Bulk RNA-sequencing of spinocerebellar tract neuron populations in cervical and thoracic sections of mouse spinal cord

ABSTRACT: We profiled populations of mouse spinocerebellar tract neurons (SCTNs) in cervical and thoracic sections of mouse spinal cord, as defined by retrograde projection labeling. For each sample, SCTNs were labeled by injecting CTB (Alexa555 conjugated form, 1µg/µl in PBS) into the cerebellum using NanojetII at P4 and examined at P6-P7. Labeled SCTNs were collected manually from 150-300µm transverse spinal cords slices were generated using a razor blade. Cells were collected from each injection experiment and then profiled using standard Illumina bulk RNA-seq protocols

Expression data from Aspergillus niger comparing aerial structures with vegetative mycelium

Project description:A. niger undergoes dramatic changes during asexual development. We tried to identify the differences in RNA expression levels that are important for this development. We used micro-arrays to determine which genes were up- or down-regulated in the aerial structures, the part of the colony that is formed during asexual development. A. niger was grown as a sandwiched culture (Wösten et al., 1991,Journal of General Microbiology 137: 2017–2023) in a 0.25 mm layer of 0.6 % agarose between two porous polycarbonate membranes (diameter 76 mm, pore size 0.1 µm; Profiltra; www.profiltra.nl). After six days of growth, the top membrane of the sandwich was replaced by a membrane with pores of 10 µm (Profiltra), allowing formation of aerial hyphae and conidiophores for 24 h. Vegetative mycelium and aerial structures of 7-day-old maltose-grown cultures of A. niger were harvested from 3 and 5 sandwiched colonies, respectively. The aerial structures were scraped from the top membrane of the sandwiched culture with a razor blade. From other colonies, vegetative mycelium was harvested by flipping over the top membrane and scraping it off with a razor blade.

Gene expression profiling of LMC and MMC motor neurons in SMA mice

Project description:Spinal muscular atrophy (SMA) is a neurodegenerative disease which exhibits selective motor neuron death caused by a ubiquitous deficiency of the survival motor neuron (SMN) protein. It remains unclear how the ubiquitous reduction of SMN lead to death in selective motor neuron pools. Medial motor neuron columns (MMC) are vulnerable, whereas lateral motor columns (LMC) are resistant to motor neuron death in SMA. Here we performed microarray and pathway analysis comparing cholera toxin subunit B (CTb) labeled vulnerable MMC and resistant LMC of pre-symptomatic SMA with corresponding motor neuron columns of control mice to identify pathways involved in selective motor neuron death in SMA. WT is FVB. SMN is Delta7 (SMNΔ7;SMN2;Smn-) on a FVB background.

Identification of genes expressed during ROL barrier formation in rice root

Project description:Potential components of the barrier to radial oxygen loss (ROL) are suberin and/or lignin, which accumulate at the cell wall in the cells of peripheral cell layers of the root. Chemical composition of the apoplastic barrier in rice roots was characterized and it was suggested that ROL can be restricted by the formation of a suberized exodermis and/or lignified sclerenchyma in the outer part of the root. To characterize reorganization of primary carbon metabolism in rice roots during the ROL barrier formation, we obtained the profiles of polar metabolites and the profiles of fatty acids of different zones of rice roots from plants growing in stagnant (anaerobic) and in well aerated medium. Biochemical data are combined with the results of microarray analysis. Nine days after germination, the seedlings were transferred to well aerated nutrient solution or stagnant deoxygenated nutrient solution. Stagnant solution contained 0.1% (w/v) dissolved agar and was deoxygenated (dissolved oxygen, <0.5 mg lM-bM-^@M-^S1) prior to use by flushing with N2 gas. After 14 d (23 d old), adventitious roots, 100-150 mm long, were harvested from rice plants grown either in aerated or stagnant conditions and RNA was extracted from 10 mm segments from the regions 0-10 mm, 10-20 mm and 20-30 mm from the root apex have been cut with sterile razor blade and collected and processed separately. Total RNAs were labeled with a Quick Amp Labeling Kit (Agilent Technologies) according to the manufacturerM-bM-^@M-^Ys instructions. Aliquots of Cy5-labeled and Cy3-labeled cRNA (825 ng each) were used for hybridization in a rice 44K oligo-DNA microarray.

RNA-seq of an adult Porites rus colony derived from Indonesia

Project description:An adult P. rus colony was imported from Indonesia following the CITES protocols (Permit number 14846/IV/SATS-LN/2007) and kept in the Animal Facilities of the Justus Liebig University, Giessen. The colony was maintained in a circulating artificial seawater system at approximately 26 °C with 20-40 µmol photons m-2s-1 (T5 light) of photosynthetically active radiation on a 10:14 h light-dark cycle. A fragment of approx. 9 cm2 was separated from the colony and used as a source of tissue for hologenomic DNA/RNA isolation. Tissue was removed by scraping the fragment´s surface with a sterilized razor blade.

BMP4-directed trophoblast differentiation of human embryonic stem cells is mediated through a ΔNp63+ cytotrophoblast stem cell state

Project description:We show that FCM-BMP4-treated hESC differentiate into bona fide CTB by direct comparison to primary human placental tissues and isolated CTB through gene expresson profiling. We have compared gene expression profiling of FCM-BMP4-treated hESC to a panel of fetal tissues and first trimester tissues. Moreover, we have analysed the expression profiles of cells after shRNA knock-down of p63 compared to Scramble upon BMP4 treatment. Difference in expression between CTB trimester 1 / trimester 3 and PSC were compared the difference between FCM-BMP4-treated hESC and PSC at each time point collected.

Transcription profiling time series analyzing the molecular events in rat spinal cord sections following mechanical injury

Project description:Summary: Spinal cord injury (SCI) is a damage to the spinal cord induced by trauma or disease resulting in a loss of mobility or feeling. SCI is characterized by a primary mechanical injury followed by a secondary injury in which several molecular events are altered in the spinal cord often resulting in loss of neuronal function. Hypothesis: Spinal cord injury (SCI) induces a cascade of molecular events including the activation of genes associated with transcription factors, inflammation, oxidative stress, ionic imbalance, apoptosis and neuroregeneration which suggests the existance of endogenous reparative attempts. However, not all mechanisms following SCI are well known. Specific Aim: The goal of this project is to analyze the molecular events following spinal cord injury 1 cm above, below, and at the site of injury (T9), aiming at finding potential new targets to improve recovery and therapy.

RNAseq of human Multiple Sclerosis cortex with hnRNP A1 dysfunction

Project description:We sought to identify alterations in RNA expression and splicing in human grey matter from the brains of people with Multiple Sclerosis (MS) where we observe mislocalization of the RNA binding protein hnRNP A1. Thus, RNA was extracted from fresh-frozen post-mortem brain samples of three people with MS and compared to RNA extracted from fresh-frozen post-mortem brain samples of three healthy controls by RNAseq. Regions of interest in human grey matter were defined by immunostaining for hnRNP A1 to confirm grey matter regions with hnRNP A1 mislocalization in MS tissue, and grey matter regions with normal hnRNP A1 localization in control tissue, and the same region from an adjacent tissue section was dissected with a razor blade and used for RNA extraction and sequencing.

Microarray analysis of normal and abnormal chick myocardial development

Project description:The goal of this study was to determine developmental differences in gene expression between left and right ventricle, and to assess the differential effect of altered hemodynamic loading on left and right ventricle. Chick ventricles from different developmental stages were isolated for assessment of normal developmental profiles. Conotruncal banding or partial ligation of the left atrial appendage was performed in ovo at embryonic day 4 and ventricles were isolated at embryonic day 5 (banding) or 8 (ligation) for assessment of altered loading effects. Normal heart and ventricle tissues were collected from chicks at embryonic day 4, 5, 6, 8, or 10 (Hamurger-Hamilton stages 29, 34, and 36). Conotruncal banding (CTB) or left atrial ligation (LCL) was performed for experimental groups in ovo at embryonic day 4 and tissues isolated at embryonic day 5 (CTB) or day 8 (LAL). For each sample type, tissues were carefully dissected, collected and stored in RNAlater, and then pooled for RNA isolation. Each sample contained 6 to 12 separate biological specimens. A single pooled RNA sample was generated for each normal and experimental condition. Following preparation of labeled samples for hybridization, samples were split and hybridized in duplicate to separate microarrays (i.e., technical replicates).
