Glutathione (GSH) is a thiol antioxidant that scavenges reactive oxygen species (ROS), resulting in the formation of oxidized glutathione (GSSG). Decreased amounts of GSH and a decreased GSH/GSSG ratio in tissues are biomarkers of oxidative stress.
Glutathione is a powerful antioxidant found in every cell of the body, composed of three amino acids: cysteine, glutamine, and glycine. It plays a crucial role in protecting cells from oxidative stress, detoxifying harmful substances, and supporting the immune system.
cancer cells can have elevated levels of glutathione, which may help them survive in the oxidative environment created by the immune response and chemotherapy. This can make cancer cells more resistant to treatment.
While glutathione can be obtained from certain foods (like fruits, vegetables, and meats), its absorption from supplements is debated. Some people take N-acetylcysteine (NAC) or other precursors to boost glutathione levels, but the effects on cancer prevention or treatment are still being studied.
Depleting glutathione (GSH) to raise reactive oxygen species (ROS) is a strategy that has been explored in cancer research and therapy.
Many cancer cells have altered redox states and may rely on GSH to survive. Increasing ROS levels can induce stress in these cells, potentially leading to cell death.
Certain drugs and compounds can deplete GSH levels. For example, agents like buthionine sulfoximine (BSO) inhibit the synthesis of GSH, leading to its depletion.
Cancer cells tend to exhibit higher levels of intracellular GSH, possibly as an adaptive response to a higher metabolism and thus higher steady-state levels of reactive oxygen species (ROS).

"...intracellular glutathione (GSH) exhibits an astounding antioxidant activity in scavenging reactive oxygen species (ROS)..."
"Cancer cells have a high level of GSH compared to normal cells."
"...cancer cells are affluent with high antioxidant levels, especially with GSH, whose appearance at an elevated concentration of ∼10 mM (10 times less in normal cells) detoxifies the cancer cells." "Therefore, GSH depletion can be assumed to be the key strategy to amplify the oxidative stress in cancer cells, enhancing the destruction of cancer cells by fruitful cancer therapy."

The loss of GSH is broadly known to be directly related to the apoptosis progression.

eff↓, These activities were lost during freeze or vacuum drying, suggesting that the main anti-cancer compounds in GE are volatile.
ChemoSen↑, We found that GE enhanced the activities of chemotherapeutics
ER Stress↑, Our data indicate that the reduced proliferation of the cancer cells treated by GE is at least partly mediated by increased endoplasmic reticulum (ER) stress.
tumCV↓, homemade GE was found to reduce the viability of the two multiple myeloma (MM) cell lines, RPMI-8226 and JJN3, as well as the prostate cancer cell line DU145 in a dose-dependent manner,
DNAdam↑, GE alone slightly increased the percentage of tail DNA (% Tail) (representing cumulative levels of abasic sites, as well as single- and double-strand DNA breaks) measured at day one, compared to untreated cells
GSH∅, We could not detect any changes in cellular GSH levels after treatments with GE
HSP70/HSPA5↓, ; however, in support of increased ER stress after GE treatment, we detected an increased pulldown of HSPA5 (BIP), a member of the Hsp70 family
UPR↑, s leading to the accumulation of unfolded proteins in the ER (also known as GRP78)
β-catenin/ZEB1↓, we also found a reduction in the β-catenin leve
ROS↑, In further support for increased ER stress induced by GE, which will lead to elevated ROS-levels and oxidative stress
HO-2↑, we found a significant increase in proteins activated by and important for regulating cellular ROS levels, e.g., OXR1, Txnl1, Hmox2, and Sirt1
SIRT1↑,
GlucoseCon∅, glucose consumption, as well as lactate secretion, were not changed.
