Опубликована: Сен. 26, 2024

Abstract Long non-coding RNAs (lncRNAs) have emerged as crucial regulators in various cellular processes, including cancer progression and stress response. Recent studies demonstrated that copper accumulation induces a unique form of cell death known cuproptosis, with lncRNAs playing key role regulating cuproptosis-associated pathways. These may trigger cell-specific responses to stress, presenting new opportunities prognostic markers therapeutic targets. This paper delves into the cuproptosis-mediated cancer, underscoring their potential biomarkers targets for innovative strategies. A thorough review scientific literature was conducted, utilizing databases such PubMed, Google Scholar, ScienceDirect, search terms like 'lncRNAs,' 'cuproptosis,' 'cancer.' Studies were selected based on relevance lncRNA regulation cuproptosis pathways implications prognosis treatment. The highlights significant contribution cuproptosis-related genes pathways, impacting metabolism, mitochondrial responses, apoptotic signaling. Specific are breast, lung, liver, ovarian, pancreatic, gastric cancers. objective this article is explore cancers mediated by cuproptosis.

Nanotherapy has emerged as a promising strategy for the targeted and efficient treatment of melanoma, most aggressive lethal form skin cancer, with minimized systemic toxicity. However, therapeutic efficacy cobalt oxide nanoparticles (Co3O4NPs) in melanoma remains unexplored. This study aimed to assess potential Co3O4NPs by evaluating their impact on cell viability, genomic DNA mitochondrial integrity, reactive oxygen species (ROS) generation apoptosis induction A-375 cells. Our findings demonstrated concentration-dependent reduction viability upon five Co3O4NP concentrations (0.2, 2, 20, 200, 2000 µg/ml), an IC50 value 303.80 µg/ml. Treatment this concentration significantly increased ROS generation, induced dramatic damage, disrupted membrane integrity. Flow cytometric analysis revealed necrosis following exposure at value. Results qRT-PCR remarkable dysregulation apoptotic genes, including significant downregulation p53 ND3 genes marked upregulation anti-apoptotic gene Bcl2. These highlight novel potent inducers death manner through excessive production, instability, dysfunction expression, ultimately promoting thus underscores nanotherapeutic candidate treatment, warranting further exploration elucidate full biological clinical applicability.

A prognostic model for lung adenocarcinoma based on cuproptosis and disulfidptosis related genes revealing the key prognostic role of FURIN

Scientific Reports, Год журнала: 2025, Номер 15(1)

Lung adenocarcinoma (LUAD) is the most common subtype of lung cancer. Despite advances in treatment, prognosis remains poor due to late diagnosis. Cuproptosis (driven by copper ion accumulation) and disulfidptosis disulfide bond are novel forms programmed cell death, closely linked tumor initiation, progression, resistance. However, specific roles these mechanisms LUAD remain inadequately studied. This study integrated multi-omics data from TCGA GEO databases systematically evaluate differential expression prognostic significance disulfide-related genes (DCRGs), identify two DCRG molecular subtypes, construct a scoring model based on four key genes. Multi-omics analysis results revealed that score not only accurately predicts patients but also associated with immune infiltration patterns EGFR inhibitor responses. RT-qPCR validated high FURIN RHOV cells, supporting their role as potential therapeutic targets. Further Mendelian randomization confirmed causal relationship between development. These findings provide biomarkers for evaluation cuproptosis offer theoretical basis targeting treatment.

Ecotoxicology is essential for the evaluation and comprehension of effects emergency pollutants (EP) such as heavy metal ions on natural environment. EPs pose a substantial threat to health humans proper functioning global ecosystem. The primary concern exposure animals through contaminated water. presence in drinking water ought be monitored accordance with World Health Organization regulations. Among numerous harmful ions, copper are responsible variety human diseases. This study investigates application phage display screening method toxicological targets, served main focus. To identify Cu-binding M13 clones unique peptides assess their affinity utilized Escherichia coli factories producing recombinant bacteriophages, modified biopanning procedure an ELISA assay. research highlights increasing importance tool ecotoxicology. We synthesized selected peptide enable rapid optical detection Cu(II) aqueous solutions. By incorporating dansyl group into designated sequence, we implemented fluorescence assays real-time measurements. Cu2+- binding peptide's efficacy was confirmed spectroscopic measurements, which allowed response times high selectivity. technique successfully applied develop fluorescent peptide-based chemosensor that exhibited selectivity sensitivity Cu2+.

Copper is an essential micronutrient involved in various physiological processes cell types. Consequently, dysregulation of copper homeostasis-either excessive or deficient-can lead to pathological changes, such as heart failure (HF). Recently, a new type copper-dependent death known cuproptosis has drawn increasing attention the impact dyshomeostasis on HF. Notably, was associated with occurrence Hence, this review aimed investigate biological uptake, transport, excretion, and storage at both cellular systemic levels terms HF, along underlying mechanisms action. Additionally, role its related mitochondrial dysfunction HF pathogenesis analyzed. Finally, we reviewed therapeutic potential current drugs that target metabolism for treating Overall, conclusions revealed copper-based therapies development strategies treatment
