Abstract:
OBJECTIVE:Urea transporter-B (UT-B), highly expressed in erythrocyte, confers specific permeability to urea, urea analogues and water. The purpose of this study was to determine the hemorheological properties of UT-B null erythrocyte using a series of biophysical techniques. METHODS AND RESULTS:The blood was taken from UT-B knockout and wild-type mice and the hemorheological parameters were measured. The UT-B inhibitor, PU-14, was used to treat the erythrocyte of wild-type mice in vitro and the deformability of the treated erythrocyte was analyzed. The results showed that UT-B knockout improves the hemorheological properties of erythrocyte, including increased erythrocyte deformation index, small deformation index, orientation index, low osmotic fragility and high electrophoretic rate. The UT-B inhibitor PU-14 had the similar effect as UT-B knockout on the deformation indices. The whole blood viscosity in UT-B knockout mice showed reduction trend as compared to wild-type mice. CONCLUSIONS:The data indicate that UT-B is involved in the regulation of hemorheology, which suggests that UT-B may be a potential therapeutic target for improving the hemorheology in some metabolic and hereditary diseases.
