Research progress on feedback activation mechanism of mammalian target of rapamycin in tumors / 肿瘤研究与临床

As the meeting point of signaling pathways actived by growth factors and amino acids,especially leucine,in tumor cells,mammalian target of rapamycin (mTOR) plays an important role as a center factor of regulation.Recently,it was acknowledged gradually that feedback activation mechanisms of mTOR can influence the efficiency of rapamycin and its analogs in antitumor therapy.Thus,the study about feedback mechanism of mTOR and the combination therapy of mTOR inhibitors and specificd pathway inhibitors has become the hot area in cancer therapy and prevention.
