Proteomic profile of human Schwann cells

ABSTRACT: Schwann cells (SC) are essential to the growth, maintenance and regeneration of peripheral nerves, but the proteome of normal human SC is poorly defined. Here, we performed a proteomic analysis by liquid chromatography tandem mass spectrometry (LC-MS/MS) to identify the protein expression profile of primary human SC. A total of 19,557 peptides corresponding to 1,553 proteins were identified, with 1% false discovery rate (FDR). Ingenuity Pathway Analysis (IPA), Gene Ontology (GO) and Database for Annotation, Visualization and Integrated Discovery (DAVID) were used to assign protein localization and function, and to define enriched pathways. EIF2, mTOR and integrin signalling were among the most enriched pathways and the most enriched biological function was cell-cell adhesion, which is in agreement with the supportive role of SC in peripheral nerves. This proteome analysis of normal human SC may help in the molecular exploration of neurological and malignant diseases where SC are involved.

Comprehensive analysis of hypoxia-dependent expression of myelin-related genes in Schwann cells

Project description:Schwann cells (SC) generate myelin sheath in the peripheral nervous system. Several specific genes have been identified in SC during development of peripheral nerves. Expression of these genes has been also found in SC of peripheral nerves after injury or in demyelinating disorders. However, it remains unclear how these genes regulate SC differentiation and peripheral myelination. Here, we show the hypoxia induced factor-1α (HIF-1α) involvement in the regulation of SC differentiation and myelination. We used ChIL-seq technology to understand the comprehensive HIF-dependent gene expression in SC during myelination.

SKP-SC-EVs-derived miRNA-30a-5p promote angiogenesis in peripheral nerve regeneration by targeting Lif and ANGPT2

Project description:Ischemia and hypoxia caused by vascular injury aggravate nerve injury. The extracellular vesicles from skin precursor-derived Schwann cells (SKP-SC-EVs) have proven to be beneficial to the regeneration of peripheral nerve injury, but whether SKP-SC-EVs can repair injured peripheral nerves by promoting angiogenesis remains unclear. Here, we found that SKP-SC-EVs enhanced the angiogenesis, which were verified by the transparency of tissue engineered nerve graft (TENG) and ultrasonic blood flow imaging. In vitro we verified that SKP-SC-EVs promote the proliferation, migration and tube formation of human umbilical vein endothelial cells (HUVECs), which were traditionally used for the evaluating angiogenesis capacity. Furthermore, the expression pattern of microRNA (miRNA) in SKP-SC-EVs was profiled and functional experiments were screened. Notably, miR-30a-5p was selected because of the remarkably pro-angiogenic ability in vivo and in vitro, which was similar to the effects of SKP-SC-EVs. Luciferase reporter assay and functional experiments revealed miR-30a-5p contained in SKP-SC-EVs promoted angiogenesis by targeting ANGPT2 and LIF in the insufficient of VEGFa. Taken together, miR-30a-5p enriched in SKP-SC-EVs may be a key regulator of angiogenesis for the cell-free treatment for peripheral nerve injury.

Proteomics and transcriptomics of peripheral nerve tissue and cells unravel new aspects of the human Schwann cell repair phenotype

Project description:The remarkable feature of Schwann cells (SCs) to transform into a repair phenotype turned the spotlight on this powerful cell type. SCs provide the regenerative environment for axonal re-growth after peripheral nerve injury (PNI) and play a vital role in differentiation of neuroblastic tumors into a benign subtype of neuroblastoma, a tumor originating from neural crest-derived neuroblasts. Hence, understanding their mode-of-action is of utmost interest for new approaches in regenerative medicine, but also for neuroblastoma therapy. However, literature on human SCs is scarce and it is unknown to which extent human SC cultures reflect the SC repair phenotype developing after PNI in patients. We performed high-resolution proteome profiling and RNA-sequencing on highly enriched human SC and fibroblast cultures, control and ex vivo degenerated nerve explants to identify novel molecules and functional processes active in repair SCs. In fact, we found cultured SCs and degenerated nerves to share a similar repair SC-associated expression signature, including the upregulation of JUN, as well as two prominent functions, i.e., myelin debris clearance and antigen presentation via MHCII. In addition to myelin degradation, cultured SCs were capable of actively taking up cell-extrinsic components in functional phagocytosis and co-cultivation assays. Moreover, in cultured SCs and degenerated nerve tissue MHCII was upregulated at the cellular level along with high expression of chemoattractants and co-inhibitory rather than -stimulatory molecules. These results demonstrate human SC cultures to execute an inherent program of nerve repair and support two novel repair SC functions, debris clearance via phagocytosis-related mechanisms and type II immune-regulation.

Expression data for 2-month-old wild type and Tfam-SCKO (MPZ-Tfam KO) sciatic nerves

Project description:Gene expression analysis of 2-month-old Ctrl and Tfam-SCKO mice. At this age mitochondrial function is disrupted in the Schwann cells of Tfam-SCKO mice ,but their nerves display only very limited pathology. Mitochondrial dysfunction is a common cause of peripheral neuropathy. Much effort has been devoted to examining the role played by neuronal/axonal mitochondria, but how mitochondrial deficits in peripheral nerve glia (Schwann cells, SCs) contribute to peripheral nerve diseases remains unclear. Here, we investigate a mouse model of peripheral neuropathy secondary to SC mitochondrial dysfunction (Tfam-SCKOs). We show that disruption of SC mitochondria activates a maladaptive integrated stress response through actions of heme-regulated inhibitor kinase (HRI), and causes a shift in lipid metabolism away from fatty acid synthesis toward oxidation. These alterations in SC lipid metabolism result in depletion of important myelin lipid components as well as in accumulation of acylcarnitines, an intermediate of fatty acid b-oxidation. Importantly, we show that acylcarnitines are released from SCs and induce axonal degeneration. A maladaptive integrated stress response as well as altered SC lipid metabolism are thus underlying pathological mechanisms in mitochondria-related peripheral neuropathies. Total RNA samples were prepared by isolating and pooling RNA from three different 2-month-old MPZ-Tfam KO and Ctrl mice. 2 replicates per genotype were used in this experiment and they were prepared entirely independently.

Disentangling glial diversity in peripheral nerves at single-nuclei resolution [single-cell and single-nuclei RNA-seq]

Project description:The peripheral nerve contains diverse cell types that support its proper function and maintenance. We analyzed multiple peripheral nerves using single-nuclei RNA-sequencing (snRNA-seq), which allowed us to circumvent difficulties encountered in analyzing cells with complex morphologies via conventional single cell methods. The resultant mouse peripheral nerve cell atlas highlights a diversity of cell types, including multiple subtypes of SCs, immune cells, and stromal cells. We identified a distinct myelinating-SC subtype that expresses Cldn14, Adamtsl1, and Pmp2 and preferentially ensheathes motor axons. The number of these motor-associated, Pmp2+ SCs is reduced in both ALS SOD1G93A mouse model and human ALS nerve samples. Our findings reveal the diversity of SCs and other cell types in peripheral nerve and serve as a reference for future studies of nerve biology and disease.

The biological and molecular heterogeneity of breast cancers correlate with their cancer stem cell content

Project description:Pathways that govern normal stem cell (SC) function are often subverted in cancer. Here, we report the isolation to near purity of human normal mammary SC (hNMSCs), from cultured mammospheres, based on their ability to retain the lipophilic dye PKH26 as a consequence of their quiescent nature. We demonstrated that PKH26-positive cells possess all the characteristics of hNMSCs. The transcriptional profile of PKH26-positive cells (hNMSC signature) was able to predict biological and molecular features of breast cancers. By using markers of the hNMSC signature, we could prospectively isolate SCs from the normal gland and from breast tumors. Poorly-differentiated aggressive (G3) cancers displayed higher content of prospectively isolated cancer SCs, than well-differentiated less aggressive (G1) cancers. By comparing G3 and G1 tumors in xenotransplantation experiments, we directly demonstrated that G3s are enriched in cancer SCs. Our data support the notion that the heterogeneous phenotypical and molecular traits of human breast cancers are a function of their SC content.

Genome-wide location analysis of WNT (Tcf7l2) and BMP (SMAD1) in human hematopoeitic progenitors co-occupied with lineage specific regulators (GATA1, GATA2)

Project description:Lineage regulators direct BMP and Wnt pathways to cell-specific programs during differentiation and regeneration. This represents the human CD34 ChIP-seq portion of this dataset. Human hematopoietic cells were cross-linked with formaldehyde for 20 min. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. A sample of whole cell extract (WCE) was sequenced and used as the background to determine enrichment. ChIP was performed using an antibody against total Smad1 (Santa Cruz SC-7965), Tcf7l2 (Santa Cruz SC-8631),Gata1 (Santa Cruz SC-265), Gata2 (Santa Cruz SC-9008) or CEBPA (SC-9314).

Barley guard cell and subsidiary cell specific transcripts

Project description:We prepared RNA from total leaves and epidermal peels, containing living guard cells (GC) and subsidiary cells (SC) only. In the third sample we blended epidermal peels to mechanically destroy the SC, leading to a pure guard cells fraction. By RNAseq and substraction of GC from SC transcripts, we were able to reliably assign transcripts to the barley SCs and GCs.
