Dendrograms of hierarchical clusterings based on 1 – Pearson correlation coefficient metrics. The expression levels of 169 Ensembl gene IDs with correlation coefficients >0.445 for which data were available in all three comparisons across 23 cell lines measured in each assay were utilized to cluster the data into three individual clusters. The cell lines are colored depending on their origins; red, deep-red, grey, green and blue indicate cells of: lymphoid; myeloid; melanoma, glioma and sarcoma; carcinoma and neuronal origins, respectively.
