Abstract: Peptides and mimetics of selected domains of mammalian serum amyloid A isoform 2.1 (SAA2.1) and compounds and compositions thereof are provided that enhance the effect on macrophage cholesterol ester hydrolase activity and/or inhibit acyl CoA:cholesterol acyl transferase activity. Methods of using these compositions in the treatment and/or prevention of atherosclerosis as well as coronary heart disease and cardiovascular disease are also provided.

Abstract: Synthetic peptides containing an ankyrin repeat-like motif or portion thereof and mimetics thereof which interact with synuclein-gamma (SNCG) and reduce SNCG-mediated resistance of SNCG-expressing cancer cells to treatment with anticancer drugs or inhibit tumorigenesis and cancer cell proliferation are provided. Compositions containing these peptides, portions thereof or mimetics thereof are also provided. Methods for use of these peptides or portions thereof, compositions, and mimetics thereof in potentiating efficacy of anticancer drugs, in particular microtubule inhibitors and hormonal cancer therapies, and in treating cancer are also provided.

Abstract: The present invention provides methods for determining the structure and/or function of one or more domains of a cation-dependent (and preferably calcium-dependent) polypeptide (particularly a calcium-dependent enzyme, which may be a protease such as calpain) in the presence of one or more cations. The invention further provides methods for identifying a ligand having the ability to bind to one or more ligand-binding domains (LBDs) of a cation-dependent (and preferably calcium-dependent) polypeptide, and ligands identified by these methods. The invention also provides methods of treating or preventing physical disorders in animals using these ligands.
