Interestingly, three (SCO0588, SCO3986, and SCO5454-SCO5455) of these four hubs encode two-component systems that regulate gene expression by sensing environmental cues.
Gigantism is caused by disease or disorder in those parts of the endocrine system that regulate growth and development.
A candidate for such local c-di-GMP signalling is provided by the system that regulates the expression of CsgD (Pesavento et al, 2008), a key biofilm regulator that activates the genes for amyloid curli fibres which accumulate in the biofilm matrix of E. coli and other enteric bacteria (Römling et al, 2000).
Since the Fe concentration in Δccc1 cells was ∼20% less than in equivalent WT cells, we further conjectured that this putative cytosolic FeII complex was sensed by the system that regulates Fe import into the cell.
Nitrogen uptake in roots is mainly regulated by a high-affinity transport system that regulates uptake at N levels <1 mM, and a low-affinity transport system that functions at higher N concentrations (Forde and Clarkson 1999; Glass et al. 2001; Williams and Miller 2001).
A system that regulates entry by reading the iris of the human eye will soon be tested in a New Jersey school system.
A parallel control strategy is developed for process applications by "reverse engineering" the functions of the baroreceptor reflex the biological control system that regulates arterial blood pressure.
In addition to the expression of TF and cancer procoagulant, tumour cells enhance coagulation in patients with cancer by expressing proteins that regulate the fibrinolytic system, including plasminogen activators, plasminogen activator inhibitors 1 and 2, and plasminogen-activator receptor, leading to an imbalance of fibrinolysis (Prandoni et al, 2005).
But today's fuel injection systems are controlled by increasingly powerful onboard computers that regulate combustion efficiency, govern fuel economy and regulate emissions to federal and state standards.
Human endocrine system, group of ductless glands that regulate body processes by secreting chemical substances called hormones.
