Description
Summary:Diallyl trisulfide (DATS), an organosulfide compound derived from garlic, is renowned for its potent antioxidant properties, particularly in countering the generation of reactive oxygen species (ROS). It has also gained recognition as a potential agent for preventing heart-related conditions. Doxorubicin (Dox), a commonly used chemotherapeutic drug, is known to induce severe cardiac complications by promoting ROS production. Therefore, it was imperative to investigate whether DATS possesses cardioprotective capabilities against Dox-induced cardiac apoptosis and elucidate the underlying mechanisms. In this study, we observed that the intracellular ROS levels and cardiac apoptosis were heightened in H9c2 cells exposed to Dox (1 μM). However, treatment with 10 μM DATS effectively mitigated the Dox-induced ROS generation and apoptotic signaling, concurrently activating the PI3K/Akt pathway. Notably, the anti-apoptotic effects of DATS were attenuated when PI3K siRNA and the LY294002 PI3K inhibitor were employed. Furthermore, the TUNEL assay results demonstrated a significant reduction in Dox-induced apoptosis with DATS treatment. In summary, our findings indicate that DATS can activate the PI3K/Akt pathway, reducing ROS production in cardiac cells exposed to Dox, and subsequently rescue cardiac cells from apoptosis.
