Title:
NON-HUMAN TRANSGENIC ANIMALS DEFICIENT IN GAS6 FUNCTION AND THEIR USE
Document Type and Number:
WIPO Patent Application WO/2000/076309
Kind Code:
A2
Abstract:
It has been shown that Gas6 deficient endothelial cells are resistant to activation by endotoxin and TNF-$g(a) in vitro and in vivo and that leukocytes did not or much less extravasate in Gas6 deficient mice. The present invention also relates to the manufacture of a medicament for the treatment of endothelial dysfunction. The present invention further relates to the use of an inhibitor of the Gas6 function and/or an inhibitor of a Gas6 receptor for the manufacture of said medicament.

Claims:
Claims
1. Nonhuman transgenic animal deficient in Gas6 function.
2. Nonhuman transgenic animal according to claim 1 in which said animal is Gas6/.
3. Nonhuman transgenic animal according to claim 1 or 2 in which said animal is a mouse.
4. Use of an animal according to claim 13 to study the role of Gas6 in endothelial activation.
5. Use of an inhibitor of the Gas6 function and/or an inhibitor of a Gas6 receptor for the manufacture of a medicament for the treatment of endothelial dysfunction.
6. Use according to claim 5 in which endothelial dysfunction results in a cardiovascular disorder such as, but not limited to, stroke, arterial restenosis, myocardial infarction.
7. Use according to claim 5 in which endothelial dysfunction results in abnormal angiogenesis.
8. Use according to claim 57 in which the Gas6 receptor is AXL, MER and/or RSE.
9. Use according to claim 8 in which the inhibitor is a soluble form of the AXL, MER or RSE receptor.

Claims: 1-4 Non-human transgenic animal deficient in Gas6 function and its use. 2. Claims: 10; in part: 5-7 Use of an inhibitor of the Gas6 function for the manufacture of a medicament. 3. Claims: 8,9; in part: 5-7 Use of an inhibitor of a Gas6 receptor for the manufacture of a medicament. FURTHER INFORMATION CONTINUED FROM PCT/ISA/210 Continuation of Box 1. 2 Claims Nos.: in part: 5-8 Claims 5-8 refer to an inhibitor of the Gas6 function and/or an inhibitor of a Gas6 receptor without giving a true technical characterization. Moreover, no such specific inhibitors are defined in the application. In consequence, the scope of said claims is ambiguous and vague, and its subject-matter is not sufficiently disclosed and supported (Art. 5 and 6 PCT). No complete search can be carried out for such purely speculative claims whose wording is, in fact, a mere recitation of the result to be achieved. Therefore, the search was limited to inhibitors which are either a soluble form of the AXL, MER or RSE receptor or a Gas6 antibody. The applicant's attention is drawn to the fact that claims, or parts of claims, relating to inventions in respect of which no international search report has been established need not be the subject of an international preliminary examination (Rule 66.1 (e) PCT). The applicant is advised that the EPO policy when acting as an International Preliminary Examining Authority is normally not to carry out a preliminary examination on matter which has not been searched. This is the case irrespective of whether or not the claims are amended following receipt of the search report or during any Chapter II procedure.
