Inhibition of migration and induction of cell death by the type II collagen amino propeptides
The present invention provides combinations and methods for inducing cell death, inhibiting angiogenesis, and inhibiting cell migration. In particular, the present invention provides methods for inducing cell death in a cell expressing an αvβ3 and/or an αvβ5 integrin.
1. A combination, the combination comprising an isolated human Type IIB collagen amino propeptide, wherein the propeptide consists of the amino acid sequence encoded by exons 3-8 of the human Type IIB collagen amino propeptide nucleic acid sequence, and an agent selected from the group consisting of an imaging agent and a therapeutic agent.
2. The combination of claim 1 , wherein the therapeutic agent is an anti-cancer agent.
3. The combination of claim 1 , wherein the human Type IIB collagen amino propeptide comprises a pharmaceutical composition.
4. The combination of claim 1 , wherein the imaging agent is an optical imaging agent.
5. The combination of claim 1 , wherein the imaging agent is a radiological imaging agent.
6. The combination of claim 1 , wherein the therapeutic agent is a chemotherapeutic agent.
7. The combination of claim 1 , wherein the therapeutic agent is a radiotherapeutic agent.
8. The combination of claim 1 , wherein the therapeutic agent is a hormonal therapeutic agent.
9. The combination of claim 1 , wherein the therapeutic agent is an immunotherapeutic agent.
