WebDec 1, 2024 · Glutathione (GSH) has long been recognized as a valuable tumor biomarker [1]. Compared with normal tissues and cells, GSH levels are increased approximately 100-fold within tumor solids, and approximately 7–10 folds in cancer cells [2]. A high level of GSH is associated with rapid tumor proliferation, invasion, and drug resistance [3], [4]. Glutathione is an antioxidant in plants, animals, fungi, and some bacteria and archaea.
