Abstract:
The present invention describes a novel interaction between Smad6 and the Hox genes in nuclear transcriptional regulation following BMP signal transduction. The present invention further provides methods of using this novel Smad6/Hox protein interaction to regulate gene expression, regulate bone formation and control osteoporosis. Further provided are methods of screening for compounds that interfere with the novel Smad6/Hox protein interaction, thereby resulting in expression of a Hox protein-repressed gene and/or stimulating bone formation.
Compositions And Methods For Improving Bone Mass Through Modulation Of Receptors Of Pth And Fragments Thereof
The present invention relates to the discovery of novel receptors for the signaling of PTH and/or fragments of PTH, and the role of cPTH in bone development. The novel PTH receptors identified are selected from the group consisting of LRP5/6, TGFβRII, BMPRII (long form and short form), ActRIIA, and ActRIIB. Specifically, the present invention provides a novel screening tool for identifying compounds that improve bone mass by affecting certain pathways that promote or downregulate bone-forming activity. This promotion of bone-forming activity could provide for treatments for bone-loss or bone density disorders and/or kidney disease. The invention further encompasses the compounds, PTH ligands, and fragments of PTH ligands described herein; pharmaceutical compositions comprising the compounds, PTH ligands, or fragments of PTH ligand; and methods of increasing bone density using the compounds, PTH ligands, or fragments of PTH ligands.

International Classification:

US Classification:
514/044000, 435/366000
Abstract:
The present invention demonstrates that BMP-2/4 activates osteopontin gene transcription by removing Hoxc-8 binding through Smad1 interaction with the Hoxc-8 DNA binding domain. Since the DNA binding domain is conserved in all Hox and homeodomain-containing proteins, Smad1 likely interacts with all Hox or homeodomain-containing proteins. Furthermore, the present invention reveals the Smad1-mediated transcriptional mechanism in the BMP-2/4 signaling pathway and also provides information about the transcriptional roles of the Hox genes during embryonic development.

Abstract:
Provided herein are methods of screening for an agent that is a PTH agonist or antagonist. For example, provided is a method of screening for an agent that is a PTH agonist or antagonist, the method comprising contacting a cell with LRP6 and the agent to be screened, wherein the cell comprises a PTH1R, and determining the level of LRP6 binding to the PTH1R. An increased level of LRP6 binding to the PTH1R compared to a control indicates the agent is a PTH agonist. A decreased level of LRP6 binding to the PTH1R compared to a control indicates the agent is a PTH antagonist. Also provided are methods of treating a skeletal disorder in a subject, wherein the skeletal disorder is characterized by proliferative bone growth or reduced bone density.
Modulation Of Gpcr-Mediated Camp Production Through Lrp6 And Its Therapeutic Application
The present invention relates to low-density lipoprotein receptor related protein 6 (LRP6). More specifically, the present invention relates to targeting of LRP6 to modulate Gαactivity. In one embodiment, a method of screening for antagonists of IRP6-Gαinteraction comprises the steps of (a) contacting an agent that binds LRP6 with a cell; and (b) measuring the level of cAMP production in the cell in response to one or more GPCR ligands, wherein an agent that decreases cAMP production as compared to cAMP production in the cell not contacted with the agent identifies the agent as an antagonist of LRP6-Gαinteraction.

Compositions And Methods For Treating Disorders Characterized With Excessive Osteoclast Activity
Provided herein are compositions and methods directed to treating, delaying progression of, or reducing cancer growth or metastasis, and the severity of disorders characterized with increased osteoclast activity through hindering and/or inhibiting osteoclastogenesis and/or osteoclast activity. In particular, the present invention provides compositions and methods directed to hindering and/or inhibiting Siglec15 and sialylated TLR (e.g., TLR2, TLR4) interaction by specific sialyltransferases.
