Psi is required for maintaining endogenous dMYC mRNA in larval wings and the impaired growth in Psi knockdown wings depends on down regulation of dMYC. (A and B) ser-GAL4-driven dMYC overexpression alone did not increase wing size, but suppressed the Psi RNAi wings up phenotype. dMYC RNAi driven by ser-GAL4 alone reduced compartment size to result in a wings up phenotype, and also enhanced the Psi RNAi phenotype. (C and D) qPCR for Psi (C) and dMYC (D) following tubulin-GAL4 driven knockdown of UAS-RNAi lines (as marked) in larval wing discs.
