Fig. 3. Expression of Bufo urea transporter (UT) mRNA relative to GAPDH
mRNA in the kidney (A) and urinary bladder (B) of marine toads exposed to dry
or hyper-saline conditions. The signal level of each band in Ai, Bi is
presented as a ratio of Bufo UT/GAPDH mRNA in Aii, Bii, respectively.
Values are means ± s.e.m. N=5. Bars with different letters
have significantly different values (ANOVA, P<0.05).
