Gene expression in FIH-1 silenced human nucleus pulposus cells

ABSTRACT: To evaluate the effect of Hypoxia-inducible factor 1-alpha inhibitor (HIF-1) in nucleus pulposus (NP) cells, human NP cells were lentivirally transduced with either control or FIH-1 targeted shRNA. Gene expression changes between samples from control and FIH-1 silenced cells were evaluated using a microarray.

Gene expression in FIH-1 silenced human nucleus pulposus cells

Project description:To evaluate the effect of Hypoxia-inducible factor 1-alpha inhibitor (HIF-1) in nucleus pulposus (NP) cells, human NP cells were lentivirally transduced with either control or FIH-1 targeted shRNA. Gene expression changes between samples from control and FIH-1 silenced cells were evaluated using a microarray. Primary NP cells were isolated from human discs and grown in culture. Cells were transduced with either control or FIH-1 targeting shRNA constructs. Silencing of FIH-1 was confirmed for each set using qRT-PCR and Western blot. Total RNA from NP cells was used for RNA extraction and hybridization on the Affymetrix microarray. Control samples: C1, C2, and C3 and FIH-1-silenced samples: E1, E2, and E3.

Conditional deletion of HIF-2α in mouse nucleus pulposus reduces fibrosis and provides mild and transient protection from age-dependent structural changes in intervertebral disc

Project description:Hypoxia inducible factors (HIFs) are critical to the development and homeostasis of the intervertebral disc. While HIF-2α, one of the main HIF-α isoforms is expressed in nucleus pulposus (NP) cells, its functions remain unknown. We used microarrays to explore the transcriptomics of differentially expressed genes between control and HIF-2α cKO NP cells in 6M and 14M mice.

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.

GLUT1 is redundant in hypoxic and glycolytic nucleus pulposus cells of the intervertebral disc

Project description:Glucose is critical to the development, homeostasis, and survival of nucleus pulposus cells. GLUT1 is a major glucose transporter, a NP phenotypic cell marker, and highly expressed in nucleus pulposus (NP) cells, however its level of importance in NP cell development and homeostasis is unknown. We used microarrays to explore the transcriptomics of differentially expressed genes between wildtype and Glut1 cKO NP cells in 9-month-old mice.

Human iPS cell-derived cartilage spatially and functionally replaces nucleus pulposus

Project description:Single cell RNA sequencing (scRNA-seq) analysis identified notochordal nucleus pulposus (NP) cells and chondrocyte-like NP cells in NP. Cells in human induced pluripotent stem cell-derived cartilage (hiPS-Cart) corresponded to chondrocyte-like NP cells but not to notochordal NP cells. hiPS-Cart cells changed their profile after implantation into intervertebral disks of nude rats, differentiating into two lineages that are metabolically distinct from each other. However, post-implanted hiPS-Cart cells corresponded to chondrocyte-like NP cells only and did not develop into notochordal NP cells.

Single-cell sequencing reveals cellular heterogeneity of nucleus pulposus in intervertebral disc degeneration

Project description:Nucleus pulposus (NP) plays a vital role in intervertebral disc degeneration (IVDD). Previous studies have revealed cellular heterogeneity in the NP tissue during IVDD progression. Here, we used single cell RNA sequencing (scRNA-seq) to analyze the cellular and molecular alterations of diverse cell clusters during IVDD.

Expression data from synovium, bone marrow and nucleus pulposus

Project description:Synovial and bone marrow mesenchymal stem cells after intradiscally injection show regenerative effects of nucleus pulposus. Microarray analyses of rats were performed to investigate the closeness of the gene profiles between the nucleus pulposus cells and the synovial or bone marrow mesenchymal stem cells. To investigate interaction between synovial mesenchymal stem cells and nucleus pulposus cells, human synovial mesenchymal stem cells and rat nucleus pulposus cells were co-cultured, and species specific microarray were performed. Synovium of knee joints, bone marrow and nucleus pulposus were harvested from rat or human, and cells were isolated for RNA extraction and hybridization on Affymetrix microarrays. To compare the gene profiles each other, isolated cells were mono-cultured respectively, and human synovial mesenchymal stem cells and rat nucleus pulposus cells were co-cultured.

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>
