GO analysis showed that G-protein coupled receptor protein signaling pathway, intrinsic to membrane, cell junction and ion transport were significantly enriched, and KEGG analysis indicated that neuroactive ligand-receptor interaction was the only significantly enriched pathway (Table IV).
The dynamic inverse relationship between proteases and protease inhibitors is indispensable for Sertoli-germ cell junction disassembly to release elongated spermatids into the tubule lumen [24].
Out of the three MetS-FL miRs identified in our previous cohort, the has-miR-142-3p has been shown to have functional multiplicity by being able to directly regulate structural proteins within the cell junction [18], participate in the initiation of LPS-induced inflammatory signaling in immune and dendritic cells [19], and be implicated in systemic metabolic stress through its upregulation in the adipose tissue of mice fed a high-fat diet [20] and in obese children [21].
Regulation of cell junction dynamics by cytokines in the testis: A molecular and biochemical perspective.
Because has encodes atypical protein kinase C, which requires Bves to regulate cell junction, and the zebrafish has mutant exhibits loss of normal retinal lamination [24], we further investigated whether Bves is required for retinal lamination.
No specialized cell junction was apparent when two or more cells were in close proximity.
The importance of the IF-cell surface complex has been highlighted by the discovery of mutations in genes encoding IF structural proteins, as well as cell junction proteins that result in blistering diseases of the skin (Steinert and Bale, 1993; Fuchs, 1994; McLean and Lane, 1995).
Hormonal regulation of cell junction permeability: upregulation by catecholamine and prostaglandin E1.
Extracellular matrix components such as fibronectin and matrix metalloproteinases also play a crucial role during development especially in developing cell to cell junctions. The parasympathetic nerve supply aids in normal development of the salivary glands.
A decreased mucous layer, degeneration of the cell junctions and increased number of microvilli (32) were observed in the SEM observations of IC patients.
ZO-1 was observed uniformly in the epithelial cell junctions of both Tric-/- and WT ES.
The choline-geranic acid formulation also was shown to be adept at penetrating two final barriers - the layer of mucus lining the intestine and the tight cell junctions of the intestine wall, through which large-molecule drugs such as insulin cannot easily pass.
