While both peptides bind to the GHRH receptor, their different structures and durations of action could potentially influence downstream signaling cascades in slightly different ways

Endosomes (Micrococcus Lysate): The liposome-encapsulated DNA repair enzyme UV-endonuclease, derived from the marine microorganism Micrococcus Lysate
have demonstrated that Se nanoparticles (TSIIA@SeNPsAPS), derived from the active ingredients of traditional Chinese medicine, not only alleviate mitochondrial damage and Sphase cell cycle arrest in PC12 cells by reducing ROS levels at the cellular level but also enhance the expression of the antioxidant selenoprotein GPX and decrease lipid peroxidation products (MDA) at the animal level, thereby exhibiting therapeutic effects on SCI (Figure 9D) [188]
GHK-Cu is, in effect, a delivery vehicle that pairs a signaling peptide with the trace metal those enzymes need
