OT; George or anyone: What conclusions re endostatin to draw from this? <a href="http://www.endocrine-abstracts.org/ea/0020/ea0020P192.htm" rel="nofollow" target="_blank">http://www.endocrine-abstracts.org/ea/0020/ea0020P192.htm</a> I have no idea what "endogenous TSH" is, but wonder whether it could have played a part in the lack of efficacy of endostatin in the ENMD human trials.
