These operons also share components with the Pgl system of reverse restriction-modification that encompasses many genes whose functions remain unclear although some of these encode domains suggestive of toxin-like activities [ 6] (VA, L.M. Iyer, LA, unpublished).
Novartis is arguing that the term should encompass modifications that might make a drug safer or easier to use, not just more effective in treating a disease.
Global disruption of the epigenetic code is a hallmark of malignancy that encompasses many distinct modifications that are highly interactive.
Such epigenetic signatures encompass the heritable modifications that do not change the DNA sequence but rather provide 'extra' layers of control that regulate chromatin organization and gene expression [30], [31].
In contrast, "hard" transformations are those inducing dramatic structural modifications that extend beyond localized moieties to encompass changes across the molecule's entirety (e.g., ring cleavage in steroids), although several sequential reactions may be needed to attain extensive structural modification.
Class A mimetics encompass conformationally constrained peptides with moderate modifications that yield peptidomimetics with the highest degree of similarity to their respective parent peptide.
We will outline a variety of positions that encompass an ever more extensive range of modifications to the basic TOL concept.
For each core histone peak eluting from the LC, we selected a specific mass range that encompassed all of its isoforms in an unmodified state as well as the possible spectrum of modifications that could occur.
Stress response constitutes another broad category of conserved age-related pathways that encompass a variety of biological processes, from immune regulation to epigenetic modification [12], [13], [14].
Histone modifications that promote gene transcription.
Histone modifications that promote transcription elongation.
