Использование естественных экзоцитозных везикул для борьбы с возрастными заболеваниями: от возрастных драйверов до терапевтических возможностей.

Старение — это сложный биологический процесс, приводящий к увеличению нагрузки возрастных заболеваний (ARD). Клеточная старость, включающая необратимое остановку клеточного цикла и выделение фенотипа секреторной активности при старении (SASP), играет центральную роль в старении и развитии ARD. Естественные экзоцитические везикулы (NEVs) — это везикулы, полученные из клеток, органов и тканей без искусственных вмешательств. В последние годы NEVs привлекли внимание как медиаторы межклеточной коммуникации, и показали многофункциональный потенциал в регулировании клеточной старости и ARD. С одной с

Полиненасыщенные жирные добавки к кислоте в системе управления множественным склерозом: обзор анализа.

Полиинунасыщенные жирные кислоты (PUFA) уже давно исследованы в качестве потенциальной адъюнктурной терапии множественных склерозов из-за их иммуномодулятивных, антивоспалительных и нейрозащитных свойств.

Radioprotectors & mitigators in radiation therapy: Harnessing diverse pathways for optimizing clinical outcomes.

Radioprotectors are agents that protect normal tissues from the harmful effects of radiation during cancer treatment. Combining these protective agents with advanced radiotherapy techniques such as stereotactic body radiotherapy (SBRT) and proton therapy offers a promising strategy to enhance therapeutic efficacy while minimizing normal tissue toxicity. However, despite extensive research and the identification of numerous potential radioprotectors, only a few have made it into clinical practice. It is primarily because the transition from laboratory research to clinical application faces sign

Rational drug repositioning for coronavirus-associated diseases using directional mapping and side-effect inference.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen of coronavirus disease 2019 (COVID-19), has infected hundreds of millions of people and caused millions of deaths. Looking for valid druggable targets with minimal side effects for the treatment of COVID-19 remains critical. After discovering host genes from multiscale omics data, we developed an end-to-end network method to investigate drug-host gene(s)-coronavirus (CoV) paths and the mechanism of action between the drug and the host factor in a directional network. We also inspected the potential side effect of the ca

Cancer, more than a "COVID-19 co-morbidity".

Patients with cancer represent a particularly vulnerable population at risk of adverse outcomes related to COVID-19. Collectively, the initial studies, including patients with and without cancer, confirmed that patients with cancer had a higher risk of complications and death related to COVID-19. Subsequent studies on patients with COVID-19 and cancer investigated patient and disease-related factors associated with COVID-19 severity and morality. Multiple interconnected factors include demographics, comorbidities, cancer-associated variables, treatment side effects, and other parameters. Howev

Amino acid metabolism in primary bone sarcomas.

Primary bone sarcomas, including osteosarcoma (OS) and Ewing sarcoma (ES), are aggressive tumors with peak incidence in childhood and adolescence. The intense standard treatment for these patients consists of combined surgery and/or radiation and maximal doses of chemotherapy; a regimen that has not seen improvement in decades. Like other tumor types, ES and OS are characterized by dysregulated cellular metabolism and a rewiring of metabolic pathways to support the biosynthetic demands of malignant growth. Not only are cancer cells characterized by Warburg metabolism, or aerobic glycolysis, bu

Different origin-derived exosomes and their clinical advantages in cancer therapy.

Exosomes, as a class of small extracellular vesicles closely related to the biological behavior of various types of tumors, are currently attracting research attention in cancer diagnosis and treatment. Regarding cancer diagnosis, the stability of their membrane structure and their wide distribution in body fluids render exosomes promising biomarkers. It is expected that exosome-based liquid biopsy will become an important tool for tumor diagnosis in the future. For cancer treatment, exosomes, as the "golden communicators" between cells, can be designed to deliver different drugs, aiming to ac

The Hypoxia-Retinoid Axis in Idiopathic Pulmonary Fibrosis: Multifaceted Etiology and Therapeutic Potential.

Idiopathic pulmonary fibrosis (IPF) is a progressive and lethal lung disease with limited therapeutic options. This review focuses on the role of retinoids, particularly all-trans retinoic acid (atRA), and hypoxia in the pathogenesis of IPF. Despite an established understanding of genetic and environmental factors in IPF, the interplay between retinoid signaling and the response to hypoxia remains poorly explored due to its complexity. Preclinical evidence suggests that atRA could help reduce pulmonary fibrosis by modulating TGF-β signaling pathways and epithelial-to-mesenchymal transition (EM

Decoding multiple myeloma: single-cell insights into tumor heterogeneity, immune dynamics, and disease progression.

BackgroundMultiple myeloma (MM) is a biologically heterogeneous malignancy of clonal plasma cells, often progressing from MGUS or smoldering MM. It causes anemia, bone lesions, and immune dysfunction due to abnormal plasma cell expansion in the bone marrow. Neuroinflammatory and neurotrophic factors may influence MM progression by affecting immune cells and the bone marrow niche. Growing evidence points to a role for neuroimmune regulation in tumor immunity. Despite therapeutic progress, disease heterogeneity and resistance highlight the need for new strategies targeting the tumor microenviron

Revisiting potential value of antitumor drugs in the treatment of COVID-19.

Since an outbreak started in China in 2019, coronavirus disease 2019 (COVID-19) has rapidly become a worldwide epidemic with high contagiousness and caused mass mortalities of infected cases around the world. Currently, available treatments for COVID-19, including supportive care, respiratory support and antiviral therapy, have shown limited efficacy. Thus, more effective therapeutic modalities are highly warranted. Drug repurposing, as an efficient strategy to explore a potential broader scope of the application of approved drugs beyond their original indications, accelerates the process of d

Nutritional approaches in combating therapeutic resistance and enhancing treatment efficacy in cancer: the impact of ketogenic diets.

Cancer remains a major global health challenge, with therapeutic resistance significantly limiting treatment success. Traditional approaches, including surgery, chemotherapy, and radiotherapy, often encounter barriers such as metastasis and adverse effects on healthy tissues. The Warburg effect, which describes cancer cells’ reliance on glucose fermentation despite oxygen availability, has prompted investigations into alternative metabolic interventions. The ketogenic diet (KD), characterized by high fat intake and low carbohydrate intake, induces a metabolic shift that may selectively disadva

Иммунометаболизм в старении мозга и нейродегенерации: преодоление метаболических путей и иммунные ответные меры.

Сложный набор взаимодействий между иммунной системой и метаболизмом, известный как иммунометаболизм, стал критическим регулятором последствий заболеваний в центральной нервной системе. В ходе многочисленных исследований метаболические расстройства увязывались с ослабленной иммунной реакцией при старении мозга, нейродегенеративных расстройствах и травме мозга. В этом обзоре мы обсудим вопрос о том, как нарушения баланса иммунометаболизма мозга способствуют патофизиологии дисфункции мозга. В первой части обзора резюмируется вклад таких критических групп иммунной клетки, как микроглии, астроциты,

Green Tea Catechins for Prostate Cancer Prevention: Present Achievements and Future Challenges.

Green tea catechins (GTCs) are a family of chemically related compounds usually classified as antioxidant molecules. Epidemiological evidences, supported by interventional studies, highlighted a more than promising role for GTCs in human prostate cancer (PCa) chemoprevention. In the last decades, many efforts have been made to gain new insights into the mechanism of action of GTCs. Now it is clear that GTCs' anticancer action can no longer be simplistically limited to their direct antioxidant/pro-oxidant properties. Recent contributions to the advancement of knowledge in this field have shown

Exosomes-loaded with traditional Chinese medicine constituents: a novel therapeutic avenue for aplastic anemia.

Aplastic anemia (AA) is a life-threatening blood disorder characterized by bone marrow failure and pancytopenia. Treatments such as immunosuppressive therapy (IST) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) have limitations, including poor long-term remission and donor shortages. Exosomes, nanosized extracellular vesicles, are promising drug delivery systems (DDS) due to their biocompatibility, targeted delivery, and capacity to penetrate biological barriers. Traditional Chinese medicine (TCM) regulates hematopoiesis and immunity but faces challenges with delivery. This

Targeting Sphingosine 1-Phosphate Metabolism as a Therapeutic Avenue for Prostate Cancer.

Prostate cancer (PC) is the second most common cancer in men worldwide. More than 65% of men diagnosed with PC are above 65. Patients with localized PC show high long-term survival, however with the disease progression into a metastatic form, it becomes incurable, even after strong radio- and/or chemotherapy. Sphingosine 1-phosphate (S1P) is a bioactive lipid that participates in all the steps of oncogenesis including tumor cell proliferation, survival, migration, invasion, and metastatic spread. The S1P-producing enzymes sphingosine kinases 1 and 2 (SK1 and SK2), and the S1P degrading enzyme
