dc.description.abstract© 2020 Elsevier Inc.PIN1, the peptidyl-prolyl isomerase (PPIase), is an enzyme that changes the conformation of phosphoproteins. The conformational change induced by PIN1 alters the function and stability of the target proteins. PIN1 is overexpressed in many different types of malignancies, including breast, lung, cervical, brain and colorectal tumors. PIN1 overexpression has been associated with activation of multiple oncogenic signaling pathways during tumor development. Hypoxia-inducible factor 2α (HIF-2α), a transcription factor activated in hypoxia, plays a role in erythropoiesis, glycolysis, tissue invasion, metastasis and angiogenesis. In this study, we found the direct interaction between HIF-2α and PIN1 in colorectal cancer HCT116 cells. Notably, serine 16 and lysine 63 residues of PIN1 were critical for its interaction with HIF-2α. When PIN1 protein was silenced by transient transfection of PIN1 short interfering RNA, the expression of HIF-2α was attenuated under a hypoxic condition. Moreover, genetic and pharmacologic inhibition of PIN1 abrogated the expression of vascular endothelial growth factor and angiogenesis. The cycloheximide chase experiment revealed the stabilization of HIF-2α by PIN1. Both WW and PPIase domains of PIN1 appear to be critical for its interaction with HIF-2α.-
