[PMID: 36610331 DOI: 10.1016/j.intimp.2022.109643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 12/22/2022] [Accepted: 12/23/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Osteoarthritis (OA) is a serious degenerative disease of articular cartilage, which has a great impact on the quality of life of patients. Circular RNA (circRNA) plays an important role in OA progression. Our study aims to explore the role and mechanism of circ_0003800 in OA. METHODS Circ_0003800, microRNA-197-3p (miR-197-3p) and SRY-box transcription factor 5 (SOX5) contents were measured by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. Cell Counting Kit-8 (CCK8), 5-ethynyl-2'-deoxyuridine (EdU), flow cytometry, western blot and enzyme-linked immunosorbent assay (ELISA) were deployed to evaluate cell proliferation, apoptosis, extracellular matrix (ECM) degradation, inflammatory response and oxidative stress. Interaction of miR-197-3p and circ_0003800 or SOX5 was evidenced by dual-luciferase reporter system, RNA immunoprecipitation (RIP) and RNA pull down assays. RESULTS OA tissues and model cells had higher abundance of circ_0003800 and SOX5, while miR-197-3p content was lower. Functionally, circ_0003800 knockdown alleviated IL-1β-mediated injury in C28/I2 cells. Mechanistically, circ_0003800 could sponge miR-197-3p, and miR-197-3p could target SOX5. Besides, in-miR-197-3p reversed the suppressive effect of circ_0003800 downregulation on IL-1β-induced C28/I2 cell injury, and SOX5 overexpression could also diminish the inhibitory effect of miR-197-3p on IL-1β-induced C28/I2 cell injury. CONCLUSION Circ_0003800 exacerbates IL-1β-induced chondrocyte injury via miR-197-3p/SOX5 axis.

[PMID: 33751650 DOI: 10.1002/bab.2145] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Accepted: 02/22/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Osteoarthritis (OA) is a common joint disease. Currently, many studies have revealed that circular RNAs (circRNAs) are strongly related to the occurrence and development of diseases. Hence, we aimed to further elucidate the role and molecular mechanism of circRNA SEC24 homolog A, COPII coat complex component (circSEC24A) in OA. METHODS Chondrocytes were treated with interleukin-1β (IL-1β) to establish OA cell model in vitro. The expression levels of circSEC24A, microRNA-142-5p (miR-142-5p), and sex-determining region Y-box protein 5 (SOX5) were determined by quantitative real-time polymerase chain reaction. MTT and colony formation assays were used to determine cell proliferation. Cell apoptosis was detected by flow cytometry analysis. The protein levels of inflammatory factors and SOX5 were determined by western blot assay. The relationship between miR-142-5p and circSEC24A or SOX5 was confirmed using dual-luciferase reporter assay and RNA immunoprecipitation assay. RESULTS CircSEC24A and SOX5 expression were enhanced, while miR-142-5p level was reduced in OA cartilage tissues and chondrocytes. Overexpression of circSEC24A promoted IL-1β-induced injury through decreasing cell proliferation and increasing apoptosis and inflammation in chondrocytes. MiR-142-5p was a direct target of circSEC24A, and its upregulation ameliorated IL-1β-induced injury and abated the effect of oe-circSEC24A in IL-1β-induced chondrocytes. Additionally, SOX5 was a downstream target of miR-142-5p, and its overexpression had a similar role with oe-circSEC24A and reversed the impact of miR-142-5p in IL-1β-induced chondrocytes. CircSEC24A acted as a molecular sponge of miR-142-5p to regulate SOX5 expression in chondrocytes. CONCLUSION CircSEC24A aggravated IL-1β-induced injury via modulating miR-142-5p/SOX5 axis, providing possible targets for the clinical diagnosis and treatment of OA.

Abstract
Long non-coding RNAs (lncRNAs) were reported to be involved in the progression of osteoarthritis (OA). The aim of this work was to explore the functional role of lncRNA nuclear-enriched abundant transcript 1 (NEAT1) in OA. Reverse-transcription quantitative polymerase chain reaction (RT-qPCR) was employed to analyze the expression of microRNA (miR-193a)-3p, NEAT1, and sex-determining region Y-box protein 5 (SOX5), as well as the levels of pro-inflammatory cytokines interleukin-6 (IL-6), IL-1β, tumor necrosis factor-α (TNF-α), and IL-8 in OA cartilage tissue and chondrocytes. In addition, flow cytometry was used to measure the apoptosis of chondrocytes. The protein levels of extracellular matrix ACAN, collagen type II α1 chain (Col2a1), matrix metalloproteinase-3 (MMP-3), MMP-13, a disintegrin, and metalloproteinase with thrombospondin motifs (ADAMTS)-5 and SOX5 were determined using western blot analysis. Dual-luciferase reporter assay was performed to determine the target relationship among NEAT1, miR-193a-3p, and SOX5. We found that miR-193a-3p expression was downregulated, while NEAT1 and SOX5 were upregulated in OA cartilage tissue and chondrocytes. Both upregulation of miR-193a-3p and knockdown of NEAT1 suppressed inflammation, apoptosis, and reduced the protein levels of MMP-3, MMP-13, and ADAMTS-5, while elevating ACAN and Col2a1 expression in chondrocytes. NEAT1 targeted miR-193a-3p, and SOX5 was targeted by miR-193a-3p. Silencing of miR-193a-3p reversed the NEAT1 knockdown-mediated effect on the inflammation, apoptosis, and production of the extracellular matrix. The introduction of SOX5 abolished the impact of the upregulation of miR-193a-3p on inflammation, apoptosis, and production of extracellular matrix in chondrocytes. In conclusion, NEAT1/miR-193a-3p/SOX5 axis regulates cartilage matrix degradation in human OA.

Abstract
Periodontitis leads to destruction of periodontal ligament, cementum and alveolar bone. Regeneration of periodontal tissue is dependent on mesenchymal stem cells (MSC) present in the periodontal ligament, and transcription factors determine the direction of MSC differentiation. The present study was conducted to investigate the transcription factors that are crucial for maintaining the characteristics of the periodontal ligament. The mRNA levels of several transcription factors were measured in cultured human periodontal ligament (HPDL) cells, human gingival fibroblasts and osteoblast-like Saos2 cells. HPDL cells were transfected for 72 h with siTwist2, siKlf12, or siMix (siTwist2, siPax9, and siKlf12). The cells were then harvested and subjected to real-time PCR and Western blotting. siTwist2 suppressed the levels of Twist2, Sox2 and Col1a1 mRNAs, and increased those of Sox5 and aggrecan mRNAs. siKlf12 decreased the mRNA levels of Klf12, Runx3, Zfp521, and Stab2, and increased those of Sox2, Klf4, and the MSC markers CD90 and CD105. These results suggest that transfection with siMix and siTwist2 induced chondrogenesis, and that siKlf12 induced the differentiation of MSC in HPDL cells. Thus, inhibition of Twist2 or Klf12 induced the differentiation of chondrogenic or mesenchymal stem cells in this setting, suggesting that the characteristics of HPDL cells may be altered by inhibition of specific transcription factors.

Abstract
The transcription factor Runx3 is a known tumor suppressor gene, and its expression is frequently lost in melanoma. However, the potential contribution of the loss of Runx3 expression to melanoma development and progression remains unclear. In this in vitro study, we demonstrated that ectopic Runx3 re-expression in B16-F10 melanoma cells changed the cell shape from elongated and branched to spread and unbranched, which enhanced stress fiber formation, increased the number of mature and fibrillar focal adhesions, and up-regulated fibronectin expression. In association with the cell shape change, the Runx3 re-expression in B16-F10 melanoma cells inhibited cell migration. Moreover, the phenotype of the Runx3 induced cell shape change was partially resembled when the melanoma cells were cultured on a fibronectin-coated coverslip, suggesting that fibronectin may mediate the Runx3 induced cell shape change of the melanoma cells. Taken together, our findings suggest that Runx3 may regulate cell shape to inhibit melanoma cell migration partly through enhancing stress fiber formation and ECM protein production. Our present study provides further evidence for the idea that cell shape change is potentially correlated with melanoma development and progression.
