Our striking finding that all the subunits of the V-ATPase localized to the DRM fraction and that treatment of cells with U18666A, which affects late endosomal cholesterol levels, lead to an increase in V1-V0 associatogethergether point to a role of the membrane composition in controlling the rate of V1-V0 association-dissociation.
Therefore, the data we report here can hardly be reconciled with a vision whereby BGC alone drives GC content evolution; rather, these finding might be consistent with a role of both base composition and intron size in gene regulation mediated by nucleosome positioning or chromatin conformation, as previously proposed [ 18, 23].
(2016) construct an augmented matching model to assess the relative role of composition effects, duration dependence, and transitions into nonparticipation in the buildup of LTU and the outward shift of the Beveridge curve in the US.

In this way the process of environment design takes on the role of composition, with sections of virtual hills, canyons and valleys acting as musical pathways through the environment.
The overall objective of this study was to investigate the role of composition, structure, and the dynamic response to load in predicting tendon mechanical properties in a multi-level fashion mimicking native hierarchical collagen structure.
The role of composition on toxic effects has been explored during the last decade by different authors.
To better understand the role of composition, several recent multicity studies have examined whether variability in proportions of PM constituents across U.S. cities can explain the observed variations in relative risks (RRs) of PM and mortality or morbidity outcomes.
Evidence of an upregulation in plant-type chitinase activity in mature A. fumigatus biofilms is emerging suggestive of a role in the composition of the extracellular matrix potentially through the liberation of extracellular DNA [18].
The toxicologic findings correlated with PM OC and polycyclic aromatic hydrocarbon (PAH) composition, suggesting a role of organic agents in generating redox activity (Table 1).
