Statistical analysis and functional annotation of genes correlated to REGγ. (A) Distribution of PCC (Pearson correlation coefficient) in datasets from different cancers. Upper panel box-plot shows positive PCC and lower panel displays negative PCC values (Y axis) that are greater than +0.6 or less than -0.6. Analyzed datasets are from colon (n = 3), liver (n = 4), lung (n = 3) and thyroid (n = 3). (B) Most of the annotated REGγ-correlated gene pathways are involved in cancers. Ingenuity analysis of REGγ-correlated gene pathways were grouped into cancer (black, 10%), cancer related (grey, 49%) and other pathway clusters (white, 41%) to reveal the proportion of REGγ-correlated gene pathways in cancers. (C) Most of the annotated REGγ-correlated genes are cancer-related. The genes representing cancer, cancer related and other-pathway clusters were plotted to show the overlaps among different pathway clusters. Note that the total number of cancer and cancer-related genes constitute majority of the REGγ-correlated genes.
