The first rate-limiting step in the synthesis of both GSH and hGSH is the formation of -glutamylcysteine (-Glu-Cys) catalyzed by -glutamylcysteine synthetase (-ECS, encoded by GSH1 )
reported significant enrichment of 15 REEs, including Ce, La, and Nd, in tumor tissues compared to adjacent normal tissues, suggesting a possible association with the lung cancer microenvironment, although the biological significance of this finding remains to be further clarified (78)
All experiments were performed in triplicate under low-light conditions to minimize DPPH degradation
