Reductive capacity of ARPE-19 cells as a function of the degree of AtRal degradation. The reductive activity was measured by MTT assay 24 h after 60 min incubation with 0.05 mM AtRal photodegraded by visible light for the indicated time (a) leading to the indicated loss of AtRal (b). During exposure to AtRal/degraded AtRal cells were kept in dark (dark) or exposed to visible light (~12 mW cm−2; light). Cells without AtRal/dAtRal were used as controls corresponding to 100% reductive capacity.
