Summary for Patent: 7,169,612
Title:Use of EDG2 receptor in an animal model of heart failure
Abstract: Mammals and myocardial mammal cells transformed with G protein coupled receptor EDG2 are presented for use in an animal model for heart failure.
Inventor(s): Kostenis; Evi (Grebenau, DE), Wohlfart; Paulus (Bensheim, DE), Huber; Jochen (Maxdorf, DE), Rosport; Kai (Munich, DE), Bueltmann; Andreas (Munich, DE), Baumgartner; Christine (Munich, DE), Muench; Gotz (Munich, DE), Ungerer; Martin (Munich, DE)
Assignee: Sanofi-Aventis Deutschland GmbH (Frankfurt, DE)
Application Number:10/706,763
Patent Claims:1. A myocardial cell of a non-human mammal, wherein the myocardial cell contains an adenoviral vector sequence for simultaneous expression of G protein coupled receptor EDG002 and a cellular marker.

2. The myocardial cell of claim 1, wherein the cellular marker is a fluorescent protein.

3. The myocardial cell of claim 2, wherein the cellular marker is Green Fluorescent Protein.

4. The myocardial cell of claim 2, wherein the adenoviral vector sequence comprises of a recombinant E1/E3 deficient adenovirus which expresses the G protein coupled receptor EDG2 and the fluorescent protein under control of two independent promoters.

5. The myocardial cell of claim 4 wherein the two independent Promoters are two CMV promoters.

6. A method of producing of a myocardial cell according to claim 1, comprising: a. removing the heart of a non-human mammal, b. perfusing the removed heart, digesting the removed heart whit collagenase, and isolating cardiomyocytes, and c infecting the isolated cardiomyocytes with an adenoviral vector comprising a recombinant E1/E3 deficient adenovirus which expresses the G protein coupled receptor EDG2 and a cellular marker under control of two independent promoters.

7. The method of claim 6, wherein the cellular marker is a fluorescent protein.
