a Principal component analysis of SK-ChA-1 cells that were either untreated (in red), incubated with 500 μM ZnPC-ITLs (final lipid concentration) and kept in the dark (ITL, in green), or treated with 500-mW (ITL 500, in orange) or 50-mW (ITL 50, in purple) laser light. The extent to which a principal component (PC) accounts for the variability in the data is indicated in parentheses. b Venn diagram showing the number of non-overlapping upregulated and downregulated genes per group (in-circle values) and the number of overlapping upregulated and downregulated genes (values in the respective overlapping region) between the various treatment groups compared to the control group. The total number of genes that were up- and downregulated per group comprises the sum of all regions in a given circle
