Proteomic analysis of digestive fluids of Thermobia domestica

ABSTRACT: Digestive fluids isolated from the foregut (crop) of adult specimens of T. domestica were analysed by shotgun proteomics in order to identify the putative carbohydrate-active enzymes involved in plant cell wall digestion.

Thermobia domestica belongs to an ancient group of insects and has a remarkable ability to digest crystalline cellulose without microbial assistance. By investigating the digestive proteome of Thermobia, we have identified over 20 members of an uncharacterized family of lytic polysaccharide monooxygenases (LPMOs). We show that this LPMO family spans across several clades of the Tree of Life, is of ancient origin, and was recruited by early arthropods with possible roles in remodeling endogenous ...[more]

TGF β signaling functions as a sugar sensing feedback loop to regulate digestive enzyme expression.

Project description:Organisms need to assess their nutritional state and adapt their digestive capacity to the demands for various nutrients. Modulation of digestive enzyme production represents a potential step to regulate nutriment intake. However, the role of digestion in nutrient homeostasis has been largely neglected. In this study, we analyzed the mechanism underlying glucose repression of amylase in the adult Drosophila midgut. We demonstrated that glucose represses many carbohydrases and lipases. Our data shows that the consumption of nutritious sugars stimulates the secretion of the TGFβ ligand, Dawdle. Dawdle then acts via the circulation to activate TGFβ/Activin signaling in the midgut, culminating in the repression of digestive enzyme expression. Thus, our study not only identifies a mechanism coupling sugar sensing to digestive enzyme expression but points to an important role of TGFβ/Activin signaling in sugar metabolism. RNA-sequencing of whole guts from Drosophila melannogaster OregonR adult females was performed under three feeding conditions: Standard medium, glucose, and agar. Three biological repeats were performed for each condition.

Transforming growth factor β/activin signaling functions as a sugar-sensing feedback loop to regulate digestive enzyme expression.

Project description:Organisms need to assess their nutritional state and adapt their digestive capacity to the demands for various nutrients. Modulation of digestive enzyme production represents a rational step to regulate nutriment uptake. However, the role of digestion in nutrient homeostasis has been largely neglected. In this study, we analyzed the mechanism underlying glucose repression of digestive enzymes in the adult Drosophila midgut. We demonstrate that glucose represses the expression of many carbohydrases and lipases. Our data reveal that the consumption of nutritious sugars stimulates the secretion of the transforming growth factor β (TGF-β) ligand, Dawdle, from the fat body. Dawdle then acts via circulation to activate TGF-β/Activin signaling in the midgut, culminating in the repression of digestive enzymes that are highly expressed during starvation. Thus, our study not only identifies a mechanism that couples sugar sensing with digestive enzyme expression but points to an important role of TGF-β/Activin signaling in sugar metabolism.

Genome-wide methylation profiles of forensically relevant body fluids [Set3]

Project description:The ability to predict tissue type and donor’s age from molecular profiles of crime scene samples has practical implications in forensics. In order to identify body fluid- and age-associated DNA methylation changes, genome-wide DNA methylation profiling was carried out for body fluids including blood, saliva, semen, menstrual blood, and vaginal fluid obtained from individuals aged 20 to 59. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in bisulfite converted DNA. Samples included 12 of each blood, saliva and semen samples from 18 male donors aged 20 to 59, and 3 of each vaginal fluid and menstrual blood samples from 4 female donors in their twenties. Genome-wide DNA methylation profiling of body fluids obtained from individuals aged 29 to 41. The Illumina Infinium 450K Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 450K CpGs from human body fluids including blood, saliva and semen. Bisulfite converted DNA from the 6 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip
