Dlk1 and Gtl2 are reciprocally imprinted genes located 80 kb apart on mouse chromosome 12. Similarities between this domain and that of the well characterized Igf2-H19 locus have been previously noted. Comparative genomic and epigenetic analysis of these two domains might help identify allele-specific epigenetic regulatory elements and common features(More)
In a previous 52-wk trial, treatment with alglucosidase alpha markedly improved cardiomyopathy, ventilatory function, and overall survival among 18 children <7 mo old with infantile-onset Pompe disease. Sixteen of the 18 patients enrolled in an extension study, where they continued to receive alglucosidase alpha at either 20 mg/kg biweekly (n = 8) or 40(More)
Many genes subject to genomic imprinting function in a number of endocrine/paracrine pathways that are important for normal mammalian development. Here, we show that an endocrine/paracrine pathway involving thyroid hormone metabolism is also regulated by imprinting. Thyroid hormone action depends on thyroid hormone receptors and their predominant ligand,(More)
The imprinted Dlk1-Dio3 region on mouse chromosome 12 contains six imprinted genes and a number of maternally expressed snoRNAs and miRNAs. Here we present a high-resolution sequence analysis of the 1.1-Mb segment telomeric to Gtl2 in mouse and a homology comparison to the human. Ppp2r5c and Dnchc1 at the telomeric end of the analyzed sequence are(More)
A subset of mammalian genes is controlled by genomic imprinting. This process causes a gene to be expressed from only one chromosome homologue depending on whether it originally came from the egg or the sperm. Parental origin-specific gene regulation is controlled by epigenetic modifications to DNA and chromatin. Genomic imprinting is therefore a useful(More)
AIM To evaluate the effects of an Al(3+)- and Mg(2+)-containing antacid, ferrous sulfate, and calcium carbonate on the absorption of nemonoxacin in healthy humans. METHODS Two single-dose, open-label, randomized, crossover studies were conducted in 24 healthy male Chinese volunteers (12 per study). In Study 1, the subjects orally received nemonoxacin (500(More)
Carbohydrate deficient glycoprotein syndromes (CDG) are inherited multisystem disorders characterized by the abnormal glycosylation of a number of serum glycoproteins. CDG-Ia results from deficiency of phosphomannomutase that catalyzes the conversion of mannose-6-phosphate to mannose-1-phosphate in the cytosol. We report a case of CDG-Ia in an 11-month-old(More)
