The imprinted mouse gene Gnas produces the G protein alpha-subunit G(S)alpha and several other gene products by using alternative promoters and first exons. G(S)alpha is maternally expressed in some tissues and biallelically expressed in most other tissues, while the gene products NESP55 and XLalphas are maternally and paternally expressed, respectively. We investigated the mechanisms of Gnas i...

Growth differentiation factor 9 (GDF9) belong to the superfamily of transforming growth factor β that is highly expressed in growing ovarian follicles of oocyte, and it has been strongly related to fecundity traits in sheep. Therefore, the GDF9 gene could serve as a genetic marker for improvement of reproductive performance in sheep. Therefore, the aim of this study was to invest...

Twelve single nucleotide polymorphisms (SNPs) in the human CES2 gene, which encodes a carboxylesterase, hCE-2 [human carboxylesterase 2 (EC 3.1.1.1)], have been reported in the Japanese. In this report, we have examined functional alterations of three SNPs, a nonsynonymous SNP (100C>T, R34W), an SNP at the splice acceptor site in intron 8 (IVS8-2A>G), and one newly discovered nonsynonymous SNP ...

Glycogen storage disease type II is a lysosomal storage disorder due to mutations of the GAA gene, which causes lysosomal alpha-glucosidase deficiency. Clinically, glycogen storage disease type II has been classified in infantile and late-onset forms. Most late-onset patients share the leaky splicing mutation c.-32-13T>G. To date, the mechanism by which the c.-32-13T>G mutation affects the GAA ...

We characterized the nearly complete coding sequence of the pig 2,4-dienoyl CoA reductase 1 (DECR1) gene, which encodes an enzyme involved in the beta-oxidation of polyunsaturated fatty enoyl-CoA esters and maps on a linoleic QTL located on Chromosome 4. Sequencing of a 937-bp fragment encompassing exons 2 and 10 revealed the existence of two missense SNP at exon 2 (C181 --> G181) and exon 5 (C...

Although the sympathetic nervous system (SNS) plays a major role in mediating the peripheral stress response, due consideration is not usually given to the effects of prolonged stress on the SNS. The present study examined changes in neurotransmission in the SNS after exposure of mice (BALB/c) to stressful housing conditions. Focal extracellular recording of excitatory junction currents (EJCs) ...

Asthma is a disease marked by inflammation of airways with an increasing incidence rate worldwide especially among Asian population. Spleen tyrosine kinase (Syk) is known to be involved in regulation of such inflammation response and thereby rendering its inevitable importance among asthma patients. DNA extraction followed by PCR and sequencing was performed for genomic analysis, mRNA analysis ...

The heterogeneous nuclear ribonucleoprotein H (hnRNP) family of proteins has been shown to activate exon inclusion by binding intronic G triplets. Much less is known, however, about how hnRNP H and hnRNP F silence exons. In this study, we identify hnRNP H and hnRNP F proteins as being novel silencers of fibroblast growth factor receptor 2 exon IIIc. In cells that normally include this exon, we ...
