Project description:Systemic acute inflammatory signals can cause profound anorexia by disrupting the physiological appetite regulation in the hypothalamic milieu. Conversely, obesity related chronic inflammation of the hypothalamus can disturb anorexigenic signals and promote abnormal body weight control. The aim of the present study was to compare the global hypothalamic endophenotype in C57/Bl6 mice exposed to a high-fat diet or with acute illness mediated by LPS. Ten-week old male C57/Bl6 mice (n=18) were randomly divided into four groups; the control 1 group (n =3) was fed a normal diet whereas the high-fat diet (HFD) group (n =6) was fed a high-fat diet for eight weeks. The control 2 group (n=3) received an intraperitoneal injection of saline whereas the LPS group (n=6) received an intraperitoneal injection of LPS. Mice were sacrificed 18-hr post-injection. Both control 2 and LPS groups were fed a normal diet for eight weeks before the injection. The hypothalamic regions were removed and analysed using a 2D LC-MS methodology. The proteomic analysis profiled 9,235 proteins (q<0.05) across all biological states, of which 522 proteins were found modulated in the HFD group and another 579 in the LPS group. The proteomic profiles demonstrated that the systemic acute inflammation linked with anorexia induced a negative feedback loop of appetite control in the hypothalamus, suggesting an effort to re-establish homeostasis. By contrast, the chronic inflammation associated with obesity initiated a “perpetual cycle” of positive feedback enhancement of appetite regulation further exacerbating positive energy balance.

Project description:In this study, human particulated dentin (HPD) was developed. The characteristic of HPD was examinated by XRD, EDX and cytotoxicity test. HPD was used to implant in the calvarial defects of New Zealand White rabbits. bone tissue and blood samples were taken at 3, 5 and 7 days post-implantation for microarray experiment. The gene expression profiles and signaling pathways were monitored using GeneSpring software and Ingenuity Pathways Analysis (IPA), respectively. We used microarray and IPA to elucidate the global programme of gene expression and identified distinct classes of up- and down- regulated genes during HPD treated healing process.

Project description:Pomegranate skin extract could prevent fatty liver due to high fat diet in adult male Sprague Dawley rat. There are 3 groups of rats, feeding chow diet, high fat diet and high fat diet combined with pomegrante skin extract. After 8 weeks feeding, high fat diet group developped fatty liver but the other two groups still have healthy liver. We used microarrays to detail the global programme of gene expression underlying the fatty liver development and preventive effect of pomegranate skin extract on fatty liver. There are 3 treatment groups and 6 replicates for each group. The 3 treatment groups are control group feeding chow diet, high fat group feeding high fat diet and PE group feeding high fat diet and pomegranate skin extract. Rat livers were collecteded for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Global gene expression in the 20-week remnant kidneys of uninephrectomized mice fed either a chow or a high fat diet was compared with kidney tissue from the corresponding sham groups. Results provide insight into mechanisms underlying effects of high-fat induced obesity on gene expression in mouse kidney. Male C57/BJ mice aged 6 weeks were randomly assigned to uninephrectomy (UNX) or sham procedures and fed with a high fat diet or control chow diet. All mice were sacrificed under anesthesia 20 weeks after surgery and kidneys were harvested. 3-4 total RNA samples per group were analyzed and gene expression was compared between groups.

Project description:The prevalence of obesity has significantly increased worldwide. Therefore, this study aimed to evaluate the influence of obesity in the proteomic profile of periodontal ligament (PDL) tissues of rat first maxillary molars submitted to orthodontic tooth movement. The study was approved by the Ethical Committee on Animal Experimentation of the Sao Paulo State University, School of Dentistry at Araraquara, Brazil (protocol number 16/2015) and followed the Animal Research: Reporting of In Vivo Experiments guidelines. Therefore, for this study, we used ten male adult Holtzman rats (weight average – 300 g, approximately 8 weeks old). Animals were randomly assigned to one of the following experimental groups: 1 – M group: animals received a standard diet and 75 days after that, the first maxillary molar was randomly selected to be submitted to OTM for 15 days (n=5), and 2 – OM group: animals received a high-fat diet to induce obesity, and 75 days after that the first maxillary molar was randomly selected to be subjected to OTM for 15 days (n=5). All animals were kept under controlled temperature (22-25 °C), receiving water ad libitum with a 12-hour light/dark cycle. To induce obesity, animals of the OM group received a high-fat diet. In contrast to the standard diet (Labina/Purina, Ribeirão Preto, Brazil) administered to the M group. The high-fat diet contained around 3.82 kcal/g and was composed of 27.5 % of standard rat chow plus 25 % of peanuts, 25 % of milk chocolate, and 12.5 % sweet biscuits and contained 20 g of protein, 48 g of carbohydrate, 20 g of total fat, and 4 g of fiber per 100 g of diet. This feed was daily replaced and had started 75 days before baseline (M initiation). The procedure to induce OTM was by a closed coil nickel-titanium spring (Sentalloy, GAC Central Slip, New York, EUA) connected the maxillary first molar and central incisors with a steel wire (CrNi, 0.20 mm, 55.01.208; Morelli, Sorocaba, Brazi). Fifteen days after OTM, animals were euthanized by anesthetic overdose.

Project description:To profile the expression of circulating miRNAs in a mouse model of diet-induced obesity (DIO) with subsequent weight-reduction with low-fat diet (LFD), eighteen C57BL/6 male mice were grouped into three subgroups as: (1) Control: the mice fed with the standard AIN-76A (fat: 11.5 kcal%) diet for 12 wks; (2) DIO: the mice fed with 58 kcal% high-fat diet for 12 wks; (3) DIO+LFD: the mice fed with high-fat diet for 8 wks to induce obesity, then changed to 10.5 kcal% low-fat diet for subsequent 4 wks. C57BL/6 mice were purchased from BioLasco (Taipei, Taiwan). All housing conditions were maintained, and surgical procedures, including analgesia, were performed in an Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC)-accredited SPF facility according to national and institutional guidelines. In this experiment, eighteen C57BL/6 wild type male mice were randomly grouped into three subgroups (n=6 in each group): (1) Control: the control mice were fed ad libitum a standard AIN-76A (fat: 11.5 kcal%) diet for 12 wks; (2) DIO: the mice were fed ad libitum a 58 kcal% HFD (D12331; Research Diets Inc., New Brunswick, NJ) for 12 wks to induce obesity; (3) DIO+LFD: the mice fed ad libitum a 58 kcal% HFD (D12331) for 8 wks to induce obesity, then continued the feeding of 10.5 kcal% LFD (D 12329; Research Diets Inc.) for additional 4 wks. Weight measurements were performed on a weekly basis to for these three groups of mice. Evaluation of blood glucose levels was performed at the beginning and in the end of the experiment to confirm that the HFD-fed mice developed an obese and insulin resistant phenotype. After the end of experiment at 12w, all mice were killed. The abdominal WAT of each mice was removed and weighted. Paraffin-embedded abdominal WAT was sectioned at 5 M-NM-<m and stained with hematoxylin and eosin to measure mean adipocyte area. A volume of 1 mL of whole blood was collected into a plain tube and allowed to clot for 1 hour. The sera samples were aliquoted after centrifugation at 3,000 M-CM-^W g for 10 minutes and stored at M-bM-^HM-^R80M-BM-0C until further analysis.
