Fig. 10. Immunoblot of the stress-associated proteins OSR1 (A) and SPAK (B),
comparing expression in freshwater (FW)- and seawater (SW)-acclimated animals.
Quantitative western analysis revealed significantly higher level of OSR1 and
SPAK expression in FW- as compared to SW-acclimated animals for the gill and
opercular epithelium (oe; N=3, *P<0.05) with
the difference in OSR1 expression being more marked than that for SPAK.
