  • Because the vaccines use a technology called messenger RNA, or mRNA, there's confusion and misinformation about what the vaccine does after it's injected into your arm. (ksat.com)
Translation1
  • This new study has revealed how the Inc-SMaRT can negatively regulate the translation of a messenger RNA, MLX-g, fundamental in the muscle tissue formation. (uniroma1.it)
Viruses3
Binds1
  • The fly Pcif1 expressed in the nucleus and binds the phosphorylated C-terminal domain (CTD) of RNA Pol II (at the level of phosph orylated s erine 5). (cea.fr)
Lateral1
  • The lateral nucleus of the amygdala (LA) is a critical brain region for fear learning and regulating the effects of stress on memory. (frontiersin.org)

Actively transported1
  • These large molecules must be actively transported into the nucleus instead. (wikipedia.org)
Single-strand1
  • Second, there is a chemical process to synthesize single-strand RNAs. (bartleby.com)
Nanoparticles2
  • These RNA-delivering nanoparticles successfully reduced inflammation in mice, without side effects. (world.edu)
  • Anderson and Langer, who are both members of MIT's David H. Koch Institute for Integrative Cancer Research, have developed similar nanoparticles to deliver RNA interference treatments for other diseases, including liver and ovarian cancers. (world.edu)
Nuclear4
  • and the nuclear matrix, a network within the nucleus that adds mechanical support. (wikipedia.org)
  • The nucleus contains nearly all of the cell's DNA, surrounded by a network of fibrous intermediate filaments called the nuclear matrix, and is enveloped in a double membrane called the nuclear envelope. (wikipedia.org)
  • The nuclear pore complex (NPC), which we mentioned briefly here and here , has been a prime target of research for years now, ever since biochemists realized how large it is and the vital role it plays guarding what moves in and out of the nucleus. (evolutionnews.org)
  • It is surrounded by a membrane called the nuclear envelope, which contains holes, the nuclear pores, through which traffic into and out of the nucleus takes place. (cosmeticsdesign.com)
Moderna1
  • Two vaccines, one by Pfizer and one by Moderna, use messenger RNA (mRNA) technology . (seiu.org)
Hypothesis2
  • The unique potential of RNA molecules to act both as an information carrier and as catalyst forms the basis of the RNA world hypothesis. (bartleby.com)
  • SIGNIFICANCE STATEMENT A major hypothesis posits neuronal inhibitions in nucleus accumbens generate intense motivation. (jneurosci.org)
19981
  • Since RNA interference was discovered in 1998, its ability to potentially shut off any gene in the body has intrigued scientists. (world.edu)
Hypothalamus2
  • In the present study, we found that forced swimming differentially influenced the expression of messenger RNA for vasopressin, oxytocin and corticotrophin-releasing hormone (CRH) in the paraventricular nucleus of the hypothalamus (PVN) in the prairie vole brain. (okstate.edu)
  • In situ hybridization analysis of apelin receptor mRNA expression in the adult rat brain showed intense labeling in the hypothalamus, especially in the supraoptic and the paraventricular nuclei. (nih.gov)
Stability1
  • These posttranscriptional steps, along with changes in RNA stability, have received considerable attention for two reasons. (dekooktips.com)
Humans1
  • Insights from the present study could accelerate the efforts of biotech companies that seek to harness this natural RNA editing process in humans for therapeutic benefit. (scitechdaily.com)
COVID2
  • No, the COVID vaccines made with messenger RNA do not interact with your DNA at all. (healthychildren.org)

Instructions1
  • Revealing yet another super-power in the skillful squid, scientists have discovered that squid massively edits their own genetic instructions not only within the nucleus of their neurons, but also within the axon - the long, slender neural projections that transmit electrical impulses to other neurons.
