Figure Lengend Snippet: Heatmap of transcriptional responses of hypoxia- and HIF-regulated genes in renal cell carcinoma cell lines following pharmacological inhibition of the HIF pathway. The heatmap shows log 2 (fold change) values of mRNA expression relative to vehicle-treated controls (DMSO) for 786-O and Caki-1 cells after 72 h of treatment with KC7F2, GN44028, FM19G11, or sunitinib (SUN) at IC 50 concentrations. Normal proximal tubule cells (HK-2) were excluded from visualisation. All qPCR data are presented as log 2 fold change relative to the vehicle-treated controls (DMSO). Red, green, and white colours indicate downregulation, upregulation, and no change in expression, respectively. The colour scale represents log 2 FC values ranging from −5 to +5. Genes were hierarchically clustered (average linkage, Euclidean distance), and treatment conditions were ordered manually. Each value represents the mean of two independent biological experiments, each with three technical replicates.
