A scrambled sequence was utilized to generate control (shControl) clones. Effective and specific knockdown of HuR was observed at the mRNA and protein levels (Supplementary Fig. S1). Human antigen R (HuR) is an RNA-binding protein that posttranscriptionally regulates many cancer-trait genes. CDC6, a central regulator of DNA replication, is regulated by HuR. In this study, we investigated the role of HuR in colorectal cancer tumorigenesis and oxaliplatin (L-OHP) resistance, as well as the underlying mechanisms involving CDC6. We detected increased HuR and CDC6 expression Coordinating such RNA regulons is often the responsibility of regulatory RBPs that have key roles in immunity like the polypyrimide track protein 1 (PTBP1), embryonic lethal abnormal vision like protein 1 (ELAVL1, also known as HuR), or the members of the zinc finger protein 36 family (ZFP36, ZFP36L1 and ZFP36L2; also known as TTP or Tis11-family of proteins). The RNA-binding protein HuR associates with the p53 mRNA, as reported previously, and with the NPM mRNA, computationally predicted to be a target of HuR. Here, we show that HuR binds the NPM and p53 3′-untranslated regions and stabilizes these mRNAs in polyamine-depleted intestinal epithelial cells.

HuR is composed by three RNA recognition motifs, namely RRM1, RRM2, and RRM3. The two N-terminal RRM domains are disposed in tandem and contribute mostly to HuR interaction with adenine and uracil-rich elements (ARE) in mRNA.

Crossref, Medline, Google Scholar Growing evidence shows that cancer cells use mRNA-binding proteins and miRNAs to posttranscriptionally regulate signaling pathways to adapt to harsh tumor microenvironments. In ovarian cancer, cytoplasmic accumulation of mRNA-binding protein HuR (ELAVL1) is associated with poor prognosis.

The mammalian RNA-binding protein (RBP) HuR associates with numerous mRNAs encoding proteins with roles in cell division, cell survival, immune response, and differentiation. HuR was known to stabilize many of these mRNAs and/or modulated their translation, but the molecular processes by which HuR affected the fate of target mRNAs was largely unknown.

While HuR is normally localized within the nucleus, it has been shown that HuR binds mRNAs in the nucleus and then escorts the mRNAs to the cytoplasm where HuR protects them from degradation.

HuR/ELAVL1 is an RNA-binding protein involved in differentiation and stress response that acts primarily by stabilizing messenger RNA (mRNA) targets. HuR comprises three RNA recognition motifs (RRMs) where the structure and RNA binding of RRM3 and of full-length HuR remain poorly understood.

HuR is an RNA-binding protein that resides predominantly in the nucleus but shuttles to the cytosol carrying mRNAs containing a uridylate-rich region in the 3'untranslated region.

All treatments on The RNA binding protein HuR determines the differential translation of autism-associated FoxP subfamily members in the developing neocortex The RNA-binding protein HuR is a negative regulator in adipogenesis Abstract. Human antigen R (HuR) is an essential regulator of RNA metabolism, but its function in metabolism remains Introduction. Obesity is characterized by excessive lipid storage in adipose tissue, leading to an increase of The RNA-binding protein HuR binds to elements rich in adenylate and uridylate (AU-rich elements) in target mRNAs and stabilizes them against degradation. The complete spectrum of genes whose expression is regulated by HuR and are the basis for the broad range of cellular functions of the protein is incompletely understood. HuR, a member of the ELAV family of RNA-binding proteins, is a multifunctional protein that has been implicated in the regulation of various aspects of RNA metabolism (Hinman and Lou, 2008). Although primarily known for binding to the 3′ UTRs of mRNAs and increasing their intrinsic stability, several recent reports identified HuR as a bona fide translational regulator as well.
