Figure 1 shows PKC activity of primary human mesothelial cells at various glucose levels (i.e., low glucose, 60 mM or 150 mM glucose). The PKC activity was determined in the presence or absence or PMA, an activator of PKC.
Figure 2 shows the effect of treatment with vitamin E on PKC activity of human primary mesothelial cells. The mesothelial cells were exposed to low or high (150 mM) levels of glucose in the presence or absence of PMA, an activator of PKC, and the presence or absence of vitamin E, a PKC inhibitor.
Figure 3 shows PKC activity of primary human mesothelial cells cultured in low glucose concentrations, high glucose concentrations (i.e., 60 M or 150 mM), or mannitol. The PKC activity was determined in the presence or absence or PMA, an activator of PKC.
Figure 4 shows DAG activity of transformed mesothelial cells at low glucose levels (5.5 mM) and high glucose levels (60 mM).
RtailpiH Description Peritoneal dialysis for chronic renal failure is used by some patients with renal failure. The fluid for peritoneal dialysis uses glucose at 400-mM range. While not wishing to be bound by theory, it appears that at this concentration level, glucose causes complications which can lead to decreasing permeability between the peritoneal dialysis fluid and the blood compartment. The elevation of high glucose causes changes in the cells lining the peritoneum. The invention is based, in part on, PKC activation, which is believed to cause this chronic decrease in the exchange between the peritoneal fluid and a vascular compartment.
PKC activation induced by hyperglycemia either in the peritoneal fluid or in the blood causes cells to behave abnormally. The inhibition of PKC β isoform by the inhibitor LY333531 can prevent many of the vascular changes induced by glucose levels up to 20-3 OmM. The higher concentration of glucose as used in peritoneal dialysis will also increase PCK activation. Inhibition of PKC activation using a PKC β, e.g., βl or β2, γ, δ, or other isoform, or combinations thereof, inhibitor will prevent the thickening and the decrease in exchange between peritoneal and vascular compartments, which will improve the efficiency of peritoneal dialysis for chronic renal failure.
As shown in Figures 1-3, exposure of human mesothelial cells, which are the cells that line the peritoneum, to glucose levels of 60 mM or 150 mM results in an increase of PKC activity. These concentrations of glucose are standard for dialysis. In addition, as shown in Figure 2, exposure of these cells to vitamin E, which is an inhibitor of PKC, resulted in a decrease of PKC activity. It was also found that high glucose levels of 60 mM or 150 mM increased DAG activity. These results demonstrate that glucose concentrations used for peritoneal dialysis activate the DAG-PKC pathways. It has been reported that activation of these pathways increases fibrosis. These results also show that inhibitors of PKC such as vitamin E decrease PKC activity. Therefore, inhibition of PKC can decrease fibrosis and reduce or prevent permeability failure of the peritoneal membrane. Other embodiments are within the following claim.
