Mechanisms of PARP inhibitor resistance in cancer and insights into the DNA damage response
Genome Medicine, 2018 Editorial summary Inhibitors of poly(ADP-ribose) polymerase (PARPi) have entered the clinic for the treatment of patients with cancers that lack homology-directed DNA repair, but drug resistance remains a clinical hurdle.

The ability to form homodimers is essential for RDM1 to function in RNA-directed DNA methylation. [PDF]
PLoS ONE, 2014 RDM1 (RNA-DIRECTED DNA METHYLATION1) is a small plant-specific protein required for RNA-directed DNA methylation (RdDM). RDM1 interacts with RNA polymerase II (Pol II), ARGONAUTE4 (AGO4), and the de novo DNA methyltransferase DOMAINS REARRANGED ...

HIV-1 reverse transcriptase mutations that confer decreased in vitro susceptibility to anti-RT DNA aptamer RT1t49 confer cross resistance to other anti-RT aptamers but not to standard RT inhibitors [PDF]
, 2005 RNA and DNA aptamers specific for HIV-1 reverse transcriptase (RT) can inhibit reverse transcription in vitro. RNA aptamers have been shown to potently block HIV-1 replication in culture.

Amplification of 4–9-kb Human Genomic DNA Flanking a Known Site Using a Panhandle PCR Variant
BioTechniques, 1997 We present a method for the in vitro amplification of >6.0 kb of DNA flanking a known site. This is accomplished by ligating an oligonucleotide to create an inverted repeat of a portion of the known sequence, followed by single-primer polymerase chain ...

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

alpha-helix E of Spo0A is required for sigma(A)- but not for sigma(H)-dependent promoter activation in Bacillus subtilis [PDF]
, 2004 At the onset of endospore formation in Bacillus subtilis, the DNA binding protein Spo0A activates transcription from two types of promoters. The first type includes the spoIIG and spoIIE promoters, which are used by sigma(A)-RNA polymerase, whereas the ...

DNA-Directed Polymerase Subunits Play a Vital Role in Human Telomeric Overhang Processing [PDF]
Molecular Cancer Research, 2015 Abstract Telomeres consist of TTAGGG repeats bound by the shelterin complex and end with a 3′ overhang. In humans, telomeres shorten at each cell division, unless telomerase (TERT) is expressed and able to add telomeric repeats.

Chimerization of antibodies by isolation of rearranged genomic variable regions by the polymerase chain reaction [PDF]
, 1991 We describe a new method for amplification, by polymerase chain reaction (PCR), of rearranged segments encoding the variable part of light and heavy chains of an antibody (Ab) from the chromosomal DNA of hybridoma cells for the chimerization ofAbs.

RanBP2-Mediated SUMOylation Promotes Human DNA Polymerase Lambda Nuclear Localization and DNA Repair [PDF]
, 2020 Cellular DNA is under constant attack by a wide variety of agents, both endogenous and exogenous. To counteract DNA damage, human cells have a large collection of DNA repair factors. Among them, DNA polymerase lambda (Polλ) stands out for its versatility,
