Resumen
El presente TFM se centra en la caracterización histoquímica de los efectos de una dieta enriquecida con subproductos derivados del olivar en el pez cebra (Danio rerio). En el estudio se evalúa cómo diferentes componentes de la dieta afectan a la acumulación de grasa en dichos peces. Se utilizó aceite de oliva, aceite de girasol y aceites de semilla y de pulpa de aceituna, siendo comparados con un grupo control alimentado con una dieta estándar. Mediante técnicas moleculares se estudiaron diferentes genes relacionados con factores de transcripción lipogénicos, así como con la absorción de lípidos. También se utilizaron técnicas histoquímicas en las que se analizaron los tejidos de hígado e intestino de los peces cebra para identificar la presencia y la distribución de los lípidos. Estos trabajos se completaron mediante la técnica de Western Blot que permitió la inmunodetección de la proteína FABP2, relacionada con el metabolismo de la grasa.
This TFM focuses on the histochemical characterization of the effects of a diet enriched with by-products derived from olive trees in zebrafish (Danio rerio). The study evaluates how different dietary components affect fat accumulation in these fish. Olive oil, sunflower oil, olive seed and pulp oil were used and compared with a control group fed with a standard diet. Molecular techniques were employed to study various genes related to lipogenic transcription factors as well as lipid absorption. Histochemical techniques were also used to analyze liver and intestine tissues of the zebrafish to identify the presence and distribution of lipids. These works were completed using the Western Blot technique that allowed the immunodetection of the FABP2 protein, related to fat metabolism.
