determine the patterns of variation of the virulence genes in iran and their association with clinical status. materials a...
BACKGROUND The interferon-free regimen of ABT-450 with ritonavir (ABT-450/r), ombitasvir, and dasabuvir with or without ribavirin has shown efficacy in inducing a sustained virologic response in a phase 2 study involving patients with hepatitis C virus (HCV) genotype 1 infection. We conducted two phase 3 trials to examine the efficacy and safety of this regimen in previously untreated patients ...
Thirty Newcastle disease virus (NDV) strains isolated from outbreaks in China during 1996 to 2005 were characterized pathotypically and genotypically. All strains except one were velogenic. An analysis of the variable region (nucleotides 47 to 420) of the F gene indicated that 6 isolates belonged to genotype II, 3 to genotype III, 1 (isolated from a pigeon) to genotype VI, and 20 to genotype VI...
This study defined the genetic epidemiology of dengue viruses (DENV) in two pivotal phase III trials of the tetravalent dengue vaccine, CYD-TDV, and thereby enabled virus genotype-specific estimates of vaccine efficacy (VE). Envelope gene sequences (n = 661) from 11 DENV genotypes in 10 endemic countries provided a contemporaneous global snapshot of DENV population genetics and revealed high am...
PURPOSE The TP53 tumor suppressor is frequently mutated in colon cancer, but the influence of such mutations on survival remains controversial. We investigated whether mutations in the DNA-binding domain of TP53 are associated with survival in stage III colon cancer. EXPERIMENTAL DESIGN The impact of TP53 genotype was prospectively evaluated in Cancer and Leukemia Group B 89803, a trial that ...
Sequence analysis at the 35-fold-repetitive B1 locus identified three restriction sites capable of discriminating type I (mouse-virulent) from type II or III (mouse-avirulent) strains of Toxoplasma gondii. B1 PCR-restriction fragment length polymorphism analysis of 8 type I, 17 type II, and 8 type III strains confirms the specificity of the assay. It should now be possible to ask whether strain...
