Transport characteristics and membrane expression of AQP1_F56G/H180G and AQP10_G62F/G202H. Experimental conditions were as described in Fig. 4. Data expression is also as described in Fig. 4. (A) Si influx. Data are expressed as means ± SE of 10 oocytes among eight to nine experiments. The asterisk is used to indicate that the mean is significantly different statistically (*, P < 0.05) compared with the wild-type channel. (B) Water permeability. Data are expressed as means ± SE of three to five oocytes among four to five experiments. (C) AQP expression at the cell surface (EXPcs). Data are expressed as means ± SE among three to four experiments.
