Hormonal therapy, radiotherapy, and chemotherapy all have limited durations of efficacy for men diagnosed with androgen independent disease and patients will succumb over a period of several months to two years. The androgen receptor (AR) has been suspected to play an important role in the mechanism of progression to androgen independence. This is because the AR is a transcription factor that 'normally' mediates the effects of androgen to regulate expression of genes involved in proliferation and survival of prostate cells. Thus identifying and characterizing the proteins that interact with the AR to facilitate an activated receptor is of critical importance. Proteomic approaches such as isotope-coded affinity tags (ICAT), isotope Tags for Relative and Absolute Quantification (iTRAQ)(TM), Stable Isotope Labeling with Amino acids in Cell culture (SILAC), Tandem Affinity Purification (TAP) of tagged proteins (TAP-tag) and Multidimensional Protein Identification Technology (MudPIT) provide large scale unbiased strategies and have not been previously applied to identify proteins that interact with the AR. Here an example of the power of these proteomic approaches to identify potential therapeutic targets for prostate cancer is provided. Application of MudPIT identified 82 peptides in endogenous complexes immunoprecipitated with the AR from prostate cancer cells. Identification of these novel proteins may ultimately lead to the development of better therapies for the treatment or prevention of advanced prostate cancer.</p>","PeriodicalId":87394,"journal":{"name":"Cellscience","volume":"3 1","pages":"61-81"},"PeriodicalIF":0.0,"publicationDate":"2006-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1762136/pdf/nihms14713.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26474510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Potential Role of the AMP-activated Protein Kinase in Regulation of Insulin Action.","authors":"Jonathan S Fisher","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Because of the predominant role of skeletal muscle in insulin-stimulated clearance of blood glucose, understanding mechanisms for increasing the ability of muscle to respond to insulin could potentially lead to novel strategies for treatment or prevention of diabetes. Recently, the AMP activated protein kinase (AMPK) has emerged as a promising candidate for potentiation of insulin action. Several antidiabetic drugs have been shown to activate AMPK, cellular stresses such as exercise that increase AMPK activity also increase insulin action, and several downstream targets of AMPK seem to be involved in regulation of insulin action. Although the picture is currently incomplete, it seems possible that AMPK or one of its effectors is a positive regulator of insulin-stimulated glucose transport. In addition to discussion of the latest literature regarding AMPK and insulin action, this review includes a non-technical summary for students, academics from other fields, interested professionals, and the general public.</p>","PeriodicalId":87394,"journal":{"name":"Cellscience","volume":"2 3","pages":"68-81"},"PeriodicalIF":0.0,"publicationDate":"2006-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2099311/pdf/nihms-22037.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41046597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
