Potential Novel Biomarkers in Chronic Graft-Versus-Host Disease.

Prognostic, diagnostic or predictive biomarkers are urgently needed for assessment of chronic graft-versus-host disease (cGvHD), a major risk for patients undergoing allogeneic hematopoietic stem cell transplantation. The main goal of this review generated within the COST Action EUROGRAFT "Integrated European Network on Chronic Graft Versus Host Disease" was to identify potential novel biomarkers for cGvHD besides the widely accepted molecular and cellular biomarkers. Thus, the focus was on cellular biomarkers, alloantibodies, glycomics, endothelial derived particles, extracellular vesicles, m

Advances in Gold Nanoparticle-Based Combined Cancer Therapy.

According to the global cancer observatory (GLOBOCAN), there are approximately 18 million new cancer cases per year worldwide. Cancer therapies are largely limited to surgery, radiotherapy, and chemotherapy. In radiotherapy and chemotherapy, the maximum tolerated dose is presently being used to treat cancer patients. The integrated development of innovative nanoparticle (NP) based approaches will be a key to address one of the main issues in both radiotherapy and chemotherapy: normal tissue toxicity. Among other inorganic NP systems, gold nanoparticle (GNP) based systems offer the means to fur

Моделирование и нацеливание враждебной физико-химической ниши в метастазе костей: от экспериментальных платформ до нишевой терапии.

Метастаз рака до костей формируется не только из-за перекрестка опухолей, но и из-за враждебной физико-химической ниши, которая способствует стойкости к болезням и терапевтической недостаточности. Гипоксия, кислотность, минерализированная матричная архитектура, изменённая механика, интерстициальное давление, дисфункция перфузии и ограниченный перенос наркотиков влияют на метастатическое семя, общность, реактивацию, реконструкцию, боль и реакцию на лечение. Обычные two- размерные культуры и многие упрощенные three- размерные системы воспроизводят только отдельные особенности этой среды, часто п

Epigenetics-targeted drugs: current paradigms and future challenges.

Epigenetics governs a chromatin state regulatory system through five key mechanisms: DNA modification, histone modification, RNA modification, chromatin remodeling, and non-coding RNA regulation. These mechanisms and their associated enzymes convey genetic information independently of DNA base sequences, playing essential roles in organismal development and homeostasis. Conversely, disruptions in epigenetic landscapes critically influence the pathogenesis of various human diseases. This understanding has laid a robust theoretical groundwork for developing drugs that target epigenetics-modifyin

JunB is a key regulator of multiple myeloma bone marrow angiogenesis.

Bone marrow (BM) angiogenesis significantly influences disease progression in multiple myeloma (MM) patients and correlates with adverse prognosis. The present study shows a statistically significant correlation of the AP-1 family member JunB with VEGF, VEGFB, and IGF1 expression levels in MM. In contrast to the angiogenic master regulator Hif-1α, JunB protein levels were independent of hypoxia. Results in tumor-cell models that allow the induction of JunB knockdown or JunB activation, respectively, corroborated the functional role of JunB in the production and secretion of these angiogenic fa

Cytokine-Engineered Chimeric Antigen Receptor-T Cell Therapy: How to Balance the Efficacy and Toxicity.

Chimeric antigen receptor (CAR)-T cell immunotherapy has revolutionized the paradigm in hematological malignancies. However, its efficacy in treating solid tumors remains limited because the immunosuppressive tumor microenvironment (ITME) seriously blocks T cell activation, infiltration, and proliferation. Cytokines, driving potent assisted function by enhanced T cell expansion, persistence, and direct tumor cell killing, have long been acknowledged as promising candidates combined with CAR-T cells to improve treatment outcomes. Despite their preclinical success, significant toxicity occurs in

What is the Reason That the Pharmacological Future of Chemotherapeutics in the Treatment of Lung Cancer Could Be Most Closely Related to Nanostructures? Platinum Drugs in Therapy of Non-Small and Small Cell Lung Cancer and Their Unexpected, Possible Interactions. The Review.

Over the course of several decades, anticancer treatment with chemotherapy drugs for lung cancer has not changed significantly. Unfortunately, this treatment prolongs the patient's life only by a few months, causing many side effects in the human body. It has also been proven that drugs such as Cisplatin, Carboplatin, Oxaliplatin and others can react with other substances containing an aromatic ring in which the nitrogen atom has a free electron group in its structure. Thus, such structures may have a competitive effect on the nucleobases of DNA. Therefore, scientists are looking not only for

Molecular mechanisms underlying methotrexate-induced intestinal injury and protective strategies.

Methotrexate (MTX) is a folic acid reductase inhibitor that manages various malignancies as well as immune-mediated inflammatory chronic diseases. Despite being frequently prescribed, MTX's severe multiple toxicities can occasionally limit its therapeutic potential. Intestinal toxicity is a severe adverse effect associated with the administration of MTX, and patients are significantly burdened by MTX-provoked intestinal mucositis. However, the mechanism of such intestinal toxicity is not entirely understood, mechanistic studies demonstrated oxidative stress and inflammatory reactions as key fa

Influence of the Mediterranean Diet on Healthy Aging.

The life expectancy of the global population has increased. Aging is a natural physiological process that poses major challenges in an increasingly long-lived and frail population. Several molecular mechanisms are involved in aging. Likewise, the gut microbiota, which is influenced by environmental factors such as diet, plays a crucial role in the modulation of these mechanisms. The Mediterranean diet, as well as the components present in it, offer some proof of this. Achieving healthy aging should be focused on the promotion of healthy lifestyle habits that reduce the development of pathologi

Cardiotoxicity Induced by Anticancer Therapies: A Call for Integrated Cardio-Oncology Practice.

The introduction of novel oncologic therapies, including targeted agents, immunotherapies, and antibody-drug conjugates, has transformed the therapeutic landscape of cancer care. This evolution has resulted in a dual clinical scenario; while survival outcomes have markedly improved, leading to a growing population of long-term cancer survivors, an increasing incidence of previously unrecognized treatment-related toxicities has emerged. Among these, cardiovascular adverse events represent some of the most prevalent and clinically significant complications observed in both conventional chemother

CAR T cells: engineered immune cells to treat brain cancers and beyond.

Malignant brain tumors rank among the most challenging type of malignancies to manage. The current treatment protocol commonly entails surgery followed by radiotherapy and/or chemotherapy, however, the median patient survival rate is poor. Recent developments in immunotherapy for a variety of tumor types spark optimism that immunological strategies may help patients with brain cancer. Chimeric antigen receptor (CAR) T cells exploit the tumor-targeting specificity of antibodies or receptor ligands to direct the cytolytic capacity of T cells. Several molecules have been discovered as potential t

Phytochemicals as Chemo-Preventive Agents and Signaling Molecule Modulators: Current Role in Cancer Therapeutics and Inflammation.

Cancer is one of the deadliest non communicable diseases. Numerous anticancer medications have been developed to target the molecular pathways driving cancer. However, there has been no discernible increase in the overall survival rate in cancer patients. Therefore, innovative chemo-preventive techniques and agents are required to supplement standard cancer treatments and boost their efficacy. Fruits and vegetables should be tapped into as a source of compounds that can serve as cancer therapy. Phytochemicals play an important role as sources of new medication in cancer treatment. Some synthet

How the mechanical microenvironment of stem cell growth affects their differentiation: a review.

Stem cell differentiation is of great interest in medical research; however, specifically and effectively regulating stem cell differentiation is still a challenge. In addition to chemical factors, physical signals are an important component of the stem cell ecotone. The mechanical microenvironment of stem cells has a huge role in stem cell differentiation. Herein, we describe the knowledge accumulated to date on the mechanical environment in which stem cells exist, which consists of various factors, including the extracellular matrix and topology, substrate stiffness, shear stress, hydrostati

Hijacking the helpers: platelet and neutrophil trafficking in AML and therapeutic exploitation.

Acute myeloid leukemia (AML) remains one of the most aggressive and treatment-resistant hematologic malignancies, driven by clonal expansion of immature myeloid blasts in the bone marrow and peripheral blood. Current therapies-chemotherapy and targeted agents-are limited by poor marrow penetration, systemic toxicity, and rapid development of resistant clones, leaving long-term survival rates low. Clinicians face the persistent challenge of delivering effective therapy while minimizing harm. Platelets and neutrophils-beyond their classical roles in hemostasis and innate immunity-actively suppor

Acute kidney injury: pathogenesis and therapeutic interventions.

Acute kidney injury (AKI) is a prevalent clinical condition that is associated with unacceptably high morbidity and mortality, as well as the development of chronic kidney disease (CKD). The pathogenesis of AKI is highly complex and heterogeneous, primarily attributed to metabolic disturbances arising from the disease itself and the administration of medications related to treatment. In recent years, AKI in cancer patients is highly concerned. The emergence of AKI caused injuries and dysfunction of remote organs but also enhanced the health-care costs. It's essential for early recognition of A
