Disease relevance of SNORD25

  • Metal ion-induced changes in HIV-1 TAR RNA internal dynamics were determined by the changes in EPR spectral width for TAR RNAs containing spin-labeled nucleotides (U23, U25, U38, and U40) [1].
  • The cytotoxicity was measured in MTT tests using the cisplatin resistant human U25 1 malignant glioma cell line as a model [2].
 

High impact information on SNORD25

  • Depletion of U25 from the Xenopus oocyte abolished 2'-O-methylation of G1448 in 18S rRNA; methylation could be restored by injecting either the Xenopus or human U25 transcript into U25-depleted oocytes [3].
  • TAR RNAs containing single nitroxide spin-labels in the 2'-position of U23, U25, U38, or U40 were incubated with compounds known to inhibit TAR-Tat complex formation [4].
  • Mg(2+), Co(2+), Ni(2+), Zn(2+), and Ba(2+) had similar effects on U23, U38, and U40, but the mobility of U25 was markedly increased [1].
  • While Li(+) and K(+) had little effect on TAR RNA internal dynamics, Na(+) unexpectedly had a dynamic signature that was similar to Ca(2+) and Sr(2+), with a decrease in mobility at U23 and U38, little or no change at U25, and an increase in mobility at U40 [1].
  • DNA binding, cellular penetration, and cytotoxicity were compared in three human glioma cell lines (T98G, U87-MG, and U25 IN) and a human fibroblast cell strain (HS 68) [5].
