Methods and Compositions Relating to p62/SQSTM1 for the Treatment and Prevention of Inflammation-Associated Diseases

Abstract

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.

1 - 17 . (canceled) 
     
     
         18 . A method for treating, alleviating, ameliorating, relieving, delaying onset of, inhibiting progression of, reducing severity of, and/or reducing incidence of one or more symptoms of a non-cancer-related chronic inflammatory disease in a subject in need,
 said method comprising administering to said subject an agent comprising p62/SQSTM1 nucleic acid that encodes a polypeptide at least 90% identical to SEQ ID NO: 2,   wherein said agent suppresses the expression of a proinflammatory cytokine in a subject.   
     
     
         19 . The method of  claim 18 ,
 further comprising administering one or more anti-inflammatory therapies.   
     
     
         20 . The method of  claim 19 ,
 wherein said one or more anti-inflammatory therapies is selected from the group consisting of: anti-inflammatory chemotherapeutic agent and biological agent.   
     
     
         21 . The method of  claim 20 ,
 wherein said anti-inflammatory chemotherapeutic agent is selected from the group consisting of: a nonsteroidal anti-inflammatory drug, a glucocorticoid, methotrexate, cyclosporine, and rapamycin.   
     
     
         22 . The method of  claim 20 ,
 wherein said biological agent is selected from the group consisting of: an anti-TNF antibody, an anti-IL1 antibody, an anti-IL6 antibody, an anti-IL6 receptor antibody, an anti-IL12/23 antibody, an anti-IL17 antibody, an anti-IL1 R antibody, an anti-IL1 receptor antagonist, and a soluble IL-1 receptor.   
     
     
         23 . The method of  claim 18 ,
 wherein said proinflammatory cytokine is selected from the group consisting of: TNF-alpha, IL-6, IL-1 beta, RANTES, IL-17, IL-23, CCL-I, MCP-5, and CXCL2.   
     
     
         24 . The method of  claim 18 ,
 wherein said non-cancer-related chronic inflammatory disease is obesity, metabolic syndrome, type 2 diabetes, fat liver, Crohn's Disease, pancreatitis, asthma, chronic obstructive pulmonary disease, arthritis, multiple sclerosis, psoriasis, congestive heart failure, atherosclerosis, depression, schizophrenia, gout, asbestosis, or silicosis.
