NFKB1 and pancreatic serous cystadenoma: Pathways found to be enriched in the comparison of PsA to PsC included multiple pathways for NF‐κB signaling (adjusted P = 1.4 × 10−45) and Wnt signaling (adjusted P = 9.5 × 10−58), which provides compelling evidence that these pathways are potentially involved in the development of PsA.
