Effects of Selenium-mediated RUNX2 Overexpression and its Transcriptome Alterations on Chondrocyte Injury in Kashin Beck disease

ABSTRACT: Runt-related transcription factor 2 (RUNX2) is a key regulator of chondrocyte differentiation and apoptosis. To investigate the downstream molecular mechanisms of RUNX2 in chondrocyte injury, we established a RUNX2 overexpression model using lentiviral transfection in human chondrocytes. Total RNA was extracted from RUNX2-overexpressing and control chondrocytes and subjected to RNA sequencing. Differential expression analysis identified 263 upregulated and 216 downregulated genes in RUNX2-overexpressing cells compared with controls. Functional enrichment analysis revealed that these genes were predominantly involved in TNF and MAPK signaling pathways, suggesting that RUNX2 activation promotes inflammatory and apoptotic processes in chondrocytes. These results provide a comprehensive transcriptomic resource for understanding RUNX2-mediated signaling in cartilage degeneration and may contribute to elucidating the molecular pathogenesis of osteoarthropathy such as Kashin-Beck disease.

Integration of miRNA in exosomes and single-cell RNA-seq profiles in endemic osteoarthritis, Kashin-Beck disease

Project description:Kashin-Beck disease (KBD) is an endemic, chronic degenerative joint disease in China. Exosomes miRNAs, as signaling molecules in intercellular communication, can transfer specific biological martials into target cell to regulate the their function and might participate in the pathogenesis of KBD. We isolated serum and chondrocytes-derived exosomes, miRNA sequencing revealed exosomes miRNA profiles and differentially expressed miRNAs (DE-miRNAs) were identified. The target genes were predicted of known and novel DE-miRNAs with TargetScan 5.0 and miRanda 3.3a database. Single-cell RNA sequencing (scRNA-seq) was performed to identify chondrocyte clusters and their gene signatures in KBD. And we performed comparative analysis between the serum and chondrocytes-derived exosomes DE-miRNA target genes and differentially expressed genes of each cell clusters.A total of 20 DE-miRNAs were identified in serum-derived exosomes. In the miRNA expression of chondrocytes-derived exosomes, 53 DE-miRNAs were identified. 16063 predicted targets were identified as the target genes in the serum-derived exosomes, 57316 predicted targets were identified as the target genes in the chondrocytes-derived exosomes. Seven clusters were labelled by cell type according to the expression of previously described markers. 315 common genes were found among serum/chondrocytes-derived exosomes DE-miRNA target genes and DEGs identified by scRNA-seq analysis. We firstly integratly analyzed the serum and chondrocytes exosomes miRNA with single-cell RNA sequencing (scRNA-seq) data of KBD chondrocyte, the results showed that DE-miRNAs in exosomes might play a potential role in regulating genes expression in different KBD chondrocytes clusters by exosomes mediating cell-cell communications functions, which could improve the new diagnosis and treatment methods for KBD.

Peripheral blood mononuclear cells, control vs. Kashin-Beck Disease

Project description:Objective: To investigate the differences between the gene expression profiles in peripheral blood mononuclear cells (PBMC) from normal controls and patients with Kashin-Beck disease (KBD). Methods: Twenty KBD patients and 12 normal subjects were selected from a KBD-endemic area and divided into four pairs of KBD vs. control (KBD, n=5 per pair; control, n=3 per pair). RNAs were respectively isolated from KBD PBMCs and normal PBMCs. Gene expression profiles were analyzed by oligonucleotide microarray.

Genome-Wide Differentially Methylated Region Analysis to Reveal Epigenetic Differences of Articular Cartilage in Kashin-Beck Disease and Osteoarthritis

Project description:Kashin-Beck disease (KBD) is a degenerative osteoarticular disorder, and displays the significant differences with osteoarthritis (OA) regarding the etiology and molecular changes in articular cartilage. However, the underlying dysfunctions of molecular mechanisms in KBD and OA remain unclear. Here, we performed the various genome-wide differentially methylated region analyses to reveal the distinct differentially methylated regions (DMRs) and corresponding differentially methylated genes (DMGs), and enriched functional pathways/GO terms for KBD and OA.
