Influencia de la luz y los patrones de alimentación sobre el reloj molecular, fisiología digestiva y comportamiento de dos peces teleósteos : lubina (Dicentrarchus labrax) y pez cebra (Danio rerio)= Influence of light and feeding patterns on the molecular clock, digestive physiology and behaviour of two teleost fishes: seabass (Dicentrarchus labrax) and zebrafish (Danio rerio).Pozo Cano, Ana del 07 June 2013 (has links)
Tesis por compendio de publicaciones / La luz y los patrones de alimentación influyeron sobre el comportamiento, fisiología y reloj molecular de dos peces teleósteos. Se clonaron dos criptocromos de lubina (cry1 y cry2), expresándose en todos los tejidos estudiados y mostrando ritmos diarios de expresión en cerebro, hígado y corazón (excepto cry2). La fase (día/noche) de alimentación a demanda en lubina afecta a los patrones diarios de actividad amilasa intestinal y expresión de period1 en tejidos periféricos (i.e. hígado), pero no en cerebro. Durante las inversiones estacionales de alimentación de la lubina, mostraron mayores valores de glucosa sanguínea durante la fase de alimentación, revelando también los mayores valores medios en lubinas nocturnas invierno. El pez cebra utilizó un nuevo comedero a demanda, mostrando independencia de fase entre ritmos circadianos de alimentación (nocturno) y locomoción (diurno), con diferentes periodicidades. Además la actividad y posición del pez cebra resultó espectro-dependiente, provocando mayores efectos las longitudes de onda cortas. / Thesis summary in English Light and feeding patterns influence on the behaviour, physiology and molecular clock of two teleost fish. Two cryptochromes (cry1 and cry2) were cloned, being expressed in all studied tissues and showing daily rhythm of expression in brain, liver and heart (except cry2). The self-seabass feeding phase (day/night) affected on daily patterns of intestinal amylase activity and on the period1 expression in peripheral tissues (i.e. liver), but not in brain. During the seasonal feeding inversions in seabass, the highest blood glucose levels were shown during their feeding phase, revealing also the highest values in nocturnal seabass in winter. Zebrafish used a new self-feeding system, displaying phase-independence between feeding (nocturnal) and locomotor (diurnal) circadian rhythms, with different periodicities. Moreover, the zebrafish activity and vertical position were spectrum-dependent, being the main effects provoked by short-wavelengths.
