Redmond Red, a fluoropore containing a redox-active phenoxazine core, has been explored as a new electrochemical probe for the detection of abasic sites in double-stranded DNA. The electrochemical behavior of Redmond Red-modified DNA at gold surfaces exhibits stable, quasi-reversible voltammetry with a midpoint potential centered around -50 mV versus NHE. Importantly, with Redmond Red positioned opposite an abasic site within the DNA duplex, the electrochemical response is significantly enhanced ...[more]

Project description:[Ru(bpy)2(BNIQ)]2+ (BNIQ = Benzo[c][1,7]naphthyridine-1-isoquinoline), which incorporates the sterically expansive BNIQ ligand, is a highly selective luminescent probe for DNA mismatches and abasic sites, possessing a 500-fold higher binding affinity toward these destabilized regions relative to well-matched base pairs. As a result of this higher binding affinity, the complex exhibits an enhanced steady-state emission in the presence of DNA duplexes containing a single base mismatch or abasic site compared to fully well-matched DNA. Luminescence quenching experiments with Cu(phen)22+ and [Fe(CN)6]3- implicate binding of the complex to a mismatch from the minor groove via metalloinsertion. The emission response of the complex to different single base mismatches, binding preferentially to the more destabilized mismatches, is also consistent with binding by metalloinsertion. This work shows that high selectivity toward destabilized regions in duplex DNA can be achieved through the rational design of a complex with a sterically expansive aromatic ligand.

Project description:Base excision repair (BER) plays a vital role in maintaining genomic integrity in mammalian cells. DNA polymerase λ (Pol λ) is believed to play a backup role to DNA polymerase β (Pol β) in base excision repair. Two oxidized abasic lesions that are produced by a variety of DNA-damaging agents, including several antitumor antibiotics, the C4'-oxidized abasic site following Ape1 incision (pC4-AP), and 5'-(2-phosphoryl-1,4-dioxobutane) (DOB), irreversibly inactivate Pol β and Pol λ. The interactions of DOB and pC4-AP with Pol λ are examined in detail using DNA substrates containing these lesions at defined sites. Single-turnover kinetic experiments show that Pol λ excises DOB almost 13 times more slowly than a 5'-phosphorylated 2-deoxyribose (dRP). pC4-AP is excised approximately twice as fast as DOB. The absolute rate constants are considerably slower than those reported for Pol β for the respective reactions, suggesting that Pol λ may be an inefficient backup in BER. DOB inactivates Pol λ approximately 3-fold less efficiently than it does Pol β, and the difference can be attributed to a higher K(I) (33 ± 7 nM). Inactivation of Pol λ's lyase activity by DOB also prevents the enzyme from conducting polymerization following preincubation of the protein and DNA. Mass spectral analysis of GluC-digested Pol λ inactivated by DOB shows that Lys324 is modified. There is inferential support for the idea that Lys312 may also be modified. Both residues are within the Pol λ lyase active site. When acting on pC4-AP, Pol λ achieves approximately four turnovers on average before being inactivated. Lyase inactivation by pC4-AP is also accompanied by loss of polymerase activity, and mass spectrometry indicates that Lys312 and Lys324 are modified by the lesion. The ability of DOB and pC4-AP to inactivate Pol λ provides additional evidence that these lesions are significant sources of the cytotoxicity of DNA-damaging agents that produce them.

Project description:DNA abasic (AP) sites are one of the most frequent lesions in the genome and have a high mutagenic potential if unrepaired. After selective attachment of 2-aminomethyl-18-crown-6 (18c6), individual AP lesions are detected during electrophoretic translocation through the bacterial protein ion channel ?-hemolysin (?-HL) embedded in a lipid bilayer. Interactions between 18c6 and Na(+) produce characteristic pulse-like current amplitude signatures that allow the identification of individual AP sites in single molecules of homopolymeric or heteropolymeric DNA sequences. The bulky 18c6-cation complexes also dramatically slow the DNA motion to more easily recordable levels. Further, the behaviors of the AP-18c6 adduct are different with respect to the directionalities of DNA entering the protein channel, and they can be precisely manipulated by altering the cation (Li(+), Na(+) or K(+)) of the electrolyte. This method permits detection of multiple AP lesions per strand, which is unprecedented in other work. Additionally, insights into the thermodynamics and kinetics of 18c6-cation interactions at a single-molecule level are provided by the nanopore measurement.

Project description:Oxidative damage to DNA has been linked to aging, cancer, and other biological processes. Reactive oxygen species and various antitumor agents including bleomycin and ionizing radiation have been shown to cause oxidative DNA sugar damage. Detection of DNA lesions is important for understanding the toxicological or therapeutic consequences associated with such agents. C4'-oxidized abasic sites (C4-AP) are produced by the antitumor drug bleomycin and ionizing radiation. The currently available methods for the detection of C4-AP cannot provide both structural and sequence information. We have developed an LC-ESI-MS-based approach for specific detection and mapping of C4-AP from a mixture of lesions. We show using Fe-bleomycin-damaged DNA that C4-AP can be detected at cytosine and thymine sites by direct MS analysis. Our results reveal that collision-induced dissociation of C4-AP-containing oligonucleotides results in preferential fragmentation at C4-AP sites with the formation of the unique a* ions (18 amu more than the a-B ions) that allow mapping of the C4-AP sites. Various chemical modification strategies (e.g., reduction with NaBH4 and NaBD4 and derivatization with methoxyamine and hydrazine, followed by LC-MS analysis) were also used for unambiguous detection of C4-AP sites. Finally, we show that the methods described here can detect the presence of C4-AP at specific sites in a complex sample such as hydroxyl radical-damaged DNA. The LC-MS approach was also used for the simultaneous detection of the other C4'-oxidation end product, 3'-phosphoglycolate, at a specific site in hydroxyl radical-damaged DNA. Thus, LC-MS provides a rapid and direct approach for the detection and mapping of oxidative DNA lesions.

Project description:Modifications and loss of bases are frequent types of DNA lesions, often handled by the base excision repair (BER) pathway. BER is initiated by DNA glycosylases, generating abasic (AP) sites that are subsequently cleaved by AP endonucleases, which further pass on nicked DNA to downstream DNA polymerases and ligases. The coordinated handover of cytotoxic intermediates between different BER enzymes is most likely facilitated by the DNA conformation. Here, we present the atomic structure of Schizosaccharomyces pombe Mag2 in complex with DNA to reveal an unexpected structural basis for nonenzymatic AP site recognition with an unflipped AP site. Two surface-exposed loops intercalate and widen the DNA minor groove to generate a DNA conformation previously only found in the mismatch repair MutS-DNA complex. Consequently, the molecular role of Mag2 appears to be AP site recognition and protection, while possibly facilitating damage signaling by structurally sculpting the DNA substrate.

Project description:In DNA, the loss of a nucleobase by hydrolysis generates an abasic site. Formed as a result of DNA damage, as well as a key intermediate during the base excision repair pathway, abasic sites are frequent DNA lesions that can lead to mutations and strand breaks. Here we present snAP-seq, a chemical approach that selectively exploits the reactive aldehyde moiety at abasic sites to reveal their location within DNA at single-nucleotide resolution. Importantly, the approach resolves abasic sites from other aldehyde functionalities known to exist in genomic DNA. snAP-seq was validated on synthetic DNA and then applied to two separate genomes. We studied the distribution of thymine modifications in the Leishmania major genome by enzymatically converting these modifications into abasic sites followed by abasic site mapping. We also applied snAP-seq directly to HeLa DNA to provide a map of endogenous abasic sites in the human genome.

Project description:Studies of replicative DNA polymerases have led to the generalization that abasic sites are strong blocks to DNA replication. Here we show that yeast replicative DNA polymerase epsilon bypasses a model abasic site with comparable efficiency to Pol eta and Dpo4, two translesion polymerases. DNA polymerase epsilon also exhibited high bypass efficiency with a natural abasic site on the template. Translesion synthesis primarily resulted in deletions. In cases where only a single nucleotide was inserted, dATP was the preferred nucleotide opposite the natural abasic site. In contrast to translesion polymerases, DNA polymerase epsilon with 3'-5' proofreading exonuclease activity bypasses only the model abasic site during processive synthesis and cannot reinitiate DNA synthesis. This characteristic may allow other pathways to rescue leading strand synthesis when stalled at an abasic site.

Project description:Nicking of the DNA strand immediately upstream of an internal abasic (AP) site produces 5'-terminal abasic (dRp) DNA. Both the intact and the nicked abasic species are reactive intermediates along the DNA base excision repair (BER) pathway and can be derailed by side reactions. Aberrant accumulation of the 5'-terminal abasic intermediate has been proposed to lead to cell death, so we explored its reactivity and compared it to the reactivity of the better-characterized internal abasic intermediate. We find that the 5'-terminal abasic group cross-links with the exocyclic amine of a nucleotide on the opposing strand to form an interstrand DNA-DNA cross-link (ICL). This cross-linking reaction has the same kinetic constants and follows the same pH dependence as the corresponding cross-linking reaction of intact abasic DNA, despite the changes in charge and flexibility engendered by the nick. However, the ICL that traps nicked abasic DNA has a shorter lifetime at physiological pH than the otherwise analogous ICL of intact abasic DNA due to the reversibility of the cross-linking reaction coupled with faster breakdown of the 5'-terminal abasic species via ?-elimination. Unlike internal abasic DNA, 5'-terminal abasic DNA can also react with exocyclic amines of unpaired nucleotides at the 3'-end of the nick, thereby bridging the nick by connecting DNA strands of the same orientation. The discovery and characterization of cross-links between 5'-terminal abasic sites and exocyclic amines of both opposing and adjacent nucleotides add to our knowledge of DNA damage with the potential to disrupt DNA transactions.

Project description:In higher eukaryotic cells, mitochondria are essential subcellular organelles for energy production, cell signaling, and the biosynthesis of biomolecules. The mitochondrial DNA (mtDNA) genome is indispensable for mitochondrial function because it encodes protein subunits of the electron transport chain and a full set of transfer and ribosomal RNAs. MtDNA degradation has emerged as an essential quality control measure to maintain mtDNA and to cope with mtDNA damage resulting from endogenous and environmental factors. Among all types of DNA damage known, abasic (AP) sites, sourced from base excision repair and spontaneous base loss, are the most abundant endogenous DNA lesions in cells. In mitochondria, AP sites trigger rapid DNA loss; however, the mechanism and molecular factors involved in the process remain elusive. Herein, we demonstrate that the stability of AP sites is reduced dramatically upon binding to a major mtDNA packaging protein, mitochondrial transcription factor A (TFAM). The half-life of AP lesions within TFAM-DNA complexes is 2 to 3 orders of magnitude shorter than that in free DNA, depending on their position. The TFAM-catalyzed AP-DNA destabilization occurs with nonspecific DNA or mitochondrial light-strand promoter sequence, yielding DNA single-strand breaks and DNA-TFAM cross-links. TFAM-DNA cross-link intermediates prior to the strand scission were also observed upon treating AP-DNA with mitochondrial extracts of human cells. In situ trapping of the reaction intermediates (DNA-TFAM cross-links) revealed that the reaction proceeds via Schiff base chemistry facilitated by lysine residues. Collectively, our data suggest a novel role of TFAM in facilitating the turnover of abasic DNA.

Project description:DNA damage can take many forms such as double-strand breaks and/or the formation of abasic (apurinic/apyrimidinic; AP) sites. The presence of AP sites can be used to determine therapeutic efficacy of many drugs, such as doxorubicin. While there are different assays to search for DNA damage, they are fraught with limitations, such as the need for large amounts of DNA secured from millions of cells. This is challenging due to the growing importance of using liquid biopsies as a source of biomarkers for many in vitro diagnostic assays. To accommodate the mass limits imposed by the use of liquid biopsies, we report a single-molecule DNA damage assay that uses plastic nanofluidic chips to stretch DNA to near its full contour length when the channel dimensions (width and depth) are near the persistence length (∼50 nm) of double-stranded (ds) DNA. The nanofluidic chip consisted of input funnels for high loading efficiency of single DNA molecules, entropic traps to store the DNA and simultaneously load a series of nanochannels for high throughput processing, and an array of stretching nanochannels to read the AP sites. Single dsDNA molecules, which were labeled with an intercalating dye and a biotinylated aldehyde reactive probe (bARP), could be parked in the stretching nanochannels, where the AP sites were read directly using a dual-color fluorescence microscope equipped with an EMCCD camera. One color of the microscope was used to read the DNA length and the second color detected the AP sites. The nanofluidic chip was made from thermoplastics via nanoimprint lithography, which obviated the need for direct writing the devices in glass or quartz using focused ion beam milling. We show that we can read the frequency of AP sites in single dsDNA molecules with the frequency of AP sites determined by associating fluorescently-labeled streptavidin with bARP through a biotin/streptavidin complex.
