Provided herein are methods to determine the safety of quercetin compositions regarding contaminants that can result from the degradation of quercetin, such as by storage of solid form quercetin compositions in an air atmosphere. The contaminants include protocatechuic acid, 2,4,6-trihydroxybenzoic acid, and 2-(3,4-dihydroxybenzoyloxy)-4,6-dihydroxybenzoic acid. Provided herein are also methods which reduce degradation of solid form quercetin compositions and reduce the formation of such toxic compounds. The provided methods increase the shelf life and patient safety of quercetin compositions.

Methods of monitoring safety of quercetin compositions

Provided herein are novel p62 compositions for the modulation of expression of a proinflammatory cytokines, osteogenic transcription factors, a bone resorptive factors and endogenous p62. Consequently, such p62 compositions are useful for prophylaxis and treatment of inflammatory diseases and related methods. In certain embodiments the inflammatory diseases are not cancer-related. In various embodiments, the inflammatory diseases include, but are not limited to osteoporosis, obesity, metabolic syndrome, type 2 diabetes, fat liver, inflammatory bowel disease, chronic pancreatitis, asthma, chronic obstructive pulmonary disease (COPD), rheumatoid arthritis (RA), osteoarthritis, multiple sclerosis (MS), psoriasis, congestive heart failure (CHF), atherosclerosis, neurodegenerative diseases (ALS, Parkinson, Alzheimer's, Huntington disease), depression, schizophrenia, gout, asbestosis and silicosis.

Methods and compositions relating to p62/SQSTM1 for the treatment and prevention of inflammation-associated diseases

Disclosed herein is a method for inducing Hsp72 production in a cell. The method involves contacting the cell transiently with a proteasome inhibitor in an amount sufficient to induce Hsp72 production. Preferably Hsp72 levels are induced to a level sufficient for the suppression of stress-activated kinase activity attributable, for example, to a stress-activated kinase selected from the group consisting of JNK and p38. The method has both in vitro and in vivo applications. Also disclosed is a method of the type described above is applied specifically to aged cells. Also disclosed is a method for treating pathologies associated with apoptosis and inflammation in an individual. The method involves administering to the individual a proteasome inhibitor in an amount sufficient to induce Hsp72 production. In a preferred embodiment of the therapeutic method, the individual is an aged individual. Stress-induced pathologies such as ischemia are particularly important with respect to the therapeutic aspect of the invention. Also disclosed is a method for identifying an organic compound having the ability to induce Hsp72 levels in aged cells to a level sufficient to suppress stress-activated kinase activity.
