The usage of a rich medium (2xYT) in combination with a prolonged expression time (65 hours) at 20 C led to a substantial increase in jr PPO1-wt yield

The primary molecular actions relevant to skin are: modulation of TGF- signaling (upregulating TGF-1 for collagen I/III synthesis while suppressing TGF-2 to prevent scarring), decorin upregulation for orderly collagen fibril assembly, MMP suppression paired with TIMP upregulation to preserve ECM integrity, and copper-dependent lysyl oxidase activation for collagen crosslinking
