Fig. 5. The ratio of liver arginase genes, Onmy-ARG01 and Onmy-ARG02, mRNA levels relative to ß-actin mRNA levels from northern blot analysis after 6 weeks of feeding (control) or fasting in juvenile O. mykiss. Total RNA (10 µg) was loaded into each lane. Intensity of the signal was quantified by denisitometry (see Materials and methods). Means ± S.E.M. (N=4). (A) Onmy-ARG01:ß-actin levels, (B) Onmy-ARG02:ß-actin levels. Asterisk denotes significant difference from fed group (P<0.05).
