Based on these findings, we conclude that OPN overexpression in ENU-induced gliomas occurs within a specific subset of intratumoral glial fibrillary acidic protein-positive cells and becomes evident at the stage of tumor progression.
Effect of NADPH oxidase inhibition on the expression of kidney injury molecule and calcium oxalate crystal deposition in hydroxy-L-proline-induced hyperoxaluria in the male Sprague-Dawley rats.
These findings suggest that osteopontin expression and macrophage accumulation may play a role in the tubulointerstitial injury in diabetic nephropathy, and that inhibition of osteopontin expression may be one of the mechanisms by which blockade of the renin-angiotensin system confers a renoprotective effect.
Taken together, these results indicate that Opn plays an important role in the development of albuminuria, possibly by modulating podocyte signaling and motility.
The present study evaluates association between SPP1 polymorphisms and SLE in a large cohort of 1141 unrelated SLE patients [707 European-American (EA) and 434 African-American (AA)], and 2009 unrelated controls (1309 EA and 700 AA).
We can speculate that these sequence variants (or others in perfect linkage disequilibrium) create a predisposition to high production of OPN, and that this in turn may confer susceptibility to SLE.
