Figure 5. Fatbody dSir2 regulates dilp5 meditated Insulin Signaling. (A-C) Relative dilp5 levels in the heads of (A) whole body dSir2RNAi (B) fatbody dSir2RNAi and (C) muscle dSir2RNAi flies, with respective controls, under fed and starved conditions (n = 24). Relative expression of (D) dInR and (E) d4eBP in fatbody dSir2RNAi flies under fed and starved conditions (n = 24). (F) Starvation survival of fatbody dSir2 knockdown (pSw-S1106-gal4>+/+;dSir2RNAi + RU486) and control (pSw-S1106-gal4>+/+;dSir2RNAi - RU486) flies, fatbody dSir2 knockdown in chico heterozygote flies (pSw-S1106-gal4>ch+/-; dSir2RNAi + RU486) and (pSw-S1106-gal4>ch+/-; dSir2RNAi- RU486) (statistical significance indicated in
