Covalent Targeting of Glutamate Cysteine Ligase to Inhibit Glutathione Synthesis. [PDF]
Chembiochem, 2023 Abstract Dysregulated oxidative stress plays a major role in cancer pathogenesis and some types of cancer cells are particularly vulnerable to inhibition of their cellular antioxidant capacity. Glutamate‐cysteine ligase (GCL) is the first and rate‐limiting step in the synthesis of the major cellular antioxidant glutathione (GSH ...

Non-canonical Glutamate-Cysteine Ligase Activity Protects against Ferroptosis. [PDF]
Cell Metab, 2021 Cysteine is required for maintaining cellular redox homeostasis in both normal and transformed cells. Deprivation of cysteine induces the iron-dependent form of cell death known as ferroptosis; however, the metabolic consequences of cysteine starvation beyond impairment of glutathione synthesis are poorly characterized.

Tuberous sclerosis complex neuropathology requires glutamate-cysteine ligase. [PDF]
Acta Neuropathol Commun, 2015 Tuberous sclerosis complex (TSC) is a genetic disease resulting from mutation in TSC1 or TSC2 and subsequent hyperactivation of mammalian Target of Rapamycin (mTOR). Common TSC features include brain lesions, such as cortical tubers and subependymal giant cell astrocytomas (SEGAs).

Altered glutamate cysteine ligase expression and activity in renal cell carcinoma. [PDF]
Biomed Rep, 2014 Oxidative stress has been linked to the progression of mutations and cancer. Increased glutathione (GSH) contents have been observed in a number of different human cancer tissues. GSH is synthesized de novo in a two-step process catalyzed by glutamate cysteine ligase (GCL).

Characterization of a glutamate-cysteine ligase in Bombyx mori
Molecular Biology Reports, 2022 Abstract Background: Glutamate cysteine ligase (GCL) is a crucial enzyme involved in the synthesis of glutathione (GSH). Despite various studies on glutathione transferase and its essential role in detoxification and resistance to oxidative stress, GSH synthesis has not been described in silkworms to date.

Probiotics prevent intestinal barrier dysfunction in acute pancreatitis in rats via induction of ileal mucosal glutathione biosynthesis. [PDF]
PLoS ONE, 2009 BACKGROUND: During acute pancreatitis (AP), oxidative stress contributes to intestinal barrier failure. We studied actions of multispecies probiotics on barrier dysfunction and oxidative stress in experimental AP.
