Multiple functions of HuR in urinary tumors
- 59 Downloads
Human embryonic lethal abnormal visual-like protein, HuR, belongs to a member of the Hu family of RNA-binding protein and plays a critical role in urinary tumors. The purpose of this review is to summarize the current literature to demonstrate the importance of HuR in urinary tract tumors’ biology and explore the potential role in therapeutic strategies aimed at targeting this molecule in cancer cells.
The relevant literature from PubMed and Medline databases is reviewed in this article.
Increasing evidence supports that HuR plays a critical role in urinary tumors’ biology because it regulates the expression of many urinary tumors-associated molecules through post-transcriptional regulatory mechanisms (including mRNA trafficking, mRNA decay and protein translation). Recent studies have demonstrated that HuR is associated with chemoresistance of urinary tumors, suggesting that HuR might be a novel therapeutic target and a marker for therapeutic response and prognosis assessment.
HuR is associated with various urinary tumors biological characteristics. Targeted therapy of HuR may become an attractive treatment strategy. What’s more, more preclinical and clinical trials of this targeted strategy are necessary for the treatment of urinary tumors.
