Taken together our results demonstrate that (i) the stabilities of BRCA1/BARD1 complexes are regulated in a mutagen-specific manner, and (ii) indicate the existence of mechanisms that may be required to prevent the simultaneous recruitment of conflicting signaling pathways to sites of DNA damage.
Although the sequential treatments showed antagonistic effects, this is not the first time a sequential treatment with an HDACI has been found to be antagonistic, which was found to be due to conflicting signalling pathways (Kuefer et al, 2007).
Substrate affinities and enzymatic rates may be enhanced by chemical modifications and cooperation with other repair factors that signal damage sites, or alternatively be repressed by competing enzymes in the case of overlapping, branching or conflicting repair pathways.
The authors found evidence for a gradual developmental progression from less serious to serious antisocial behaviours along three pathways identified as overt, covert and authority conflict pathways.
Despite the wealth of information found for pathway construction mainly from pathway databases, conflicting reports in pathway connectivity makes the construction of the generic topology a non-trivial task with significant manual curation and with no guaranteed for the "right" generic topology.
This raises fundamental challenges for planning practice, which are explored here through a discussion of situational dissensus, conflicting rationalities, and pathways for democratic institutional innovation.
Given the amount of possible challenges a plant face from their environment, plants need to activate and prioritize between potentially conflicting defense signaling pathways.
As the number of health professionals involved in the patients' care increases, patients are more likely to be faced with conflicting instructions and care pathways, and fragmented medical care, making it more challenging for them to adhere to and piece together these instructions, in turn preventing them from participating effectively in their own care [ 3, 4, 7, 9, 10].
In contrast, when using a hard core, most models included a majority of bile acid reactions (60%~80% of pathway reactions), conflicting with known tissue specificity.
These apparently conflicting data suggest that the pathways of Cd2+-induced apoptosis differ according to the cell type or the exposure (cell treatment) conditions.
