Genetic manipulation of InR/Akt1/PI3K modifies the dilp2-induced lethality. Relative viability of the sd > dilp2 flies was determined in combination with loss of function mutations in InR, Akt1, or PI3K, which are components of the insulin/IGF signaling pathway. dilp2- induced semi-lethality was markedly improved by reduction of InR or Akt1, but enhanced by reduction of PTEN (A). Relative viability of the sd > dilp2 flies in combination with loss-of-function mutations in Tor and S6K (B). The Tor/S6K pathway may not contribute to mediating the semi- lethality of dilp2-overexpressing flies. Student t-test was performed to analyze statistical significance. *p < 0.05, **p < 0.01.
