Activities of Amphioxus GH-Like Protein in Osmoregulation: Insight into Origin of Vertebrate GH Family

Figure 6

Induction of igfl expression by rGHl. (a) Expression of igfl in the cultures of the hepatic caecum in response to rGHl or rzGH (concentrations ranging from 10 ng/ml to 1000 ng/ml). (b) Expression of igfl in the cultures of the gill in response to rGHl or rzGH (concentrations ranging from 10 ng/ml to 1000 ng/ml). (c) Expression of gh/prllbp in the hepatic caecum of amphioxus injected with saline, rGHl, or rzGH. (d) Expression of igfl in the gill of amphioxus injected with saline, rGHl, or rzGH. Data were from 3 independent experiments and expressed as mean ± SEM. The symbol shows .
