Weinberg has been instrumental in studies of oncogenes, genes that can spark the rapid cell multiplication associated with cancerous tumors. Now, in two studies published over the past month, Weinberg and colleagues present clues as to how tumors spread through the body. They found that microRNAs, small molecules that typically disrupt protein production by binding to the messenger RNAs that transmit DNA instructions for proteins, can cause tumors to metastasize. Could the research help curb the spread of cancer within people? We'll talk about the research.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciencefriday.com/program/archives/200710123"><DIV class="lbox"> <H2>Listen:</H2> <DIV id="player"> <BR /><A id="showlisten" href="#">more audio options</A> <DIV id="listenoptions" class="hidethis">streaming: <A href="http://www.npr.org/dmg/dmg.php?prgCode=TOTN&showDate=12-Oct-2007&segNum=3&mediaPref=RM"><IMG width="12" height="12" border="0" alt="streaming RealAudio" src="http://www.sciencefriday.com/audio/rm.gif" />RM</A> <BR />download: <A href="http://podcastdownload.npr.org/anon.npr-podcasts/podcast/510221/15242866/npr_15242866.mp3"><IMG width="12" height="12" border="0" alt="mp3 download" src="http://www.sciencefriday.com/audio/mp3.gif" /> mp3</A> <BR /><A href="http://www.npr.org/audiohelp/index.html">NPR audio help </A><BR /> <A href="http://www.sciencefriday.com/audio/scifriaudio.xml"><IMG width="36" height="14" border="0" src="http://www.sciencefriday.com/audio/xml.gif" /> podcast </A> (<A href="http://www.sciencefriday.com/audio/index.html">what's this?</A>)</DIV> </DIV> <H2>Tools:</H2> <DIV id="share"><UL><li style="margin-left:16px;padding-left: 0px;"><A href="javascript:alert('This link contains javascript.
