Figure 4

Schematic figure of the overall experimental design and the results of this study. In the upper left corner the investigated candidate reference genes are shown in grey except for the novel reference genes SNW1 and CNOT4, which are shown in yellow. The investigated cell lines are depicted in the lower left corner. Cancer cell lines are colored red, while normal cell lines are colored blue. On the right side the top-ranking reference genes are illustrated for cancer cell lines in red circle, for normal cell lines in blue circle and for all cell lines in green circle. The most stable gene upon serum starvation is shown in brown circle. The methods used for performing the experiments and the software used for the evaluation of the results are depicted as a yellow arrow.
