No significant difference was found in the levels Gαs between the hypoxic and the normoxic group (Fig. 1). The level of Gαi on the other hand, was significantly higher (22.3 %) in the hypoxic group than in the normoxic group, 115 % and 94 % of the internal standard respectively (Fig. 1)

In contrast to the embryos, hypoxia significantly increased Gαs in the juveniles by 21.5 % compared to the normoxic control (Fig. 2), though no significant difference in Gαi levels was found between the hypoxic and normoxic groups (Fig. 2).
