1. Intraortic suprarenal infusion in vivo of New Zealand White rabbits with plasma from patients with the nephrotic syndrome reduced the number of anionic sites labelled by the cationic polymer polyethyleneimine in the lamina rara iterna to 14.0 +/- 2.7 per 1000 nm of lamina rara interna (mean +/- SD) compared with 18.7 +/- 2.1 (P less than 0.005) after(More)
Ammonium has previously been found to inhibit transport in a number of tissues. The present experiments were designed to evaluate the effect of ammonium chloride on transepithelial voltage (VTE) and cation transport in the isolated rabbit cortical collecting tubule perfused in vitro. Peritubular NH4Cl (2-10 mM) inhibited VTE in these tubules independent of(More)
To investigate whether obesity induces a leptin-Notch signaling axis in breast cancer (BC), leptin-induced Notch was determined in human MCF-7 and MDA-MB231 and mouse E0771 cells and in E0771-BC hosted by syngeneic lean and diet-induced obesity (DIO) C57BL/6J female mice. Lean and DIO mice were treated for 3 weeks with leptin inhibitor (PEG-LPrA2) 1 week(More)
Nonionic diffusion and diffusion equilibrium of ammonia have been generally accepted as the mechanism of urinary ammonium excretion. However, these characteristics have not been examined directly in vitro. In the present studies, nonionic diffusion and diffusion equilibrium of ammonia were examined in rabbit cortical collecting tubules perfused in vitro.(More)
IgA lambda multiple myeloma was diagnosed in a 58-year-old white woman after the onset of nephrotic syndrome. Serial renal histology demonstrated progressive mesangial proliferative glomerulonephritis. Electron microscopy revealed subepithelial electron dense deposits. Immunofluorescence microscopy demonstrated granular staining of peripheral capillary(More)
Notch, IL-1 and leptin are known pro-angiogenic factors linked to breast cancer development, tumor aggressiveness and poor prognosis. A complex crosstalk between these molecules (NILCO) has been reported in breast cancer cell lines. However, whether NILCO biomarkers are differentially expressed in estrogen responsive (ER+), unresponsive (ER-) and triple(More)
Leptin increases vascular endothelial growth factor (VEGF), VEGF receptor-2 (VEGFR-2), and Notch expression in cancer cells, and transphosphorylates VEGFR-2 in endothelial cells. However, the mechanisms involved in leptin's actions in endothelial cells are not completely known. Here we investigated whether a leptin-VEGFR-Notch axis is involved in these(More)
