Figure Lengend Snippet: Pathway analysis of key genes being up- or down-regulated on the transcript level upon 48 h of chemerin (huChem-157) treatment in OVCAR-3 cells as assessed by Affymetrix Clariom S human microarrays. Most of the up-regulated genes (red) are IFNα-response genes, with IRF9 as the key mediator of IFNα-induced gene regulation (as part of the ISGF3 complex, not shown). The observed regulation pattern is predicted to lead to growth inhibition of tumor cells (Ingenuity pathway analysis (IPA) software, Qiagen) (see discussion section). Broken arrows indicate transcriptional activation, other arrows protein interaction. The color intensity represents the measured grade of mRNA up- (red) or down-regulation (green).
Article Snippet: Since pathway analyses strongly suggested IFNα to be the activator of most genes regulated after chemerin treatment in all cell lines tested, but we did not observe any induction of IFNα on the mRNA level itself, we tested the effect of this adipokine on the IFNα protein concentrations in cell culture supernatants using ELISA (DFNAS0, R&D Systems).
