Hong-Bai-Lan-Shen Extract Alleviates the CoCl2-Induced Apoptosis in H9C2 Cells by Regulating the AMPK Pathway

Year: 2025

Type: article

Abstract: This study aims to explore the protective effects of Hong-bai-lan-shen (HBLS) extract, a traditional Chinese medicine compound, on myocardial injury based on metabolomics. H9C2 cells were cultured with HBLS extract for 12 h, and then the cells were cultured in a CoCl2-containing medium, a model simulating the ischemic-hypoxic damage in myocardial cells, for an additional 12 h. The cell viability, cytotoxicity, intracellular metabolite and reactive oxygen species (ROS), mitochondrial membrane potential, apoptosis, and adenosine monophosphate-activated protein kinase (AMPK) signal pathway were determined. The results showed that HBLS extract significantly increased cell viability, stabilized cell morphology, reduced lactate dehydrogenase (LDH) release and ROS production, blocked cysteine-aspartic acid protease 3 (caspase-3) and bcl-2-associated X protein (Bax) expression and decreased apoptotic cell numbers. Meanwhile, HBLS increased membrane potential and the expression of B-cell lymphoma-2 (Bcl-2). Additionally, HBLS extract upregulated the expression of AMPK, PI3K, and protein kinase B (AKT) (p < 0.05, p < 0.01). These findings suggest that HBLS extract has a protective effect on myocardial cells by regulating the AMPK signal pathway and may be a promising therapeutic candidate for ischemic heart disease.
