    LA PLASTICIDAD CELULAR ESTA EN LA BASE DE LOS MECANISMOS QUE GOBIERNAN LA MORFOGENESIS DEL EMBRION Y TAMBIEN LA PROGRESION DEL CANCER. LA PRIMERA ETAPA DE LA CASCADA METASTASICA IMPLICA UN CAMBIO EN EL COMPORTAMIENTO DE LAS CELULAS TUMORALES, PUES SE INICIA CUANDO LAS CELULAS EPITELIALES DEL TUMOR PRIMARIO SUFREN UNA TRANSICION EPITELIO-MESENQUIMA (O EMT, DE SUS SIGLAS EN INGLES) MEDIADA POR LA ACTIVACION DE UNOS FACTORES DE TRANSCRIPCION DENOMINADOS (EMT-TFS). LOS EMT-TFS PROMUEVEN EL DESPRENDIMIENTO DE CELULAS DEL TUMOR PRIMARIO, LA INVASION DE TEJIDOS ADYACENTES Y CONFIEREN RESISTENCIA A LA MUERTE CELULAR Y A LA QUIMIO E INMUNOTERAPIA. ADEMAS, LA EMT SE HA RELACIONADO CON LA ADQUISICION DE PROPIEDADES DE CELULAS MADRE O CELULAS INICIADORAS DE TUMORES. EN EL LABORATORIO, LLEVAMOS MAS DE 20 AÑOS ESTUDIANDO LA EMT DURANTE EL DESARROLLO EMBRIONARIO Y SU REACTIVACION EN SITUACIONES PATOLOGICAS COMO LA FIBROSIS O EL CANCER, Y RECIENTEMENTE HEMOS CARACTERIZADO UN NUEVO TIPO DE EMT-TF, REPRESENTADO POR PRRX1 QUE SIENDO UN POTENTE INDUCTOR DE EMT, REPRIME LAS PROPIEDADES ASOCIADAS A LAS CELULAS MADRE. ESTOS RESULTADOS MUESTRAN QUE (I) LA EMT Y LAS PROPIEDADES INICIADORAS DE TUMORES SE REGULAN DE FORMA INDEPENDIENTE, Y QUE (II) LOS EMT-TFS SON MAS HETEROGENEOS DE LO QUE SE PENSABA INICIALMENTE. LAS CELULAS TUMORALES EXPRESAN COMBINACIONES DE EMT-TFS QUE DEBEN REPRIMIR PARA PARAR EL PROGRAMA MIGRATORIO CUANDO ALCANZAN ORGANOS DISTANTES Y FORMAR METASTASIS, LO QUE INDICA UN GRADO DE PLASTICIDAD Y HETEROGENEIDAD ADICIONAL QUE REPRESENTA UN RETO MAS PARA EL DISEÑO DE TERAPIAS ANTIMETASTASICAS. _x000D_ _x000D_ APROVECHANDO NUESTRA EXPERIENCIA EN EL ESTUDIO DE LA EMT NORMAL Y PATOLOGICA, PROPONEMOS ABORDAR LOS SIGUIENTES OBJETIVOS GENERALES:_x000D_ _x000D_ ESTUDIAR LA HETEROGENEIDAD Y PLASTICIDAD CELULAR DE LAS CELULAS TUMORALES DESDE EL TUMOR PRIMARIO HASTA LA METASTASIS _x000D_ GENERAREMOS NUEVOS MODELOS ANIMALES QUE COMBINEN REPORTEROS DE LA EXPRESION DE EMT-TFS CON MARCADORES DE LINAJE CELULAR PARA ESTUDIAR ESTOS PROCESOS CON UNA NUEVA RESOLUCION ESPACIOTEMPORAL IN VIVO _x000D_ _x000D_ ESTUDIAR LAS SEÑALES QUE GOBIERNAN LA PLASTICIDAD CELULAR EN EL NICHO METASTASICO _x000D_ REALIZAREMOS UN CRIBADO DE MICROAMBIENTES COMBINATORIOS PARA IDENTIFICAR NUEVAS SEÑALES Y MOLECULAS QUE REGULEN LA PLASTICIDAD CELULAR EN EL NICHO METASTASICO Y DEFINIR MICROAMBIENTES FAVORABLE A LA COLONIZACION QUE PERMITA SELECCIONAR CANDIDATOS PARA TERAPIAS ANTIMETASTASICAS _x000D_ _x000D_ IDENTIFICAR DOMINIOS EN LOS EMT-TFS QUE INSTRUYAN COMPORTAMIENTOS CELULARES RELEVANTES PARA LA COLONIZACION METASTASICA _x000D_ LA CARACTERIZACION FUNCIONAL IN VITRO E IN VIVO DE ESTE TIPO DE MODULOS EN LOS EMT-TFS PERMITIRA PROPONER NUEVAS DIANAS MAS ESPECIFICAS _x000D_ _x000D_ IDENTIFICAR NUEVAS REDES DE REGULACION GENICA (GRNS) Y NUEVOS CIRCUITOS DE REGULACION RECIPROCA (RRLS) QUE REGULEN LA PLASTICIDAD EPITELIAL _x000D_ LA DESCRIPCION Y EL ANALISIS FUNCIONAL DE NUEVOS GRNS Y RRLS PUEDEN DESVELAR NUEVOS NODOS PARA INTERVENCION TERAPEUTICA _x000D_ _x000D_ PROPONEMOS LA GENERACION DE NUEVOS MODELOS ANIMALES Y LA UTILIZACION DE CELULAS EN CULTIVO, EMBRIONES DE POLLO Y EMBRIONES DE PEZ CEBRA PARA INCREMENTAR LA CAPACIDAD DE ANALISIS Y SELECCIONAR LOS MEJORES CANDIDATOS. EL DISEÑO GLOBAL NOS PERMITE INTERCONECTAR LOS DISTINTOS OBJETIVOS Y OPTIMIZAR LOS RESULTADOS. ANALIZAREMOS MUESTRAS DE PACIENTES PARA CONTRASTAR NUESTROS RESULTADOS EN UN CONTEXTO MEDICO, EN EL ANIMO DE CONTRIBUIR A UNO DE LOS RETOS MAS IMPORTANTES EN LA INVESTIGACION DEL CANCER, PREVENIR LA FORMACION DE METASTASIS (Spanish)

    CELLULAR PLASTICITY IS AT THE BASIS OF THE MECHANISMS THAT GOVERN EMBRYO MORPHOGENESIS AND ALSO THE PROGRESSION OF CANCER. THE FIRST STAGE OF THE METASTASICA CASCADE INVOLVES A CHANGE IN THE BEHAVIOR OF THE TUMOR CELLS, SINCE IT BEGINS WHEN THE EPITHELIAL CELLS OF THE PRIMARY TUMOR UNDERGO AN EPITHELIUM-MESENCHYMA TRANSITION (OR EMT) MEDIATED BY THE ACTIVATION OF SOME SO-CALLED TRANSCRIPTION FACTORS (TTF-TFS). EMT-TFS PROMOTES THE DETACHMENT OF CELLS FROM THE PRIMARY TUMOR, THE INVASION OF ADJACENT TISSUES AND CONFERS RESISTANCE TO CELL DEATH AND CHEMO AND IMMUNOTHERAPY. IN ADDITION, EMT HAS BEEN LINKED TO THE ACQUISITION OF PROPERTIES OF STEM CELLS OR TUMOR-INITIATING CELLS. IN THE LABORATORY, WE HAVE BEEN STUDYING EMT FOR MORE THAN 20 YEARS DURING EMBRYONIC DEVELOPMENT AND ITS REACTIVATION IN PATHOLOGICAL SITUATIONS SUCH AS FIBROSIS OR CANCER, AND RECENTLY WE HAVE CHARACTERISED A NEW TYPE OF EMT-TF, REPRESENTED BY PRRX1 THAT BEING A POTENT INDUCER OF EMT, SUPPRESSES THE PROPERTIES ASSOCIATED WITH STEM CELLS. THESE RESULTS SHOW THAT (I) EMT AND TUMOR-INITIATING PROPERTIES ARE INDEPENDENTLY REGULATED, AND (II) EMT-TFS ARE MORE HETEROGENEOUS THAN INITIALLY THOUGHT. TUMOR CELLS EXPRESS COMBINATIONS OF EMT-TFS THAT MUST BE REPRESSED TO STOP THE MIGRATION PROGRAM WHEN THEY REACH DISTANT ORGANS AND FORM METATASIS, INDICATING AN ADDITIONAL DEGREE OF PLASTICITY AND HETEROGENEITY THAT REPRESENTS A FURTHER CHALLENGE FOR THE DESIGN OF ANTIMETASTASIC THERAPIES. _x000D_ _x000D_ leveraging OUR EXPERIENCE IN THE STUDY OF THE NORMAL AND PATOLOGICAL EMT, we PROPONATE THE GENERAL NEXT OBJECTIVES:_x000D_ _x000D_ STUDY THE heterogeneity and CELL PLASTICITY OF THE TUMORAL CELULAS first TUMOR HAS THE METASTASIS _x000D_ we will generate NEW ANIMAL MODELS that combine EMT-TFS EXPRESSION REPORTS with CELL LINACE Markers to study these products with a new IN VIVO space-time resolution _x000D_ _x000D_ signs GOVERNING CELL PLASTICITY in the metastatic NICHO _x000D_ RELATED A CRIBATED of combinatorial microenvironments to IDENTIFICATE NEW Signals and molecules that regulate the CELL PLASTICITY in the metatasic NICHO and DEFIN microenvironments FAVORABLE to the colonisation that allows to select ANTIMETASTASIC TERAPITS CANDIDATS _x000D_ _x000D_ IDENTIFICATE DOMAINS IN EMT-TFS that instruct RELEVANT CELLAR COMPORTS FOR METASICAL colonisation _x000D_ FUNCTIONAL CHARACTERISATION IN VITRO AND IN LIVE OF THIS TYPE OF MODULES IN VITRO AND IN LIVE EMT-TFS will allow to PROPONER NEW SPECIFIC DAYS _x000D_ _x000D_ IDENTIFICATE NEW GENICAL REGULATION NATIONS (GRNS) AND NEW REGULATION CIRCUITS RECIPROCATION (RRLS) Regulating EPITELIAL PLASTICITY _x000D_ DESCRIPCION and the FUNCTIONAL ANALISIS OF NEW GRNS AND RRLS can unveil new nodes for terapeutic internationalisation _x000D_ _x000D_ PROPONE USE OF NEW ANIMAL MODELS AND Utilisation of CELULS IN CULTIVO, chicken EMBRIONS and CEBRA PEZ EMBRIONS to increase the capacity of Analyses and select the best candidates.
