Orthopedic diseases, such as degenerative conditions including intervertebral disc degeneration, osteoporosis, osteoarthritis, and malignant bone tumors like osteosarcoma, all involve imbalances in the immunometabolic microenvironment. The triggering conditions for disulfidptosis, such as high expression of SLC7A11 and glucose deprivation, are highly correlated with the pathaological features of orthopedic diseases and associated immune dysregulation. However, there is currently a lack of systematic understanding regarding the regulatory networks, molecular markers, and intervention strategies of disulfidptosis in orthopedic diseases, and the specific mechanisms by which it contributes to disease onset and progression remain unclear. This review systematically summarizes the bidirectional immunometabolic regulatory molecular mechanisms, pathological associations, and potential therapeutic strategies of disulfidptosis in orthopedic degenerative diseases and bone tumors. By analyzing the immunometabolic regulatory networks of key molecules such as SLC7A11, TXNRD1, and RPN1, we propose immune-aware precision strategies combining disulfidptosis-targeted metabolic intervention with checkpoint blockade immunotherapy.

Understanding the mechanisms driving tumor growth and metastasis in gastric cancer is essential for the development of effective therapeutic strategies. In this regard, it is well-established that CD200, a glycoprotein that binds to the CD200 receptor, has notable immunosuppressive effects. The extracellular domain of CD200 is secreted into the tumor microenvironment (TME), wherein it promotes cancer progression. However, although CD200 is highly expressed in several types of cancers, the details of its intracellular roles in tumor progression remain poorly understood. In this study, we investigated the biological function and mechanism of action of CD200 in gastric cancer. Public datasets from GSE and TCGA revealed that CD200 is overexpressed in gastric cancer and that its expression is correlated with cancer stage and metastasis. Functionally, we found that CD200 enhances cell proliferation, migration, and invasion, and also promotes the expression of epithelial-mesenchymal transition (EMT)-related genes. Mechanistically, CD200 was demonstrated activate the WNT/β-catenin signaling pathway by inducing β-catenin activation. Notably, we established that the cytoplasmic domain of CD200 binds directly to β-catenin, thereby facilitating its nuclear translocation. The CD200/β-catenin/TCF4 complex subsequently promotes the transcription of β-catenin target and EMT-related genes. Collectively, our findings in this study revealed that the cytoplasmic domain of CD200 interacts with β-catenin, thereby promoting the transcriptional activation of β-catenin target genes and inducing tumor growth and metastasis in gastric cancer.

The present study was intended to verify classic markers of senescence, like senescence-associated ß-galactosidase and the development of a senescence-associated secretory phenotype among fibroblasts during emerging senescence. The application of an in vitro model using serial passaging as inducer of replicative senescence revealed specific differences of a non-senescent and a pre-senescent fibroblast phenotype in mono-cultures, representing the basis for a detailed examination of the phenotypes in their interaction with microvascular endothelial cells in co-cultures. The results deliver new insights into the age dependent process of tissue repair. Characteristics of pre-senescent fibroblasts in terms of modified proliferation, cell morphology, cell cycle regulation, myofibroblastoid differentiation and cytokine release indicate a strong responsibility of this phenotype for the composition and function of a granulation tissue at different locations, including vascular sites.

In the underperfused heart, acid disturbances are often accompanied by hypoxia, but their interplay on cardiac NBC activity is unknown.

In contrast, pH<sub>i</sub>-sensitivity of NBC flux was increased after long-term hypoxia, likely an adaptive response. This increase was not due to buffering capacity changes but was mimicked by dimethyloxalylglycine (1 mM, DMOG), which stabilizes hypoxia inducible factor under normoxic conditions. Hypoxia affected neither NBCn1 nor NBCe1 protein levels, indicating a modulatory effect on transporter activity. The contribution of electrogenic (NBCe1) and electroneutral (NBCn1) isoforms, dissected from fluxes generated under hyperkalemia, showed that long-term hypoxia selectively raised NBCn1 activity.
