Carbethoxylation of Polynucleotides [PDF]

open access: yesEuropean Journal of Biochemistry, 1971
Diethyl pyrocarbonate has been shown to react with poly(A), poly(C) and poly(G) but poly(U) does not react. Diethyl pyrocarbonate appears to carbethoxylate amino groups on the bases. Poly(A) can bind one carbethoxy group per base but the binding capacity of poly(G) and poly(C) under non‐denaturing conditions is 0.32 and 0.23, respectively.

Synthesis, Cyclopolymerization and Cyclo-Copolymerization of 9-(2-Diallylaminoethyl)adenine and Its Hydrochloride Salt

open access: yesMolecules, 2012
We report herein the synthesis and characterization of 9-(2-diallylaminoethyl) adenine. We evaluated two different synthetic routes starting with adenine where the optimal route was achieved through coupling of 9-(2-chloroethyl)adenine with diallylamine.

DNA 3 '-Phosphatase Activity Is Critical for Rapid Global Rates of Single-Strand Break Repair following Oxidative Stress [PDF]

open access: yes, 2009
Oxidative stress is a major source of chromosome single-strand breaks (SSBs), and the repair of these lesions is retarded in neurodegenerative disease. The rate of the repair of oxidative SSBs is accelerated by XRCC1, a scaffold protein that is essential

Micro-RNAs of the miR-15 family modulate cardiomyocyte survival and cardiac repair [PDF]

open access: yes, 2015
A family of microRNAs, called the miR-15 family, which includes miR-195, are shown to be up-regulated during pathological cardiac remodeling and repress the expression of mRNAs required for cell proliferation and survival, with consequent loss of ...

BLM–DNA2–RPA–MRN and EXO1–BLM–RPA–MRN constitute two DNA end resection machineries for human DNA break repair [PDF]

open access: yes, 2011
Repair of dsDNA breaks requires processing to produce 3′-terminated ssDNA. We biochemically reconstituted DNA end resection using purified human proteins: Bloom helicase (BLM); DNA2 helicase/nuclease; Exonuclease 1 (EXO1); the complex comprising MRE11 ...

Pulling hairpinned polynucleotide chains: Does base-pair stacking interaction matter?

open access: yes, 2001
Force-induced structural transitions both in relatively random and in designed single-stranded DNA (ssDNA) chains are studied theoretically. At high salt conditions, ssDNA forms compacted hairpin patterns stabilized by base-pairing and base-pair stacking
