Fig. 6. HIF-1
mRNA amounts in the liver (A), gills (B) and kidney (C) of
fish exposed to hypoxia at 26°C, 18°C or 8°C. Results are shown as
fold increase compared to levels in normoxic fish at 26°C and are means
± s.e.m. of 510 fish. Temperature has a significant effect on
the hypoxia response of HIF-1
mRNA in the liver (P<0.05),
gills (P<0.01) and kidney (P<0.01) of crucian carp
(two-way ANOVA). Asterisks denote significant difference (P<0.05,
P<0.01, P<0.01, P<0.001,
P<0.01 and P<0.001 for liver 8°C 48 h, gills
26°C 6 h, gills 26°C 24 h, gills 26°C 48 h, gills 8°C 6 h and
kidney 8°C 48 h, respectively) to normoxic fish at the same temperature
(HolmSidak post test).
