      <title>RU486 (mifepristone) improves cisplatin treatments</title>
      <description>While there is no patent on the drug RU486 (mifepristone),&amp;nbsp;clinical trials may be slow, however, it is available for individual patient use via the Compassionate Use Program (in the US) and TGA&amp;nbsp;(in Aust) for those for whom standard therapies have failed. Might be worth noting if you&amp;#39;ve exhausted all options.&amp;nbsp;2003: Enhancement of antitumor effect of cisplatin against human ovarian carcinoma cells by mifepristone in vivo.http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&amp;a &amp;ldquo;At a non-toxic dose, RU486 may enhance the sensitivity of tumor cells to cisplatin in vivo, possibly through the mechanism of inhibiting GcS expression at the mRNA level.&amp;rdquo;&amp;nbsp;2007: Synergistic effects of mifepristone on the cytotoxicity of cisplatin in cervical carcinoma cell lines and tumors grown in athymic micehttp://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=17 &amp;nbsp;&amp;ldquo;Analysis of the data by the isobologram method shows that the combination of mifepristone and cisplatin produced a synergistic effect in cervical cancer cells. The effect of mifepristone on the cytotoxicity of cisplatin could be mediated, at least partially, by increase of intracellular cisplatin accumulation and the down-regulation of the Bcl-2 expression. The in vivo studies showed that the combination of these agents had a significant antitumor activity against xenograft tumors.Our results suggest that mifepristone can improve the efficacy of cisplatin in cancer cells and this anti-hormonal drug therapy may be a candidate for further evaluation in combination with antineoplastic drugs in the treatment of cancer.&amp;rdquo;</description>
