    Tetrastable system built from two cross-inhibitory bistable switches. (a) Schematic of the tetrastable DNA circuit. Two microRNA-sensing circuits (cT, aT, pT, and rT) are interconnected by kT αkβ and βkα, which repress unwanted cross-activation. (b) Detailed mechanism of the five kinds of templates (pol. = Vent(exo-), nick. 1 = Nt.BstNBI, nick. 2 = Nb.BsmI, RE = BsmI, and exo. = ttRecJ). cTs convert the complementary microRNA target to a signal strand (α or β). Autocataytic templates (aTs) exponentially amplify the signal strands. pTs, by deactivating a fraction of signal strands, suppress background amplification stemming from biochemical noise. Reporting templates (rTs) transduce the molecular signal (α or β) to a detectable fluorescence signal (green = Oregon green fluorophore, red = Atto633 fluorophore). From the α or β strands, killer templates (kTs) produce pTs of the opposite switch, mitigating unspecific cross-talks. All produced strands are continuously degraded by the exonuclease to maintain the system dynamics and avoid system poisoning by the accumulation of DNA strands. Only one half of the tetrastable circuit is represented here, the second half being obtained by substituting α by β and conversely.

    Schematic representation of PADDA and identified DNA damage. ( A ) A single non-cycled primer extension performed with a 5′-biotin-tagged primer and Vent exo– DNA polymerase identifies damaged nucleotides (inverted triangles), and generates a pool of highly specific biotin-tagged extended products (EP), each of them derived from a single DNA molecule and strand. Each extended product has a stop (indicated by a red star), which represents replicative arrest by a damaged nucleotide, a nick or random polymerase stalling. Some extended products will contain misincorporations (indicated by a solid red circle) that represent polymerase lesion by-pass with misincorporation. After several purification steps that include the use of biotin-binding, streptavidin-coated, paramagnetic beads, the strand-specific, highly purified, biotin-bound extended products can be used for damage fingerprinting or quantification. ( B ) For strand specific fingerprinting analysis (f-PADDA) of damage and repair at the single-nucleotide level, the purified pool of EPs is ligated to a chemically modified oligonucleotide-adapter using a highly efficient single-strand DNA ligase. The pool of adapter-linked EPs can be diluted to one EP per well and each EP is directly amplified and sequenced, or the EPs can be amplified as a pool, cloned and sequenced. In either case high fidelity amplification is performed using an oligonucleotide complementary to the adapter–primer and a nested gene-specific primer. Data is obtained in

    Article Snippet: Vent exo–, a truncated form of a native DNA polymerase (Vent, NEB), was chosen for this assay instead of the currently used Sequenase ( ) or Taq DNA polymerase , because of its reported high sensitivity to detect DNA damage ( ) and primer-extension efficiency ( ).
