Context: Glutathione (GSH) is a major intracellular antioxidant capable of scavenging free radicals and detoxifying electrophiles from endogenous and exogenous sources via the free thiol group. GSH plays an important role in a multiple cellular process, including cell differentiation, proliferation, and apoptosis. Pharmacogenomics has demonstrated its important role as a key element in cellular health.
Objective: The study intended to examine the benefits of using GSH pharmacogenomics as a therapy to prevent side effects and interactions with antineoplastic agents in the diagnosis and treatment of malignancies.
Design: The research team performed a narrative review using the Google scholar and PubMed electronic databases.
Conclusions: In summary, the involvement of GSH in the carcinogenesis and drug resistance of tumor cells is clear and well understood, but further studies, aimed at understanding the GSH-driven molecular pathways, might be crucial to designing new therapeutic strategies to fight cancer progression, overcoming chemoresistance, using in combination with immunotherapies, and preventing or minimizing their negative side effects.
