| Research Abstract |
Midkine (MK) is a mutepotentioal heparin-binding growth factor with migration-promoting activity for neutrophils, macrophages and neurons. Although MK expression is mainly limited in the course of nephrogenesis, the enhanced expression of MK is also observed in the tubular epithelial cells in the diseased kidney. The role of MK in tubulointerstitial injuries as well as in glomerular injuries was studies. MK induces the chemotaxis of inflammatory leukocytes into the tubulointerstitium at least partially through the induction of MCP-I and MIP-2, and that MK contributes the aggravation of ischemia-induced tubulointerstitial damage.
MK anti-sense oligonucleotide (ODN) distributes in the proximal tubular epithelial cells, which is the main part for de novo MK expression, after intravenous injection, and significantly reduced the expression of MK in the tubules. Consequently, MK antisense ODN successfully block the ischemic reperfusion injuries in the tubulointerstitium.
These results strongly suggest that MK antisense ODN appears to be a candidate for the novel therapeutic approaches in ischemia-induced tubulointerstitial injuries.
