    LA SOMATOTROPINA RECOMBINANTE BOVINA RBST ES UNA HORMONA DE NATURALEZA PROTEICA CUYA ADMINISTRACION A VACAS PRODUCTORAS DE LECHE PUEDE INDUCIR UN INCREMENTO DE LA PRODUCCION DE ALREDEDOR DEL 15%. EL TRATAMIENTO DE ANIMALES PRODUCTORES DE LECHE CON ESTA SUSTANCIA ESTA PROHIBIDO EN EUROPA, ASI COMO TAMBIEN ESTA PROHIBIDA SU COMERCIALIZACION. LA RECIENTE APARICION DE INFORMACIONES EN PRENSA RELATIVAS A INCAUTACIONES DE ESTA SUSTANCIA POR PARTE DE LA GUARDIA CIVIL, HA SIDO FUENTE DE GRAN PREOCUPACION POR PARTE DE OPERADORES DEL SECTOR LACTEO EN EL ESTADO ESPAÑOL. A RAIZ DE DICHAS NOTICIAS, LOS OPERADORES DEL SECTOR LACTEO SE HAN INTERESADO TANTO POR LA EXISTENCIA DE METODOLOGIA ANALITICA PARA LA DETECCION DE DICHA SUSTANCIA, COMO POR LA EXISTENCIA DE DATOS DE RELATIVOS AL CONTROL DE LA PRESENCIA DE DICHA SUSTANCIA EN MUESTRAS DE LECHE, SIENDO ESTOS DATOS INEXISTENTES. EN ESTE MARCO SE ENCUADRA EL PRESENTE PROYECTO QUE PRETENDE TRES OBJETIVOS PRINCIPALES COMO SON: LA PUESTA A PUNTO Y MEJORA DE METODOLOGIAS DE DETECCION DE ESTA HORMONA BASADOS EN METODOS DE DETECCION POR HPLC-MS/MS, ASI COMO LA IMPLEMENTACION DE METODOLOGIAS -OMICAS PARA SU INVESTIGACION QUE PERMITAN DISCERNIR Y EVITAR LAS DIFICULTADES INHERENTES A SU DETECCION, A PARTIR DE ENSAYOS EN ANIMALES TRATADOS CONTROLADOS. UN SEGUNDO OBJETIVO SERIA INVESTIGAR EN ANIMALES TRATADOS EL GRADO DE EXPRESION DE GENES MODULADORES DEL EFECTO DE LA SOMATOTROPINA EN LOS ANIMALES, COMO EL GEN QUE EXPRESA EL IGF-I (FACTOR DE CRECIMIENTO INSULINICO) EN TEJIDOS O MUESTRAS NO INVESTIGADAS HASTA AHORA Y QUE PUEDAN PERMITIR EL CONTROL DE LOS ANIMALES TRATADOS CON RBST. COMO TERCER OBJETIVO NOS PROPONEMOS ESTUDIAR LOS EFECTOS QUE LOS TRATAMIENTOS TECNOLOGICOS MAS FRECUENTEMENTE EMPLEADOS EN LA OBTENCION DE PRODUCTOS LACTEOS (CALENTAMIENTO, DESHIDRATACION, DESNATADO, FERMENTACION, FILTRACION, ETC) TIENEN SOBRE LA PRESENCIA EN LOS PRODUCTOS FINALES DE RBST, IGF-I, ASI COMO DE LOS BIOMARCADORES RESULTANTES QUE SE CONCLUYAN EN LOS OBJETIVOS ANTERIORES. LOS RESULTADOS OBTENIDOS DEBEN DE CONSEGUIR UNA MEJORA EN LA METODOLOGIA EXISTENTE EN LA ACTUALIDAD, EN BASE A: 1) LAS VARIACIONES DEL PERFIL METABOLOMICO DE LOS ANIMALES TRATADOS EN RELACION A LOS DE REFERENCIA 2) AL GRADO DE EXPRESION DE CIERTOS GENES EN DIFERENTES TEJIDOS RELACIONADOS CON LA PRODUCCION DE IGF-1 Y 3) DESARROLLAR METODOS (BARATOS Y SENSIBLES) TANTO DE CRIBA, COMO CONFIRMATORIOS PARA EL CONTROL DEL TRATAMIENTO FRAUDULENTO EN VACUNO DE LECHE, ASI COMO PARA COMPROBAR SU POTENCIAL PRESENCIA EN LOS DIVERSOS PRODUCTOS LACTEOS EXISTENTES EN EL MERCADO.

    RECOMBINANT BOVINE SOMATOTROPIN RBST IS A HORMONE OF A PROTEIN NATURE WHOSE ADMINISTRATION TO MILK-PRODUCING COWS CAN LEAD TO AN INCREASE IN PRODUCTION OF ABOUT 15 %. THE TREATMENT OF MILK-PRODUCING ANIMALS WITH THIS SUBSTANCE IS PROHIBITED IN EUROPE, AND THE MARKETING OF MILK-PRODUCING ANIMALS IS ALSO PROHIBITED. THE RECENT APPEARANCE OF PRESS REPORTS ON SEIZURES OF THIS SUBSTANCE BY THE CIVIL GUARD HAS BEEN A SOURCE OF GREAT CONCERN ON THE PART OF OPERATORS IN THE LACTEO SECTOR IN SPAIN. ON THE BASIS OF THAT NEWS, OPERATORS IN THE LACTEO SECTOR HAVE BEEN INTERESTED IN BOTH THE EXISTENCE OF ANALYTICAL METHODS FOR THE DETECTION OF THAT SUBSTANCE AND THE EXISTENCE OF DATA RELATING TO THE MONITORING OF THE PRESENCE OF THAT SUBSTANCE IN MILK SAMPLES, AND THIS DATA DOES NOT EXIST. WITHIN THIS FRAMEWORK, THIS PROJECT AIMS AT THREE MAIN OBJECTIVES: THE DEVELOPMENT AND IMPROVEMENT OF DETECTION METHODS OF THIS HORMONE BASED ON DETECTION METHODS BY HPLC-MS/MS, AS WELL AS THE IMPLEMENTATION OF METHODS -OMICAS FOR ITS RESEARCH THAT ALLOW TO DISCERN AND AVOID THE DIFFICULTIES INHERENT IN ITS DETECTION, BASED ON TESTS IN TREATED CONTROLLED ANIMALS. A SECOND OBJECTIVE WOULD BE TO INVESTIGATE IN TREATED ANIMALS THE DEGREE OF EXPRESSION OF GENES MODULATING THE EFFECT OF SOMATOTROPIN IN ANIMALS, SUCH AS THE GENE EXPRESSING THE IGF-I (INSULINIC GROWTH FACTOR) IN TISSUES OR SAMPLES NOT PREVIOUSLY INVESTIGATED AND WHICH MAY ALLOW CONTROL OF ANIMALS TREATED WITH RBST. AS A THIRD OBJECTIVE WE PROPOSE TO STUDY THE EFFECTS THAT THE TECHNOLOGICAL TREATMENTS MOST FREQUENTLY USED IN THE PRODUCTION OF MILK PRODUCTS (HEATING, DEHYDRATION, SKIMMING, FERMENTATION, FILTRATION, ETC.) HAVE ON THE PRESENCE IN THE FINAL PRODUCTS OF RBST, IGF-I, AS WELL AS THE RESULTING BIOMARKERS THAT ARE CONCLUDED IN THE ABOVE OBJECTIVES. THE RESULTS OBTAINED MUST ACHIEVE AN IMPROVEMENT IN THE CURRENT METHODOLOGY, BASED ON: 1) VARIATIONS IN THE METABOLOMIC PROFILE OF TREATED ANIMALS IN RELATION TO THOSE OF REFERENCE 2) TO THE DEGREE OF EXPRESSION OF CERTAIN GENES IN DIFFERENT TISSUES RELATED TO THE PRODUCTION OF IGF-1 AND 3) TO DEVELOP METHODS (CHEAP AND SENSITIVE) BOTH SCREENING AND CONFIRMATORY FOR THE CONTROL OF FRAUDULENT TREATMENT IN DAIRY CATTLE, AS WELL AS TO VERIFY THEIR POTENTIAL PRESENCE IN THE VARIOUS MILK PRODUCTS AVAILABLE ON THE MARKET.
