The study aimed to demonstrate that matrine can reduce apoptosis in H9c2 cells induced by the cardiotoxic anticancer drug doxorubicin (DOX).The researchers pretreated H9c2 cells with different concentrations of matrine before exposing them to DOX and cultured them for 24 h. They assessed cell survival rates using cell counting kit-8 and MTT assay. Hoechst 33258 dye kits were used to determine apoptosis, while laser confocal JC-1 method was applied to test the mitochondrial membrane potential (MMP). Complex I activities were detected following the manufacturer's protocol. The results indicated that matrine pretreatment significantly increased the survival rate of H9c2 cells injured by DOX. Additionally, matrine reduced apoptosis in H9c2 cells through the improvement of MMP and activity of Complex I, which were damaged by DOX.

Background: Maslinic acid (MA), a pentacyclic triterpenoid compound derived from leaves and fruits of Olea europaea, bears multi-pharmacological properties. Our previous studies found that MA exerted a cardioprotective effect by modulating oxidative stress, inflammation, and apoptosis during myocardial ischemia-reperfusion injury (MIRI). Nevertheless, data regarding the anti-ferroptosis effects of MA on MI/RI remains unidentified.

G protein-coupled receptor 40 (GPR40) is gaining recognition as a potential therapeutic target for several metabolic disturbances, such as hyperglycemia and excessive inflammation. GPR40 is expressed in various tissues, including the heart; however, its specific roles in cardiomyocytes remain unknown. The objective of the present study was to investigate whether treatment with AM1638, a GPR40-full agonist, reduces palmitate-mediated cell damage in H9c2 rat cardiomyocytes.

Objectives: To deeply explore the mechanism of pachymic acid (PA) intervention in myocardial ischemia, providing new ideas and methods for the treatment of myocardial ischemia.
Methods: Predict the targets of PA for improving myocardial ischemia, and conduct functional enrichment analysis using databases, such as Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and Reactome. To verify these findings, PPI network topology analysis and molecular docking were used to screen key targets and main mechanisms of action and further validated through in vitro experiments on the H9C2 cell line.

Background: Myocardial ischemia/reperfusion (I/R) injury is a common pathophysiological change after myocardial reperfusion therapy. Recent research confirmed that long non-coding RNA (IncRNAs) played an important role in many cardiovascular diseases. This study was carried out to explore the role of lncRNA XR008038 in the I/R progression.

Electrochemical impedance spectroscopy (EIS) serves as a non-invasive technique for assessing cell status, while mechanical stretching plays a pivotal role in stimulating cells to emulate their natural environment. Integrating these two domains enables the concurrent application of mechanical stimulation and EIS in a stretchable cell culture system. However, challenges arise from the difficulty in creating a durable and stable stretchable impedance electrode array.
