Mulberroside A alleviates osteoarthritis via restoring impaired autophagy and suppressing MAPK/NF-κB/PI3K-AKT-mTOR signaling pathways.

Osteoarthritis (OA) is a trauma-/age-related degenerative disease characterized by chronic inflammation as one of its pathogenic mechanisms. Mulberroside A (MA), a natural bioactive withanolide, demonstrates anti-inflammatory properties in various diseases; however, little is known about the effect of MA on OA. We aim to examine the role of MA on OA and to identify the potential mechanisms through which it protects articular cartilage.

Oroxin B alleviates osteoarthritis through anti-inflammation and inhibition of PI3K/AKT/mTOR signaling pathway and enhancement of autophagy.

Background: Osteoarthritis (OA) is a common aging-related degenerative joint disease with chronic inflammation as its possible pathogenesis. Oroxin B (OB), a flavonoid isolated from traditional Chinese herbal medicine, possesses anti-inflammation properties which may be involved in regulating the pathogenesis of OA, but its mechanism has not been elucidated. Our study was the first to explore the potential chondroprotective effect and elucidate the underlying mechanism of OB in OA.

Inhibition of GAB2 expression has a protective effect on osteoarthritis:An in vitro and in vivo study.

Osteoarthritis is a chronic age-related degenerative disease associated with varying degrees of pain and joint mobility disorders. Grb2-associated-Binding protein-2 (GAB2) is an intermediate molecule that plays a role downstream in a variety of signaling pathways, such as inflammatory signaling pathways. The role of GAB2 in the pathogenesis of OA has not been fully studied.

Endogenous conversion of n-6 to n-3 polyunsaturated fatty acids facilitates the repair of cardiotoxin-induced skeletal muscle injury in mice.

In this study, we investigated the beneficial effects of high endogenous levels of n-3 polyunsaturated fatty acids (PUFAs) on skeletal muscle repair and regeneration using a mouse cardiotoxin (CTX, 20 μM/200 μL) -induced gastrocnemius muscle injury model. Transgenic mice expressing the gene, encoding n-3 fatty acid desaturase, showed higher n-3 PUFA levels and lower n-6/n-3 PUFA ratios in gastrocnemius muscle tissues. Hematoxylin and eosin and Masson's trichrome staining of gastrocnemius sections revealed increased muscle fiber size and reduced fibrosis in mice on days 7 and 14 after CTX injections.

Comprehensive proteomic analysis of exosomes derived from human bone marrow, adipose tissue, and umbilical cord mesenchymal stem cells.

Background: Mesenchymal stem cell (MSC)-derived exosomes have shown comprehensive application prospects over the years. Despite performing similar functions, exosomes from different origins present heterogeneous characteristics and components; however, the relative study remains scarce. Lacking of a valuable reference, researchers select source cells for exosome studies mainly based on accessibility and personal preference.

Decreased RIPK1 expression in chondrocytes alleviates osteoarthritis via the TRIF/MyD88-RIPK1-TRAF2 negative feedback loop.

Osteoarthritis (OA) is the most common degenerative joint disease and involves the loss of articular cartilage integrity, formation of articular osteophytes, remodeling of subchondral bone, and synovitis. Knockdown of receptor interacting serine/threonine kinase (RIPK) 1 leads to anti-inflammatory and anti-apoptotic effects. However, the involvement of RIPK1 in the pathogenesis of OA is unclear.

Peimine suppresses interleukin‑1β‑induced inflammation via MAPK downregulation in chondrocytes.

Osteoarthritis (OA) is the most common type of degenerative joint disease and secreted inflammatory molecules serve a pivotal role in it. Peimine has been reported to have anti‑inflammatory activity. In order to investigate the potential therapeutic role of Peimine in OA, mouse articular chondrocytes were treated with IL‑1β and different doses of Peimine in vitro.

Necrostatin-1 Attenuates Trauma-Induced Mouse Osteoarthritis and IL-1β Induced Apoptosis via HMGB1/TLR4/SDF-1 in Primary Mouse Chondrocytes.

Necrostatin-1 (Nec-1) is a specific small molecule inhibitor of receptor-interacting protein kinase 1 (RIPK1) that specifically inhibits phosphorylation of RIPK1. RIPK1 regulates inflammation and cell death by interacting with receptor-interacting serine/threonine protein kinases 3(RIPK3). We hypothesized that Nec-1 may have anti-inflammatory efficacy in patients with osteoarthritis (OA), as the pathophysiology of OA involves the activation of inflammation-related signaling pathways and apoptosis.

Boldine Ameliorates Estrogen Deficiency-Induced Bone Loss via Inhibiting Bone Resorption.

Osteoporosis is an enormous health problem caused by the imbalance between bone resorption and bone formation. The current therapeutic strategies for osteoporosis still have some limitations. Boldine, an alkaloid isolated from , has been shown to have antioxidant and anti-inflammatory effects .

Identification of Skt11-regulated genes in chondrocytes by integrated bioinformatics analysis.

SKT11, an important tumor suppressor, is a member of the serine/threonine kinase family and plays a crucial role in tumor invasion and metastasis by activated adenine monophosphate-activated protein kinase (AMPK) and AMPK-related kinase proteins. However, few studies have elaborated its regulations of development and metabolism of cartilage, as well as skeleton. This study was aimed to investigate the role of Stk11-knockout in chondrocyte by bioinformatics analysis.

FNDC4 Inhibits RANKL-Induced Osteoclast Formation by Suppressing NF-B Activation and CXCL10 Expression.

FNDC4 acts as an anti-inflammatory factor on macrophages and improves mouse model of induced colitis. Considering osteoclast formation is characterized by the activation of inflammation-related pathways, we thus speculated that FNDC4 may play a pivotal role in this process. RT-qPCR analysis was performed to confirm the expression of osteoclast formation related genes in primary murine bone marrow macrophages (BMMs).

Peroxisome proliferator‑activated receptor γ agonist rosiglitazone inhibits migration and invasion of prostate cancer cells through inhibition of the CXCR4/CXCL12 axis.

It has been indicated that the C‑X‑C chemokine receptor type 4/C‑X‑C chemokine ligand 12 (CXCR4/CXCL12) axis is involved in promoting invasion and metastasis in tumors. Therefore, novel drugs capable of downregulating the CXCR4/CXCL12 axis may demonstrate potential for the treatment of metastatic prostate cancer (PCa). Rosiglitazone (RSG), a thiazolidinedione ligand of the peroxisome proliferator‑activated receptor (PPAR) γ, has been found to inhibit proliferation, induce apoptosis, suppress angiogenesis and inhibit metastasis.

Peroxisome proliferator-activated receptor γ ligands inhibit VEGF-mediated vasculogenic mimicry of prostate cancer through the AKT signaling pathway.

Vasculogenic mimicry (VM) describes functional vascular channels composed only of tumor cells and its presence predicts a poor prognosis for patients with prostate cancer. The present study demonstrated that prostate cancer PC-3 cells were able to form a patterned matrix or tubular VM in 3D cultures in vitro and rosiglitazone (RSG), the ligand of peroxisome proliferator-activated receptor γ (PPARγ) and effectively inhibited the formation of VM structures in a dose- and PPARγ‑dependent manner. In addition, RSG significantly inhibited prostate cancer cell migration and invasion.
