Expression data from adult wild-type male Drosophila melanogaster fed control or high-sugar diets

ABSTRACT: Chronic high-sugar feeding (1 M or 34% sucrose) leads to hyperglycemia, obesity, and insulin resistance in adult flies, compared with those fed a control diet (0.15 M or 5% sucrose). We compared two days and four weeks of high-sugar feeding to look at short- and long- term effects on gene expression. We used Affymetrix Drosophila GeneChip 2.0 microarrays to quantify differential expression between control and high-sugar-fed flies at two time points.

Expression data from control and high sugar-fed third instar Drosophila larvae

Project description:Chronic high sugar feeding induces obesity, hyperglycemia, and insulin resistance in flies and mammals. To gain insight into the mechanisms underlying this response, we profiled gene expression in chronically high sugar fed, wandering (post-prandial) third instar wild type larvae (L3). These data were compared to control-fed larvae as well as those (mid-L3) actively feeding for twelve hours on both diets. We used microarrays to detail the response of Drosophila larvae to high sugar-induced insulin resistance. Male Canton-S third instar larvae were fed control (0.15M) or high (1M) sucrose and selected for RNA extraction and hybridization on Affymetrix microarrays. Wandering L3 were selected as those in the top half of the vial with partial blue guts to confirm that they had stopped eating the (blue) food. Mid-L3 were selected as L2, aged overnight until early L3, then transferred to fresh control or high sucrose food for 12 more hours before selection.

Expression data from 0.15M and 0.7M-fed wild-type and ChREBP mutant, third instar Drosophila larval fat bodies (FBs)

Project description:Chronic high sugar feeding induces obesity, hyperglycemia, and insulin resistance in flies and mammals. These phenotypes are controlled by the fat body, a liver- and adipose- like tissue in Drosophila flies. To gain insight into the mechanisms underlying the connection between diet and insulin sensitivity, we used Illumina RNA-seq to profile gene expression in fat bodies isolated from chronically high sugar fed, wandering (post-prandial) third instar wild type larvae w(L3). These data were compared to control-fed wild-type wL3 fat bodies as well as those expressing transgenic interfering RNA (i) targeting CG18362 (Mio/dChREBP) in the fat body on both diets. Female VDRC w1118, cgGAL4, UAS-Dcr2 or UAS-ChREBPi(52606), cgGAL4, UAS-Dcr2 wandering third instar larvae were fed control (0.15M) or high (0.7M) sucrose and fat bodies isolated for RNA extraction.

Expression data from third instar Drosophila larvae offspring from maternal control or high-sucrose fed diets

Project description:Maternal obesity and diabetes is associated with increased risk of obesity and diabetes in offspring. We generated a model of maternal caloric excess in Drosophila and noted altered body composition in offspring from females fed a high-sucrose diet. To gain insight into the mechanisms underlying this response, we profiled gene expression in mid-third instar larvae (mid-L3) offspring from either control or high-sucrose fed females. All offspring were raised on control food. We used microarrays to detail the response of Drosophila larvae to maternal high calorie diet Virgin female w1118 flies were fed control (0.15M) or high (1M) sucrose food for 7 days, mated with male w1118 flies such that all embryos were laid on control food. Mid-L3 larvae were selected for RNA extraction and hybridization on Affymetrix microarrays. Mid-L3 were selected as L2, aged overnight until early L3, then transferred to fresh control food for 12 more hours before selection.

Differentially expressed genes in the fly brain under condtions of sugar and complete starvation

Project description:In order to study the transcriptional response of the fly brain to sugar and complete starvation, we first confirmed that 24 hours of sugar and complete starvation in flies is sufficient to elicit a homeostatic response. Subsequently, we used holidic medium to study effects of deficiency of a specfic macronutrient- cabohydrate in the food. To do so , we generated RNA- seq libraries from brains of 5 day old mated adult male flies maintained on different feeding regimes and used the sequencing data to identify diffrentially expressed genes in the brain under different feeding regimes.

Nutritional programming of lifespan: Excessive sugar consumption in early adulthood curtails Drosophila survival by inhibiting dFOXO

Project description:Fruit flies were maintained either 40% sugar or 5% sugar diets for one week, then on 5% sugar for one further week. Whole flies were sampled at the end of weeks 1 and week 2. Persistent effects of past high sugar diets are identified.

Effect of EcR RNAi on wandering third instar larval fat body gene expression in Drosophila melanogaster

Project description:We compared ecdysone receptor (EcR)-dependent gene expression in the Drosophila fat body on 0.15 M sucrose and 0.5 M sucrose high-sugar diets in order to gain insight into the role of this gene during caloric overload. Phenotypic analyses showed an increased severity of EcR RNAi phenotypes with increasing dietary sugar concentration. Because EcR is a transcription factor, we performed RNA-seq studies to identify transcriptional targets that might underlie insulin resistance downstream of EcR RNAi.

Clockwork orange-mediated control of sugar responsive transcription [ChIP-seq]

Project description:Feeding on high sugar diet reprograms metabolism, partially mediated through a gene regulatory network controlled by intracellular sugar sensor Mondo/ChREBP-Mlx. Sugar-induced gene expression changes include activation of genes encoding enzymes of glycolysis, pentose phosphate pathways, and de novo lipogenesis, collectively driving the flux of sugar-derived carbon into triacylglycerides. These sugar-induced metabolic changes are likely to trigger compensatory responses to avoid depletion of necessary metabolites, but they remain poorly characterized. Through a global temporal clustering analysis of sugar-induced gene expression in Drosophila we identify new gene expression programs controlled by sugar feeding. These include rapid and transient downregulation of ribosome biogenesis genes, known targets of transcription factor Myc. Through in silico motif predictions and experimental validation, we identify transcriptional repressor Clockwork orange (CWO) as a mediator of this response. CWO expression is directly activated by Mondo-Mlx and it counteracts Myc through repression of its expression as well as through binding to overlapping regulatory regions of ribosome biogenesis genes. Loss of CWO function leads to depletion of UDP-GlcNAc pools and impaired viability on high sugar diet. Analysis of CWO orthologs, BHLHE40 and BHLHE41, in mouse hepatocytes revealed a conserved role for BHLHE41 in repressing ribosome biogenesis genes. Collectively, our data uncover a gene regulatory circuit balancing the activities of lipid and protein biosynthesis to maintain homeostasis during high sugar feeding.
