We predicted potential therapeutic small molecular drugs by targeting subtype-specific oncogenic pathways and validated drug sensitivity (C1-GBM: Methotrexate and Cisplatin; C2-GBM: Cytarabine) by assessing IC50 values against GBM cell lines (divided into C1/C2 subtypes based on the nine hub genes) from the Genomics of Drug Sensitivity in Cancer database. This study introduces a pathway-based prognostic molecular classification of GBM with "hot" (C1-GBM) and "inherent driving" (C2-GBM) tumor subtypes, providing a prediction model based on hub biomarkers and potential therapeutic targets for treatments.

This study presents a method to improve the therapeutic effect of methotrexate against rheumatoid arthritis using the Exo/MTX/HA.

In this prospective, randomized, open-label, single-center study, 76 children with non-systemic JIA in stable remission for ≥24 months on etanercept or adalimumab were enrolled. Early significant clinical response, absence of subclinical disease activity, and concomitant low-dose methotrexate therapy were key predictors of sustained drug-free remission. These findings may inform personalized strategies for biologic tapering in pediatric JIA.

In the pre-biologic era, immunomodulators such as azathioprine, 6-mercaptopurine, and methotrexate (MTX) were widely used as first-line maintenance therapies in Crohn's disease. In light of evolving treatment goals that prioritize safety, cost-effectiveness, and individualized care, this editorial argues that MTX should no longer be viewed as a fallback but as a strategic first-line option in well-defined high-risk populations. The survey underscores a persistent gap between guidelines and real-world practice, reinforcing the urgent need for clearer algorithms and education to support the repositioning of MTX in modern Crohn's disease management.

Rats were randomly divided into five groups: healthy control (Control), untreated RA model (Model), SIL (25 mg/kg/day), SIL (50 mg/kg/day), and methotrexate (7.6 mg/kg/day) groups, with 10 mice in each group...SIL effectively mitigates myocardial fibrosis and oxidative stress in adjuvant-induced RA rats, primarily through inhibition of IRAK4-mediated inflammatory signaling. These findings highlight SIL as a promising therapeutic candidate for RA-related cardiac injury.

Collectively, our findings uncover that METTL3-mediated m6A modification of CACNA1E contributes to OS progression and chemoresistance through enhancing WNT7B-mediated non-canonical Wnt/Ca2+ signaling. Targeted inhibition of CACNA1E in combination with MTX may be a promising alternative therapeutic strategy for patients with MTX-resistant OS.

CAEO considerably alleviated the oxidative and nitrosative stress, mitochondrial dysfunction, inflammatory and apoptosis responses caused by MTX. This shielding effect may be due to the decline in JAK2/STAT3/NF-κB and the triggering in Nrf2/HO-1/NQO1 pathways.

The congruence between bioinformatics and experimental validation findings strongly highlighted API as a promising therapeutic candidate for alleviating METX cardiotoxicity. While the current data reveals key underlying molecular mechanisms for API's cardioprotective effect, further comprehensive studies across diverse cardiotoxicity models are essential to fully elucidate cardioprotective effect of API.

He was started on levetiracetam for a first-time seizure and discharged...Two weeks later, high-dose methotrexate plus cytarabine was initiated, with neurological improvement...Computed tomography (CT) showed no new intracranial findings, but pancytopenia and cultures positive for carbapenem-resistant Citrobacter freundii were identified, and he died of septic shock. This case illustrates that CNS ALCL can radiographically mimic metastatic disease, underscores the necessity of tissue diagnosis, and highlights the competing imperatives of timely intensive chemotherapy and rigorous infection surveillance, particularly for multidrug-resistant organisms in older adults with PCNSL.
