The impact of growing area on the expression of fruit traits re-lated to sensory perception in two tomato cultivars

Project description:The environmental conditions greatly influence tomato fruit quality, by affecting the expression of genes, the abundance of metabolites and the perception of sensorial attributes.In this study, a fruit transcriptome investigation, together with a sensory test and a metabolomic analysis were per-formed to evaluate the impact of the environment on two popular tomato cultivars grown in two Italian regions. The transcriptional profile of each cultivar, cultivated in two different areas high-lighted differential expression in genes involved in pathways related to cell wall components such as pectin, lignin and hemicellulose, sugars as well as in amino acids, phenylpropanoids, and pigment synthesis. The cultivation area mainly affects sensory attributes related to texture and flavor and the metabolic pattern of cell wall precursors, sugars, glutamate, aspartate and carotenoids. In the two genotypes cultivated in the same environment, some attributes and fruit-related quality processes are similarly affected, while others are differently influenced based on tomato specific genetic makeup. Combination of transcriptomic, sensory and metabolomic data obtained from the two tomato genotypes revealed that the environment has a profound effect on specific sensory traits, providing information on factors that shape the specific characteristics and genetic targets for im-proving tomato fruit characteristics.

Sensory Food Perception Rapidly Primes Postprandial ER-Homeostasis through Melanorcortin-Dependent Control of Liver mTOR Activation

Project description:Adaptation of liver to the postprandial state requires coordinate regulation of protein synthesis and folding aligned with changes in lipid metabolism. Here we demonstrate that sensory food perception is sufficient to elicit early activation of hepatic mTOR-signaling, Xbp1-splicing, increased expression of ER-stress genes and phosphatidylcholine synthesis, which translate into a rapid morphological ER-remodeling. These responses overlap with those activated during refeeding, where they are maintained and constantly increase upon nutrient supply. Sensory food perception activates POMC-neurons in the hypothalamus, optogenetic activation of POMC-neurons activates hepatic mTOR-signaling and Xbp1-splicing and lack of MC4R-expression attenuates these responses to sensory food perception. Chemogenetic POMC-neuron activation promotes sympathetic nerve activity (SNA) subserving the liver, and norepinephrine evokes the same responses in hepatocytes in vitro and liver in vivo as observed upon sensory food perception. Collectively, our experiments unravel that sensory food perception coordinatly primes postprandrial liver ER adaption through a melanocortin-SNA-mTOR-Xbp1s-axis

Olfactory sensory neuron-specific IGF1R knockout in mice results in increased smell perception, insulin resistance and adiposity

Project description:Olfaction is fundamental for survival but there is little known about the connection between smell perception and metabolism. In this study we implemented IGF1R knockout mice in the olfactory sensory neurons, by olfactory marker protetin (OMP) Cre specific recombination, and investigated metabolic parameters, smell perception and transcriptome sequencing. We could demonstrate that IGF1R knockout in the olfactory sensory neurons results in enhanced smell perception, insulin resistance under normal chow diet conditions and increased adiposity in mice fed control diet. Transcriptome analysis of the olfactory epithelium revealed differential expression of markers for mature and immature olfactory sensory neurons, being down-regulated and up- regulated respectively, pointing to differentiation-dependent changes that result in increased olfactory perception. Collectively, this study provides evidence that enhanced smell perception can result in insulin resistance and increased adiposity.

Glycogen Metabolism Drives Sensory Activation of Pomc Neurons

Project description:In this study, we aimed at uncovering the molecular mechanisms underlying POMC neuron sensory activation and the mediated behavioral and metabolic processes. Unexpectedly, we found that glycogen metabolism is rapidly engaged in POMC neurons upon sensory food perception. Genetic deletion of glycogen synthase, the sole enzyme able to make glycogen in vivo, in POMC neurons impedes food-related sensory activation while causing impairments in food awareness, short-term food intake and insulin release. These perturbations associate with whole-body metabolic defects, including overweight and insulin resistance, that are exacerbated by high-dense diets or ageing. Collectively, our study identifies glycogen metabolism as an unanticipated mechanistic driver of POMC neuron sensory activation and provides paradigm-shift evidences of the importance of neuronal glycogen for physiology.

Cross-species single-nuclei transcriptome atlas of dorsal root ganglion sensory neurons [humanDRG]

Project description:Sensory neurons of the dorsal root ganglion (DRG) play a crucial role in maintaining tissue homeostasis by sensing and initiating responses to stimuli. While most preclinical studies of DRGs are conducted in rodents, much less is known about the mechanisms of sensory perception in primates. We generated a transcriptome atlas for mouse, guinea pig, cynomolgus monkey, and human DRGs using a framework that implements a common laboratory workflow (i.e sequencing technologies, laboratory protocols, and sample archival methods) and multiple data-integration approaches to generate accurate cross-species mappings of sensory neuron subtypes.
