Abstract
Background: Quercetin inhibits prostate cancer growth, but its mechanisms are not fully elucidated. Results: Quercetin binds to hnRNPA1 and hampers its return to the nucleus, causing accumulation of hnRNPA1 in the cytoplasm. Conclusion: hnRNPA1 is a target of quercetin, driving cells toward apoptosis through expression regulation of cIAP1. Significance: Understanding of the novel mechanism of actions on quercetin is crucial for cancer prevention and treatment in prostate cancer. ? 2014 by The American Society for Biochemistry and Molecular Biology, Inc.
