The experiment performed by Braun et al.  consists of knocking down several permutations of the target's degradation factors. The "Control (-)" data result from an experimental setup in which the miR9-b is not expressed; the "PAN3 & NOT1 KD" data result from an experimental setup in which only the miR9-b is expressed but both NOT1 and PAN3 are knocked down; the "NOT1 KD" data result from a setup in which miR9-b and PAN3 are expressed while NOT1 is knocked down; the "PAN3 KD" data result from a setup in which miR9-b and NOT1 are expressed while PAN3 is knocked-down; the "Control (+)" data result from a setup in which all three factors are expressed. The data have been extracted from figure 7A of . The numerical values are reported in the Additional file 1.
