The presence of fibroblasts, which can harbor high endogenous levels of glutathione and cysteine, has been shown to increase ovarian cancer cell resistance.

In summary, glutathione plays a pivotal and often contradictory role in ovarian cancer. While offering potential benefits in mitigating chemotherapy-induced toxicity and improving the quality of life for patients, its involvement in promoting chemoresistance and influencing disease progression cannot be ignored. Ongoing research continues to unravel these intricate mechanisms, identifying specific glutathione-related pathways and biomarkers, such as High GPX3 expression in epithelial ovarian cancers, and GSH is profoundly associated with chemoresistance, that could lead to novel therapeutic interventions. The investigation into Glutathione transferase P1 as a promising therapeutic target in ovarian cancer is one such example. As our understanding deepens, the strategic manipulation of glutathione pathways may offer new avenues for enhancing the efficacy of ovarian cancer treatments and improving patient prognoses, even presenting as a potential strategy to counter the poor prognosis of ovarian cancer. Ultimately, the goal is to harness the beneficial aspects of glutathione while simultaneously overcoming its resistance-promoting capabilities to achieve better control over this challenging disease.
