Experimental Therapeutics Group

Strategic Goals

  • Discovering novel mechanisms of anti-HER2 therapy resistance
  • Identifying mechanisms of resistance to PI3K/Akt/mTOR inhibitors
  • Hypothesis-based testing of new therapeutic strategies

Current objectives

  • Translate to clinical practice the use of CDK2 and Hsp90 inhibitors
  • Study the efficacy of novel Akt/mTOR inhibitors
  • Predict genes/pathways responsible for resistance to PI3K/Akt/mTOR inhibitors
  • Study new therapeutic combinations such as PI3K/Akt/mTOR inhibitors with MEK inhibitors or mTOR inhibitors with anti-IGF-IR agents.
  • Develop preclinical models based on tumor explants in immunocompromised mice.
