Article Title: Exploratory Multi-Level Analysis of the HIF Axis in Clear-Cell Renal Cell Carcinoma and Evaluation of GN44028 as an Experimental HIF Pathway-Modulating Compound

Figure Lengend Snippet: Cytotoxicity of HIF inhibitors and sunitinib in renal cell lines: ( A ) 786-O, ( B ) Caki-1, and ( C ) HK-2. Dose–response curves (SRB, 72 h of incubation). Data are presented as mean ± SD from independent biological experiments, each measured in technical replicates ( n = 6). Curves were fitted using four-parameter logistic regression.

Article Snippet: 786-O (cRL1932TM), Caki-1 (McCoy) human renal cell carcinoma lines, and HK-2 (cRL2190TM) human proximal kidney tubule-derived cell lines were obtained from the American Type Culture Collection (ATCC, Manassas, VA, USA).

Figure Lengend Snippet: Cell cycle analysis by propidium iodide staining and flow cytometry in 786-O ( A ), Caki-1 ( B ), and HK-2 ( C ) cells treated with KC7F2, FM19G11, GN44028, and sunitinib at IC 50 concentrations for 24 h. Bar graphs show mean ± SD from independent biological experiments, each measured in technical replicates ( n = 3–19). GN44028 was associated with an increased sub-G1 fraction in ccRCC cell lines and G2/M arrest in HK-2 cells. Sunitinib induces G0/G1 arrest in 786-O cells. **** p < 0.0001, * p < 0.05 vs. DMSO (ANOVA with Dunnett’s test).

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.
