Resumen
En la actualidad las tasas de cáncer de colon en los países industrializados están aumentando considerablemente, estando la dieta claramente relacionada. Numerosas son las investigaciones que intentan clarificar componentes o patrones de dieta. Varios son los mecanismos de acción por los que los ácidos grasos modulan la función inmune, como la alteración celular , alteración en el estado oxidativo, regulación de la expresión génica e inducción de la apoptosis. Gracias a esta capacidad inmunomoduladora y antiinflamatoria, los ácidos grasos poli y monoinsaturados pueden ser útiles en la prevención del cáncer de colón. Por otro lado, la inflamación crónica del intestino puede estar relacionada con el desarrollo de este tipo de tumor. Nuestra hipótesis de trabajo es que la combinación de aquellos componentes, como los ácidos grasos y los microorganismos probióticos, que han demostrado poseer cierta actividad anti-inflamatoria, pueden resultar útiles en la prevención y tratamiento. Para ello proponemos el estudio de estos dos componentes de la dieta en un modelo animal de cáncer de colon asociado a colitis ulcerosa.
At present, the rates of colon cancer in industrialized countries are increasing considerably, and diet is clearly related. Numerous are the investigations that try to clarify components or patterns of diet. There are several mechanisms of action by which fatty acids modulate immune function, such as cell alteration, oxidative state alteration, gene expression regulation and apoptosis induction. Thanks to this immunomodulatory and anti-inflammatory capacity, poly and monounsaturated fatty acids can be useful in the prevention of colon cancer. On the other hand, chronic inflammation of the intestine may be related to the development of this type of tumor. Our working hypothesis is that the combination of those components, such as fatty acids and probiotic microorganisms, which have been shown to have a certain anti-inflammatory activity, may be useful in prevention and treatment. For this we propose the study of these two components of the diet in an animal model of colon cancer associated with ulcerative colitis.
