Abstract
Screening bioactive compounds from natural sources, including animals and plants, is a valuable strategy for identifying novel anti-tumor agents. α-Toxin BmK-M9, a key component of scorpion venom, has received limited attention regarding its potential anti-cancer effects and underlying mechanisms in breast cancer. This study investigates the effects and mechanisms of BmK-M9 in breast cancer using in vitro experiments and a nude mouse model. mRNA sequencing was performed to identify affected signaling pathways, while Western blotting and immunohistochemistry were utilized to analyze the Wnt/β-catenin signaling pathway. The results demonstrated that BmK-M9 significantly inhibited breast cancer cell invasion and migration in vitro and suppressed tumor growth in vivo. Transcriptomic analysis revealed that BmK-M9 influenced cellular processes related to proliferation, apoptosis, motility, and metabolism. Furthermore, BmK-M9 markedly downregulated β-catenin expression in the Wnt/β-catenin pathway. These findings suggest that BmK-M9 exerts anti-tumor effects in breast cancer by modulating Wnt/β-catenin signaling, highlighting its potential as a promising therapeutic candidate.
期刊介绍:
Cell Biochemistry and Biophysics (CBB) aims to publish papers on the nature of the biochemical and biophysical mechanisms underlying the structure, control and function of cellular systems
The reports should be within the framework of modern biochemistry and chemistry, biophysics and cell physiology, physics and engineering, molecular and structural biology. The relationship between molecular structure and function under investigation is emphasized.
Examples of subject areas that CBB publishes are:
· biochemical and biophysical aspects of cell structure and function;
· interactions of cells and their molecular/macromolecular constituents;
· innovative developments in genetic and biomolecular engineering;
· computer-based analysis of tissues, cells, cell networks, organelles, and molecular/macromolecular assemblies;
· photometric, spectroscopic, microscopic, mechanical, and electrical methodologies/techniques in analytical cytology, cytometry and innovative instrument design
For articles that focus on computational aspects, authors should be clear about which docking and molecular dynamics algorithms or software packages are being used as well as details on the system parameterization, simulations conditions etc. In addition, docking calculations (virtual screening, QSAR, etc.) should be validated either by experimental studies or one or more reliable theoretical cross-validation methods.
