Disease relevance of POLY U

 

High impact information on POLY U

  • Among the homopolymers of the four common ribonucleotides, activated ribonuclease L degrades at an appreciable rate only polyuridylic acid [5].
  • Differential effects of polyadenylic: polyuridylic acid and lipopolysaccharide on the generation of cytotoxic T lymphocytes [6].
  • The WBC-associated RNase activity directed against polyuridylic acid decreased with the progression of neoplastic disease, though serum RNase activity remained unchanged [7].
  • Double-stranded RNA's, such as the copolymers of polyinosinic and polycytidylic acids and polyadenylic and polyuridylic acids, could not alone induce differentiation of the cells, but enhanced induction of differentiation by low concentrations of the D-factor and induced a significant amount of interferon [8].
  • Among other tested RNAs, only polyuridylic acid induced IL-12 p70 [9].
 

Chemical compound and disease context of POLY U

 

Biological context of POLY U

 

Anatomical context of POLY U

  • In pilot studies without tRNA, the binding constant of the initiation triplet codon adenylyl-(3' leads to 5')-uridylyl-(3' leads to 5')-guanosine to 70 S ribosome was found to be an order of magnitude larger than that of polyuridylic acid [18].
  • The extracts, prepared via spheroplasts and depleted of endogenous mRNA with nuclease, translate exogenous natural mRNA and polyuridylic acid [19].
  • A solid support radioimmunoassay has been developed to detect immunoglobulin specific circulating antibodies to polyuridylic acid (Pol U), single-stranded RNA (ss RNA), and single-stranded DNA (ss DNA) in scleroderma and other connective tissue diseases [20].
  • Polyadenylic polyuridylic acid and beryllium sulfate produced an increase in the number of lymphocytes in the T cell zones by 12 to 24 hours, but mitotic activity was unremarkable [21].
  • In contrast, supernatant fractions from the deficient spleens had a reduced ability to incorporate labeled amino acids into protein, both in the presence of endogenous mRNA and in the presence of added polyuridylic acid [22].
