Fig. 7. Effects of 8-Br-cAMP on TH protein accumulation, phosphorylation and activity in peptide hormone mutants. (A) Western blots showing epidermal TH and phospho-Ser32-TH levels 2.5 hours after eclosion in untreated flies or flies injected with 8-Br-cAMP at eclosion. (B) TH activity in the same organisms. Each value is the mean+s.e.m. of a minimum of three independent experiments.
