β-Thalassemia/HbE disease is clinically variable. In searching for genetic factors modifying the disease severity, patients were selected based on their disease severities, and a genome-wide association study (GWAS) was performed. Genotyping was conducted with the Illumina Human 610-Quad BeadChips array using DNAs from 618 Thai β0-thalassemia/HbE patients(More)
Erythropoiesis in β0-thalassaemia/Hb E patients, the most common variant form of β-thalassaemia in Southeast Asia, is characterized by accelerated differentiation and over-expansion of erythroid precursor cells. The mechanism driving this accelerated expansion and differentiation remain unknown. To address this issue a proteomic analysis was undertaken to(More)
Repair of beta-globin pre-mRNA rendered defective by a thalassemia-causing splicing mutation, IVS2-654, in intron 2 of the human beta-globin gene was accomplished in vivo in a mouse model of IVS2-654 thalassemia. This was effected by a systemically delivered splice-switching oligonucleotide (SSO), a morpholino oligomer conjugated to an arginine-rich(More)
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT UGT1A6 has been proposed as the predominant isoform responsible for the glucuronidation of deferiprone. UGT1A6*2 allele has been associated with the altered enzyme activity. WHAT THIS STUDY ADDS There is no statistically significant effect of UGT1A6 genotype on the single-dose pharmacokinetics of deferiprone in(More)
In Vietnam, the carrier rate for beta-thalassemia varies from 1.5% to 25% depending on the ethnic groups of the population. The molecular basis of beta-thalassemia in South Vietnam was studied in 50 unrelated beta-thalassemia patients. Of these, 31 had beta-thalassemia/Hb E, 18 were homozygous for beta-thalassemia, and 1 carried the beta-thalassemia trait.(More)
BACKGROUND Cells respond to stress stimuli through a number of response pathways, of which one of the most important and well characterized is the unfolded protein response. Despite a large body of work which suggests that stress in erythroblasts may play a pivotal role in the pathogenesis of beta-thalassemia/Hb E disease, this pathway remains(More)
Beta-thalassaemia is one of the most common inherited anaemias, arising from a partial or complete loss of beta-globin chain synthesis. In severe cases, marked bone marrow erythroid hyperplasia, believed to result from erythropoietin (EPO)-mediated feedback from the anaemic condition is common, however, as yet, no study has investigated EPO-mediated signal(More)
There is considerable ethno-linguistic and genetic variation among human populations in Asia, although tracing the origins of this diversity is complicated by migration events. Thailand is at the center of Mainland Southeast Asia (MSEA), a region within Asia that has not been extensively studied. Genetic substructure may exist in the Thai population, since(More)
A β-thalassaemia mutation occurring from insertion of a duplicated 22-bp intron/exon junction of the β-globin gene has been characterised. The repeated 22-bp insertion causes duplication of a 3′ splice site at IVSI/exon 2 junction. Reverse transcription–polymerase chain reaction showed that the proximal 3′ splice site present in the duplicated gene is used,(More)
OBJECTIVE This study investigated anti-inflammatory and antioxidant activities of an ethanol extract from Thai red curry paste. METHODS The RAW264.7 murine macrophage cell line was incubated with the extract (65-260 μg/mL) with or without lipopolysaccharide. The anti-inflammatory activities of the extract were examined by measuring inducible nitric oxide(More)
