AI Article Synopsis
- Osteoarthritis (OA) is the most prevalent form of arthritis, particularly affecting the elderly and leading to significant physical disability due to joint pain and stiffness.
- Key pathological features of OA include chondrocyte death and degradation of articular cartilage, with current treatments like NSAIDs having limited effectiveness in halting disease progression.
- Recent research highlights ferroptosis, a specific type of cell death caused by iron-related processes, as a potential factor in chondrocyte loss in OA, suggesting that inhibiting this process could offer new therapeutic options.
Article Abstract
Osteoarthritis (OA) is the most common type of arthritis. Its high prevalence, especially in the elderly, and its negative impact on physical function make it a leading cause of disability in the elderly. Joint pain as well joint stiffness are the common classic signs of OA. Chondrocyte death together with loss of articular cartilage integrity are the main pathologic changes in OA. Non-steroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids are commonly used for the management of OA; still, their effectiveness is limited, and no therapeutic strategy is able to fully stop OA progression. Ferroptosis is a kind of cell death, distinct from apoptosis and necroptosis, caused by iron-dependent peroxidation of membrane phospholipids that terminates cell life by disintegrating all plasma membranes. It has been suggested that ferroptosis has a critical role in decreased viability of chondrocytes in OA, and here, we review recent findings regarding the pathologic pathways that lead to chondrocyte ferroptosis, and discuss the possible therapeutic utility of ferroptosis inhibition in OA.

Objective: To screen potential differentially expressed genes related to immune function in nasopharyngeal carcinoma through an online database, and to verify their mechanism of action, so as to provide a reference for the diagnosis and treatment of nasopharyngeal carcinoma in the future.
Methods: Differentially expressed genes were analyzed from the GSE227541 dataset, and functional enrichment analysis was conducted. With mucin 5B, oligomeric mucus/gel-forming as the focus, the correlation between its expression and immune indexes was analyzed by using the TIMER database.

Introduction: Osteoarthritis (OA) is a chronic degenerative joint disorder characterized by an imbalance in chondrocyte metabolism. Ferroptosis has been implicated in the pathogenesis of OA. The role of Sirt1, a deacetylase, in mediating deacetylation during ferroptosis in OA chondrocytes remains underexplored.

Cancer remains one of the most formidable challenges in the medical field in this century, largely due to its poorly understood pathogenesis. Fortunately, recent advancements in the understanding of cancer pathogenesis have helped identify more therapeutic targets for improved treatment outcomes. The WNT signaling pathways are highly conserved cascades that participate in diverse physiological processes, such as embryonic development, tissue homeostasis, and tissue regeneration.

Background: The interplaying neuropathology of amyloid plaque, tau tangles, and microglia-driven inflammation (tri-pathology) are related to neuronal and synaptic loss damage in Alzheimer's damages. Interventions that target Aβ or tau individually have not yielded substantial breakthroughs. Iron plays a pivotal role in tri-pathology by protein-bound iron-oxide deposition in amyloid plaque, tau tangle, and microglia, resulting in redox-active toxicity or microglial response induction, such as proinflammatory activation, autophagy dysfunction, and ferroptosis.

Background: Lung adenocarcinoma is the most common form of lung cancer and one of the most life-threatening malignant tumors. Ferroptosis is an iron-dependent regulatory cell death pathway that is crucial for tumor growth. SNX30 is a key regulatory factor in cardiac development; however, its regulatory mechanism and role in inducing ferroptosis in lung adenocarcinoma remain unclear.
