Figure 6From: The l1-l2 regularization framework unmasks the hypoxia signature hidden in the transcriptome of a set of heterogeneous neuroblastoma cell linesHeatmap for the ε = 100 signature with frequency cut at 50%. Normalized expressions for the 11 selected probesets in the 18 samples, listed at the bottom of the figure, representing the 9 cell lines in normoxic (N) or hypoxic (H) conditions. Red hues correspond to high expression, while blue indicates low expression values.Back to article page
