Monoclonal Antibodies-Anchored Quantum Dots-Based Delivery Strategies for Glioblastoma Treatment: Challenges and Applications.

Treatment of glioblastoma multiforme (GBM) has been a great challenge before medical fraternity since last century owing to a median survival of less than 15 months, despite of intensive therapy. Neurosurgeries, intense chemotherapy, advanced radiotherapy, and targeted therapies have bought some extension to the life of GBM patients. Combination and targeted therapies could bring a concrete approach to tackle the complexities of GBM treatment. Monoclonal antibodies (mAbs) have already proved their potential, owing to their high affinity and target-specificity, as a promising cancer immunothera

Modulation of Angiogenic Processes by the Human Gammaherpesviruses, Epstein-Barr Virus and Kaposi's Sarcoma-Associated Herpesvirus.

Angiogenesis is the biological process by which new blood vessels are formed from pre-existing vessels. It is considered one of the classic hallmarks of cancer, as pathological angiogenesis provides oxygen and essential nutrients to growing tumors. Two of the seven known human oncoviruses, Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV), belong to the Gammaherpesvirinae subfamily. Both viruses are associated with several malignancies including lymphomas, nasopharyngeal carcinomas, and Kaposi's sarcoma. The viral genomes code for a plethora of viral factors, includin

Thirty years from FDA approval of pegylated liposomal doxorubicin (Doxil/Caelyx): an updated analysis and future perspective.

In 2025, it will be 30 years since the initial clinical approval of pegylated liposomal doxorubicin (PLD) by the Food and Drug Administration. PLD predated the field of nanomedicine and became a model nanomedicine setting key pharmacological principles (prolonged circulation, slow drug release and the enhanced permeability and retention (EPR) effect) for clinical application of other nano-drugs in cancer therapy. The impressive reduction of cardiotoxicity conferred by PLD is the most valuable clinical asset. While PLD has gained a strong foothold in relapsed ovarian cancer and metastatic breas

Cardiac safety analysis of first-line chemotherapy drug pegylated liposomal doxorubicin in ovarian cancer.

Pegylated liposomal doxorubicin (PLD) is a nano-doxorubicin anticancer agent. It was used as early as 2014 to treat ovarian and breast cancer, multiple myeloma and Kaposi's sarcoma. The 2018 National Comprehensive Cancer Network guidelines listed PLD as first-line chemotherapy for ovarian cancer. PLD has significant anticancer efficacy and good tolerance. Although PLD significantly reduces the cardiotoxicity of conventional doxorubicin, its cumulative-dose cardiotoxicity remains a clinical concern. This study summarizes the high-risk factors for PLD-induced cardiotoxicity, clinical dose thresh

Evaluation of Proteasome Inhibitors in the Treatment of Idiopathic Pulmonary Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is the most common form of idiopathic interstitial pneumonia, and it has a worse prognosis than non-small cell lung cancer. The pathomechanism of IPF is not fully understood, but it has been suggested that repeated microinjuries of epithelial cells induce a wound healing response, during which fibroblasts differentiate into myofibroblasts. These activated myofibroblasts express α smooth muscle actin and release extracellular matrix to promote matrix deposition and tissue remodeling. Under physiological conditions, the remodeling process stops once wound heal

Targeting vascular endothelial growth receptor-2 (VEGFR-2): structural biology, functional insights, and therapeutic resistance.

Angiogenesis, the process of new blood vessel formation, is a fundamental physiological process implicated in several pathological disorders. The vascular endothelial growth factors (VEGFs) and their receptors (VEGFRs) are crucial for angiogenesis and vasculogenesis. Among them, the tyrosine kinase receptor VEGFR-2 is primarily expressed in endothelial cells (ECs). These cells regulate various physiological responses, including differentiation, cell proliferation, migration, and survival, by binding to VEGF mitogens. Vascular Endothelial Growth Factor Receptor 2 (VEGFR-2) is a key regulator of

Cytokine release syndrome in solid tumours: mechanism-based therapeutic strategies for prevention and management.

Cytokine release syndrome (CRS) represents a spectrum of immune hyperactivation initiated by rapid T-cell engagement and amplified through innate immune cells, particularly monocytes and macrophages, with downstream cytokine cascades driving endothelial dysfunction, capillary leak and organ impairment. CRS is a frequent, class-associated toxicity of T-cell-engaging immunotherapies and is being observed with increasing regularity as T-cell-redirecting therapies progress through clinical development in solid tumours. Although CRS is typically less severe in patients with solid tumours relative t

Epigenetic Dysregulation in Neurodegeneration: The Role of Histone Deacetylases and Emerging Inhibitor Strategies.

Neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD) are characterized by complex pathologies with progressive neurodegeneration, protein misfolding, oxidative stress, and persistent inflammation. Recent findings indicate the pivotal involvement of epigenetic disruption, particularly aberrant histone deacetylase (HDAC) activity, in disease initiation and progression. In the current review, we systematically discuss the mechanistic function of HDACs across all classes (I, IIa, IIb, III, and IV) in neurodegenerative disease mechanis

Изучение ацетилхолинового разнообразия рецептора в нематодном паразите приводит к характеристике чувствительных к племени и дерквантель NAChR.

Никотинические ацетилхолинные рецепторы (NAChRs) паразитических нематод, необходимые для движения тела, являются объектами важных "классических" антеллиментов, таких как левамизол и пирантель, а также "новых" антеллиментов, таких как племянник и дерквантель.

Diffusion MRI for Assessment of Bone Quality; A Review of Findings in Healthy Aging and Osteoporosis.

Diffusion MRI (dMRI) is a growing imaging technique with the potential to provide biomarkers of tissue variation, such as cellular density, tissue anisotropy, and microvascular perfusion. However, the role of dMRI in characterizing different aspects of bone quality, especially in aging and osteoporosis, has not yet been fully established, particularly in clinical applications. The reason lies in the complications accompanied with implementation of dMRI in assessment of human bone structure, in terms of acquisition and quantification. Bone is a composite tissue comprising different elements, ea

Metronomic Anti-Cancer Therapy: A Multimodal Therapy Governed by the Tumor Microenvironment.

The concept of cancer as a systemic disease, and the therapeutic implications of this, has gained special relevance. This concept encompasses the interactions between tumor and stromal cells and their microenvironment in the complex setting of primary tumors and metastases. These factors determine cellular co-evolution in time and space, contribute to tumor progression, and could counteract therapeutic effects. Additionally, cancer therapies can induce cellular and molecular responses in the tumor and host that allow them to escape therapy and promote tumor progression. In this study, we descr

Platinum-induced ototoxicity and hearing impairment in children and adolescents.

Platinum compounds play a crucial role in the treatment of solid tumours in paediatric patients, significantly improving survival rates. However, these treatments can result in hearing loss as a side-effect that can significantly impact the quality of life of young cancer survivors. Whilst the therapeutic benefits of platinum compounds in paediatric oncology are indisputable, addressing the challenge of ototoxicity remains a priority. Early and regular auditory function assessments, with tools such as audiometry, otoacoustic emissions and auditory brainstem response testing, are critical durin

Functional magnetic resonance imaging in oncology: state of the art.

In the investigation of tumors with conventional magnetic resonance imaging, both quantitative characteristics, such as size, edema, necrosis, and presence of metastases, and qualitative characteristics, such as contrast enhancement degree, are taken into consideration. However, changes in cell metabolism and tissue physiology which precede morphological changes cannot be detected by the conventional technique. The development of new magnetic resonance imaging techniques has enabled the functional assessment of the structures in order to obtain information on the different physiological proces

Cannabidiol on the Path from the Lab to the Cancer Patient: Opportunities and Challenges.

Cannabidiol (CBD), a major non-psychotropic component of cannabis, is receiving growing attention as a potential anticancer agent. CBD suppresses the development of cancer in both in vitro (cancer cell culture) and in vivo (xenografts in immunodeficient mice) models. For critical evaluation of the advances of CBD on its path from laboratory research to practical application, in this review, we wish to call the attention of scientists and clinicians to the following issues: (a) the biological effects of CBD in cancer and healthy cells; (b) the anticancer effects of CBD in animal models and clin

Mechanisms and management of CAR T toxicity.

Chimeric antigen receptor (CAR) T cell therapies have dramatically improved treatment outcomes for patients with relapsed or refractory B-cell acute lymphoblastic leukemia, large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, and multiple myeloma. Despite unprecedented efficacy, treatment with CAR T cell therapies can cause a multitude of adverse effects which require monitoring and management at specialized centers and contribute to morbidity and non-relapse mortality. Such toxicities include cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome, neuro

Specific epigenetic regulators serve as potential therapeutic targets in idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF), a disorder observed mostly in older human beings, is characterised by chronic and progressive lung scarring leading to an irreversible decline in lung function. This health condition has a dismal prognosis and the currently available drugs only delay but fail to reverse the progression of lung damage. Consequently, it becomes imperative to discover improved therapeutic compounds and their cellular targets to cure IPF. In this regard, a number of recent studies have targeted the epigenetic regulation by histone deacetylases (HDACs) to develop and categorise

Cardiovascular Toxicities with Chimeric Antigen Receptor T-cell Therapy.

Chimeric antigen receptor (CAR) T-cell therapy has shown remarkable efficacy in treating highly refractory and relapsing hematological malignancies in pediatric and adult patients. However, this promising therapy is limited by severe and potentially life-threatening toxicities. Cytokine release syndrome (CRS) is the most commonly observed of these toxicities. The cardiovascular manifestations of CRS include tachycardia, hypotension, left ventricular dysfunction, arrhythmias, troponin elevation, cardiogenic shock, and pulmonary edema. Recent data suggest that cardiotoxicities may be transient a
