ABSTRACT
PURPOSE: Gastric adenocarcinoma is a highly aggressive malignancy characterized by a complex tumor microenvironment. Nano-curcumin liposomes hold great potential in inhibiting tumor growth and survival, as well as inducing cuproptosis and oxidative stress. Although the anticancer properties of curcumin have been demonstrated, the specific mechanisms by which curcumin inhibites gastric adenocarcinoma through cuproptosis remains unclear. This study investigated how nano-curcumin liposomes mediated the inhibition of gastric adenocarcinoma cell proliferation and survival via cuproptosis.
METHODS: This study utilized the gastric adenocarcinoma cell line AGS to establish 2D and 3D in vitro gastric adenocarcinoma models. Furthermore, we prepared nano-curcumin liposomes to investigate their effects and regulatory mechanisms on AGS gastric adenocarcinoma models. A series of in vitro assays, including flow cytometry, CCK-8, scratch assays and morphological assessments, were performed to evaluate the effects of nano-curcumin liposomes on cell apoptosis, proliferation and migration. Additionally, bioinformatics and machine learning methods were employed to identify key targets that inhibited gastric adenocarcinoma growth and survival associated with nano-curcumin liposomes, which were further validated through RT-qPCR and omics analysis. Computer simulations were also conducted to assess the stability of binding interactions between curcumin and key target proteins.
RESULTS: Cellular experiments demonstrated that nano-curcumin liposomes significantly inhibited proliferation and invasive capacity of gastric adenocarcinoma cells while promoting cellular oxidative stress. Bioinformatics and machine learning analyses identified FDX1, GPX4, SERPINE1 and SLC27A5 as key targets. RT-qPCR results confirmed that nano-curcumin liposomes significantly downregulated the expression of these targets. Molecular dynamics simulations indicated that curcumin could form stable binding interactions with key protein targets.
CONCLUSION: This study revealed that nano-curcumin liposomes inhibited growth and survival of gastric adenocarcinoma cells by interfering with the expression of FDX1, GPX4, SERPINE1 and SLC27A5, which were closely linked to copper-induced oxidative stress. Nano-curcumin liposomes downregulated the expression of FDX1 and GPX4, disrupted mitochondrial energy metabolism, and induced oxidative stress, thereby promoting tumor-associated programmed cell death linked to cuproptosis. Furthermore, by downregulating SERPINE1, nano-curcumin liposomes modulated cell adhesion and migration, inhibiting the invasive and metastatic potential of tumor cells. Finally, downregulation of SLC27A5 altered tumor metabolism and cellular homeostasis, induced oxidative stress, and disrupted intracellular environmental stability, thereby suppressing the growth of gastric adenocarcinoma.

Harnessing multi-omics approaches to decipher tumor evolution and improve diagnosis and therapy in lung cancer
Biomark Res. 2025 Nov 5;13(1):140. doi: 10.1186/s40364-025-00859-y.
ABSTRACT
With the advancement of novel technologies such as whole-genome sequencing, single-cell sequencing, and spatial transcriptomics, single-omics analyses have already promoted the research of tumorigenesis as well as development and have partly elucidated the evolutionary processes of lung cancer. However, it is still difficult to distinguish these confounding features via single dimensional approaches due to the complexity, heterogeneity and cell-cell interactions with the immune microenvironment in lung cancer. Multi-omics approaches provide a holistic framework for constructing detailed tumor ecosystem landscapes, thereby facilitating the development of a more robust classification system for precision diagnosis and treatment, and aiding in the discovery of novel cancer biomarkers. In this review, we summarize the potential and applications of multi-omics approaches in characterizing intratumor heterogeneity and the tumor microenvironment throughout the course of lung cancer development. By further discussing the discovery and application of diagnostic and therapeutic biomarkers across precancerous lesions, early-stage lung cancer, tumor progression, metastasis, and therapy resistance, we outline the current challenges and future prospects of using multi-omics to identify reliable biomarkers. Moreover, we emphasize that integrative multi-omics models hold great promise for elucidating the complex interactions within the lung cancer ecosystem, thereby contributing to improved diagnostic accuracy, optimized therapeutic strategies, and better patient outcomes.

Improving dataset transparency in dermatologic Artificial Intelligence using a dataset nutrition label
npj Digital Medicine, Published online: 05 November 2025; doi:10.1038/s41746-025-02125-9
Biased and poorly documented dermatology datasets pose risks to the development of safe and generalizable artificial intelligence (AI) tools. We created a Dataset Nutrition Label (DNL) for multiple dermatology datasets to support transparent and responsible data use. The DNL offers a structured, digestible summary of key attributes, including metadata, limitations, and risks, enabling data users to better assess suitability and proactively address potential sources of bias in datasets.Evaluating clinical AI summaries with large language models as judges
