The small subunits of human and mouse DNA polymerase epsilon are homologous to the second largest subunit of the yeast Saccharomyces cerevisiae DNA polymerase epsilon.

Human DNA polymerase epsilon is composed of a 261 kDa catalytic polypeptide and a 55 kDa small subunit of unknown function. cDNAs encoding the small subunit of human and mouse DNA polymerase epsilon were cloned. The predicted polypeptides have molecular masses of 59.

Long-term graft outcome is not necessarily affected by delayed onset of graft function and early acute rejection.

Background: Both acute rejection episodes and delayed graft function (DGF) have been shown to be associated with decreased 1-year renal allograft survival. In our center, the incidence and the intensity of acute rejection episodes have been reduced by cyclosporine-based triple-drug therapy. We have also shown that DGF alone is not a risk factor for long-term graft survival.

Does delayed kidney graft function increase the risk of chronic rejection?

The impact of delayed graft function (DGF) on later renal graft loss due to chronic rejection was studied in a single center using uniform protocol for organ procurement and posttransplant patient care. DGF function was observed in 34% of 829 consecutive first cadaveric renal transplants in adults and in 47% of 169 retransplantations (P < 0.05).
