Cuproptosis, a recently discovered form of regulated cell death involving copper ion metabolism, has emerged as a promising approach for tumor therapy. This pathway not only directly eliminates tumor cells but also promotes immunogenic cell death (ICD), reshaping the tumor microenvironment (TME) and initiating robust anti-tumor immune responses. However, translating cuproptosis-based therapies into clinical applications is hindered by challenges, including complex metabolic regulation, TME heterogeneity, and the precision required for effective drug delivery. To address these limitations, nanoparticles offer transformative solutions by providing precise delivery of cuproptosis-inducing agents, controlled drug release, and enhanced therapeutic efficacy through simultaneous modulation of metabolic pathways and immune responses. This review systematically discusses recent advancements in nanoparticle-based cuproptosis delivery systems, highlighting nanoparticle design principles and their synergistic effects when integrated with other therapeutic modalities such as ICB, PTT, and CDT. Furthermore, we explore the potential of cuproptosis-based nanomedicine for personalized cancer treatment by emphasizing strategies for TME stratification and therapeutic optimization tailored to patient profiles. By integrating current insights from metabolic reprogramming, tumor immunotherapy, and nanotechnology, this review aims to facilitate the clinical translation of cuproptosis nanomedicine and significantly contribute to the advancement of precision oncology.

Cholesterol,as an important component of cell membranes,plays a multifaceted role in mediating tumor immunomodulation and drug intervention.In case of cholesterol metabolic imbalance,the accumulation of cholesterol metabolic intermediates,the changes in concentrations,and the regulation of related signaling pathways can affect tumor immunity by promoting inflammation and inhibiting immune cell function.Preclinical and clinical studies have shown that controlling cholesterol metabolism can inhibit tumor growth,re-shape body immune regulation,and enhance antitumor immunity.A deep understanding of the association between immune cells and cholesterol metabolic pathways in the tumor microenvironment can help to develop novel drugs targeting cholesterol metabolism.This article reviews the multifaceted role of cholesterol and its derived metabolites in the tumor microenvironment by regulating various types of immune cells such as myeloid-derived suppressor cells,tumor-associated macrophages,dendritic cells,and T-lymphocytes,as well as the characteristics of tumor immunomodulation mediated by cholesterol metabolism and the advances in pharmaceutical re-search on improving the immune function of the body by intervening against cholesterol,in order to further provide new ideas and a thera-peutic basis for cholesterol modulation and intervention in tumor im-munotherapy.

Objective:To investigate the serum levels of miR-19b and miR-744-5p in patients with non-small cell lung cancer (NSCLC), and to analyze the clinical value of miR-19b and miR-744-5p in the diagnosis of NSCLC.Methods:A total of 226 NSCLC patients (NSCLC group) and 100 healthy people (control group) admitted to Jilin Cancer Hospital from August 2019 to August 2022 were selected as research objects. Quantitative real-time PCR was used to measure and compare the serum levels of miR-19b and miR-744-5p between the NSCLC group and the control group, and the relationships between the two indicators and different clinical and pathological characteristics of NSCLC patients were analyzed. The receiver operating characteristic curve was used to analyze the clinical value of miR-19b, miR-744-5p and their joint detection in the diagnosis of NSCLC.Results:Compared with the control group, the serum miR-19b level (3.86±1.25 vs. 1.06±0.41) in the NSCLC group significantly increased ( t=21.87, P<0.001), while the miR-744-5p level (1.80±0.48 vs. 5.75±1.69) significantly decreased ( t=32.36, P<0.001). The serum miR-19b levels in NSCLC patients with pathological types of adenocarcinoma, maximum tumor diameter ≥3 cm, medium to low differentiation, stage Ⅲ-Ⅳ, and with lymph node metastasis were higher than those in squamous cell carcinoma ( t=5.94, P<0.001), maximum tumor diameter <3 cm ( t=2.65, P=0.009), well differentiation ( t=4.33, P<0.001), stageⅠ-Ⅱ ( t=12.32, P<0.001), patients without lymph node metastasis ( t=8.13, P<0.001), while miR-744-5p levels were lower than those in squamous cell carcinoma ( t=8.27, P<0.001), tumor maximum diameter <3 cm ( t=5.34, P<0.001), well differentiation ( t=6.95, P<0.001), stageⅠ-Ⅱ ( t=11.40, P<0.001), patients without lymph node metastasis ( t=10.36, P<0.001). The area under the curve (AUC) of serum miR-19b combined with miR-744-5p in the diagnosis of NSCLC was 0.914 (95% CI: 0.841-0.959), with sensitivity and specificity of 90.9% and 84.0%, respectively. AUC was significantly than that of the single indicator detection of miR-19b (AUC=0.824, 95% CI: 0.770-0.869) and miR-744-5p (AUC=0.783, 95% CI: 0.709-0.838) ( Z=2.28, P=0.021; Z=2.36, P=0.017) . Conclusion:Serum miR-19b level of NSCLC patients is increased, miR-744-5p levels is decreased, and joint detection of serum miR-19b and miR-744-5p has high clinical value in the diagnosis of NSCLC.
