| Research Abstract |
In this study, the involvement of tubuloglomerular feedback (TGF) abnormality was studied. First, macula densa specific NKCC homolog was identified based on homology cloning strategy. Second, its expression was principally studied by in situ PCR hybridization method. Subsequently, the changes of its gene expression in urinary tract obstruction (UTO) model and non-insulin dependent diabetes mellitus model (NIDDM) were studied. As a results, expression of new clone was decreased in NIDDM, suggesting that its abolished expression might generate the suppression of TGF and expose high pressure to glomerulus, causing glomerulosclerosis.
