Table 5 Most significant gene sets enriched in PC2 correlating genes. (a) Table is a subset of gene sets (ten out of 23) significantly (FDR q-value < 1 %) enriched in PC2 positively correlating genes, which were upregulated in EKCs, by PC-GSEA (for full data, see Additional file 10: Table S7). (b) Table is gene sets significantly enriched in PC2 negatively correlating genes, which were upregulated in HaCaTs. SIZE is number of genes belonging the gene set. NES is normalized enrichment score
