Aging modulation of the immune system and immunotherapy efficacy in cancer.

Immunosenescence is characterized by immune decline and chronic inflammation. With advancing age, the incidence of tumors increases significantly. Understanding how immunosenescence influences the initiation and progression of tumors, as well as its implications for tumor immunotherapy, has become a matter of urgent importance. This review begins with an analysis of the phenotypic changes and underlying mechanisms associated with immune system and immune cell aging, and further explores the interplay between immunosenescence and tumorigenesis. Evidence indicates that cytokines, cell interactio

Chimeric Antigen Receptor T Cells as Living Therapeutics Targeting Senescence and Age-Related Diseases.

The aging of the global population exacerbates the burden of age-related diseases; however, therapies that can intervene in fundamental aging processes are lacking. Senescent cells drive chronic inflammation and multitissue dysfunction through the secretion of proinflammatory and profibrotic senescence-associated secretory phenotype cells, making them emerging therapeutic targets. Although first-generation senolytic drugs have entered clinical trials, they face limitations such as insufficient targeting specificity and transient efficacy. The success of chimeric antigen receptor T cell (CAR T

Non-coding RNA/microRNA-modulatory dietary factors and natural products for improved cancer therapy and prevention: Alkaloids, organosulfur compounds, aliphatic carboxylic acids and water-soluble vitamins.

Non-coding small RNA molecules, the microRNAs (miRNAs), contribute decisively to the epigenetic regulation processes in cancer cells. Problematic pathogenic properties of cancer cells and the response of cancers towards anticancer drugs are highly influenced by miRNAs. Both increased drug activity and formation of tumor resistance are regulated by miRNAs. Further to this, the survival and proliferation of cancer cells and the formation of metastases is based on the modulated expression of certain miRNAs. In particular, drug-resistant cancer stem-like cells (CSCs) depend on the presence and abs

Pro-inflammatory Cytokines, Ferroptosis, and Cancer.

Ferroptosis, iron-dependent regulated cell death, is induced by the polyunsaturated fatty acid peroxidation of membrane phospholipids and is controlled by glutathione peroxidase 4. In recent years, convincing evidence has emerged, demonstrating a close relationship between chemo-, radio-, immuno-, and targeted therapy resistance and ferroptosis resistance. In this review, we discuss the basic principles of ferroptosis in cancer. Considerable attention is paid to the formation of an immunosuppressive tumor microenvironment. The main focus is centered on the involvement of the excessive, chronic

Comprehensive understanding of the adverse effects associated with temozolomide: a disproportionate analysis based on the FAERS database.

BACKGROUND: Temozolomide, which is the standard drug for glioma treatment, has several Adverse events (AEs) in the treatment of gliomas and other tumors that are not yet fully understood. This is due to the pharmacological nature of the alkylating agent. A significant proportion of these effects have not been systematically documented or reported. METHODS: We selected data from the United States FDA Adverse Event Reporting System (FAERS) database from the first quarter of 2004 to the fourth quarter of 2023. Four algorithms were used for disproportionate analysis, with the objective of assessi

Biomarkers of Chemotherapy-Induced Peripheral Neuropathy: Current Status and Future Directions.

Chemotherapy induced peripheral neuropathy (CIPN) is an often severe and debilitating complication of multiple chemotherapeutic agents that can affect patients of all ages, across cancer diagnoses. CIPN can persist post-therapy, and significantly impact the health and quality of life of cancer survivors. Identifying patients at risk for CIPN is challenging due to the lack of standardized objective measures to assess for CIPN. Furthermore, there are no approved preventative treatments for CIPN, and therapeutic options for CIPN remain limited once it develops. Biomarkers of CIPN have been studie

The biology of stress in cancer: Applying the biobehavioral framework to adolescent and young adult oncology research.

The stress response influences the development and trajectory of cancer through a host of complex neuroimmune mechanisms. Basic, translational, and clinical research has elucidated these biobehavioral connections and offers a new paradigm for scientific investigation and patient care. Using a biobehavioral approach could offer new diagnostic and therapeutic opportunities in oncology, and this approach will be particularly impactful for adolescent and young adult (AYA) patients with cancer. To date, nearly all biobehavioral oncology research has been done in the adult population. And yet, AYAs

Poly(ADP-Ribose) Polymerase Inhibitors in Pancreatic Cancer: A New Treatment Paradigms and Future Implications.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy. Most of the patients of PDAC present at later stages of disease and have a five-year survival rate of less than 10%. About 5-10% PDAC cases are hereditary in nature and have DNA damage repair (DDR) mutations such as BRCA 1 and 2. Besides having implications on screening and prevention strategies, these mutations can confer sensitivity to platinum-based therapies and determine eligibility for poly(ADP-ribose) polymerase inhibitors (PARPi). In the presence of DDR mutations and PARPi, the cells are unable to utilize the error-fr

… Identification of acquired resistance mutations in circulating tumor DNA (ctDNA), collected during or after platinum induction, can be helpful. Based on available data, patients with BRCA2 reversion mutations should not be treated with PARPi maintenance; rather, 5-FU maintenance should be selected. …

Beyond regulations at DNA levels: A review of epigenetic therapeutics targeting cancer stem cells.

In the past few years, the paramount role of cancer stem cells (CSCs), in terms of cancer initiation, proliferation, metastasis, invasion and chemoresistance, has been revealed by accumulating studies. However, this level of cellular plasticity cannot be entirely explained by genetic mutations. Research on epigenetic modifications as a complementary explanation for the properties of CSCs has been increasing over the past several years. Notably, therapeutic strategies are currently being developed in an effort to reverse aberrant epigenetic alterations using specific chemical inhibitors. In thi

Advancing cancer therapy: Nanomaterial-based encapsulation strategies for enhanced delivery and efficacy of curcumin.

Curcumin, a polyphenolic compound derived from Curcuma longa, has gained significant attention as a potential anticancer agent due to its anti-inflammatory, antioxidant, and antitumor properties. Despite its therapeutic potential, the clinical application of curcumin is limited by its poor aqueous solubility, rapid metabolism, and limited bioavailability. To address these limitations, various nanomaterial-based encapsulation strategies have been developed, including polymeric nanoparticles, liposomes, solid lipid nanoparticles, micelles, dendrimers, and hybrid nanomaterials. These formulations

Cancer stem cells: advances in knowledge and implications for cancer therapy.

Cancer stem cells (CSCs), a small subset of cells in tumors that are characterized by self-renewal and continuous proliferation, lead to tumorigenesis, metastasis, and maintain tumor heterogeneity. Cancer continues to be a significant global disease burden. In the past, surgery, radiotherapy, and chemotherapy were the main cancer treatments. The technology of cancer treatments continues to develop and advance, and the emergence of targeted therapy, and immunotherapy provides more options for patients to a certain extent. However, the limitations of efficacy and treatment resistance are still i

PLP2 Could Be a Prognostic Biomarker and Potential Treatment Target in Glioblastoma Multiforme.

ObjectiveThis study aimed to discern the association between PLP2 expression, its biological significance, and the extent of immune infiltration in human GBM.MethodsUtilizing the GEPIA2 and TCGA databases, we contrasted the expression levels of PLP2 in GBM against normal tissue. We utilized GEPIA2 and LinkedOmics for survival analysis, recognized genes co-expressed with PLP2 via cBioPortal and GEPIA2, and implemented GO and KEGG analyses. The STRING database facilitated the construction of protein-protein interaction networks. We evaluated the relationship of PLP2 with tumor immune infiltrates

Machine Learning: A New Prospect in Multi-Omics Data Analysis of Cancer.

Cancer is defined as a large group of diseases that is associated with abnormal cell growth, uncontrollable cell division, and may tend to impinge on other tissues of the body by different mechanisms through metastasis. What makes cancer so important is that the cancer incidence rate is growing worldwide which can have major health, economic, and even social impacts on both patients and the governments. Thereby, the early cancer prognosis, diagnosis, and treatment can play a crucial role at the front line of combating cancer. The onset and progression of cancer can occur under the influence of

Сопротивление лекарствам в Множественной миеломе: опухоль-интринтические механизмы и микроокружающая среда костного мозга.

Множественная миелома (ММ) — злокачественное расстройство плазменных клеток, и, несмотря на значительные улучшения в прогнозе, полученные благодаря химиотерапии, иммунной терапии и автологической трансплантации стволовых клеток, у большинства пациентов в конечном счете возникает рецидив или рефракторное заболевание. Сопротивление лекарствам (DR) все чаще признается как динамическо развивающаяся экосистема, формируемая из опухоли-интенсивной пластичности и непрерывной реконструкцией микроокружающей среды костного мозга (BMME), а не как одно молекулярное повреждение. В настоящем обзоре резюмирую

Skeletal muscle dysfunction induced by cancer immunotherapy: mechanistics insights and surgical implications.

Cancer immunotherapy has revolutionized cancer treatment, yet its effects extend far beyond tumor eradication. Accumulating evidence indicates that immunotherapy-associated skeletal muscle dysfunction represents a complex, cross-organ pathological process driven by dynamic crosstalk between the tumor microenvironment and peripheral tissues. Rather than an isolated adverse event, muscle injury emerges from integrated mechanisms including inflammatory cytokine spillover, aberrant immune cell infiltration, metabolic reprogramming, vascular dysfunction, and impaired regenerative signaling. Central

Update on current pancreatic treatments: from molecular pathways to treatment.

Pancreatic cancer is still diagnosed at a late stage although we have novel diagnostic tools. Pancreatic cancer chemotherapy treatment resistance is observed and therefore novel treatments are in need. Anti-cancer stem cell therapy, combination of chemotherapy and/or radiotherapy with immunotherapy, proteins/enzymes and gene therapy are currently under evaluation. Targeted treatment with tyrosine kinase inhibitors is also administered and novel inhibitors are also under evaluation. In the current review we present recent data from our search within the year 2018.

Декодирование автономного иммунитета: распознает нейромиэлит оптику и ее связь с другими аутоиммунными неврологическими расстройствами.

Оптика нейромиелита (NMO) является редким, но изнурительным аутоиммунным заболеванием, характеризующимся сильным приступом оптического невравита и поперечного миелита, что часто приводит к значительным неврологическим расстройствам. Автоантиорганы, предназначенные для аквапорина-4 (AQP4) и миэлина олигодендроцита гликпротеина (MOG), играют важнейшую роль в патогенезе болезней, а терапевтические стратегии, включающие иммунодепрессивную терапию и новые биологи, используются для борьбы с заболеваниями и предотвращения рецидивов. Хотя исследования указывают на возможное дублирование между НМО и др

Circulating Exosomes Derived-miR-146a from Systemic Lupus Erythematosus Patients Regulates Senescence of Mesenchymal Stem Cells.

The senescence of mesenchymal stem cells (MSCs) plays a crucial role in the development and progression of systemic lupus erythematosus (SLE). Exosomes, small spherical bilayer proteolipid vesicles, contribute to the communication between various cells and their microenvironment by transferring information via their cargo, including the proteins, lipids, and RNAs. While exosomal miRNAs participate in various biological activities, correlations of circulating exosomes with senescent signs of BM-MSCs remain unclear. In our study, we aimed at exploring the roles of circulating exosomal miRNAs in
