    ANIMAL & CELL MODELS
  • Nephrolithiasis in the Slc26a6(-/-) mouse is accompanied by 50-75p100 reduction in intestinal oxalate secretion with unchanged intestinal oxalate absorption
  • collagen fibrils in bone were thinner and less organized in dtd compared to wild-type mice, suggesting that the low bone mass observed in mutant mice could possibly be linked to the different bone matrix compositions/organizations in dtd mice triggering changes in osteoblast and osteoclast activities
