5. Plaque psoriasis-induced ChIP-Seq node HCT intersection network

OVERVIEW
This network computes the extent and significance of intersections between (i) psoriasis-induced (FC%gt;1.5) confidence transcriptional targets (CTs) and (ii) high confidence transcriptional targets (HCTs) computed from ChIP-Seq consensomes for a set of signaling pathway nodes. PICTS are defined as genes with a plaque psoriasis consensome mean fold change >1.5 and a plaque psoriasis consensome q-value (FDR-corrected p-value) <0.05. Please refer to the plaque psoriasis consensome for additional details.

METHODS
PICTs were computed against HCTs derived from ChIP-Seq consensomes for a range of pathway nodes using the GeneOverlap package implemented in R. Intersections between PICTs and node ChIP-Seq HCTs were assigned an FDR-corrected p-value (Q-VALUE), which corresponds to the probability that the intersection size is due to a random event.

INTERPRETATION
Cellular signaling pathway nodes (circles) in this network are organized according to SPP’s signaling pathway node-centric classification, which classifies nodes as receptors, enzymes, transcription factors, ion channels or co-nodes. Nodes are colored according to the category they belong to: orange = receptors; blue = enzymes; green = transcription factors; mustard = ion channels; grey = co-nodes. Nodes are grouped into functional classes in each category (rectangles). Node sizes are proportional to the -LOG10 of the intersection q-value: the larger the node the lower the q-value and the greater the confidence of the intersection between that node’s HCTs and PICTs. Clicking a node will pull up a pane showing details on the data point, including the number of genes in the intersection of its HCTs and PICTs.
