Current strategy of tumor enzyme therapy is primariy based on the strictly defined differences of biochemical properties between normal and tumor cells and more precisely on their different sensitivity to deficit of essential growth factors, including amino acids. The growth inhibitory effects of these bacteria enzymes: glutamine (asparagin)ase, methionine ³-lyase and lysine ±-oxidase were demonstrated in in virto and in vivo using several tumor lines. These results suggest that commercial production of certified standard enzyme preparations and their knowledge-based rational application will provide a new potent anti-tumor preparations employed in oncology. <p><b>Key words:</b> tumor enzyme therapy, L-asparaginase, glutamin (asparagin)ase, methionine ³-lyase and lysine ±-oxidase </span></p> <b style="mso-bidi-font-weight:normal"> <hr> <p align="center"></b>[<a href="http://www.ibmc.msk.ru/pbmc/2005/5103/vol51is3.htm#1">Back</a>]<b style="mso-bidi-font-weight:normal"><b style="mso-bidi-font-weight:normal"></p> </b></b></font> </body> </html>
