Implantation of a pelvic nerve array in rats Resource Report Resource Website |
James Fallon, Sophie Payne, Janet Keast, Peregrine Osborne | 10.17504/protocols.io.bjvxkn7n | SPARC | A pelvic nerve array is custom designed for implantation onto the pelvic nerve of male rats. This device is used for long-term (recovery) experiments. The device can electrically stimulate the pelvic nerve as well as record electrically evoked or spontaneous neural activity. Previously, we have successfully implanted rats for 2 months with no reports of biological adverse complications or damage sustained to the array. The surgical procedure is performed under anesthesia and should incorporate all local requirements for standards of animal experimentation, including methods of anesthesia, surgical environment, and post-operative monitoring and care. | Bionics Institute, Bionics Institute, University of Melbourne, University of Melbourne | 1 | 2020 | James Fallon, Sophie Payne, Janet Keast, Peregrine Osborne 2020.

RNA Sequencing of Porine Ganglia and brainstem Resource Report Resource Website |
Leah Reznikov | 10.17504/protocols.io.w5sfg6e | SPARC | RNA Sequencing of Porine Ganglia and brainstem Animals. A total of 44 piglets (Yorkshire Landrace breed, 2–3 days of age) were fed commercial milk replacer (Soweena Litter Life) and allowed a 36–48-h acclimation period before interventions began. The University of Florida Animal Care and Use Committee approved all procedures. Procedures were completed in accordance with federal policies and guidelines. A total of 12 piglets were reserved for RNA sequencing experiments (6 male and 6 female). Airway instillation. After acclimation, piglets were anesthetized with 8% SevoThesia (Henry Schein). The piglets’ airways were accessed with a laryngoscope; a laryngotracheal atomizer (MADgic) was passed directly beyond the vocal folds, as previously described to aerosolize either a 500 μl 0.9% saline control or 1% acetic acid in 0.9% saline solution to the airway. This procedure results in widespread distribution of aerosolized solutions throughout the piglet airway, including the lung. Consistent with acid as a cough-evoking stimulus acetic acid induced cough in 90% or greater of the piglets. Nodose ganglia and brain stem isolation. Forty-eight hours after instillations, piglets were euthanized with a 90 mg/kg intravenous Euthasol solution (Henry Schein). Nodose ganglia were carefully dissected using methods that we previously developed. Ganglia were removed, placed in TRIzol, and stored at −80°C until RNA extraction. Any connective tissues, inflammatory cells, satellite cells, or blood cells covering the ganglia were not removed. A region of the brain stem encompassing the nucleus tractus solitarius, nucleus ambiguous, and dorsal motor nucleus was removed. Briefly, a blunt scissor was used to cut through the sagittal suture of the skull post mortem, and the brain was delicately excised. The cerebellum was removed, and the obex was identified. A section of the brain stem encompassing 2 mm rostral and 2 mm caudal to the obex was then removed and placed in RNAlater (Thermo Fisher Scientific). The block was further trimmed to extend 2 mm in depth and 2 mm lateral from the obex, while still submerged in RNAlater. RNA isolation. RNA from thenodose ganglia, and brain stem were isolated using RNeasy Lipid Tissue kit (Qiagen) with optional DNase digestion (Qiagen). RNA concentrations were assessed using a NanoDrop spectrophotometer (Thermo Fisher Scientific). RNA sequencing. RNA concentration was determined on Qubit 2.0 Fluorometer (ThermoFisher/Invitrogen), RNA quality was assessed using the Agilent 2100 Bioanalyzer (Agilent Technologies). Total RNA with 28S/18S > 1 and RNA integrity number (RIN) ≥ 7 were used for RNAseq library construction. RNAseq library were constructed using NEBNext Ultra Directional RNA library prep kit for Illumina (New England Biolabs) following the manufacturer’s recommendations. Briefly, 1,000 ng of total RNA was used for mRNA isolation using NEBNext Ploy(A) mRNA magnetic isolation module (New England Biolabs, cat. no. E7490). RNA library construction was achieved using NEBNext Ultra Directional RNA library prep kit for Illumina (New England Biolabs; cat. no. E7420). Thirty-six barcoded libraries were sized on the bioanalyzer and quantitated by QUBIT. Libraries were pooled in an equimolar ratio and sequenced by Illumina HiSeq 3000 2X100 cycles run for total of six runs (Illumina). RNA library construction was performed at the Interdisciplinary Center for Biotechnology Research (ICBR) Gene Expression & Genotyping Core, University of Florida (UF). HiSeq 3000 sequencing run was performed at the ICBR NextGen DNA Sequencing core, UF. The nodose ganglia and brain stem of three individual piglets for each condition were prepared separately and used. Mapping and differential gene expression. The quality of the RNA-Seq sequence data was first evaluated using FastQC before further downstream analysis. Low-quality sequences were removed, and the poor-quality part of the reads were trimmed using Trimmomatic. Star Aligner was used to map high-quality paired-end reads to Sus scrofa genome, Sscrofa11.1. Expression was obtained using RSEM. The expected read counts and fragments per kilobase of transcript per million-mapped reads (FPKM) were extracted for further analysis. The estimated read counts were taken as input for edgeR to perform differential expression analysis using generalized linear models. The threshold for calling significantly differentially expressed genes was set at FDR 0.05 with the average FPKM for at least one of each comparison group being higher than 0.

High resolution labeling of vagal efferent fibers using Dextran-Biotin with counterstaining Resource Report Resource Website |
Deborah Jaffey, Terry Powley, Jennifer Mcadams, Robert Phillips | 10.17504/protocols.io.2iqgcdw | SPARC | This protocol describes the methods used to trace and enable morphometric quantification of preganglionic efferent neurites in the rat stomach. A mixture of dextran conjugates was injected into the dorsal motor nucleus of the vagal nerve (dmnX) of young adult Sprague-Dawley rats and after a survival period of 19 days for optimal tracer transport, stomachs were removed and processed as whole mounts. ABC-DAB was used to create a permanent gold-brown stain of all labeled efferent neurites. Subgroups of samples were also counterstained with either the panneuronal chromogen cuprolinic blue or with nNOS antibodies and steel gray chromogen to label nitrergic cells. | Purdue University, Purdue University, Purdue University, Purdue University | 1 | 2019 | Deborah Jaffey, Terry Powley, Jennifer Mcadams, Robert Phillips 2019.

Human Pancreas PACT Optical Clearing and High Resolution 3D Microscopy Resource Report Resource Website |
Elizabeth Butterworth, Wesley Dickerson, Vindhya Vijay, Kristina Weitzel, Julia Cooper, Eric W. Atkinson, Jason E. Coleman, Kevin Otto, Martha Campbell Thompson | 10.17504/protocols.io.9gbh3sn | Human Cell Atlas Method Development Community, Optical Clearing of Tissue, SPARC | Using traditional histological methods, researchers are hampered in their ability to image whole tissues or organs in large-scale 3D. Histological sections are generally limited to 500 μm using traditional methods. In addition, light scatters from macromolecules within tissues, particularly lipids, prevents imaging to a depth >150 μm with most confocal microscopes. To reduce light scatter and to allow for deep tissue imaging using simple confocal microscopy, various optical clearing methods have been developed that are relevant for rodent and human tissue samples fixed by immersion. Several methods are related and use protein crosslinking with acrylamide and tissue clearing with sodium dodecyl sulfate (SDS). Other optical clearing techniques used various solvents though each modification had various advantages and disadvantages. Here, an optimized passive optical clearing method is described for studies of the human pancreas innervation and specifically for interrogation of the innervation of human islets. | University of Florida, University of Florida, University of Florida, University of Florida, University of Florida, University of Florida, University of Florida, University of Florida, University of Florida | http://doi:10.3791/56859 | 1 | 2020 | Elizabeth Butterworth, Wesley Dickerson, Vindhya Vijay, Kristina Weitzel, Julia Cooper, Eric W.
