Nature Communications, 2016 Cytosine mutations within TCA/T motifs are common in cancer. A likely cause is the DNA cytosine deaminase APOBEC3B (A3B). However, A3B-null breast tumours still have this mutational bias.

Electrons in Dry DNA from Density Functional Calculations
, 2002 The electronic structure of an infinite poly-guanine - poly-cytosine DNA molecule in its dry A-helix structure is studied by means of density-functional calculations. An extensive study of 30 nucleic base pairs is performed to validate the method.

Expression systems for industrial Gram-positive bacteria with low guanine and cytosine content [PDF]
, 1997 Recent years have seen an increase in the development of gene expression systems for industrial Gram-positive bacteria with low guanine and cytosine content that belong to the genera Bacillus, Clostridium, Lactococcus, Lactobacillus, Staphylococcus and ...

Advanced Healthcare Materials, EarlyView.Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

Recurrent acquisition of cytosine methyltransferases into eukaryotic retrotransposons
Nature Communications, 2018 Transposable elements are in a constant arms race with the silencing mechanisms of their host genomes. One silencing mechanism commonly used by many eukaryotes is dependent on cytosine methylation, a covalent modification of DNA deposited by C5 cytosine ...

Genetic variations in the human cannabinoid receptor gene are associated with happiness.
PLoS ONE, 2014 Happiness has been viewed as a temporary emotional state (e.g., pleasure) and a relatively stable state of being happy (subjective happiness level).

The methylation landscape of giga-genome and the epigenetic timer of age in Chinese pine
Nature Communications, 2023 DNA methylation level declines during aging of mammals. Here, the authors report single-base resolution landscape of cytosine DNA methylation at different ages of Chinese pine and show that the global cytosine DNA methylation gradually increases as age ...
