  • MicroRNAs are small non-coding RNAs transcribed from our DNA. (sciencedaily.com)
  • Small interfering RNA, or siRNA , is a piece of RNA that the cell snips from an invading virus or other threat and then uses to seek out and destroy the potentially deadly intruder. (nih.gov)
  • Here we report a class of mRNA granules in human neuronal processes that are enriched in the nuclear cap-binding protein complex (CBC) and exon junction complex (EJC) core components, Y14 and eIF4AIII. (frontiersin.org)
  • TDP-43 pathology includes cytoplasmic aggregates of the normally nuclear protein. (alzforum.org)
  • The interaction is most likely an early event" in disease, Ling speculated, leading up to later stages where TDP-43 and FUS, normally nuclear proteins, are mislocalized and aggregated in the cytoplasm. (alzforum.org)
  • Because of this, microRNAs are not part of the "coding genome," but constitute what some people call the epigenome. (sciencedaily.com)
  • ing of microRNAs to the genome or inside the cel via membrane-to-nu- 2011 ). (who.int)
  • Right here, KSRP binds towards the terminal loop of the mark miRNA precursors and thus promotes their maturation. (iassist2012.org)
  • A team led by Dr. Sean Morrison, Director of CRI, Professor of Pediatrics and the Mary McDermott Cook Chair in Pediatric Genetics at UT Southwestern Medical Center, has identified an RNA-binding protein called IMP1 that promotes stem cell self-renewal during fetal development. (utsw.edu)
  • At the same time, researchers including Dr. Hao Zhu, who also directs a lab at CRI and is Assistant Professor of Pediatrics and Internal Medicine at UT Southwestern, have shown that another RNA-binding protein, Lin28a, also promotes tissue repair by reactivating a metabolic state reminiscent of the juvenile developmental stage.

  • Structural insights into RNA quality control: the Ro autoantigen binds misfolded RNAs via its central cavity. (albany.edu)
  • Cognition through the (st-)ages: consequences of immuno-toxic lesions, protein accumulation and environmental stressors. (uni-muenchen.de)
  • The microRNA plays a similar role during tumorigenesis, protecting breast cancer stem cells from the effects of interferons secreted by immune cells present in the tumor. (medicalxpress.com)
  • Overexpressing RBM3 protein causes a normal cell to become transformed into a cancer cell. (grantome.com)
  • Scientists are also harnessing RNA as a research tool and as the basis for new therapies for infections, cancer and other conditions. (nih.gov)
  • Based on our identified miRNA-regulated network, we discovered three drugsBX-912, daunorubicin, and midostaurinthat can be repositioned to treat lung cancer, which was not known before. (cdc.gov)
  • Based on our identified miRNA-regulated molecular machinery, an inhibitor of PDK1/Akt BX-912, an anthracycline antibiotic daunorubicin, and a multi-targeted protein kinase inhibitor midostaurin were discovered as potential repositioning drugs for treating lung cancer. (cdc.gov)
  • One important heat shock protein is discussed further in the blog entry HSP70 to the rescue The relatively recent blog entries Mitohormesis and Radiation hormesis define hormesis in more detail and discuss it as it relates to mitochondrial oxidative stress and stress induced by radiation. (anti-agingfirewalls.com)
  • Our preliminary results suggest that PICK1 anchors Argonaute2 to membrane-bound structures inside the neuron called endosomes, which are involved in trafficking important receptors to the synapse during synaptic plasticity. (ukri.org)
  • Our studies also suggest that RBM3 is regulated at the posttranslational levels of phosphorylation, ubiquitination and SUMOylation. (grantome.com)
  • The plant hormone indole-3-acetic acid (IAA), commonly referred to as auxin, plays a major role in regulating plant growth and development. (sciencedaily.com)
  • To find clues to the protein's normal role, the scientists isolated the wild-type protein, with its associated hangers-on, and used mass spectrometry to identify the partners. (alzforum.org)
  • Also, the role of microRNAs in the tumorigenesis will be determined. (grantome.com)
  • In conclusion, the reduction in IAV copy number in DEFB1 overexpressing cells suggests that beta-defensin-1 plays a key role in regulating IAV survival through STAT3 and is a potential target for antiviral drug development. (cdc.gov)
