Copper accumulation in the synovial membrane and cartilage has been suggested as the major cause of osteoarthritis and accelerated degenerative changes with deformities affecting particularly larger joints 90

A 2020 study in the Journal of Molecular Medicine demonstrated that BPC-157 activates both VEGF-dependent and VEGF-independent pathways to nitric oxide production, supporting blood vessel formation and vascular stability in damaged tissue

Normally, the transcription factor Nrf2 and its inhibitory protein KEAP1 are tightly bound to inhibit activity, but in the presence of ROS, a conformational change in KEAP1 results in the release of NRF2, which binds to the antioxidant response element (ARE) and activates the downstream genes heme oxygenase-1 (HO-1), glutathione peroxidase 4 (GPX4), quinone oxidoreductase1(NQO1), thioredoxin reductase 1 (SRXN1), and transcription of solute carrier family 7 member 11 (SLC7A11), which enhance cellular antioxidant defenses and inhibit ferroptosis (Wang et al., 2022

Other distinct mitochondrial sites associated with substrate oxidation and oxidative phosphorylation leak electrons to oxygen to produce superoxide or hydrogen peroxide, and these include oxoacid dehydrogenase complexes that shuttle electrons to NAD + [6]
