The surface of each type of filler was treated to either promote or inhibit particle matrix adhesion.
For clinical use, chelators are designed to either promote clearance of excess iron by excretion or maintain safe iron levels in situations that pose a risk for developing toxic levels of iron, e.g., following multiple blood transfusions for β-thalassaemia (Porter, 2009; Brittenham 2011).
The activity of the downstream target of p38, USF-1, is modulated through post-translational modification, again depending on the nature and dose of UV exposure, either promoting gene expression or inducing a transcriptional block [17], [18].
However, in addition to this role, a key aspect of the function of RACK1 is its capacity to modulate the enzymatic activity of its binding partners, either promoting or suppressing the activity of bound enzymes.
Cells of the immune system are critical components of this extrinsic network of cancer regulators, contributing significantly to the microenvironment of most cancers and either promoting or inhibiting the initiation and progression of this disease.
Such a spatial co-localization indicates a direct exposure of the axons to these molecules and would suggest a relevant role for them in the growth of the antler nerves, either promoting axon regrowth or coping with the axon trophic requirements.
By down-regulation of protein-encoding genes either promoting or inhibiting cell proliferation, several miRNAs have been shown to function as tumorsuppressors and oncogenes [ 5, 8- 11].
Tumour cells simultaneously secrete proteases (uPA) and their inhibitors (PAI-1), and the balance between the two precisely regulates the level of extracellular proteolysis, thus either promoting or suppressing angiogenesis (Folkman et al, 2001).
THIS year's presidential election has prompted plenty of advertisements that either promote or attack the candidates.
