Abstract: Antagonists to Dickkopf-1 (Dkk-1) protein are administered in effective amounts to treat disorders involving insulin resistance, such as non-insulin-dependent diabetes mellitus (NIDDM), hypoinsulinemia, and disorders involving muscle atrophy, trauma, or degeneration. Preferably, the antagonists are composed of compositions comprising antibodies directed to Dkk-1 in a pharmaceutically acceptable carrier for use in blocking the effects of Dkk-1. Additionally provided is a method of treating obesity or hyperinsulinemia in a mammal by administering an effective amount of Dkk-1 to a mammal. Also provided are methods of diagnosing insulin resistance, hyper- and hypoinsulinemia, obesity, and related disorders using Dkk-1 as a target and non-human transgenic animals that overexpress dkk-1 nucleic acid.

Abstract: Dickkopf-5 (Dkk-5) protein is administered in effective amounts to treat disorders involving insulin resistance, such as non-insulin-dependent diabetes mellitus (NIDDM) or obesity. Also provided is a method of diagnosing insulin resistance and related disorders using Dkk-5 as a measure, and kits for diagnosis and treatment, as well as hybridomas producing antibodies to Dkk-5 and preparations comprising Dkk-5.
