Intestine absorption of intact green fluorescent protein (GFP) and its following accumulation in the renal proximal tubule cells after its intragastric administration have been established by confocal microscopy in the rat and frog. Reabsorbed GFP was revealed in the endosomes and lysosomes of the proximal tubule cells by the methods of GFP photooxidation(More)
PURPOSE Restoration of the p53 function in tumors is a promising therapeutic strategy due to the high potential of p53 as tumor suppressor and the fact that established tumors depend on p53 inactivation for their survival. Here, we addressed the question whether small molecule RITA can reactivate p53 in neuroblastoma and suppress the growth of neuroblastoma(More)
Loss-of-function (LOF) mutations in the endothelial cell (EC)-enriched gene endoglin (ENG) cause the human disease hereditary haemorrhagic telangiectasia-1, characterized by vascular malformations promoted by vascular endothelial growth factor A (VEGFA). How ENG deficiency alters EC behaviour to trigger these anomalies is not understood. Mosaic ENG deletion(More)
Elevation of the interstitial fluid pressure (IFP) of carcinoma is an obstacle in treatment of tumors by chemotherapy and correlates with poor drug uptake. Previous studies have shown that treatment with inhibitors of platelet-derived growth factor (PDGF) or vascular endothelial growth factor (VEGF) signaling lowers the IFP of tumors and improve(More)
Imatinib causes increased turnover of stromal collagen, reduces collagen fibril diameter, enhances extracellular fluid turnover and lowers interstitial fluid pressure (IFP) in the human colonic carcinoma KAT-4/HT-29 (KAT-4) xenograft model. We compared the effects of imatinib on oxygen levels, vascular morphology and IFP in three experimental tumor models(More)
In experiments on rats aged 5, 12, and 25 days and on adult rats, absorption of yellow fluorescent protein (YFP) in small intestine was shown, with its subsequent entry to kidney with blood flow and accumulation in cells of the nephron proximal segment. With age, intensity of the YEP absorption in the gut decreased; the YEP accumulation in kidney was(More)
In experiments of the 5, 12 and 25-day old rat pups and adult rats in has been shown that after administration of yellow fluorescent protein (YFP) into stomach, its partial absorption in the non-degraded state in the small intestine takes place, with subsequent transport to kidney with blood flow and accumulation in cells of the proximal nephron segment.(More)
Hypoxia in the embryo is a frequent cause of intra-uterine growth retardation, low birth weight, and multiple organ defects. In the kidney, this can lead to low nephron endowment, predisposing to chronic kidney disease and arterial hypertension. A key component in cellular adaptation to hypoxia is the hypoxia-inducible factor pathway, which is regulated by(More)
Yellow fluorescent protein (3.6 ng) was administered through a catheter into the Wistar rat intestine lumen. By the method of confocal microscopy it has been established that as soon as in 3 min this protein appears in the epithelial cells of ileum, is absorbed into the blood and accumulated in cells of the nephron proximal segment, not being revealed in(More)
