  • Title: [Transforming growth factor as a marker beta of nephrogenetic disturbance in congenital obstructive uropathies].
    Author: Leonova LV, Severgina ES, Popova OP, Konovalov DM, Petruchina IuV, Simonova NA.
    Journal: Arkh Patol; 2007; 69(4):35-8. PubMed ID: 17926575.
    Abstract:
    The paper presents the results of morphological and immunohistochemical studies of the kidneys and ureters obtained at surgery in 25 children aged from 2 days to 3 years who had congenital obstructive uropathies. The morphological study revealed varying renal tissue dysplasia concurrent with dysplasia of the prepelvic or distal ureter. Immunohistochemically, the kidneys showed a pronounced expression of TGFbeta1, TGF(1R1 and R2 in the nephrocytes of non-differentiated and collecting tubules, in the tubular lumen, vascular walls, in the interstitial tissue and cell interstitial infiltrates, on the hypoplastic and disoriented ureteral smooth muscle fibers. The use of the ILIAS-method to determine urinary TGF levels before and after surgery indicated a direct correlation of these indices with the degree of renal tissue dysplasia.
