As an example, it was demonstrated that, by administrating a synthetic MRI probe for sensing Zn2+, the functionality of insulin-producing β-cells in healthy mice could be determined in vivo (Lubag et al., 2011).
Collectively, these data indicate that the improvements in whole-body and skeletal muscle insulin action after long-term antagonism of ANGII action in TGRs occur independently of modulation of the functionality of these insulin-signaling elements.
Taken together, these data show that the functionality of the stimulus-coupling insulin secretion machinery of Aldh1b1tm1lacZ null beta cells is impaired at multiple levels.
In terms of functionality, this model allowed the efficient prediction of insulin permeability in which the presence of mucus, the less tight character between Caco-2 and HT29-MTX epithelial cells and the 3D assembly were critical factors.
The rBM-MSCs in the coculture islets maintained their viability and functionality as shown by the increased level of insulin secretion in comparison with monocultures.
The dyes used in the photopolymerization process also reduced the functionality of the beta cells as insulin secretion decreased significantly with increasing dye concentration [44].
Our previous similar kind of computational analysis shows that the N-glycosylation sites and O-glycosylation sites are vital for the functionality of the proteins in the insulin signalling pathway proteins such as IRS and GLUT4 [ 67, 92].
To evaluate the functionality of the islets, we examined their cellular insulin content and insulin-releasing indices.
Typical functional assays to assess the functionality of the isolated islets include in vitro glucose-stimulated insulin release tests, and in vivo function determined by transplanting islets into small diabetic, immunodeficient rodents, such as nonobese diabetic/ scid mice [ 31].
To further understand the mechanisms responsible for the delayed development of insulin resistance in IL-1RI−/− mice on HFD, we assessed adipose morphology and functionality.
Thus, on the basis of our preliminary research findings, it could be concluded that the developed biocompatible Insulin-Mt-PLGA nanocomposites with double functionality of low pH stability and mucoadhesivity may offers promise to overcome the difficulties associated with the oral drug delivery of insulin.
