Urothelium synthesizes a group of integral membrane proteins called uroplakins, which form two-dimensional crystals (urothelial plaques) covering >90% of the apical urothelial surface. We show that the ablation of the mouse uroplakin III (UPIII) gene leads to overexpression, defective glycosylation, and abnormal targeting of uroplakin Ib, the presumed partner of UPIII. The UPIII-depleted urothe...
Uroplakins (UP), a group of integral membrane proteins, are major urothelial differentiation products that form 2D crystals of 16-nm particles (urothelial plaques) covering the apical surface of mammalian bladder urothelium. They contribute to the urothelial barrier function and, one of them, UPIa, serves as the receptor for uropathogenic Escherichia coli. It is therefore important to understan...
In Xenopus laevis, sperm-egg interaction promotes partial proteolysis and/or tyrosine phosphorylation of uroplakin III (UPIII) and the tyrosine kinase Src, which both localize to the cholesterol-enriched egg membrane microdomains (MDs). Here we show that sperm promote proteolysis and/or tyrosine phosphorylation of UPIII and Src in MDs isolated from ovulated and unfertilized eggs (UF-MDs). An an...
The giant anteater (Myrmecophaga tridactyla) is a vulnerable species from Central and South America, considered possibly extinct in Belize, Guatemala, El Salvador, Uruguay. Due to the species’ conservation reproductive importance, this research aimed characterize morphology, histochemical, immunohistochemical, ultrastructural feature of prostate gland. For this, we collected 11 glands performed...
Skin and bladder epithelia form effective permeability barriers through the activation of distinct differentiation gene programs. Using a genome-wide gene-expression study, we identified transcriptional regulators whose expression correlates highly with that of differentiation markers in both the bladder and skin, including the Grainyhead factor Get1/Grhl3, which is already known to be importan...
Although water, small nonelectrolytes, and gases are freely permeable through most biological membranes, apical membranes of certain barrier epithelia exhibit extremely low permeabilities to these substances. The role of integral membrane proteins in this barrier function has been unclear. To study this problem, we have ablated the mouse gene encoding uroplakin III (UPIII), one of the major pro...
PURPOSE Previous study has shown that the absence of uroplakin II can cause urinary tract dysfunction, including vesicoureteral reflux and renal abnormalities, as well as micturition pattern changes. We developed a simple surrogate measure of bladder function using ultraviolet visualization of urinary voiding patterns in a uroplakin II knockout mouse animal model. MATERIALS AND METHODS Three ...
