内容記述
Several angiogenesis-related factors are known to play important roles in the pathogenesis of kidney disease. Vasohibin-2 (VASH-2) was recently reported as a novel proangiogenic factor. Although VASH-2 was demonstrated to accelerate tumor angiogenesis, its roles in non-tumor processes including renal disease have not been well elucidated yet. Here, we performed a retrospective study including an immunohistochemical analysis of human kidney biopsy specimens from 82 Japanese patients with a variety of kidney diseases, and we evaluated the correlations between the immunoreactivity of VASH-2 and the patients’ clinicopathological parameters. VASH-2 immunoreactivity was detected in varying degrees in renal tubules as well as in peritubular capillaries and vasa recta. The cortical and medullary tubule VASH-2+ scores were correlated with the presence of hypertension, and the medullary tubule VASH-2+ score was significantly correlated with the blood glucose (p=0.029, r=0.35) and hemoglobin A1c levels (p=0.0066, r=0.39). Moreover, decreased VASH-2+ scores in the vasa recta were associated with reduced renal function (p=0.0003). These results suggest that VASH-2 could play an important role in the pathogenesis of renal diseases, and that VASH-2 is closely associated with hypertension and impaired glucose tolerance.
