Fig. 5. Effect of HuD and ELAV ectopic expression on UgGA and UgGH reporter expression. UgGA and UgGH expression was examined at the RNA level by in situ hybridization in the third instar larval wing discs. No apparent change in UgGA mRNA level is observed when either UAS-HuD (A) or UAS-elav (B) are ectopically expressed using dpp-GAL4. However, in UgGH-expressing discs, the mRNA level is increased along the dpp-GAL4 expression pattern by ectopic expression of either UAS-HuD (C) or UAS-elav (D).
