Although these data suggest that GSH depletion per se, at least for a short period of time, is not sufficient to cause cell injury, a prolonged depletion of mucosal GSH leads to severe degeneration of intestinal mucosal epithelial cells, as shown in BSO-treated mice (Martensson et al, 1990)
For tonic NMDAR-mediated current recording, neurons were held at + 40 mV in normal ACSF with internal solution containing (in mM): 110 Cs methylsulfate, 20 TEA-Cl, 15 CsCl, 4 ATP-Mg, 0.3 Na3-GTP, 0.5 EGTA, 10 HEPES, 4.0 QX-314, and 1.0 spermine, pH adjusted to 7.2 with CsOH, and osmolality set to 290300 mOsm/kg with sucrose

(65) L-methionine This is a sulfur-containing amino acid that helps build protein, synthesizes other critical amino acids (cysteine and taurine), and produces important molecules in the body, including glutathione and a naturally-occurring antidepressant called S-Adenosyl-L-methionine (SAMe low levels have been found in liver disease and depression)
Most longevity peptides (BPC-157, MOTS-c, GHK-Cu) have been studied mainly in animals, not humans
