Stimuli responsive modification of the macrocycle can also drive such shuttling processes.
Here, we demonstrate that SUMO-2 modification of HTT, a stress-responsive modification pathway not previously investigated for HTT, regulates the accumulation of insoluble mutant HTT.
Second, we expanded the clinical outcomes of the review to include important cardio-metabolic health outcomes and obesity-related biomarkers shown to be responsive to modifications in nutritional intake and exercise in earlier studies.
Here, we report our findings from a large-scale screen for DNA-damage-responsive histone modifications in human cells.
Collectively, these data establish that multiple types of histone PTMs are involved in the DDR and, moreover, raise the prospect that additional DDR-responsive chromatin modifications await identification.
One of the well-characterized DNA-damage-responsive chromatin modification events is the phosphorylation of the C-terminal tail of histone H2A or the H2AX variant in higher eukaryotes [17].
Stimuli-responsive polymer modification of surfaces can lead to control over wettability, adhesive ability, porosity, patterning, and interfacial interactions; this topic has been reviewed elsewhere.
Taken together, these findings led us to conclude that, like the other H3 phosphorylations studied, H3T11p is not an early DNA-damage-responsive histone modification in our system, which is in contrast to the conclusions presented in a recent report (Shimada et al, 2008).
Dispersions of Carbon Black, a colloidal particle of much larger diameter, characterized as a reference system, showed a different nanomorphology and were not responsive to pH modifications, due to a different dispersion mechanism.
The results obtained suggest that despite the extensive reprogramming of donor cells that occurred by the blastocyst stage, SCNT-specific errors are of a non-random nature in bovine and are not responsive to epigenetic modifications by TSA.
Perhaps components of the origin of replication complex or other replication-associated factors are responsive to the modification state of H3K4.
