Abstract

Laryngeal squamous cell carcinoma is a common type of head and neck cancer. This study investigated the role of the TRPM2 channel in doxorubicin (DOX)-induced cell damage in human laryngeal squamous cancer cells (Hep-2). Cells were exposed to various DOX concentrations and the appropriate dose was found. Then, TRPM2 antagonist ACA was treated. At the end of the study, cell viability test, Western blot and oxidative stress and inflammatory markers were examined. The results showed that TRPM2 channel expression increased with DOX administration, and DOX incubation in cells caused an increase in ROS, MDA, IL-1β, IL-6, and TNF-α levels, while GSH and GSH-Px levels decreased. Concurrent treatment with ACA attenuated these effects and reduced oxidative stress and inflammation. In addition, DOX-induced apoptosis markers including Casp-3, Casp-8, Casp-9, p53, and Bax were elevated, while Bcl-2 levels were decreased; ACA treatment reversed these changes. The study demonstrated that DOX treatment significantly enhances TRPM2 channel activation and ROS production in Hep-2 cells, thereby initiating apoptotic pathways that lead to cell death. Consequently, targeting the TRPM2 channel may represent a promising therapeutic strategy for treating laryngeal cancer.

期刊介绍: Doklady Biochemistry and Biophysics is a journal consisting of English translations of articles published in Russian in biochemistry and biophysics sections of the Russian-language journal Doklady Akademii Nauk. The journal''s goal is to publish the most significant new research in biochemistry and biophysics carried out in Russia today or in collaboration with Russian authors. The journal accepts only articles in the Russian language that are submitted or recommended by acting Russian or foreign members of the Russian Academy of Sciences. The journal does not accept direct submissions in English.
