Expression data from bovine nucleus pulposus interverteral disc cells

ABSTRACT: Assessment of the putative differential gene expression profiles in high osmolality-treated bovine nucleus pulposus intervertebral disc cells for a short (5 h) and a long (24 h) time period. Identification of novel genes up- or down-regulated as an early or a late response to hyperosmotic stress. A 5 and 24 h-hyperosmotic treatment of nucleus pulposus cells led to transcriptional changes in >100 and 200 genes, respectively.

Expression data from bovine nucleus pulposus interverteral disc cells

Project description:Assessment of the putative differential gene expression profiles in high osmolality-treated bovine nucleus pulposus intervertebral disc cells for a short (5 h) and a long (24 h) time period. Identification of novel genes up- or down-regulated as an early or a late response to hyperosmotic stress. A 5 and 24 h-hyperosmotic treatment of nucleus pulposus cells led to transcriptional changes in >100 and 200 genes, respectively. Nucleus pulposus intervertebral disc cells were exposed to hyperosmotic stress for 5 and 24 h before RNA extraction and transcriptomics analysis. Three biological replicates were tested for each condition. Selected genes found to be differentially expressed were validated by RT-qPCR. Functional experiments were performed in order to assess the role of specific proteins encoded by genes found to be up-regulated in the osmo-reguatory response of intervertebral disc cells.

Single cell sequencing of human nucleus pulposus

Project description:In order to discover the cell type in nucleus pulposus and find the cell type specific genetic change during intervertebral disc degeneration, we applied single cell RNA sequencing of nucleus pulposus tissue from degenerated and non-degenerated disc.

RNA sequencing reveals RNA binding protein HuR/ELAVL1 regulates extracellular matrix gene expression in nucleus pulposus cells of the intervertebral disc

Project description:We used RNA sequencing to identify transcripts that were controlled by the RNA binding factor HuR/ELAVL1 in nucleus pulposus cells of the intervertebral disc.

Increased HIF-2α Activity in the Nucleus Pulposus Causes Mild Degenerative Changes in the Intervertebral Disc in the Aging Mouse Spine

Project description:Transcriptomic analysis of nucleus pulposus (NP) tissues from intervertebral discs of 14- and 24-month-old mice with the conditional postnatal overexpression of HIF-2α. Hypoxia-inducible factors (HIFs) are essential for the homeostasis of the hypoxic tissues, and therefore, increased activity of the transcription factor HIF-2α is shown to contribute to the pathogenesis of mild disc degeneration in the spine. We examined the transcriptomic profiles of nucleus pulposus cells in control and K19-HIF-2α-dPA overexpression mice using microarrays.

N6-methyladenosine circRNA Epitranscriptomic Microarray of human nucleus pulposus in intervertebral disc degeneration

Project description:It is well documented that low back pain is a common condition and the leading cause of disability globally. A widely recognised contributor to low back pain is intervertebral disc degeneration (IVDD), which is the major cause of a series of degenerative disc diseases. Recently, it has been reported that circRNAs are involved in the development of IVDD. However, the mechanisms by which m6A modifies circRNA in nucleus pulposus cells remain poorly understood. Here, we aim to identify differentially expressed m6A circRNAs in degenerative nucleus pulposus cells and figure out how the circRNAs regulate IVDD progression and the m6A methylation functions.

Transcription profiling of bovine nucleus pulposus, carticular cartilage and annulus fibrosus cells to further determine expression in normal and degenerate human intervertebral disc

Project description:The aim of this transcription profiling study was to identify novel genes that could be used to distinguish bovine Nucleus pulposus (NP) cells from articular cartilage (AC) and annulus fibrosus (AF) cells and to further determine their expression in normal and degenerate human intervertebral disc (IVD). This study has identified a number of novel genes that characterise the bovine and human NP and IVD cell phenotypes and allows for discrimination between AC, AF and NP cells.<br><br>

Lactate Efflux From Intervertebral Disc Cells Is Required for Maintenance of Spine Health

Project description:Monocarboxylate Transporter 4 (MCT4) is important for H+/lactate efflux from nucleus pulposus cells in the intervertebral disc of mice. We examined the transcriptomic profile of nucleus pulposus cells in wild-type and MCT4 global knock-out mice using microarrays.

Sox9 Deletion Causes Severe Intervertebral Disc Degeneration Characterized by Apoptosis, Matrix Remodeling, and Compartment-Specific Transcriptomic Changes

Project description:Transcriptomic analysis of nucleus pulposus (NP) and annulus fibrosus (AF) tissues from intervertebral discs of 3-month-old mice with the conditional postnatal deletion of Sox9. The transcription factor Sox9 is essential for the maintenance and health of the intervertebral disc of mice. We examined the transcriptomic profiles of nucleus pulposus and annulus fibrosus cells in control and Sox9 conditional knock-out mice using microarrays.

Expression data from young and old nucleus pulposus stem cells

Project description:Nucleus pulposus stem cells is the endogenous stem cell in nucleus pulposus tissues(NPMSCs). The senescene of NPMSCs will cause its malfunction and further induce intervertebral disc degeneration.The expression of specific sets of genes will altered during aging. Thus, identify these key regulater genes is important. We used microarrays to detail the global programme of gene expression underlying NPMSCs aging and identified distinct classes of up and down-regulated genes during this process

RNAseq analyses of nucleus pulposus cells treated with control siRNA and LINC02569 siRNA

Project description:Nucleus pulposus cells (NPCs) were used to examine the effect of LINC02569, a novel lncRNA. In particular, its effect in intervertebral disc degeneration was determined. Treatment of LINC02569 siRNA (si-02569) was to be compared with negative control siRNA (si-NC).
