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.

Project description:High sugar consumption, as well as high-fat diet, is a known cause of obesity and metabolic syndrome. However, the synergistic effect of high-sugar and high-fat consumption rarely has been evaluated, especially in terms of transcriptional regulation. Therefore, we focused on the effect of high sugar consumption on hepatic transcriptional networks in normal and high fat-fed mice. C57BL/6J mice were divided into four groups and were provided either 23%(w/v) sugar solution or plain water with either high-fat or normal-fat diet for 10 weeks. As a result, high sugar consumption significantly altered lipid metabolism-related genes in normal fat-fed mice; however, in high fat-fed mice, high sugar consumption altered inflammation-responsive genes rather than lipid metabolism. After all, these modulations eventually increased lipid accumulation in the liver and caused systemic metabolic disturbances. These observations for the first time suggested that high sugar consumption along with high-fat diet could lead to the development of severe metabolic syndrome via altering hepatic transcriptional networks.

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.

Project description:Purpose: NGS was used to determine if a distinct transcriptomic profile is observed among the experimental mice fed four different dietary components. Methods: We carried out RNA-Seq analysis of ileum tissue from 6 weeks male mice ad libitum fed for 10 weeks a high liquid sugar (23% (w/v)) or/and high fat (60% Kcal from fat) diet. The combined effect of sugar drink and high fat diet (HF-Sugar) was compared with sugar drink only (NF-Sugar), or high fat diet only (HF), or control diet that was plain water and normal fat diet (NF). Results: RNA-Seq revealed sample-specific clusters that included genes responding to each experimental diet. We found only addition of sugar drink to high fat group (HF-Sugar) not NF-Sugar and HF, there was a significant enrichment in biological functions relating to Inflammatory/Immune Responses, especially including dendritic cell (DC) and T cell related signaling pathway. Conclusions: Taken together, our data demonstrate that sugar drink synergistically promotes and exacerbates inflammatory responses driven by the high fat diet.

Project description: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.

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.

Project description:Cassava’s storage roots represent one of the most important sources of nutritional carbohydrates worldwide. Particularly, smallholder farmers in Sub-Saharan Africa depend on this crop plant, where resilient and yield-improved varieties are of vital importance to support steadily increasing populations. Aided by a growing understanding of the plant’s metabolism and physiology, targeted improvement concepts already led to visible gains in recent years. To expand our knowledge and to contribute to these successes, we investigated storage roots of eight cassava genotypes with differential dry matter content from three successive field trials for their proteomic and metabolic profiles. At large, the metabolic focus in storage roots transitioned from cellular growth processes towards carbohydrate and nitrogen storage with increasing dry matter content. This is reflected in higher abundance of proteins related to nucleotide synthesis, protein turnover and vacuolar energization in low starch genotypes, while proteins involved in sugar conversion and glycolysis were more prevalent in high dry matter genotypes. This shift in metabolic orientation was underlined by a clear transition from oxidative- to substrate-level phosphorylation in high dry matter genotypes. Our analyses highlight metabolic patterns that are consistently and quantitatively associated with high dry matter accumulation in cassava storage roots, providing fundamental understandings of cassava’s metabolism as well as a data resource for targeted genetic improvement.

Project description:Salt stress is a major abiotic stress that limits plant growth, development and productivity. Studying the molecular mechanisms of salt stress tolerance may help to enhance crop productivity. Sugar beet monosomic addition line M14 exhibits tolerance to salt stress. In this work, the changes in the BvM14 proteome and redox proteome induced by salt stress were analyzed using a multiplex iodoTMTRAQ double labeling quantitative proteomics approach. A total of 80 proteins were differentially expressed under salt stress. Interestingly, 42 potential redox-regulated proteins showed differential redox change under salt stress. A large proportion of the redox proteins were involved in photosynthesis, ROS homeostasis and other pathways. For example, ribulose bisphosphate carboxylase/oxygenase activase changed in its redox state after salt treatments. In addition, three redox proteins involved in regulation of ROS homeostasis were also changed in redox states. Transcription levels of eighteen differential proteins and redox proteins were profiled. The results showed involvement of protein redox modifications in BvM14 salt stress response and revealed the short-term salt responsive mechanisms. The knowledge may inform marker-based breeding effort of sugar beet and other crops for stress resilience and high yield.
