The objective of this study was to investigate the modifications induced in sea bass (Dicentrarchus labrax) by a diet supplemented with 0.025% and 0.05% carvacrol, a component of the oregano essential oil. Liver, kidney and spleen samples (5 fish/diet) were collected after 1, 4 and 8 weeks feeding in order to assess histopathological changes. In addition, liver protein pattern were investigated by using a “gel based” proteomic methodology. Liver, kidney and spleen histomorphologies were unaffected by carvacrol administration. On the contrary, the liver protein profiles showed differences between control and carvacrol supplemented fish indicating a possible active effect of this terpene on gene expression.

Abstract
The objective of this study was to investigate the modifications induced in sea bass (Dicentrarchus labrax) by a diet supplemented with 0.025% and 0.05% carvacrol, a component of the oregano essential oil. Liver, kidney and spleen samples (5 fish/diet) were collected after 1, 4 and 8 weeks feeding in order to assess histopathological changes. In addition, liver protein pattern were investigated by using a “gel based” proteomic methodology. Liver, kidney and spleen histomorphologies were unaffected by carvacrol administration. On the contrary, the liver protein profiles showed differences between control and carvacrol supplemented fish indicating a possible active effect of this terpene on gene expression.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
