Role of Pirin, an Oxidative Stress Sensor Protein, in Epithelial Carcinogenesis

Abstract

Pirin is an oxidative stress (OS) sensor belonging to the functionally diverse cupin superfamily of proteins. Pirin is a suggested quercetinase and transcriptional activator of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway. Its biological role in cancer development remains as a novel area of study. This review shows accumulating evidence on the contribution of Pirin in epithelial cancers, signaling pathways involved, and as a suggested therapeutic target. Finally, we propose a model in which Pirin is upregulated by physical, chemical or biological factors involved in OS and cancer development.
