Differential Cl- and HCO3- mediated anion secretion by different colonic cell types in response to tetromethylpyrazine

Figure 4 Effect of inhibitors of basolateral anion transporters on TMP-induced I_SC responses. Values are mean ± SE; ^cP < 0.001. A: Comparison of TMP (1 mmol/L)-induced I_SC responses in T84 cells in the absence and presence of basolateral addition of bumetanide (100 μmol/L); B: Comparison of TMP (5 mmol/L) -induced I_SC responses in Caco-2 cells in the absence and presence of basolateral addition of inhibitors indicated.
