Human antigen R (HuR) is an RNA-binding protein (RBP) belonging to the human embryonic lethal abnormal visual (ELAV) protein family that was originally identified as a specific antigen in patients with paraneoplastic neurological symptoms [ 1, 2

HuR, a protein that binds to specific mRNA subsets, is increasingly recognized as a pivotal posttranscriptional regulator of gene expression. Here, HuR was immunoprecipitated under conditions that preserved HuR-RNA interactions, and HuR-bound target mRNAs were identified by cDNA array hybridization.

Several RBPs have been reported as 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. Human antigen R (HuR) is an RNA-binding protein that regulates the stability, translation, and nucleus-to-cytoplasm shuttling of its target mRNAs. 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. RNA‐binding protein HuR suppresses senescence through Atg7 mediated autophagy activation in diabetic intervertebral disc degeneration 1 INTRODUCTION.

Hu proteins possess three RNA-recognition motifs through which they bind with high affinity and specificity to target Posttranscriptional gene regulation by RNA-binding proteins, such as HuR (elavl1), fine-tune gene expression in T cells, leading to powerful effects on immune responses. HuR can stabilize target mRNAs and/or promote translation by interacting with their 39 untranslated region adenylate and uridylate–rich elements. Human antigen R (HuR) is an RNA-binding protein (RBP) belonging to the human embryonic lethal abnormal visual (ELAV) protein family that was originally identified as a specific antigen in patients with paraneoplastic neurological symptoms [ 1, 2 The RNA-binding protein (RBP) Hu-antigen R (HuR) is a central player in posttranscriptional regulation of cancer-related gene expression, and contributes to tumorigenesis, tumor growth, metastasis, and drug resistance. While many RNA‐binding proteins have been shown to bind to AREs in vitro, neither the functional consequences nor the physiological significance of their interactions are known. Here we demonstrate a role for the embryonic lethal abnormal visual (ELAV) RNA‐binding protein HuR in mRNA turnover in vivo. Background: The RNA-binding protein HuR is involved in a range of cellular processes and several diseases.Results: We reveal the characteristics of HuR binding using genomic methods and explore its network of targets.Conclusion: Our results reveal the complexity of RBP binding, corroborate the concept of post-transcriptional networks and suggest an interplay between miRNAs and RBPs Human antigen R (HuR) is an RNA binding protein that binds to the AU-rich element (ARE) of specific mRNA and is involved in the export and stabilization of ARE-mRNA. Our recent report unveiled that the E4orf6 gene deleted oncolytic adenovirus (dl355) replicated for certain types of cancers where ARE-mRNA is stabilized.

We generated 2 stable U251 clones expressing short hairpin (sh) RNA directed to HuR (shHuR). A scrambled sequence was utilized to generate control (shControl) clones.

Albeit the suppression of mRNA translation may derive from eIF3a binding to the 5′-UTRs of target mRNAs, how eIF3a may accelerate mRNA translation remains unknown. In this study, we show that eIF3a up-regulates translation of Chk1 but not Chk2 mRNA by interacting with HuR, which binds directly to the 3′-UTR of Chk1 mRNA.

Oct 2, 2017 HuR (ELAVL1), a RNA-binding protein, plays a key role in posttranscriptional regulation of multidrug resistance (MDR)-related genes. Among 

Even though the transcriptional activation of ABCA1 is well established, the posttranscriptional regulation of ABCA1 expression is poorly understood. Here, we investigate the potential contribution of the RNA binding protein (RBP) human antigen R (HuR) on the posttranscriptional regulation of ABCA1 expression 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. import of proteins. KEY WORDS: HuR, RNA stability, Nuclear import, Retinoic acid, Cellular retinoic acid-binding protein, NFκB INTRODUCTION One of the best-characterized RNA-binding proteins in animals is HuR (encoded for by Elavl1), a ubiquitously-expressed member of the embryonic lethal abnormal vision (ELAV)/Hu family of RNA-binding proteins.

Human antigen R protein modulates vascular endothelial growth factor expression in human corneal epithelial cells under hypoxia. 2011-12-27 · Several studies have linked the RNA-binding protein HuR, which increases mRNA stability, with malignant transformation. However, in this issue of the JCI, Yiakouvaki et al. compellingly demonstrate in mice that increased HuR activity in myeloid cells has a protective role in the onset of pathologic intestinal inflammation (i.e., colitis) and colitis-associated cancer (CAC).

RNA-binding protein that binds to the 3'-UTR region of mRNAs and increases their stability (PubMed:14517288, PubMed:18285462, PubMed:31358969). Involved in embryonic stem cells (ESCs) differentiation: preferentially binds mRNAs that are not methylated by N6-methyladenosine (m6A), stabilizing them, promoting ESCs differentiation (By similarity).

The elevated MEF 2C transcriptionally enhances SCN 5A mRNA expression. The RNA binding protein (RBP) HuR (ELAVL1) is an established regulator of post‐transcriptional gene regulation and is overexpressed in most human cancers. In many cancerous settings, HuR is not only overexpressed, but it is “overactive” as denoted by increased subcellular localization within the cytoplasm. 2019-12-03 · Herein, we show that the ablation of RNA-binding protein HuR in NSCs impairs adult but not embryonic neurogenesis.
