Iron deprivation in cancer--potential therapeutic implications.

Iron is essential for normal cellular function. It participates in a wide variety of cellular processes, including cellular respiration, DNA synthesis, and macromolecule biosynthesis. Iron is required for cell growth and proliferation, and changes in intracellular iron availability can have significant effects on cell cycle regulation, cellular metabolism, and cell division. Perhaps not surprisingly then, neoplastic cells have been found to have higher iron requirements than normal, non-malignant cells. Iron depletion through chelation has been explored as a possible therapeutic intervention i

Processes and therapeutic perspectives of acylation modifications of lysine and cysteine in tumors.

Acylation modification plays a crucial role in tumor progression through altering protein homeostasis and localization. However, a comprehensive summary of these processes is lacking. Protein acylation modifications are comprehensively summarized and categorized based on the amino acids that are modified. This review focuses on modifications of the lysine (acetylation, succinylation, crotonylation, malonylation, and glutarylation) and cysteine (myristoylation and palmitoylation) groups. The key enzymes involved in the occurrence and erasure of different modifications, as well as their effects

Ferroptosis in Haematological Malignancies and Associated Therapeutic Nanotechnologies.

Haematological malignancies are heterogeneous groups of cancers of the bone marrow, blood or lymph nodes, and while therapeutic advances have greatly improved the lifespan and quality of life of those afflicted, many of these cancers remain incurable. The iron-dependent, lipid oxidation-mediated form of cell death, ferroptosis, has emerged as a promising pathway to induce cancer cell death, particularly in those malignancies that are resistant to traditional apoptosis-inducing therapies. Although promising findings have been published in several solid and haematological malignancies, the major

Targeting the NLRP3 inflammasome in kidney disease: molecular mechanisms, pathogenic roles, and emerging small-molecule therapeutics.

Inflammatory responses represent a core pathological process driving the progression of both acute and chronic kidney diseases. As a key effector of the innate immune system, the NLRP3 inflammasome is widely activated in renal resident cellsand infiltrating immune cells, positioning it as a critical nexus linking metabolic dysregulation, cellular stress, and tissue injury. Accumulating preclinical and clinical evidence in recent years demonstrates that aberrant activation of the NLRP3 inflammasome directly promotes glomerular damage, tubulointerstitial inflammation, fibrosis, and vascular dysf

ADMET-Guided Design and In Silico Planning of Boron Delivery Systems for BNCT: From Transport and Biodistribution to PBPK-Informed Irradiation Windows.

BNCT (Boron Neutron Capture Therapy) is a binary radiotherapeutic modality in which high LET (Linear Energy Transfer) particles are generated from 10B(n,α)7Li reaction, ideally within boron-loaded tumour cells, so the therapeutic outcome depends critically on the pharmacokinetics and biodistribution of boron carriers. In this review, boron-containing agents for BNCT, with a focus on ADMET (absorption, distribution, metabolism, excretion and toxicity) and model-informed design, were examined. Low-MW (low-molecular-weight) compounds, peptide conjugates, polymeric and nanostructured platforms and

Иммуномодулирующий и противовоспалительный потенциал S-нитросглутатиона (GSNO) при множественной склерозе: обзор механизмов и терапевтических перспектив.

Многофакторная демиелинизация (МС) — это хроническое аутоиммунное заболевание центральной нервной системы (СНС), характеризующееся длительной нейроинфляминацией, окислительным стрессом, демиелинизацией и прогрессирующей нейродегенерацией. Несмотря на то, что МС остается неизлечимым, современные терапевтические средства (ТМС) помогают снизить частоту обострений и задерживать прогрессирование заболевания. Недавно разработанные инъекционные и инфузийные биологические ТМС обеспечивают целенаправленную иммуномодуляцию, но их клиническая полезность ограничена родственными методами введения и возможн

Rethinking the Combination of Proton Exchanger Inhibitors in Cancer Therapy.

Microenvironmental acidity is becoming a key target for the new age of cancer treatment. In fact, while cancer is characterized by genetic heterogeneity, extracellular acidity is a common phenotype of almost all cancers. To survive and proliferate under acidic conditions, tumor cells up-regulate proton exchangers and transporters (mainly V-ATPase, Na⁺/H⁺ exchanger (NHE), monocarboxylate transporters (MCTs), and carbonic anhydrases (CAs)), that actively extrude excess protons, avoiding intracellular accumulation of toxic molecules, thus becoming a sort of survival option with many similarities

The role of heat shock protein 90 in idiopathic pulmonary fibrosis: state of the art.

Heat shock protein 90 (HSP 90) and its isoforms are a group of homodimeric proteins that regulate several cellular processes, such as the elimination of misfolded proteins, cell development and post-translational modifications of kinase proteins and receptors. Due to its involvement in extracellular matrix (ECM) remodelling, myofibroblast differentiation and apoptosis, HSP 90 has been investigated as a key player in the pathogenesis of lung fibrosis. Idiopathic pulmonary fibrosis (IPF) is the most common and deadly interstitial lung disease, due to the progressive distortion of lung parenchyma

Systemic Therapies for Desmoid Tumors: A Review of Past, Present, and Future Treatments.

Desmoid tumors (DTs) are rare, fibroblastic neoplasms characterized by locally aggressive behavior, unpredictable clinical trajectories, and a substantial impact on patient quality of life despite minimal metastatic potential. Although the underlying biology of DTs remains incompletely defined, associations with prior trauma, hormonal exposure, and aberrant Wnt/β-catenin signaling-including somatic CTNNB1 mutations and germline APC alterations seen in Familial Adenomatous Polyposis-have informed both historical and contemporary therapeutic approaches. Management strategies have evolved from su

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

Covalent targeting of PSMD14 by Eupalinolide B induces oncoprotein degradation and apoptosis in acute promyelocytic leukemia cells.

Treatment of acute promyelocytic leukemia (APL) remains challenged by toxicities associated with current regimens, highlighting the need for novel and safer therapeutic agents. Here, we identify Eupalinolide B (EB), a natural sesquiterpene lactone isolated from Eupatorium lindleyanum DC., as a potent anti-leukemic compound targeting the human APL-derived HL-60 cell line. Through integrated chemoproteomic profiling and functional validation, we demonstrate that EB covalently binds and inhibits 26S proteasome non-ATPase regulatory subunit 14 (PSMD14), a deubiquitinase enzyme (DUB) within the 19S
