Summary for Patent: 7,258,999
Title:PTH responsive gene
Abstract: This invention relates to a novel PTH gene. The invention further relates to methods of screening, diagnosis and development of therapies for bone related disorders.
Inventor(s): Robinson; John Allen (Downingtown, PA), Stojanovic-Susulic; Vedrana (Princeton Junction, NJ), Babij; Philip (Dunstable, MA), Murrills; Richard John (Yardley, PA)
Assignee: Wyeth (Madison, NJ)
Application Number:10/705,716
Patent Claims:1. An isolated polypeptide encoded by an isolated nucleic acid fragment selected from the group consisting of: (a) an isolated nucleic acid fragment encoding SEQ ID NO: 2; (b) an isolated nucleic acid fragment encoding an amino acid sequence having at least 98% identity with SEQ ID NO: 2; and (c) an isolated nucleic acid fragment that hybridizes with the isolated nucleic acid fragment of (a) under hybridization conditions of 6.times.SSC (1M NaCl), 45 to 50% formamide, 1% SDS at 37.degree. C., and a wash in 0.5.times. to 1.times.SSC at 55 to 60.degree. C.; wherein said polypeptide is parathyroid hormone anabolic induced gene in bone (PAIGB) polypeptide and has osteoblast bone forming activity in bone tissues.

2. The isolated polypeptide of claim 1 having the amino acid sequence set forth in SEQ ID NO: 2.

3. The isolated polypeptide of claim 1 which is involved in parathyroid hormone signaling pathway.

4. The isolated polypeptide of claim 1 which when overexpressed induces bone forming activity in bone tissues.

5. The isolated polypeptide of claim 1 which is overexpressed in response to intermittent parathyroid hormone administration.

6. A composition for regulating bone-forming activity in a mammal comprising an isolated polypeptide of claim 1.

7. A composition according to claim 6, wherein said parathyroid hormone anabolic induced gene in bone polypeptide is from human osteoblast cells.

8. A composition according to claim 6, wherein the bone forming activity is the regulation of bone growth.

9. A composition according to claim 6, wherein the bone forming activity is the regulation of bone density.

10. The composition according to claim 6, wherein the parathyroid hormone anabolic induced gene is bone polypeptide has the amino acid sequence set forth in SEQ ID NO: 2.
