While none of these data prove a direct link between REST, histone deacetylases, H3K4me3, and expression, they all strongly support the model whereby the REST/HDAC complex antagonizes the H3K4me3 mark and subsequent transcription.
In particular, they indicate that the binding of ZLD to target sites across the genome prior to the MZT may trigger a cascade of events—reflected in early histone depletion, the appearance of several histone acetylation marks, and the subsequent appearance of functional class-specific methylation marks that may act to counter the establishment of Polycomb-mediated repression in many loci.
A potential explanation could be that even SAH of minor extent can cause acute vasoconstriction, marked CPP, and subsequent rCBF decline [31].
When COME cells were treated with IL-1β or EGF, early and marked increases and subsequent rapid decreases were observed for all HAS genes and, moreover, actual changes in hyaluronan synthesis subsequently occurred.
Analysis revealed a statistically significant association between the location of places in which the mice had positioned way-marks and the subsequent pattern of their movements.
By monitoring the positions and times at which these events occurred and by measuring the products' kinetic energies, the Dubna team discovered a few series of correlated events that marked the creation and subsequent disintegration of two isotopes of the new element: 293117 and 294117.
Under atrophy signal, the inhibitory protein of NF-κB, IκBα becomes phosphorylated and so is marked for ubiquitination and subsequent proteasomal degradation.
In the canonical NFκB activation pathway, upon phosphorylation by IKKβ, Iκβα and IκBβ, the cytoplasmic inhibitors of NFκB, are marked for ubiquitination and subsequent proteosomal degradation (DiDonato et al, 1996; Ghosh and Karin, 2002).
Some events such as the breakup of rpoB into two contiguous ORFs, the disruption of multiple ancestral operons and the expansion of clpP, rps3, and rps4 coincided with the appearance of the Chlorophyceae, whereas gains of numerous derived gene pairs and trans-spliced group II introns marked the emergence and subsequent divergence of the CS and OCC clades.
