Project description:Snakes possess a unique sensory system for detecting infrared radiation, enabling them to generate a ‘thermal image’ of predators or prey. Infrared signals are initially received by the pit organ, a highly specialized facial structure that is innervated by nerve fibers of the somatosensory system. How this organ detects and transduces infrared signals into nerve impulses is not known. Here we use an unbiased transcriptional profiling approach to identify TRPA1 as the infrared receptor on sensory neurons that innervate the pit organ. TRPA1 from pit bearing snakes (rattlesnakes and pythons) are the most heat sensitive vertebrate ion channels thus far identified, consistent with their role as primary transducers of infrared stimuli in these animals. Thus, snakes detect infrared signals through a mechanism involving radiant heating of the pit organ, rather than photochemical transduction. These findings illustrate the broad evolutionary tuning of TRP channels as thermosensors in the vertebrate nervous system.

Project description:Decreased mineral density is a risk factor for skeletal pathologies including bone metastasis, the leading cause of mortality in patients with advanced breast cancer, but the underlying mechanisms are poorly understood. While reduced mineral density can drive pathological bone remodeling via direct effects on select cell types, indirect effects due to broad changes of the microenvironment may be similarly important. However, how bone mineral content affects microenvironmental heterogeneity remains to be elucidated. Here, we leverage decellularized bone matrices with varied mineral content in combination with single-cell RNA-sequencing to study how reduced bone mineral content affects microenvironmental complexity and tumor growth. We performed single-cell RNA sequencing on implanted decellularized bovine bone scaffolds in which the mineral was either maintained at physiological levels or removed to simulate scenarios of impaired bone mineralization as, for example, present during aging. Using this approach, we explored the heterogeneous stromal response to varied bone mineral content in both an immunocompromised and immunocompetent, syngeneic mouse model in the presence and absence of cancer cells.

Project description:Cell lysates of Fusarium sp. DS 682, a saprotrophic fungus, were prepared from fungal biomass grown on PDA agar without M9 and micronutrients. Fungus was exposed to minerals, 100 uL of 50% (w/v) natural kaolinite solution. Three fungal plate collections for each growth condition, with (+ mineral) and without mineral (- mineral), were grown for 14 days on PDA (incubated at 28 C) and harvested after 15 days. Extracted hyphae (500 mg) was prepared using the MPLEx protocol. A nanoACQUITY ultra performance liquid chromatography (LC) with a 2DLC system was used for separation of protein digests. Eluted peptides from the C18 column were analyzed using a Q-Exactive Plus Orbitrap MS for high resolution MS and high-energy collision-induced dissociation tandem MS by electrospray ionization for subsequent quantitative proteomic analysis. Data was searched with MaxQuant. Additional post-processed results and metadata can be accessed at https://doi.org/10.25584/KSOmicsFspDS682/1766303

Project description:Vampire bats and snakes have taken thermosensation to the extreme by developing specialized systems for detecting infrared radiation. As such, these creatures provide a window into the molecular and genetic mechanisms underlying evolutionary tuning of thermoreceptors in a species or cell type specific manner. In each case, robust thermal sensitivity likely reflects specialized anatomical features of infrared sensing pit organs, as well as intrinsic heat sensitivity of trigeminal nerve fibers that innervate these structures. Here we show that vampire bats use a molecular strategy involving alternative splicing of the TRPV1 gene to generate a channel specifically within trigeminal ganglia that has a reduced thermal activation threshold. Selective expression of splicing factors in trigeminal, but not dorsal root ganglia, together with unique organization of the vampire bat TRPV1 gene underlies this mechanism of sensory adaptation. Comparative genomic analysis of the TRPV1 locus supports phylogenetic relationships within the proposed Pegasoferae clade of mammals. Gene expression measurements implicate a TRPV1 splice isoform as the heat-sensitive channel in vampire bats

Project description:Concerning the roles of LCN2 in chronic inflammation and fibrosis, we investigated chronic liver inflammation and fibrosis using repeated carbon tetrachloride (CCl4) in mineral oil injection. We found that mice treated with the mineral oil vehicle alone also showed liver inflammation and more severe in wild-type mice compared to lipocalin 2 null mice.

Project description:Proton toxicity is one of the major environmental stresses limiting crop production, and becomes increasingly serious because of anthropogenic activities. To understand acid tolerance mechanisms, the plant growth, mineral nutrient accumulation and global transcriptome changes in soybean (Glycine max) in response to long-term acid stress were investigated. Results showed that acid stress significantly inhibited soybean root growth, but exhibited slight effects on the shoot growth. Moreover, concentrations of essential mineral nutrients were significantly affected by acid stress, mainly dependent on soybean organs and mineral nutrient types. The concentrations of phosphorus (P) and molybdenum (Mo) in both leaves and roots, nitrogen (N) and potassium (K) in roots and magnesium (Mg) in leaves were significantly decreased, respectively. Whereas, the concentrations of calcium (Ca), sulfate (S) and iron (Fe) were increased in both leaves and roots. Transcriptome analyses in soybean roots resulted in identifying 419 up-regulated and 555 down-regulated genes under acid conditions. A total of 38 differentially expressed genes (DEGs) were involved in mineral nutrient transportation. Among them, all the detected five GmPTs and GmZIPs, two GmAMTs and GmKUP genes, together with GmIRT1, GmNramp5, GmVIT2.1, GmSKOR, GmTPK5 and GmHKT1, were significantly suppressed. Moreover, the genes encoding transcription factors (e.g., GmSTOP2s and a GmPHL1), and genes involved in pH stat metabolic pathways were significantly up-regulated by low pH stress in soybean roots. Taken together, it strongly suggested that maintaining pH stat and mineral nutrient homeostasis are adaptive strategies of soybean responses to acid stress, which might be regulated by a complex signaling network.
