The role of radiotherapy in patients with advanced melanoma failing targeted therapy

Acta Oncologica
Background and purpose: Approximately 50% of patients with metastatic melanoma harbor mutations in the BRAF gene, making them eligible for targeted therapy (TT). However, treatment options become limited once resistance develops.

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Genetic analysis of primary lung interdigitating dendritic cell sarcomas

The Journal of Pathology, EarlyView.
Abstract Interdigitating dendritic cell sarcomas (IDCSs) are rare tumors that commonly arise in the hematopoietic system and rarely outside. The genetic drivers of IDCS carcinogenesis are unknown; therefore, therapeutic options are limited. We investigated somatic gene mutations and copy‐number alterations (CNAs) in nine IDCSs arising in the lung by ...

Histiocytosis development and clinical variation through the lens of genomics

The Journal of Pathology, EarlyView.
Abstract Histiocytic neoplasms are rare haematologic diseases characterised by clonal expansions of cells with a monocyte, macrophage or dendritic cell phenotype. Their clinical manifestations are diverse, ranging from indolent lesions to aggressive systemic disease.

Generalizing the Gaussian Network Model: Spanning‐Tree Thermodynamics Shows Entropy‐Driven KRAS Activation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The GTPase KRAS executes a conformational switch between a GTP‐bound active state and a GDP‐bound inactive state, a process central to oncogenic signaling. However, the structural basis of this switching at the level of residue‐contact organization remains incompletely characterized by traditional binary structural models.

When flames hit the brain, and the spark is far away: the role of PET-CT in diagnosing neurological Erdheim-Chester disease

Arquivos de Neuro-Psiquiatria
Erdheim-Chester disease (ECD) is a rare histiocytic disorder that poses diagnostic and therapeutic challenges. Neurological manifestations are characterized by involvement of the meninges, brainstem, and/or cerebellum, and the differential diagnoses ...

Neutrophil extracellular traps induced by activated platelets as a cause of neutrophil–platelet aggregation in β‐thalassaemia/haemoglobin E patients

British Journal of Haematology, EarlyView.
Abnormal neutrophils and platelets in splenectomised β‐thalassaemia/haemoglobin E (HbE) disease contribute to neutrophil–platelet aggregation, leading to a high risk of thrombus formation. Activated platelets induce neutrophils to generate neutrophil extracellular trap (NETs) via the P‐selectin–P‐selectin glycoprotein ligand‐1 (PSGL1) pathway, which ...

Outcome of treatment with trametinib in adults with histiocytic neoplasms in the United Kingdom

British Journal of Haematology, EarlyView.
Trametinib (MEK inhibitor) shows efficacy in refractory and high‐risk adult histiocytic neoplasms. At a median follow‐up of 21.4 months, the clinical response rate was 81% (30/37) and the radiological response was 68% (25/37) (n = 37).

Dual pharmacological targeting of coactivator‐associated arginine methyltransferase 1 (CARM1) and salt inducible kinase (SIK) drives ketogenesis in both hepatocytes and mice

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ketone bodies are liver‐derived circulating energy metabolites that positively impact most hallmarks of ageing. Ketone bodies increase during calorie restriction and fasting, two of the more widely perceived methods to increase health span.
