In these studies, researchers evaluate whether BPC-157 or GHK-Cu causes DNA damage or has the potential to promote cancerous growth

This bidirectional regulation suggests sophisticated sensing of tissue microenvironmental cues, enabling GHK-Cu to normalize MMP activity toward homeostatic levels rather than exerting uniform stimulatory or inhibitory effects

A revised concept of cuproptosis incorporates ROS, particularly hydroxyl radicals, which convert copper ions into reactive intermediates such as copper peroxyl, copper hydroperoxyl, and copper superoxyl species
