Optimal Computation of Avoided Words [PDF]

open access: yes, 2016
The deviation of the observed frequency of a word $w$ from its expected frequency in a given sequence $x$ is used to determine whether or not the word is avoided. This concept is particularly useful in DNA linguistic analysis.

Endonuclease G from mammalian nuclei is identical to the major endonuclease of mitochondria

open access: yesNucleic Acids Research, 1995
Two Mg(2+)-dependent DNA endonucleases have been isolated from mammalian cells which have a strong preference to nick within long tracts of guanine residues in vitro. One endonuclease activity is mitochondrial (mt). The other endonuclease, called Endonuclease G, is associated with isolated nuclei, and is released when the nuclear chromatin is exposed ...

Matrix metalloproteinases-2,-3,-7,-9 and-10, but not MMP-11, are differentially expressed in normal, benign tumorigenic and malignant human keratinocyte cell lines [PDF]

open access: yes, 2000
In order to investigate the correlations between constitutive proteinase expression and the degree of tumorigenicity of cancer cells we have studied a model system of three keratinocyte cell lines.

Induction of kidney endonucleases by DNase I: evidence of endonuclease network

open access: yesThe FASEB Journal, 2012
Endonuclease‐mediated DNA fragmentation is both an immediate cause and a result of apoptosis and all other types of irreversible cell death during kidney injury. It is produced by nine enzymes: DNase I and 2 families, CAD and EndoG, which act simultaneously. However, regulatory links between these enzymes have not been established. We hypothesized that

Home and away- the evolutionary dynamics of homing endonucleases

open access: yesBMC Evolutionary Biology, 2011
Background Homing endonucleases (HEases) are a large and diverse group of site-specific DNAases. They reside within self-splicing introns and inteins, and promote their horizontal dissemination.
