In muscle, androgens act as anabolic agents that increase both muscle mass and strength; however, a key unanswered question is the mechanism through which AR-mediated gene expression leads to these effects. To gain further insight into the mechanism of AR action in muscle, we identified AR-binding sites in primary human muscle cells using ChIP-on-Chip (chromatin immunoprecipitation coupled with tiling microarray detection of genomic fragments). Through this analysis, we identified 32,518 potential AR-binding sites throughout the genome that were enriched upon androgen treatment. Sequence analysis of these regions indicated that approximately 90% possess a consensus androgen response element or half-site. Among the identified AR-binding sites are genes known to be directly regulated by AR, confirming the validity of our methodology. Additionally, we identified a number of novel AR targets, including genes and micro-RNAs implicated in muscle differentiation and function, suggesting a direct role for AR-mediated transcription in muscle development. Intriguingly, binding sequences for the Mef2 family of transcription factors were enriched in the AR-bound regions, and we show that several Mef2c-dependent genes are direct targets of AR, suggesting a functional interaction between Mef2c and AR in skeletal muscle. Our results provide new insights into the mechanisms by which androgens promote muscle growth and validate AR as a potential therapeutic target for sarcopenia, muscle wasting, and other androgen-related muscle disorders.<\/jats:p>","DOI":"10.1210\/me.2010-0138","type":"journal-article","created":{"date-parts":[[2010,7,8]],"date-time":"2010-07-08T02:37:02Z","timestamp":1278556622000},"page":"1665-1674","source":"Crossref","is-referenced-by-count":90,"title":["Research Resource: The Androgen Receptor Modulates Expression of Genes with Critical Roles in Muscle Development and Function"],"prefix":"10.1210","volume":"24","author":[{"given":"Anastasia","family":"Wyce","sequence":"first","affiliation":[{"name":"Transcriptional Targets, Tissue Repair (A.W., S.N., C.C.T.), Collegeville, Pennsylvania 19426"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuchen","family":"Bai","sequence":"additional","affiliation":[{"name":"Biological Technology (Y.B.), Pfizer Biotherapeutics, Collegeville, Pennsylvania 19426"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sunil","family":"Nagpal","sequence":"additional","affiliation":[{"name":"Transcriptional Targets, Tissue Repair (A.W., S.N., C.C.T.), Collegeville, Pennsylvania 19426"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine C.","family":"Thompson","sequence":"additional","affiliation":[{"name":"Transcriptional Targets, Tissue Repair (A.W., S.N., C.C.T.), Collegeville, Pennsylvania 19426"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"80","reference":[{"key":"2020071614050159500_R1","doi-asserted-by":"crossref","first-page":"522","DOI":"10.1038\/bjp.2008.118","article-title":"Cellular and molecular mechanisms responsible for the action of testosterone on human skeletal muscle.
