By incorporating these candidate endophenotypes into molecular genetic studies, both statistical power as well as insight into gene-behavior pathways may be gained.
It is quite remarkable that a network derived from behavior of pathways based on transcriptional regulation shows close interdependence between various pathways involved in nitrogen metabolism.
There is better understanding of species sensitivity to contaminants, organism behavior, exposure pathways, and design considerations necessary to provide relevant exposure conditions.
Based on the chromatographic retention behavior, fragmentation pathways of chemical components and the published literatures, a diagnostic ion filtering strategy with electrospray ionization quadrupole time-of-flight tandem mass spectrometry (HPLC-ESI-Q-TOF/MS) was established to identify the multiple bioactive constituents of GGFTT.
However, although QS is most easily interpreted as a population-counting behavior, QS pathways are typically complex, often employing multiple autoinducer signals and receptors.
By transcriptional intervention conducted in silico, dynamic behavior of pathways was examined, which demonstrate how much and in which specific ways each gene or gene combination effects the behavior transition of a pathway in response to ESC differentiation or pluripotency induction.
Mathematical modeling of dynamic behavior of pathways, followed by gene perturbation or knock-out experimentation, is promising in reprogramming stem cells for directed differentiation into specific cell types, or reprogramming somatic cells for pluripotency induction.
To further explore the mechanisms controlling ESC pluripotency, we conducted a series of transcriptional interventions in silico on every gene or gene combination to model the dynamic behavior of pathways in transitions between ESC and EB states.
Systems-based properties, such as feedback loops and functional redundancy in the structure of biological networks, have been shown to be the underlying cause for the sustained or recurrent molecular behavior of pathways in different organisms.
