Outline of Final Research Achievements

Osteopontin (OPN) plays a crucial role in the formation of renal calcium crystals, which are primarily induced by renal tubular cell injury. We have previously shown that the impaired RGD sequence,which serves as an adhesion motif that promotes cell attachment, inhibits renal crystal formation by using OPN-transgenic mice and OPN-knockout mice. In this study, thrombin-cleaved osteopontin plays a nonredundant role in renal crystal formation, which is a complex multistep process. A specific anti-OPN antibody contributes to the remarkable inhibition of early stage of renal crystal formation by suppressing RTC injury, the attachment of crystals to renal epithelium cells or crystal growth.
