Reducing AIM2 expression by shRNA in THP-1 cells decreased NFR-mediated IL-1β secretion, similar to the phenotype observed with the known AIM2 activator poly(dA:dT) ( Fig. 7 A ). The major source of the poly(dA) poly(dT) tracts in the eukaryotic genomes is poly(dA) tails of peudogenes and retroposons. In the human genome, Alu sequences appear approximately every 3 kb and 80% of them contain perfect A stretches of >10 bp ( 41). Although the biological and evolutional significance of these elements are not known, one of "Poly dA-dT" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. The reaction can be split under proper condition into two consecutive steps, the double helix formation of poly dA · poly dT and the addition of the poly U strand to form a trip · helix poly dA · poly dT · poly rU.

We propose that the evolutionary expansion of poly(dA:dT) tracts in eukaryotic genomes promotes replication initiation, but at the cost of chromosome fragility. Apr 11, 2000 · The poly(dA/dT) − clone contained only 11 dA (green) or 11 dT (red) residues, depending on the cloning orientation. Poly(dA/dT) + clones contained longer dA or dT residues. (B) Summary of the results for different anchored oligo(dT) primers and reverse transcriptases. Poly(dA:dT) sequences are fragile because long single-strand poly(dA) stretches at the replication fork are unprotected by the replication protein A (RPA).

15 Aug 2018 Poly(dA:dT) tracts characterize strong DNA replication origins in mammals and cause replication-fork collapse and DNA breaks that underlie

Working concentrations and length of treatment can vary depending on the desired effect. Jul 16, 2009 · Poly(dA:dT) has been used to study RNA polymerase III–mediated promoter-independent transcription 38,39,40.

dT)•poly(dA-dT) is evidenced by CD spectral changes at characteristic wavelengths around 295 nm and 248 nm. The drug-induced conformational transition is

The other two structures have dinucleotides as double helical repeats. Abstract. The structure of poly(dA)ṁpoly(dT) currently arouses great interest, mainly because dA n ṁdT n stretches are associated with considerable DNA bending 1,2.Until recently the heteronomous DNA described by Arnott et al. 3, with the poly(dA) and poly(dT) chains in A and B conformations respectively, was the only detailed model of this structure. Measurements of the steady‐state fluorescence spectrum and anisotropy, r, of the alternating polynucleotide poly(dA‐dT)‐poly(dA‐dT) were carried out in order to characterize its photophysical properties at room temperature.

Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. The goal for developing the SPGI (screening poly [da/dT(−)] cDNA for gene identification technique was to generate an efficient tool for maximal identification of the expressed genes from eukaryotic genomes. The impetus for developing the SPGI method was triggered by the observation that a large number of human novel transcripts have not been identified in spite of intensive efforts in the past decades using … the polynucleotides (poly(dN)), namely, (dA) 40,(dT) 40, (dG) 40 and (dC) 40, using absorption, ﬂuorescence and CD measurements, in order to understand the mode of interaction as well as to explore the possibility of DNA template directed assembly formation of TMPyP. 2.

They have unusual structural, dynamic, and mechanical properties, and may resist sharp bending. Alexeev DG, Lipanov AA, Skuratovskii IYa Poly(dA).poly(dT) is a B-type double helix with a distinctively narrow minor groove. Nature. 325 (6107):821–823.
