Research lines: -Biological role of caveolin-1 in sarcomas Funding: Mecanismos moleculares regulados por caveolina-1 durante la progresión tumoral del sarcoma de Ewing Funding Agency: ISCIII 2012-2014 Regulación de la angiogénesis en el sarcoma de Ewing: papel de la caveolina-1 Funding Agency: ISCIII 2009-2011 Estudio del proceso metastásico en la familia de tumores del sarcoma de Ewing: función biológica de la caveolina-1 Funding Agency: ISCIII 2007-2009 Startup grant
-Biological role of caveolin-1 in sarcomas Ewing s sarcoma: We have demonstrated the involvement of this protein in the resistance to chemotherapy and their ability cells to metastasize. We are currently investigating its involvement in the regulation of blood supply and the possible mechanisms by which controls such processes (Dr Àngels Fabra from the Biological clues of the invasive and metastasic phenotype Group).

-Identification of new therapeutic targets and preclinical evaluation of new compounds for the treatment of sarcomas. Funding: FUS/CHOP as therapeutic target in Myxoid/Cell Round Liposarcoma. Sponsor: GEIS Sirolimus 2009-2010 PI: Oscar Martinez Phase I/II clinical trial of the combination gemcitabine plus rapamycin vs gemcitabine alone in soft tissue sarcomas. Funding Agency: Ministerio de Sanidad y Política Social Sirolimus 2010-2012 PI: Xavier García del Muro Phase I/II clinical trial to assess security and eficacy of Sorafenib (BAY43-9006) and Iphosphamide combination in the treatment of soft tissue sarcoma patients Ongoing PI: Xavier García del Muro
-Identification of new therapeutic targets and preclinical evaluation of new compounds for the treatment of sarcomas. We are testing in vitro and in vivo several new compounds on soft tissue sarcoma cell lines to obtain preclinical data for future clinical trials. mtor inhibitors: We are currently testing mtorc1 and mtorc2 inhibitors on myxoid liposarcomas and Ewing s sarcomas and exploring the mechanisms by which they are effective. We are interested in dual PI3K/mTOR inhibitors and MEK inhibitors (everolimus +MEK162) CDK s inhibitors: We are currently testing these inhibitors in several soft tissue sarcomas. Glucose inhibitors for the treatment of rhabdomyosarcomas (Collaboration with Cristina Muñoz Pinedo from the Cell Death Regulation Group)
