PDRN (Polydeoxyribonucleotide) is a deoxynucleotide polymer mainly derived from the sperm of rainbow trout or salmon. PDRN inhibits pro-inflammatory factors and promotes VEGF expression via the cAMP-PKA pathway by activating the adenosine A_2A receptor (A_2AR), thereby driving angiogenesis and collagen deposition in fibroblasts. Degradation products of PDRN provide DNA raw materials for proliferating cells through the salvage synthesis pathway, accelerating re-epithelialization. PDRN reduces melanin synthesis and cell apoptosis by upregulating ERK/AKT phosphorylation and inhibiting the activities of MITF and tyrosinase, and resists skin aging by attenuating nuclear autophagy and blocking the interaction between LC3-SIRT1. PDRN is mainly used for wound repair, post-aesthetic surgery recovery and anti-aging research.
