Transcriptional signatures across samples. Clustered heatmap showing expression of A wnt signature genes and B hedgehog signature genes, across samples in the study. All expression values are Zscore normalized. Zscore <-1 are blue, Z-score > 1 are red with a graded coloring through white at 0. Sample names are on the x-axis, they are clustered by expression pattern and samples with high signature scores are to the right. Samples with somatic nonsynonymous APC mutations (A) or PTCH1 mutations (B) and denoted by an asterisk above the heatmaps. WNT signature genes (top to bottom): FSTL1, DACT1, CD99, LMNA, SERPINE1, TNFAIP3, GNAI2, ID2, MVP, ACTN4, CAPN1, LUZP1, MTA1, RPS19, PTPRE, AXIN2, NKD2, SFRS6, CCND1, SCAP, CPSF4, SENP2, DKK1, PRKCSH, SLC1A5, HDGF, CBX3, SCML1, PCNA, RPS11, SNRPA1, TGM2, LY6E, IFITM1, NSMAF, TCF20, BCAP31, AXIN1, AGRN, PLEKHA1, SLC2A1, CTNNB1, EIF5A, IMPDH2, GSK3B, PFN1, UBE, MAP3K11, ARHGDIA, HNRPUL1, FLOT2, GYPC, NCOA3, CENTB1, SYK, POLR2A, KRT5, DHX36, ELF1, SMG2, FGD6, MAPKAP1, LOC389435, RPL27A, SRP19, RPL39L, SFRS2IP, FUSIP1; Hedgehog signature genes (top to bottom): LRFN4, JAG2, RPL29, WNT5A, SNAI2, FST, MYCN, BMP4, CCND1, BMI1, CFLAR, PRDM1, GREM1, FOXF1, CCND2, CD44.
