DNA demethylation by DNA repair [PDF]
Trends in Genetics, 2009 Active DNA demethylation underlies key facets of reproduction in flowering plants and mammals and serves a general genome housekeeping function in plants. A family of 5-methylcytosine DNA glycosylases catalyzes plant demethylation via the well-known DNA base-excision-repair process.

The DNA damage response acts as a safeguardagainst harmful DNA–RNA hybrids ofdifferent origins [PDF]
, 2019 Despite playing physiological roles in specific situations, DNA–RNA hybrids threat genome integrity. To investigate how cells do counteract spontaneous DNA–RNA hybrids, here we screen an siRNA library covering 240 human DNA damage response (DDR) genes ...

High cell-surface density of HER2 deforms cell membranes
Nature Communications, 2016 HER2 is frequently overexpressed in breast cancer in association with increased metastatic potential. Here, the authors show that HER2 overexpression causes deformation of cell membranes in a signalling-independent manner that contributes to the disease ...

A rapid alkaline extraction procedure for screening recombinant plasmid DNA.
Nucleic Acids Research, 1979 A procedure for extracting plasmid DNA from bacterial cells is described. The method is simple enough to permit the analysis by gel electrophoresis of 100 or more clones per day yet yields plasmid DNA which is pure enough to be digestible by restriction ...

Tumor suppressor p53 binds with high affinity to CTG-CAG trinucleotide repeats and induces topological alterations in mismatched duplexes [PDF]
, 2005 DNA binding is central to the ability of p53 to function as a tumor suppressor. In line with the remarkable functional versatility of p53, which can act on DNA as a transcription, repair, recombination, replication, and chromatin accessibility factor ...

Elongation/Compaction of Giant DNA Caused by Depletion Interaction with a Flexible Polymer [PDF]
, 2005 Structural changes in giant DNA induced by the addition of the flexible polymer PEG were examined by the method of single-DNA observation. In dilute DNA conditions, individual DNA assumes a compact state via a discrete coil-globule transition, whereas in concentrated solution, DNA molecules exhibit an extended conformation via macroscopic phase ...

16S ribosomal DNA amplification for phylogenetic study
Journal of Bacteriology, 1991 A set of oligonucleotide primers capable of initiating enzymatic amplification (polymerase chain reaction) on a phylogenetically and taxonomically wide range of bacteria is described along with methods for their use and examples.

Quantitative mechanisms of DNA damage sensing and signaling
, 2020 DNA damage occurs abundantly during normal cellular proliferation. This necessitates that cellular DNA damage response and checkpoint pathways monitor the cellular DNA damage load and that DNA damage signaling is quantitative.

DNA glycosylases: in DNA repair and beyond [PDF]
Chromosoma, 2011 The base excision repair machinery protects DNA in cells from the damaging effects of oxidation, alkylation, and deamination; it is specialized to fix single-base damage in the form of small chemical modifications. Base modifications can be mutagenic and/or cytotoxic, depending on how they interfere with the template function of the DNA during ...
