Fig. 4From: Low-power photodynamic therapy induces survival signaling in perihilar cholangiocarcinoma cellsTop upregulated and downregulated PDT-induced genes as expressed by the log2 fold-change in gene expression in the ITL 50 (a) and ITL 500 group (b) compared to the control group. Genes were ordered by decreasing absolute log2 fold-change. Values are presented as the mean of n = 3 per groupBack to article page
