The estrogen receptor (ER) is a ligand-activated transcription factor that mediates the effects of the steroid hormone 17 beta-estradiol, in both males and females. Since the isolation and cloning of ER, the consensus has been that only one such receptor exists. The finding of a second subtype of ER (ER beta) has caused considerable excitement amongst(More)
Ath1 is a quantitative trait locus on mouse chromosome 1 that renders C57BL/6 mice susceptible and C3H/He mice resistant to diet-induced atherosclerosis. The quantitative trait locus region encompasses 11 known genes, including Tnfsf4 (also called Ox40l or Cd134l), which encodes OX40 ligand. Here we report that mice with targeted mutations of Tnfsf4 had(More)
The universal chromophore of visual pigments in higher animals is 11-cis retinaldehyde. The final step in the biosynthetic pathway generating this compound is catalyzed by 11-cis retinol dehydrogenase, a membrane-bound enzyme abundantly expressed in the retinal pigment epithelium of the eye. In this work we demonstrate that the primary structure of human(More)
The regulation of CYP2E1 and 2B1 was studied by following mRNA levels, catalytic activities and the subcellular distribution of the apoproteins in rat liver 0, 6, 12, 24, 48 and 96 h after a single intragastric dose of acetone. No changes were observed in hepatic CYP2E1 mRNA levels at any time after acetone treatment, whereas rapid rises were observed in(More)
With the goal of better understanding the function and regulation of the different members of the VEGF family this study reports mapping of vegf, vegf-b and vegf-c mRNA expression in developing and adult mice. On embryonic day 14 (E14) there is a high expression of vegf and vegf-b, vegf-b being exceptionally high in heart and CNS. The vegf-c expression is(More)
Apoptosis in murine myeloid cell lines requires the expression of the Requiem gene, which encodes a putative zinc finger protein. We detected the protein in both cytoplasmic and nuclear subcellular fractions of murine myeloid cells and human K562 leukemia cells, which suggests that the protein might have a function distinct from a transcription factor. This(More)
We have previously identified a novel gene closely related to the vasoactive endothelial growth factor (VEGF) gene. The human VEGF related factor (VRF) gene was initially isolated using an 11q13 specific cosmid probe (D11S750). Subsequently human VRF was used to isolate the corresponding mouse gene (vrf). Here, we report the spatiotemporal expression(More)
Platelet membrane glycoprotein IIb/IIIa plays an important role in platelet aggregation. A polymorphism of the gene encoding the IIIa subunit, with the two allele forms PLA1 and PLA2, has been identified. Some, but not all, studies suggest that the PLA2 allele confers an increased risk of suffering a myocardial infarction. Conversely, a recent study(More)
We describe the isolation, characterization, and genomic structure of a gene, Phospholipase C beta 3 Neighboring gene (PNG), located on chromosome 11q13. The cDNA was isolated using a cosmid that also contains the phospholipase C beta 3 gene (PLCB3). PNG does not have any marked similarity to other known genes on the DNA level. However, analysis of(More)
We describe the isolation and expression of a murine homologue of the Phospholipase C beta3 Neighboring Gene (PNG), located in the MEN1 region on chromosome 11q13. The PNG cDNA was isolated using a human PNG cDNA clone (SOM172). Human and mouse PNG do not have any marked similarity to other known genes on the DNA level, but the predicted protein display(More)
