'Human embryonic stem (hES) cells as a renewable cell source have great prospective applications in both developmental biology research and regenerative medicine. To realize these potentials, the development of effective and safe genetic manipulation methods in hES cells is an obvious demand. We report here that baculoviral vectors were able ... More
Cloning and characterization of PDE7B, a cAMP-specific phosphodiesterase.

PubMed ID10618442
A member of the phosphodiesterase (PDE)7 family with high affinity and specificity for cAMP has been identified. Based on sequence homologies, we designate this PDE as PDE7B. The full-length cDNA of PDE7B is 2399 bp, and its ORF sequence predicts a protein of 446 amino acids with a molecular mass ... More
The orexin OX1 receptor regulates Ca2+ entry via diacylglycerol-activated channels in differentiated neuroblastoma cells.
We studied the cellular response to orexin type 1 receptor (OX1R) stimulation in differentiated IMR-32 neuroblastoma cells. In vitro differentiation of IMR-32 cells with 5-bromo-2'-deoxyuridine leads to a neuronal phenotype with long neurite extensions and an upregulation of mainly N-type voltage-gated calcium channels. Transduction of differentiated IMR-32 cells with baculovirus ... More

RAD51B and RAD51C are two of five known paralogs of the human RAD51 protein that are thought to function in both homologous recombination and DNA double-strand break repair. This work describes the in vitro and in vivo identification of the RAD51B/RAD51C heterocomplex. The RAD51B/RAD51C heterocomplex was isolated and purified by ... More
Gene characterized for membrane desaturase that produces (E)-11 isomers of mono- and diunsaturated fatty acids.
Moth species have evolved integral membrane desaturases that exhibit a wide diversity in substrate specificity, as well as in regiospecificity and stereospecificity of the unsaturated products. We report here the cloning and expression of a single desaturase from the sex pheromone gland of the light brown apple moth, Epiphyas postvittana, ... More
Reconstitution of ATP-dependent leukotriene C4 transport by Co-expression of both half-molecules of human multidrug resistance protein in insect cells.

JournalJ Biol Chem
PubMed ID8910374
Multidrug resistance protein (MRP) confers a multidrug resistance phenotype similar to that associated with overexpression of P-glycoprotein. Unlike P-glycoprotein, MRP has also been shown to be a primary active ATP-dependent transporter of conjugated organic anions. The mechanism(s) by which MRP transports these compounds and increases resistance to natural product drugs ... More
