Project description:Endometriosis is a benign gynecological condition that causes significant morbidity due to reduced fertility, pelvic pain and inflammatory dysfunctions. High-fat dietary intake has been linked to higher systemic inflammation and oxidative stress, which are both features of women with endometriosis. We evaluated the effects of high-fat diet (HFD) on endometriosis progression using immunocompetent mouse model wherein ectopic lesion was induced in wildtype and kruppel-like factor 9 (KLF9)- null donor mice. Results showed that HFD leads to increased ectopic lesion numbers and higher body weight gain. The HFD-promotion of lesion establishment was associated with decreased stromal estrogen receptor 1 and progesterone receptor expression, increased macrophage infiltration, and enhanced expression of pro-inflammarory and pro-oxidative stress pathway genes. Further, lesion-bearing mice had higher peritoneal fluid TNF-α and elevated local/systemic redox status than control-fed mice.

Project description:Endometriosis -associated ovarian carcinoma (EAOC) is mostly malignant transformation from endometriomas. However, the endometriosis cancerogenesis remains to be established. Using spatial transcriptomic of human specimens of normal, endometriomas and EAOC, activation of Interleukin-17C (IL-17C) signaling is identified, with higher IL-17 receptor E (IL-17RE) expression in endometriotic cells, to be associated with cancerogenesis and which has no previous association with EAOC. Elevated IL-17C concentration is found in peritoneal fluid in women with ovarian cancer and IL-17RE-overexpressed endometriosis mice. In particular, IL-17C knockout reduces peritoneal fluid IL-17C concentration and inhibits ectopic lesion growth in endometriosis mice. Besides, the role of IL-17C in the endometriosis cancerogenesis was investigated by blocking the IL-17C/IL-17RE, modulating IL-17RE and neutralizing IL-17C in endometriotic cells, endometrial organoids and endometriosis mice. These data defined peritoneal fluid-mediated endometriosis cancerogenesis through IL-17C regulation and suggests that IL-17C/IL-17RE can thus potentially serve as novel targets for with high IL-17C.

Project description:Transcriptional profiling in peritoneal adipose tissue of 48 pigs (132 days of age) originated from two lines divergently selected for residual feed intake (RFI) : low-RFI pigs (RFIneg), high-RFI pigs (RFIpl). Both lines were offered isocaloric and isoproteic diets with contrasted energy source and nutrients: low fat, low fiber (LF) diet or a high fat, high fiber (HF)diet during 10 weeks. Effects of RFI selection, diet and interaction between diet and line were investigated.

Effects of RFI selection, diet and interaction between diet and line were investigated. Four experimental groups: low-RFI pigs fed high fat, high fiber diet (HF_RFIneg), high-RFI pigs fed high fat, high fiber diet(HF_RFIpl), low-RFI pigs fed low fat, low fiber diet (LF_RFIneg) and high-RFI pigs fed low fat, low fiber diet(LF_RFIpl). 12 pigs per condition. One replicate per array.

Project description:Endometriosis is a common gynecological disease of women in reproductive age, and is primarily thought to arise from retrograde menstruation and implantation of endometrium, mostly into the peritoneal cavity. The condition is characterized by a chronic, unresolved inflammatory process, within which oxidative stress likely plays a critical role. Although elevated reactive oxygen species (ROS) and oxidative stress have previously been postulated as being involved in endometriosis pathogenesis, we set out for a more systematic study to identify novel factors defining oxidative stress in ectopic peritoneal lesions. Using combined proteomic and transcriptomic approaches, we identified novel targets, including upregulated pro-oxidative enzymes such as amine oxidase 3/vascular adhesion protein 1 (AOC3/VAP1), as well as downregulated protective factors such as alkenal reductase PTGR1 or methionine sulfoxide reductase, supporting the observation of increased oxidative protein modification in ectopic lesions and peritoneal fluid. The observed ROS-derived 4-hydroxy-2-nonenal-induced interleukin (IL)-8 release from monocytes indicates a further pathomechanism, whereby elevated IL-8 levels promote further immune cell infiltration and angiogenesis in lesions.

Project description:A number of studies have proposed that excess food intake, particularly of high fat diets arise due dysregulation of homeostatic mechanisms regulating neuroendocrine control of appetite and energy balance. Current dogma suggests high fat diets invoke hypothalamic inflammation which reduces hypothalamic sensitivity to metabolic and hormonal cues of conveying peripheral status of energy balance, such as leptin and insulin. A hypothesis for the mechanism leading to hypothalamic inflammation is based on high fat diet mediated changes in gut microbiota which are then proposed to increase circulating levels of lipopolysaccharide (LPS). This in turn activates a hypothalamic inflammatory response via the toll-like receptor (TLR4) and CD14. The aim of this study was to determine hypothalamic gene expression in response to long term feeding of a high fat diet, taking into account the importance of using a control diet with a similar composition and balanced for sucrose content.

Project description:Dietary lipids and gut microbiota may both influence adipose tissue physiology. By feeding conventional and germ-free mice high fat diets with different lipid compositon we aimed to investigate how dietary lipids and the gut microbiota interact to influence inflammation and metabolism in the liver Wild-type C57Bl/6 male mice 11 weeks of age were fed isocaloric diets (45% kcal fat) with either menhaden fish oil (Research Diets, D05122102) or lard (Research Diets, D10011202) for 11 weeks. Liver samples were harvested at the end of the experiment and analyzed by microarray.
