SLC34A2 and neoplasm: Interestingly, NTera2 tumor-bearing mice had significantly higher Slc34a1 and bone gamma-carboxyglutamic acid-containing protein (Bglap) expression in testis compared with nude mice without tumors but no change in Slc34a2, suggesting that the effect induced by the tumor was cFGF23 or FGF23 independent (Figure 3C).
