IDH1 mutation

At the network level, physiological PPIs exhibit high shared ncRNA buffering capacity, whereas oncogenic interactions are characterized by reduced or absent RNA overlap. AlphaFold3 modelling of mutant IDH1/2 complexes illustrates how loss of RNA buffering permits excessive stabilization of enzyme-associated interfaces, reflected by directional changes in buried surface area (ΔBSA) and contact heterogeneity.

Olutasidenib was well tolerated and conferred disease control in cCS. Study limitations include open-label design and low patient sample due to rarity of cCS.

This review focuses on contemporary pharmacotherapeutic approaches used in the management of glioblastoma, IDH-wildtype, including temozolomide-based chemotherapy, corticosteroids for edema control, and antiangiogenic therapy in recurrent disease, with particular emphasis on their clinical efficacy and limitations...Particular attention is given to ivosidenib, a selective inhibitor of mutant IDH1, currently evaluated for the treatment of astrocytoma, IDH-mutant, grade 4...Finally, innovative drug-delivery technologies designed to overcome the blood-brain barrier are briefly discussed as complementary strategies that may enhance the efficacy of both conventional and targeted therapies. Overall, future advances in the treatment of diffuse gliomas will likely depend on the integration of molecularly targeted agents, predictive biomarkers, and advanced delivery platforms aimed at improving patient survival and quality of life.

The patient was treated with combined chemotherapy and immunotherapy, showing stable disease at three-month follow-up. This case highlights the importance of vigilant long-term surveillance in NF1 patients and the role of molecular profiling in guiding personalized therapeutic strategies.

The DTI-ALPS index provides valuable insights into glymphatic dysfunction in brain tumours. This study underscores its potential as a non-invasive biomarker in differentiating these tumour groups.

Using these models, we tracked clonal evolution under selective pressure from IDH inhibitors and combination therapies, identifying an association between WT1 mutations and ivosidenib (IDH1 inhibitor) monotherapy resistance, as well as an antagonism between ivosidenib and enasidenib (IDH2 inhibitor) when tested in IDH1-mutated cells. Our findings demonstrate how single-cell proteogenomic analysis of PDX models can illuminate drug resistance mechanisms and inform therapeutic strategies.

We highlight the importance of incorporating molecular methods to improve diagnostic accuracy and achieve personalized treatments for gliomas, as proposed by the current 2021 WHO CNS 5 tumor classification guidelines. Performing new studies with larger patient cohorts integrating clinical data is necessary to determine the behavior, epidemiology, and therapeutic outcomes of this type of tumor more comprehensively.

This review compared the efficacy and safety of low-dose cytarabine (LDAC), azacitidine (AZA), 5- and 10-day decitabine (DEC), and gemtuzumab ozogamicin, alone or combined with drugs such as venetoclax (VEN), in older adults with AML ineligible for conventional chemotherapy. Treatment decisions should consider patient goals and functional status. These findings informed eight recommendations in updated ASH-AML guidelines.

Molecular testing has become an essential component of modern iCCA management. Broad, early, and technically integrated molecular profiling-ideally performed at initial diagnosis and interpreted in an interdisciplinary (molecular) tumor board-is critical to fully realize the potential of precision oncology in BTC.

Interestingly, C269 autopalmitoylation occurs within a hydrophobic pocket, targeted by a clinical IDH1-mutant inhibitor (LY3410738). Our study reveals that autopalmitoylation, conferred by the IDH1R132H mutation, links fatty acid metabolism to the regulation of IDH1 mutant activity and represents a druggable vulnerability in IDH1-mutant cancers.
