Nucleotide Metabolism in Health and Disease.

Nucleotide metabolism is a fundamental biochemical process, providing the building blocks for DNA and RNA synthesis while driving critical cellular functions like energy transfer, signal transduction, and coenzyme synthesis. The precise regulation of nucleotide de novo synthesis, salvage, and degradation pathways is imperative for maintaining genomic stability and tissue homeostasis. Aberrations in these networks are increasingly recognized as primary drivers in various pathologies; notably, cancer cells exploit metabolic-functional reprogramming to enable rapid proliferation and therapeutic r

Epithelial-Mesenchymal Transition in Cancer: Insights Into Therapeutic Targets and Clinical Implications.

Radiation therapy is a fundamental component of cancer treatment, benefiting 50%-70% of patients by selectively targeting malignant tissues. However, radioresistance remains a significant challenge, often driven by epithelial-mesenchymal transition (EMT). EMT increases cancer invasiveness and metastasis by upregulating mesenchymal markers, including vimentin and N-cadherin, and downregulating epithelial markers, such as E-cadherin. EMT under radiation involves principal signaling pathways, including TGF-β, Wnt/β-catenin, Notch, and ERK, which regulate EMT through transcription factors such as

Recurrent plasmacytomas after allografting in a patient with multiple myeloma.

Extramedullary recurrence in multiple myeloma patients has been reported after both autologous and allogeneic hematopoietic cell transplantation and, more recently, after treatment with so-called new drugs with potent antimyeloma activity. Only a very few sizable reports focused on its clinical presentation and its incidence, which may be highly underestimated, and most observations are based on single patients reported from several institutions. Given the unusual sites of recurrence, diagnosis may be rather difficult and delayed treatment may play a relevant role in prognosis. Here we report

Ex vivo drug response heterogeneity reveals personalized therapeutic strategies for patients with multiple myeloma.

Multiple myeloma (MM) is a plasma cell malignancy defined by complex genetics and extensive patient heterogeneity. Despite a growing arsenal of approved therapies, MM remains incurable and in need of guidelines to identify effective personalized treatments. Here, we survey the ex vivo drug and immunotherapy sensitivities across 101 bone marrow samples from 70 patients with MM using multiplexed immunofluorescence, automated microscopy and deep-learning-based single-cell phenotyping. Combined with sample-matched genetics, proteotyping and cytokine profiling, we map the molecular regulatory netwo

Biobehavioral Pathways and Cancer Progression: Insights for Improving Well-Being and Cancer Outcomes.

The relationship between psychosocial factors and cancer has intrigued people for centuries. In the last several decades there has been an expansion of mechanistic research that has revealed insights regarding how stress activates neuroendocrine stress-response systems to impact cancer progression. Here, we review emerging mechanistic findings on key pathways implicated in the effect of stress on cancer progression, including the cellular immune response, inflammation, angiogenesis, and metastasis, with a primary focus on the mediating role of the sympathetic nervous system. We discuss converg

Integrative meta-analysis identifies microRNA-regulated networks in infantile hemangioma.

BackgroundHemangioma is a common benign tumor in the childhood; however our knowledge about the molecular mechanisms of hemangioma development and progression are still limited. Currently, microRNAs (miRNAs) have been shown as gene expression regulators with an important role in disease pathogenesis. Our goals were to identify miRNA-mRNA expression networks associated with infantile hemangioma.MethodsWe performed a meta-analysis of previously published gene expression datasets including 98 hemangioma samples. Deregulated genes were further used to identify microRNAs as potential regulators of

From bench to bedside: the application of cannabidiol in glioma.

Glioma is the most common malignant tumor in central nervous system, with significant health burdens to patients. Due to the intrinsic characteristics of glioma and the lack of breakthroughs in treatment modalities, the prognosis for most patients remains poor. This results in a heavy psychological and financial load worldwide. In recent years, cannabidiol (CBD) has garnered widespread attention and research due to its anti-tumoral, anti-inflammatory, and neuroprotective properties. This review comprehensively summarizes the preclinical and clinical research on the use of CBD in glioma therapy

Beyond SINS: A Critical Review of Biomechanical, Microstructural, and Radiomic Biomarkers for Predicting Fracture Risk in Spinal Metastases

Background/Objectives: Although the Spinal Instability Neoplastic Score (SINS) is widely used to estimate spinal metastases fracture risk and guide decisions on stabilisation procedures, prior studies have demonstrated mixed results. Patients with the same score exhibit clinically heterogeneous outcomes, with some SINS criteria correlating less well with the estimated fracture risk than others. There are also barriers to implementation such as the time burden required for manual calculation and interobserver variability associated with qualitative morphological criteria. SINS also lacks sensit

Histone Deacetylase Inhibitors in Pediatric Brain Cancers: Biological Activities and Therapeutic Potential.

Brain cancers are the leading cause of cancer-related deaths in children. Biological changes in these tumors likely include epigenetic deregulation during embryonal development of the nervous system. Histone acetylation is one of the most widely investigated epigenetic processes, and histone deacetylase inhibitors (HDACis) are increasingly important candidate treatments in many cancer types. Here, we review advances in our understanding of how HDACis display antitumor effects in experimental models of specific pediatric brain tumor types, i.e., medulloblastoma (MB), ependymoma (EPN), pediatric

Chronic stress and myeloid immunosuppression in cancer: A neuroimmune link to behavioral dysfunction.

Cancer progression is profoundly influenced by the complex interplay between the tumor microenvironment (TME), the immune system, and the patient's psychological state. This review delineates a critical pathway linking chronic stress to worsened cancer outcomes through inflammatory factors, anti-tumor immune suppression, and the induction of behavioral comorbidities. We postulate that sustained stress hormone signaling via the sympathetic nervous system and hypothalamic-pituitary-adrenal axis activation orchestrates a systemic immunosuppressive cascade. A central mechanism is the stress-induce

Роль микроглии в синаптогенезе, синаптической и синаптической пластичности в физиологических условиях и в нарушениях центральной нервной системы.

Микроглии являются постоянными иммунными клетками мозга, которые были широко изучены для их иммунного наблюдения и фагоцитоза. В последние годы постепенно признается важная роль микроглии в синапсовом образовании, ликвидации и пластичности. Синапсы являются основным режимом связи между нейронами. Они постоянно меняются в количестве и пластичности на протяжении всего жизненного цикла, который является основой обучения и памяти. Микроглии являются сильно мотилированными, ветковыми формами, которые осуществляют мониторинг микроокружающей среды центральной нервной системы (КНС) и поощряют синапсов

Preclinical and Virtual Models of Mucosal Melanoma: Bridging Translational Gaps in a Rare and Lethal Cancer.

Mucosal melanoma (MM) is a rare and lethal subtype of melanoma, disproportionately affecting Asian populations and exhibiting distinct clinicopathological and genetic features compared to cutaneous melanoma (CM). Often diagnosed at advanced stages, MM shows poor responses to conventional therapies, and no standardized treatment regimen currently exists. Progress in preclinical modeling, including cell lines, patient-derived xenografts (PDXs), organoids (PDOs), and comparative animal models-has provided valuable tools for studying MM pathogenesis and therapeutic resistance. Yet these models rem

Myelin Displacement and Revention in the Central Nervous System: Молекулярные механизмы, болезни и перспективные терапевтические цели.

Майлин пластичность имеет основополагающее значение для формирования нейронных сетей и оптимизации нейронных функций, формирования схем, регулирующих эмоции, сознание, сенсацию и управление двигателем. Подкомбинированный олигодендроцитами, миелин подвергается пожизненной реконструкции, которая требует высокой метаболической активности; это делает миелин-олигодендроцитную единицу весьма восприимчивой к метаболическому стрессу, старению и патологическим оскорблениям. Хотя обезвоживание является основной характеристикой различных хронических неврологических расстройств, в настоящем обзоре особо п
