Abstract

Proteins that bind to DNA/RNA are typically evolutionarily conserved with multiple regulatory functions in transcription initiation, mRNA translation, stability of RNAs, and RNA splicing. Therefore, dysregulation of DNA/RNA binding proteins such as purine-rich element binding protein alpha (PURα) disrupts signaling transduction and often leads to human diseases including cancer. PURα was initially recognized as a tumor suppressor in acute myeloid leukemia (AML) and prostate cancer (PC). Most recently, several studies have revealed that PURα is dysregulated in multiple cancers, such as breast cancer (BC) and esophageal squamous cell carcinoma (ESCC). The oncogenic or tumor-suppressive functions of PURα are realized via regulating RNA/protein interaction, mRNA translation, formation of stress granules (SGs), and transcriptional regulation of several oncogenes and tumor suppressors. Although DNA/RNA binding proteins are hardly targeted, novel strategies have been applied to identify compounds targeting PURα and have demonstrated promising anti-tumor efficacy in the preclinical study. The present review summarizes the most recently discovered critical roles of PURα in various cancer types, providing an overview of the biomarker and therapeutic target potential of PURα for patients with cancer.

期刊介绍: Molecular Medicine is an open access journal that focuses on publishing recent findings related to disease pathogenesis at the molecular or physiological level. These insights can potentially contribute to the development of specific tools for disease diagnosis, treatment, or prevention. The journal considers manuscripts that present material pertinent to the genetic, molecular, or cellular underpinnings of critical physiological or disease processes. Submissions to Molecular Medicine are expected to elucidate the broader implications of the research findings for human disease and medicine in a manner that is accessible to a wide audience.
