Moreover, SIRT3 was downregulated in OC tissues, which was negatively correlated to PKMYT1. Silencing of SIRT3 could abolish the regulatory effect of PKMYT1 on proliferative and metastatic abilities in OC. Conclusions Upregulated PKMYT1 in OC is closely linked to distant metastasis and poor prognosis. PKMYT1 accelerates the malignant progression of OC via negatively regulating SIRT3.Objective Osteoarthritis (OA) is a common disease in the elderly and seriously affects the quality of life of patients. The purpose of this study was to explore the protective effect of Fibulin-5 on articular chondrocytes and its mechanism of action. Patients and methods Articular cartilage tissues from patients with OA and normal people were selected and tested for differences in Fibulin-5 expression. In addition, human chondrocytes were cultured, and the effects of Fibulin-5 on the extracellular matrix (ECM) of chondrocytes and the level of inflammation were examined by means of cell transfection and cytokine intervention. SKL2001, an agonist of the Wnt/β-catenin signaling pathway, was used to validate the mechanism of action of Fibulin-5 to protect chondrocytes. Results Fibulin-5 was lowly expressed in the cartilage tissue of patients with OA. Overexpression of Fibulin-5 significantly increased the expressions of ECM collagen II and aggrecan in chondrocytes, while decreasing the expressions of MMP-3 and MMP-13. In addition, Fibulin-5 reduced IL-1β-induced inflammation of chondrocytes, as well as expressions of IL-6, IL-8, and TNF-α. Overexpression of Fibulin-5 also reduced the activity of Wnt/β-catenin signaling pathway, and activation of Wnt/β-catenin signaling pathway attenuated the protective effects of Fibulin-5 on the ECM of chondrocytes. Conclusions Fibulin-5 can protect the ECM of chondrocytes and reduce the inflammatory response of chondrocytes by inhibiting the Wnt/β-catenin signaling pathway.Objective To study the influences of long non-coding ribonucleic acid (lncRNA) maternally expressed gene 3 (MEG3) on the proliferation and apoptosis of synovial cells in rats with knee osteoarthritis by regulating phosphate and tension homology deleted on chromosome ten (PTEN). Materials and methods In this experiment, rat synovial cell (RSC)-364 cells were cultured in vitro. Then, they were treated with PBS or lncRNA MEG3 overexpression lentiviruses and divided into normal control (NC) group and lncRNA MGE3 overexpression group (LncRNA MEG3 group). The messenger RNA (mRNA) expression levels of lncRNA MEG3 and PTEN in rat synovial cells were measured via qRT-PCR in each group, and Western blotting (WB) was performed to determine the protein levels of PTEN, cyclin D1, P21, B-cell lymphoma 2 (Bcl-2) and tubulin in rat synovial cells in both groups. The proliferation of rat synovial cells was detected via MTT assay, and the apoptosis was evaluated using FITC/PI double staining and flow cytometer. Results Compared with NC group, LncRNA MEG3 group had notably overexpressed lncRNA MEG3 in RSC-364 cells (p less then 0.01), and an extremely substantially elevated mRNA level of PTEN (p less then 0.05). Besides, it was found through WB that the protein expression level of PTEN had a consistent trend with that of the mRNA level. The proliferation ability of cells was weakened (p less then 0.05), and the number of apoptotic cells was increased (p less then 0.05) in LncRNA MEG3 group compared with those in NC group. Finally, LncRNA MEG3 group had remarkably lower protein levels of cyclin D1 and Bcl-2, but a markedly higher protein level of P21 than NC group (p less then 0.05). Conclusions LncRNA MEG3 can raise the level of PTEN to weaken the proliferation ability but elevate the apoptosis level of RSC-364 cells.Objective The intervertebral disc contains abundant extracellular matrix (ECM) imbued with proteoglycans, collagens, and water. With the development of intervertebral disc degeneration (IVDD), the ECM undergoes changes characterized by loss of water content, proteoglycans, and collagen content. The purpose of this study was to explore the vital role of Matrilin-3, an ECM protein involved in the progress of IVDD. Materials and methods NP cells were isolated from the patients' disc samples and exposed to recombinant human (rh)-Matrilin-3 protein (MATN3), and IL-1β is used as a reducer of nucleus pulposus (NP) cells degeneration. Matrilin-3 and IL-1 receptor antagonist (IL-1Ra) were knocked down by siRNA transfection. Messenger RNA expressions of IL-1Ra, Collagen II, aggrecan, MMP-13, and ADAMTS-5 were determined using Real-Time quantitative Polymerase Chain Reaction (RT-qPCR). Later, the protein levels of IL-Ra, Collagen II, and aggrecan were also detected by Western blot. The IL-1Ra, MMP-13, and ADAMTS-5 dose MATN3 efficiently protects ECM degeneration of human NP cells related to maintain the content of Collagen II and aggrecan, as well as inflammatory inhibition.Objective This study aims to investigate the protective role of miRNA-203a-3p in preeclampsia (PE) patients via inhibiting the inflammatory key protein IL24. Patients and methods Serum samples of 36 PE pregnant women and 30 normal pregnant volunteers hospitalized between 2015 and 2019 were collected to extract placental mononuclear cells and exosomes. Relative levels of microRNA-203a-3p and IL24 were examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). In addition, the interaction between microRNA-203a-3p and IL24 was analyzed through bioinformatics analysis and Luciferase reporting assay. Etomoxir research buy Finally, the underlying molecular mechanisms were further explored via immunofluorescence and Western blotting. Results Compared with normal pregnant volunteers, microRNA-203a-3p expression in serum exosomes and placental mononuclear cells of PE patients were dramatically reduced, while IL24 was conversely up-regulated, indicating a negative correlation between microRNA-203a-3p and IL24 levels. In addition, IL24, which was down-regulated in mononuclear macrophages overexpressing microRNA-203a-3p, was indicated as a target of microRNA-203a-3p. At the same time, microRNA-203a-3p was able to suppress the proliferation capacity of LPS-stimulated mononuclear macrophages, and it exerted anti-inflammatory effects via down-regulating IL24 in THP-1 cells. Conclusions MicroRNA-203a-3p plays an anti-inflammatory role in PE pregnant women by down-regulating IL24 level.Etomoxir research buy
