In recent times, disulfidptosis, an intricate form of cellular demise, has garnered attention due to its impact on prognosis, tumor progression and treatment response. Nevertheless, the exact significance disulfidptosis-related genes (DisRGs) in glioblastoma (GBM) remains enigmatic. The GEO TCGA databases provided transcriptional clinically relevant data samples, while GTEx database healthy tissues. Disulfidptosis-related were procured from previous scholarly investigations. expression profile DisRGs was initially scrutinized among patients diagnosed with GBM, subsequent which their prognostic value explored. Through consensus clustering, we constructed DisRGs-related clusters gene subtypes. Our results established that DisRG-related had differentially expressed genes, resulting a DisulfidptosisScore model, positive value. differential 24 between GBM samples acquired. cluster analysis, two distinct disulfidptosis subtypes, namely DisRGcluster A B, identified. Then, model including 4 characteristic constructed.Notably, assigned lower score demonstrated considerably longer overall survival (OS) compared those higher score. We have effectively devised associated presenting autonomous predictions for GBM. These findings serve as valuable addition current comprehension offer fresh theoretical substantiation development enhanced strategies.

ABSTRACT Disulfidptosis, a new form of programmed cell death, plays role in multiple types cancer. However, research on disulfidptosis glioma is lacking. A disulfidptosis‐associated risk score was constructed using Cox regression modelling, while LASSO applied for feature selection. To explore the relationship between and immune microenvironment, we employed CIBERSORT, ssGSEA ESTIMATE algorithms. Additionally, wet lab experiments were conducted to validate functional key gene RPN1, demonstrating its ability promote proliferation migration. Disulfidptosis genes significantly upregulated gliomas, influencing clinical features survival. The effectively predicted OS varied among subgroups. High‐risk scores correlated with tumour growth, invasion immunosuppression. Patients different showed distinct infiltration patterns. Most checkpoints chemokines positively associated scores. Laboratory findings confirmed that RPN1 promoted Disulfidptosis‐based assessment stratifies prognosis reveals microenvironment characteristics, offering insights personalised treatment strategies.

Programmed cell death is pivotal for several physiological processes, including immune defense. Further, it has been implicated in the pathogenesis of developmental disorders and onset numerous diseases. Multiple modes programmed death, apoptosis, pyroptosis, necroptosis, ferroptosis, have identified, each with their own unique characteristics biological implications. In February 2023, Liu Xiaoguang his team discovered "disulfidptosis," a novel pathway death. Their findings demonstrated that disulfidptosis triggered glucose-starved cells exhibiting high expression protein called SLC7A11. Furthermore, marked by drastic imbalance NADPH/NADP+ ratio abnormal accumulation disulfides like cystine.
