Carbonaro et al. demonstrate that production of HIF-1\u03b1 protein is regulated by dynamic microtubules and that microtubule-targeting drugs shift HIF-1\u03b1 mRNA into cytoplasmic P-bodies, where its translation is repressed by miRNAs. This biosights episode presents the paper by Carbonaro et al. from the January 10, 2011, issue of&amp;nbsp; the Journal of Cell Biology, and includes an interview with authors Marisa Carbonaro and Paraskevi Giannakakou (Weill Cornell Medical College, New York, NY). Produced by Caitlin Sedwick and Ben Short. &amp;nbsp;  Subscribe to biosights via  iTunes or  RSS View biosights archive The Rockefeller University Press biosights@rockefeller.edu ","author_name":"biosights","author_url":"http:\/\/www.jcb.org\/biosights","html":"<iframe title=\"Libsyn Player\" style=\"border: none\" src=\"\/\/html5-player.libsyn.com\/embed\/episode\/id\/5957320\/height\/300\/theme\/custom\/thumbnail\/yes\/direction\/forward\/render-playlist\/no\/custom-color\/88AA3C\/\" height=\"300\" width=\"600\" scrolling=\"no\"  allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen><\/iframe>","thumbnail_url":"https:\/\/assets.libsyn.com\/secure\/item\/5957320"}
