To investigate the potential antagonistic factors against ZS1, supernatant extract derived from CT10 culture was subjected to GC-MS analysis (see "Materials and methods").
Alternative splicing outcomes are the result of combinatorial regulation of exon recognition by multiple, sometimes antagonistic, factors that may vary between tissues and developmental stages.
Based on these observations, we argue that woc and HP1c can act as antagonistic factors regulating transcription, leading to a simple way of regulating HP1c levels within a cell by a negative feedback loop (Figure 3F).
Ang-1 and -2 are reciprocally antagonistic factors involved in important intracellular pathways.
Several mutually agonistic and antagonistic factors may be operating in these complex systems.
Inducing the innate immune cells to produce antagonistic factors to block the function of those antiviral cytokines demonstrates another strategy by which EBV eludes the immune responses.
However, a second possibility is that plasmids such as RP4 carry interbacterial antagonistic factors that provide fitness to their hosts under certain conditions.
Bioinformatics studies indicate that antagonistic factors often bind to overlapping sites [ 21] whereas synergetic factors are often positioned within a fixed distance [ 20], often close to the multiple of 10.2 bp, the DNA double-helix pitch value [ 21].
FUL, IND, ALC, SHP1/2 appear to be expressed together in the en b layer, although the nature of the interaction of these antagonistic factors is unclear and their precise role in en b development has remained elusive [ 16, 17].
Most obese individuals are, in fact, resistant to the action of leptin, possibly because of circulating antagonistic factors or a decrease in transport across the blood-brain barrier; typically, circulating leptin levels are increased in obesity.
