Abstract
Primary contents of dietary fat are three or four types of fatty acids, namely saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), n6-polyunsaturated fatty acid (n6PUFA) and, to less extent, n3-polyunsaturated fatty acid (n3PUFA). Previous studies suggest that increased SFA, MUFA, and n6PUFA in high fat diets (HFDs) stimulate the origination, growth, and liver metastasis of pancreatic cancer cells, whereas increased n3PUFA has the opposite effects. It is unclear whether the fatty acid-induced effects are based on changed fatty-acid composition of involved cells. Here, we investigated whether increased SFA, MUFA, n6PUFA, and n3PUFA in different HFDs determine the FA profiles of pancreatic cancer cells and their carrier's plasma, pancreas, and liver. We transplanted MiaPaCa2 human pancreatic cancer cells in athymic mice and fed them normal diet or four HFDs enriched with SFA, MUFA, n6PUFA, and n3PUFA, respectively. After 7 weeks, fatty acids were profiled in tumor, plasma, pancreas, and liver, using gas chromatography. When tumor carriers were fed four HFDs, the fatty acids that were increased dietarily were also increased in the plasma. When tumor carriers were fed MUFA-, n6PUFA-, and n3PUFA-enriched HFDs, the dietarily increased fatty acids were also increased in tumor, pancreas, and liver. When tumor-carriers were fed the SFA-enriched HFD featuring lauric and myristic acids (C12:0 and C14:0), tumor, pancreas, and liver showed an increase not in the same SFAs but palmitic acid (C16:0) and/or stearic acid (C18:0). In conclusion, predominant fatty acids in HFDs determine the fatty-acid profiles of pancreatic cancer cells and their murine carriers.

Abstract
Skin models with efficient skin barrier function are required for percutaneous absorption studies. The contribution of media supplementation with n-3 and n-6 polyunsaturated fatty acids (PUFAs) to the development of the skin barrier function of in vitro skin models remains incompletely understood. To investigate whether PUFAs, alpha-linolenic acid (ALA, n-3 PUFA) and linoleic acid (LA, n-6 PUFA), could enhance the impermeability of a three-dimensional reconstructed human skin model, skin substitutes were produced according to the self-assembly method using culture media supplemented with either 10 μM ALA or 10 μM LA. The impact of PUFAs on skin permeability was studied by using a Franz cell diffusion system to assess the percutaneous absorption of testosterone and benzoic acid. Our findings showed that ALA supplementation induced a decrease in the absorption of testosterone, while LA supplementation did not significantly influence the penetration of testosterone and benzoic acid under present experimental conditions. Both ALA and LA were incorporated into phospholipids of the skin substitutes, resulting in an increase in n-3 total PUFAs or n-6 total PUFAs. Collectively, these results revealed the under-estimated impact of n-3 PUFA supplementation as well as the importance of the n-6 to n-3 ratio on the formation of the skin barrier of in vitro reconstructed human skin models.

Abstract
This study has evaluated the effect of EVOO (Extra-Virgin olive oil), OA (oleic acid) and HT (hydroxytyrosol) in an induced model of MS through experimental autoimmune encephalomyelitis (EAE).Dark Agouti 2-month old rats (25 males) were divided into five groups: (i) control group, (ii) EAE group, (iii) EAE+EVOO, (iv) EAE+HT, and (v) EAE+OA. At 65 days, the animals were sacrificed and the glutathione redox system and bacterial lipopolysaccharide (LPS) and LPS-binding protein (LBP) products of the microbiota in brain, spinal cord, and blood were evaluated.Gastric administration of EVOO, OA, and HT reduced the degree of lipid and protein oxidation, and increased glutathione peroxidase, making it a diet-based mechanism for enhancing protection against oxidative damage. In addition, it reduced the levels of LPS and LBP, which appeared as being increased in the EAE correlated with the oxidative stress produced by the disease.

Abstract
Olive oil is a major component of the Mediterranean diet, and its role in human health is being actively debated. This study aimed to clarify the mechanism of pancreatic adaptation to dietary fat. For this purpose, we examined whether dietary-induced modification of pancreatic membranes affects acinar cell function in response to the secretagogue acetylcholine (ACh). Weaning male Wistar rats were assigned to one of two experimental groups and fed for 8 weeks with a commercial chow (C) or a semisynthetic diet containing virgin olive oil as dietary fat (OO). The fatty acid composition of pancreatic plasma membranes was determined by gas-liquid chromatography. For assessment of secretory function, viable acini were incubated with ACh and amylase of supernatant was further assayed with a substrate reagent. Changes in cytosolic Ca(2+) concentration in response to ACh were measured by fura-2 AM fluorimetry. Compared to C rats, pancreatic cell membranes of OO rats had a higher level of monounsaturated fatty acids and a lower level of both saturated and polyunsaturated fatty acids, thus, reflecting the type of dietary fat given. Net amylase secretion in response to ACh was greatly enhanced after OO feeding, although this was not paralleled by enhancement of ACh-evoked Ca(2+) peak increases. In conclusion, chronic intake of diets that differ in the fat type influences not only the fatty acid composition of rat pancreatic membranes but also the responsiveness of acinar cells to ACh. This mechanism may be, at least in part, responsible for the adaptation of the exocrine pancreas to the type of fat available.
