In the absence of SLC26A6, oxalate transport is largely passive and paracellular. Transepithelial absorption and secretion of [¹⁴C]oxalate were measured simultaneously with fluxes of [³H]mannitol across duodenum of wild-type and Slc26a6-null mice. The data are expressed as the means ± SEM (n = 8). *P < 0.05 versus oxalate absorptive flux.
