Background: This study aims to improve the solubility and the toxicity of Bufonis venenum, and finally enhance the therapeutic outcomes of hepatocellular carcinoma (HCC).

Methods: The cholesterol-free liposomes simultaneously encapsulate bufadienolides and indolealkylamines (Non-Cholesterol-Bufonis Venenum Extract-Liposome, Non-Chol-BVE-LP) was prepared by the thin-film evaporation technique. , the cytotoxicity, cell apoptosis study, cellular uptake and hemolysis studies were evaluated in HepG2 cells. , the biodistribution and anti-tumor activity studies were conducted in BALB/C mice with HepG2 cells.

Results: The liposomes showed good size distribution, encapsulation efficiency drug loading capacity and slower drug release. Non-Chol-BVE-LP had higher cytotoxicity on HepG2 cells and induced more apoptosis on HepG2 Cells compared with BVE. In addition, the liposomes could accumulate in tumor by passive targeting, thus facilitating the anti-tumor effects. , Non-Chol-BVE-LP showed equivalent anti-tumor efficacy to the first-line anti-HCC drug sorafenib.

Conclusion: The study provided new ideas for the development and clinical application of Bufonis venenum related formulation and offered new drug for the treatment of HCC.

Nuclear magnetic resonance (NMR) spectroscopy is a valuable diagnostic tool limited by low sensitivity due to low nuclear spin polarization. Hyperpolarization techniques, such as dissolution dynamic nuclear polarization, significantly enhance sensitivity, enabling real-time tracking of cellular metabolism. However, traditional high-field NMR systems and bioreactor platforms pose challenges, including the need for specialized equipment and fixed sample volumes.

To investigate the effect of icariin (ICA) on hepatocellular carcinoma (HCC) and its autophagy/apoptosis mechanism in HCC. The anti-HCC mechanism of ICA was investigated using HCC cells treated with 20 µmol/L ICA. Cell viability and proliferation were assessed using CCK-8 and colony formation assays, respectively, while TUNEL staining evaluated anti-apoptotic effects.

Over the last decade, research has emphasized the role of the microbiome in regulating cardiovascular physiology and disease progression. Understanding the interplay between wine polyphenols, the gut microbiota, and cardiovascular health could provide valuable insights for uncovering novel therapeutic strategies aimed at preventing and managing cardiovascular disease. In this study, two commercial red wines were subjected to dynamic gastrointestinal digestion (GIS) to monitor the flavanol-microbiota interaction by evaluating the resulting microbial metabolites.

Genotoxicity testing of the anthraquinone dye Alizarin Red S.

Curr Res Toxicol

December 2024

Institute of Nutrition and Food Science, Department of Food Safety, University of Bonn, Germany.

The anthraquinone dye Alizarin Red S (ARS) is used for marking live animals, specifically as a tool for monitoring the stock of the endangered European eel by marking caught fish with ARS before releasing the eels back into the wild. As ARS can be found in recaptured eels even years later, knowledge of potential health hazards of ARS is essential for assessing the food safety of eels marked with ARS. As the compound class of anthraquinones is known for their genotoxic and carcinogenic properties, concerns were raised regarding the food safety of marked eels.
