Phosphoribotrap-based profiling of activated hypothalamic cells during acute high-fat diet (HFD)-feeding

ABSTRACT: To identify novel neurocircuits activated upon short-term HFD feeding, we employed phosphoribotrap-profiling, which allows for the unbiased identification of alterations in neuronal activation via immunoprecipitation of phosphorylated S6 ribosomal protein-tagged ribosomes from hypothalamic extracts of mice exposed to either 3 days of normal chow diet or HFD-feeding. We have analyzed mRNA selectively expressed in hypothalamic cells activated by a either normal chow diet (NCD)-feeding for 3 days or high fat diet (HFD)-feeding for 3 days. 10-week-old male C57/BL6N mice were put either on a normal chow diet or a high fat diet for 3 days. Afterwards, mice were sacrificed by cervical dislocation. The hypothalamus was rapidly dissected using a stainless steel brain matrix and immediately frozen in liquid nitrogen. Hypothalamic tissues were pooled (8 per IP).

Gene expression in the liver, effect of maternal high-fat diet during or prior to pregnancy

Project description:The present study aimed to examine the effect of high-fat diet prior to pregnancy on the liver of mouse offspring. Female C57BL/6J mice were fed a normal chow (15.2% fat by energy) (CTR and CTR-PP groups) or a high-fat chow (31.2% fat by energy) (HFD and HFD-PP groups) for 3−4 weeks and then mated with male C57BL/6J mice fed normal chow. Some mothers continued on the same diet until pups reached 21 days of age (CTR and HFD), and others were fed the different chows from gestational day 0 (CTR-PP and HFD-PP) to determine the effects of a high-fat diet during the pre-pregnancy period in HFD-PP/CTR and HFD/CTR-PP comparisons. RNA sample was taken from liver of 3-week-old mouse prenatally received high-fat diet prior to pregnancy, during pregnancy and lactation, or through prior to and during pregnancy and lactation, while control RNA was taken from control counterpart prenatally received normal diet alone. Comparisons among groups were made by one-color method with normalized data from Cy3 channels for data analysis.

Mouse liver expression additional replicates

Project description:This study sought to interrogate the effects of lipids and lipid metabolites on the hepatic proteome. Protein expression in high-fat diet (HFD) mouse livers vs. livers of normal chow fed (NC) mice were investigated using multiplexed quantitative LC-MS/MS (TMT labeling). This experiment contains additional replicates for normal chow and mice on high-fat diet for 16 weeks.

Genome-wide analysis of gene expression in adipose tissue of female mice after continuous high fat diet feeding

Project description:Analysis of gene expression in adipose tissue of female mice after continuous high fat diet (HFD) feeding for three generations. The hypothesis in this study is that continuous HFD feeding has transgenerational amplification effects to the offspring. Results provide important information on the impacts of over-nutrition over one generation on the offspring, such as transgenerational up-regulated or down-regulated genes. Total RNA was obtained from adipose tissue of the HFD fed mice, including F0, F1 and F2 generations. Normal chow fed mice were used as controls.

Proteomics analysis of insulin sensitive tissues in high fat diet fed mice

Project description:The popularity of high fat foods in modern society has been associated with epidemic of various metabolic diseases characterized by insulin resistance, the pathology of which involves complex interactions between multiple tissues such as liver, skeletal muscle and white adipose tissue (WAT). To uncover the mechanism by which excessive fat impairs insulin sensitivity, we conducted a multi- tissue study by using TMT-based quantitative proteomics. 3-week-old ICR mice were fed with high fat diet (HFD) for 19 weeks to induce insulin resistance. Liver, skeletal muscle and epididymal fat were collected for proteomics screening. Additionally, PRM was used for validating adipose differential proteins. By comparing tissue-specific protein profiles of HFD mice, multi-tissue regulation of glucose and lipid homeostasis and corresponding underlying mechanisms was systematically investigated and characterized. NC: normal birth weight + chow diet; NH: normal birth weight + high fat diet; LC: low birth weight + chow diet; LH: low birth weight + high fat diet.

C/EBP? and PPAR?-specific transcriptional programs in mature adipocytes in vivo

Project description:We took a systematic approach to determine the transcriptional programs that are specifically regulated by C/EBP? in mature white adipocytes of mice on chow diet or high fat diet. The hypothesis tested in the present study was that C/EBP?, as a lipogenic transcription factor, has unique direct targets compared to PPAR?. Our inducible adipocyte specific knockout system allows us to test the direct targets of C/EBP? and PPAR? in adipocytes by short-term C/EBP? or PPAR? elimination in mature adipocytes in vivo. Results indicate that although it has been shown that C/EBP? and PPAR? cross-regulate each other, they have distinct direct responsive targets. Moreover, there are very few C/EBP? specific targets in mice on a chow diet, most of the C/EBP? targets in mature adipocytes are genes modulated by HFD feeding. Total RNA obtained from subcutaneous adipose tissue of Adn-C/EBP?-/- mice on doxycycline chow diet for 3 days, doxycycline high fat diet for 3 days or 1 month and Adn-PPAR?-/- mice on doxycycline chow diet for 3 days, compared to control littermates.

Gene expression of central amygdala of mice

Project description:Purpose: The goals of this study are to screen out the changes of gene expression profile in response to high fat diet, an mRNA-seq was performed in central amygdala Methods: 6-week-old male wild-type mice were fed with high fat diet (HFD, containing 45% fat) or normal chow diet (ND) for 5 months. And then their central amygdala tissues were removed and total RNA was extracted to perform RNA sequencing. Results:The KEGG pathway analysis showed that genes related to neuroactive ligand-receptor interaction and calcium signaling pathway were dramatically upregulated after HFD Conclusions: Our study represents the first detailed analysis of central amygdalar transcriptomes of mice subjected to high fat diet, with biologic replicates, generated by RNA-seq technology. Our results show genes related to neuroactive ligand-receptor interaction and calcium signaling pathway were dramatically upregulated after high fat diet feeding,which hint at the importance of ion channel in central amygdala after high fat feeding.

KKTa_isolated glomeruli

Project description:High dietary fat intake is a major risk factor for the development of obesity, which is frequently associated with diabetes. To identify genes involved in diabetic nephropathy, GeneChip Expression Analysis was employed to survey the glomerular gene expression profile in diabetic KK/Ta mice fed with a high-fat diet (HFD). Isolated glomeruli from three 20-week-old KK/Ta mice fed with HFD (HFD group) or a normal fat diet (Chow group) were dissected. Total RNA was extracted and labeled for hybridization using the Affymetrix GeneChip Mouse Genome 430 2.0 Array. The gene expression profile was compared between the HFD and Chow groups using GeneSpring 7.3.1 software.
