Article Abstract
Neuroimaging studies have found significant structural alterations of the cerebral cortex in patients with nasopharyngeal carcinoma (NPC) following radiotherapy (RT) or concomitant chemoradiotherapy (CCRT), while their effects on the shape of subcortical structures remain largely unknown. In this study, we investigated the subcortical shape alterations between three groups: 56 untreated NPC patients (pre-RT group), 37 RT-treated NPC patients (post-RT group), and 108 CCRT-treated NPC patients (post-CCRT group). Using FSL-FIRST, we found that, compared with the pre-RT group, the post-CCRT group exhibited significant inward atrophy in the bilateral thalamus, bilateral putamen, left pallidum, and left caudate and outward inflation in the left caudate, while the post-RT group only exhibited inward atrophy in the bilateral thalamus. In addition, greater maximum dosage of RT for temporal lobes was associated with more severe inward atrophy of the bilateral thalamus in treated NPC patients. These results indicated that there may be an interaction between RT and CT that can cause subcortical damage.

TMBquant: an explainable AI-powered caller advancing tumor mutation burden quantification across heterogeneous samples.
Brief Bioinform

Accurate tumor mutation burden (TMB) quantification is critical for immunotherapy stratification, yet remains challenging due to variability across sequencing platforms, tumor heterogeneity, and variant calling pipelines. Here, we introduce TMBquant, an explainable AI-powered caller designed to optimize TMB estimation through dynamic feature selection, ensemble learning, and automated strategy adaptation. Built upon the H2O AutoML framework, TMBquant integrates variant features, minimizes classification errors, and enhances both accuracy and stability across diverse datasets.

Inhibition of the NLRP3 inflammasome has emerged as a high potential treatment paradigm for the treatment of neuroinflammation, with demonstrated anti-neuroinflammatory effects in Parkinson's disease patients and a strong rationale in Alzheimer's disease and amyotrophic lateral sclerosis. To facilitate further progress in this field, brain penetrant NLRP3 inflammasome inhibitors as leads and tool compounds are required. We discovered a small molecule NLRP3 inflammasome inhibitor, NT-0527 (11), and extensively profiled this to reveal a highly potent, selective and brain penetrant compound.

Title: Can Radiotherapy Quality Assurance (RT QA) improve nasopharyngeal cancer (NPC) outcomes in low- and middle-income countries (LMICs) -Reporting phase 2 of a prospective International Atomic Energy Agency (IAEA) study (E33039).
Background: Most of new NPC cases occur in LMICs, but these patients experience poorer survival than new NPC cases in high income countries. This study seeks to determine whether a radiotherapy quality assurance (RT QA) programme can improve NPC patient outcomes in LMICs.
Regional Transcriptomic Architecture of Glioblastoma Reveals NUCB2 as a Key Orchestrator of Tumour Aggression and Immune Dysfunction.

Glioblastoma (GBM) exhibits remarkable intra-tumoral heterogeneity, which contributes to therapeutic resistance and poor clinical outcomes. In this study, we employed integrative single-cell RNA sequencing analysis across two complementary public datasets encompassing diverse cellular populations from GBM centre and periphery regions to elucidate potential spatial molecular programmes driving tumour progression. Our analyses revealed substantial transcriptomic divergence between anatomically distinct tumour regions, with NUCB2 emerging as significantly upregulated in centre-residing neural progenitor cell-like (NPC-like) tumour cells.

Background: Locally advanced nasopharyngeal carcinoma (LA-NPC) has a heterogeneous prognosis, with approximately one-fourth of patients experiencing poor outcomes. Studies have explored the application of induction chemoimmunotherapy followed by chemoradiotherapy, but its efficacy was controversial.
Methods: The protocol was registered in the Prospective Register of Systematic Reviews (PROSPERO, CRD42024619387).
