Preferential catabolism of sugars and signalling of the nutritional state is regulated by complex interactions of sugar intake systems, adenylate cyclase, and transcriptional regulation.
Tidal flat development is regulated by complex estuarine processes.
Introduction Sleep and wakefulness are strong interconnected stages regulated by complex mechanism in the basal brain.
It is regulated by complex feedback between the stomach and central nervous system.
For instance, aspects of regeneration are often regulated by complex mechanisms of activation for several growth regulatory pathways in damaged tissue.
Vertebrate genes controlling critical developmental processes are often regulated by complex sets of global enhancer sequences, located at a distance, within neighboring gene deserts.
Cellular behaviors, such as differentiation, are regulated by complex ligation processes involving cell surface receptors, which can be activated by various divalent metal cations.
They are repressed at alkaline pH condition (Linnemannstöns et al. 2002) and by high amount of nitrogen in an AreA-independant manner and are regulated by complex regulatory network (Wiemann et al. 2009).
Expression and release of PGI-2 and ET-1 in the ECs are regulated by complex signals; we did not study the mechanism for their reducing expressions and/or release in this study.
Stem cell differentiation is regulated by complex repertoires of signaling ligands which often use multivalent interactions, where multiple ligands tethered to one entity interact with multiple cellular receptors to yield oligomeric complexes.
Major complications include: cells are themselves regulated by complex intracellular signaling networks; individual cells are heterogeneous; and output of any one cell can recursively become an additional input signal to other cells.
