Food-drug interaction: Anabolic steroids aggravate hepatic lipotoxicity and nonalcoholic fatty liver disease induced by trans fatty acids. Food Chem Toxicol 2018; 116:360-368.

Abstract
Remains unknown if dietary lipids and anabolic steroids (AS) can interact to modify energy metabolism, hepatic structure and function. We investigated the impact of AS on gene expression, lipid profile, redox status and the development of nonalcoholic fatty liver disease (NAFLD) in mice treated with a diet rich in trans fatty acids. Seventy-two C57BL/6 mice were equally randomized into six groups and treated with a standard diet (SD) or high-fat diet (HFD) alone or combined with testosterone cypionate (10 or 20 mg/kg) for 12 weeks. When combined with a HFD, AS reduced plasma HDL cholesterol levels. It also upregulated SREBP-1, PPARα, SCD-1 and ACOX1 gene expression; plasma and hepatic triglyceride levels; oxidative stress; circulating hepatic transaminase levels and NAFLD severity. Our finding indicated that the activity of antioxidant enzymes such as catalase, glutathione-s-transferase and superoxide dismutase was attenuated by HFD, an effect whose implications for AS-induced hepatotoxicity requires further investigation. Increased lipid, protein and DNA oxidative damage as well as worsening NAFLD in response to the interaction of HFD and AS were also potentially associated with the ability of AS to amplify the activation of regulatory lipid metabolism genes that are also involved in the control of cellular redox balance.

Abstract
HF diet feeding affects the energy balance by transcriptional metabolic adaptations, based in direct gene expression modulation, perinatal programing and transcriptional factor regulation, which could be affected by the animal model, gender or period of dietary treatment.

Abstract
BACKGROUND Nephrotic syndrome (NS) is an immune-mediated disorder associated with hyperlipidemia. NS has been proposed to be mediated through CD80-related T cell immune response, which could be blocked using soluble cytotoxic T lymphocyte-associated s(CTLA)-4. Although ghrelin is a hormone-modulating lipid metabolism and suppressing immune system, the precise role of ghrelin in NS is not well established. METHODS We evaluated the levels of ghrelin, soluble CD80 (sCD80) and sCTLA4 in serum and urine in doxorubicin-induced NS in rats. We also investigated the relation between their levels and the levels of serum total cholesterol (TC), triglyceride, albumin and urine protein. RESULTS While urinary ghrelin levels were significantly lower in the nephrotic rats compared to the control group, serum ghrelin levels were comparable in the nephrotic and control rats. In contrast, serum and urinary sCD80 and sCTLA4 levels were higher in the nephrotic rats than the controls. The urinary ghrelin levels were negatively correlated with the levels of serum triglyceride, TC and urine protein, sCD80 and sCTLA4. The urine sCD80 levels were positively correlated with the TC, urine protein and urine sCTLA4 levels, and negatively correlated with the serum albumin. The urine sCTLA4 levels were positively correlated with the TC and urine protein levels and negatively correlated with the serum albumin levels. In regression analysis, the urine ghrelin levels significantly relate to urine sCD80 levels. Besides, hyperlipidemia in NS did not appear to be related to serum ghrelin levels. CONCLUSION Low urine ghrelin levels might be relevant to pathogenesis of doxorubicin-induced NS. The reduction in urine ghrelin levels might also be associated with increased levels of urine sCTLA4 and sCD80 which reflect proteinuria.

Abstract
Despite the growing interest in deciphering the causes and consequences of obesity-related disorders, the mechanisms linking fat intake to bone behaviour remain unclear. Since bone fractures are widely associated with increased morbidity and mortality, most notably in elderly and obese people, bone health has become a major social and economic issue. Consistently, public health system guidelines have encouraged low-fat diets in order to reduce associated complications. However, from a bone point of view, mechanisms linking fat intake to bone alteration remain quite controversial. Thus, after more than a decade of dedicated studies, this timely review offers a comprehensive overview of the relationships between bone and fatty acids. Using clinical evidences as a starting-point to more complex molecular elucidation, this work highlights the complexity of the system and reveals that bone alteration that cannot be solved simply by taking ω-3 pills. Fatty acid effects on bone metabolism can be both direct and indirect and require integrated investigations. Furthermore, even at the level of a single cell, one fatty acid is able to trigger several different independent pathways (receptors, metabolites…) which may all have a say in the final cellular metabolic response.

Abstract
In this study, we investigated some bone parameters (bone mineral content, bone mineral density, skeleton area) in growing rats fed with a high fat diet. Correlations between bone and body composition parameters are reported. Two groups of Wistar male rats (35 days old, body mass 80 ± 6 g) were used. Water and food were given "ad libitum" during 10 weeks. Sixteen rats (L) were given a lipid enriched diet and were compared to 16 rats (S) fed with a standard diet. Body composition and bone parameters were assessed using DXA. Results indicated that L rats had lower body mass, lean body mass; fat mass was not different between the two groups. Bone mineral content, bone mineral density, skeleton area of L rats were lower compared with S rats. Significant correlations were noted between body composition, adiponectin and bone parameters. High fat diet intake during the growing period has deleterious effects on bone parameters in rats. This study confirms in growing rats that a high fat diet is pathogenic, including bone metabolism.
