Enzymes such as glutamate dehydrogenase replenish TCA intermediates and provide glutamate for GSH synthesis

Clinical Evidence in the Matrixyl vs GHK-Cu Comparison Evaluating the clinical evidence in the Matrixyl vs GHK-Cu literature requires distinguishing between cosmetic clinical trials (which evaluate consumer-visible outcomes like wrinkle depth) and biomarker-based research studies (which measure gene expression, protein synthesis, and cellular function)

In male patients with KRAS-mutant CRC, decreased ferritin activity has also been observed, suggesting that these tumors may depend on mitochondrial redox-buffering mechanisms to evade iron-dependent cytotoxic responses [5, 72, 73]
