Gliomas, particularly glioblastoma (GBM), are the most common and aggressive primary brain tumors in adults, characterized by high malignancy frequent recurrence. Despite standard treatments, including surgery, radiotherapy, chemotherapy, prognosis for GBM remains poor, with a median survival of less than 15 months five-year rate below 10%. Tumor heterogeneity resistance to treatment create significant challenges controlling glioma progression. Therefore, there is an urgent need new therapeutic targets strategies.

The metabolism of stearoyl-GPE plays a key role in the liver metastasis gastric cancer. This investigation delves into mechanisms underlying intricate tumor microenvironment (TME) heterogeneity triggered by stearoyl cancer with (LMGC), offering novel perspectives for LMGC. Utilizing Mendelian randomization, we determined that significantly contributes to progression (GC). Following this, bulk transcriptome analyses and single-cell multiomics techniques investigate roles metabolism-related genes, particularly NCOA4, regulating LMGC TME. Our analysis highlights crucial modulating complex LMGC, impacting monocyte cells. Through sequencing spatial transcriptomics, have identified metabolic genes specific within cell population, including NCOA4. Regarding relationship between ferroptosis, metabolism, findings, it is plausible pathways intersect involved ferroptosis. Ferroptosis, characterized iron-dependent lipid peroxidation, represents regulated form death. activity Stearoyl-CoA desaturase (SCD), critical enzyme has been associated modulation composition susceptibility Furthermore, integral cellular processes related oxidative stress both which are significant factors context study enhances understanding ferroptosis promoting its regulation heterogeneity. In addition, this deeper dynamics provides basis development better interventions combat metastasis.

Background Ubiquitination, a critical post-translational modification, plays pivotal role in regulating protein stability and activity, influencing various aspects of cancer development, including metabolic reprogramming, immune evasion, tumor progression. However, the specific ubiquitination hepatocellular carcinoma (HCC), particularly relation to microenvironment (TME), remains poorly understood. This study aims systematically explore shaping TME HCC, with focus on its impact progression modulation. Methods We performed bioinformatics analysis by integrating multiple publicly available HCC datasets assess status across cell types TME, plasma cells, fibroblasts, endothelial epithelial-mesenchymal transition (EMT) cells. Ubiquitination scores were calculated categorize these types, survival data, along spatial transcriptomics, employed evaluate how different levels influence In vitro experiments, such as transwell, CCK8, wound healing assays, used further investigate key gene UBE2C phenotypes. Results Our revealed that ubiquitination-related genes are significantly upregulated tissues, high expression correlating poor prognosis patients. Pathway showed enriched processes cycle regulation, DNA repair, p53 signaling. These pathways contribute promoting proliferation, facilitating matrix remodeling, enhancing angiogenesis. Notably, UBE2C, enzyme, appears play potentially inhibiting anti-tumor responses reducing system’s ability recognize eliminate Furthermore, experimental data confirmed overexpression promotes invasion, metastasis, supporting remodeling. Conclusion reveals multifaceted regulatory roles HCC. not only supports proliferation anti-apoptotic functions within cells but also modulating activity stromal Among all genes, emerges potential prognostic biomarker therapeutic target offering new directions for precision treatment future.
