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)
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)
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)
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)
