Description
Aim was to identify novel targets of protoporphyrin-IX (PpIX) after silencing Ferrochelatase (FECH) enzyme. PpIX is a light sensitive metabolite of heme synthesis. Generation of PpIX is increased if FECH activity is suppressed. Here, silencing of FECH leads to down-regulation of PpIX, measured by a decrease of PpIX-specific fluorescence.
