Fig. 3 All four zebrafish igf genes are functional.

(A) Microinjection of each of the 4 zebrafish IGF mRNA into zebrafish embryo resulted in elevated Akt phospholylation. GFP, IGF-1a, -1b, -2a, and -2b mRNA was injected into zebrafish embryos at 1-2 cell stage. The injected embryos were raised to shield and 15 somite stages. Lysates were prepared and subjected to SDS-PAGE followed by immunoblot analysis using antibodies against total and phosphorylated Akt (Akt-P). (B) Densitometric analysis result of (A). The phosphorylated Akt/total Akt ratio was calculated and expressed as % of the control (GFP mRNA injected) group. Grey bars represent the shield stage groups, and dark bars represent the 15 somite stage groups. Values are means±SE (n = 3). *p<0.01 compared with the control group.
