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. Gene expression measurements implicate TRPA1 as the heat-sensitive channel in diverse pit snakes

Project description:This study aims to analyze and compare the post-translational modification differences between human plasma- and genetic recombination-derived human serum albumin (HSA) in clinical treatments in China. 6 different post-translational modifications, including acetylation, succinylation, crotonylation, phosphorylation, beta-hydroxybutyrylation, and lactylation, were detected using pan-specific antibodies through Western blot. The samples, consisting of human plasma-derived HSA (pHSA) from six different manufacturers and recombinant HSA (rHSA) expressed in yeast and oryza sativa, underwent detection of types of post-translational modifications. 4D label-free PTMs quantitative proteomic analysis was conducted to detect N-glycosylation and the above-mentioned post-translational modifications in pHSA and rHSA samples, and analyze the differences in modification sites and levels. Through Western blot analysis, all six pHSA and two rHSA samples were positive in the band of albumin (66.5 kDa) for the six post-translational modifications. Further analysis using 4D label-free PTMs quantitative proteomics revealed 25 (29) acetylated, 30 (32) succinylated, 41 (50) malonylated, 15 (23) phosphorylated, 36 (30) beta-hydroxybutyrylated, and 27 (34) lactylated modification sites in pHSA and rHSA samples and no N-glycosylation modification sites. The analysis results identified 1 acetylation (ALB_K160), 2 beta-hydroxybutyrylation (ALB_K569, ALB_K426), 3 crotonylation (ALB_K264, ALB_K581, ALB_K560), and 15 phosphorylation specific modification sites in pHSA, as well as 3 crotonylation (ALB_K560, ALB_K562, ALB_K75), 1 succinylation (ALB_K490), and 23 phosphorylation specific modification sites in rHSA. In pHSA (rHSA), 2 (6) acetylation, 10 (12) succinylation, 0 (9) crotonylation, 1 (9) phosphorylation, 6 (0) beta-hydroxybutyrylation, and 0 (7) lactylation specific modification sites were found. Additionally, in the common modification sites of pHSA and rHSA, pHSA showed up-regulation of amberylation (16:1) and beta-hydroxybutyrylation (12:2) in more sites, and up-regulation of acetylation (7:11), crotonylation (2:11), phosphorylation (1:8), and lactylation (1:14) in less sites compared to rHSA. In clinical treatment, the used pHSA and rHSA in China generally exhibit acetylation, succinylation, crotonylation, phosphorylation, beta-hydroxybutyrylation, and lactylation, and there are differences in the site characteristics and modification levels of these modifications between pHSA and rHSA. Further experimental investigations are needed to explore the impact of post-translational modification differences on the biological function, efficacy, and safety of pHSA and rHSA.

Project description:Migrasomes are newly discovered cell organelles forming by local swelling of retraction fibers. The migrasome formation critically depends on tetraspanin proteins present in the retraction fiber membranes and is modulated by the membrane tension and bending rigidity. It remained unknown how and in which time sequence these factors are involved in migrasome nucleation, growth, and stabilization, and what are the possible intermediate stages of migrasome biogenesis. Here using live cell imaging and biomimetic system for migrasomes and retraction fibers, we reveal that migrasome formation is a two-stage process. At the first stage, which in biomimetic system is mediated by membrane tension, local swellings largely devoid of tetraspanin 4 form on the retraction fibers. At the second stage, tetraspanin 4 molecules migrate toward and onto these swellings, which grow up to several microns in size and transform into migrasomes. This tetraspanin 4 recruitment to the swellings is essential for migrasome growth and stabilization. Based on these findings we propose that the major role of tetraspanin proteins is in stabilizing the migrasome structure while the migrasome nucleation and initial growth stages can be driven by membrane mechanical stresses.

Project description:Background In broilers, heat stress can result in reduced feed consumption, digestive inefficiency, impaired metabolism, and even death. The broiler sector of the U.S. poultry industry incurs approximately $52 million in heat stress-related losses annually. The objective of this study is to characterize the effects of chronic, cyclic heat stress on the transcriptome of a metabolically active organ, the liver. Characterizing the liver transcriptome of heat-stressed broilers will help clarify the effects of heat stress on metabolism. This information will provide a platform for future investigations that further elucidate physiologic responses to heat stress and seek methods to ameliorate the negative impacts of heat. Results Transcriptome sequencing of the livers of 8 broiler males using Illumina HiSeq 2000 technology, resulted in a total of 138 million, 100 base pair single end reads, yielding 13.8 gigabases of sequence. Forty genes were differentially expressed at a significance level of P-value < 0.05 and a fold change ≥ 2 in response to chronic, cyclic heat stress (mid-point of the last day of a 7-day cyclic heat stress of 7 hours per day), with 27 down-regulated and 13 up-regulated. Two gene networks were created from the function-based Ingenuity Pathway Analysis (IPA) of the differentially expressed genes; “Cell Signaling, Molecular Transport, Small Molecule Biochemistry” and “Endocrine System Development and Function, Small Molecule Biochemistry Cell Signaling”. Members of the MAPK signaling pathway and differentially expressed genes that are associated with MAPK-related functions were prominent in the networks. Cellular proliferation and differentiation, inflammationand stress-related signaling, and apoptosis-associated genes were down-regulated in response to heat stress. Genes responsible for inhibiting feed intake and sphingolipidrelated signaling were up-regulated. Genes involved with the regulation of inflammation, stress, thyroid hormone level, and body temperature were both up- and down-regulated. Conclusions Chronic, cyclic heat stress of broilers results in metabolic changes that can be characterized through RNA-seq analysis of the liver transcriptome. The primary affected pathways included cell signaling, molecular transport, endocrine system development and signaling, and small molecule biochemistry. Examination of 2 heat treatments. Four heat stressed liver samples and 4 control liver samples analyzed.
