PRICKLE1 and cancer: Mechanistically, these KDM1A inhibitors negatively regulate the Wnt/β-catenin pathway through enrichment of activating H3K4me1/2 marks in the promoter of the Wnt antagonists Prickle1, APC and Sfrp5.200 This finding is consistent with the results reported by Lei et al., which indicated that knockdown of KDM1A sensitizes HCC cancer cells to cisplatin and sorafenib by increasing the expression of several suppressors of β-catenin signaling, especially Prickle1 and APC.201
