Metabolic and Signaling Pathways Affected by Photodynamic Therapy (PDT) with Protoporphyrin IX
Protoporphyrin IX (PpIX) occupies a unique nexus in photodynamic therapy (PDT) by bridging the endogenous metabolism of heme biosynthesis with highly efficient, light-induced cytotoxicity. Administered via its precursor 5-aminolevulinic acid (5-ALA) or its derivatives, intracellularly generated PpIX undergoes intersyst...
