Human CEGP-2 cDNA

This invention is directed to cloning and characterization of BVES (blood vessel/epicardial substance), a cDNA expressed in developing and adult heart and skeletal muscle cells in chick, mouse and human. Also provided are applications of BVES as a marker for cardiovascular or skeletal muscle diseases.

Model Uses PA1-1 Inhibitors

A method of testing a candidate composition for PAI-1 inhibition activity is disclosed. The method includes the steps of obtaining a transgenic non-human warm blooded vertebrate animal having incorporated into its genome a PAI-1 gene encoding a biologically active PAI-1 polypeptide, the PAI-1 gene being present in the genome in a copy number effective to confer over-expression in the transgenic non-human animal of the PAI-1 polypeptide; administering the composition to the transgenic non-human animal; and observing the transgenic non-human animal for determination of a change in the transgenic non-human animal indicative of inhibition of the activity of PAI-1. A transgenic non-human animal useful in such a method is also disclosed, as is a PAI-1 transgene construct encoding a biologically active PAI-1 polypeptide useful for preparing the transgenic non-human animal.

Cytochrome P450 Epoxygenase Induces Hypertension

The invention provides an isolated nucleic acid encoding the rat P450 2C11 arachidonic acid epoxygenase, or a human homologue thereof, having a mutation associated with salt induced hypertension. Also provided is an isolated cell line expressing the epoxygenase encoded by the mutated nucleic acid, and a non-human transgenic animal having a germ line insertion of the mutated nucleic acid. Also provided is a method of screening a compound for efficacy in treating salt induced hypertension comprising administering the compound to such a non-human transgenic animal, and detecting an improvement in the animal's hypertension. The invention also provides a method of screening a human subject for a genetic predisposition to salt induced hypertension comprising detecting a mutation in a human homologue of a rat P450 2C11 arachidonic acid epoxygenase gene which affects normal epoxygenase activity. Also provided is a method of treating salt induced hypertension in a human subject associated with a genetic mutation in a human homologue of the rat P450 2C11 arachidonic acid epoxygenase gene, comprising administering to the subject a functional metabolite, or analogue thereof, produced by the human homologue of the rat P450 2C11 arachidonic acid epoxygenase. Also provided is an isolated mutated rat P450 2C11 arachidonic acid epoxygenase, or a human homologue thereof, having a mutation associated with salt induced hypertension.

Synthesis of Thallium-sensitive Fluorescent Dyes to Monitor Potassium Channel or Potassium-Dependent Transporter Activity

This technology describes a strategy for the synthesis of novel fluorescent thallium indicator dyes, which are useful for high throughput testing of potassium-dependent ion channel or transporter activity.
