The temporal pattern of EcR RNA expression was carefully studied and related to times of ecdysone pulses. Peaks of the 5kb EcR-A RNA occur in mid-embryogenesis and early and late in pupation.
The temporal pattern of EcR RNA expression was carefully studied and related to times of ecdysone pulses. The strongest peak of EcR-B1 RNA expression occurs in late third instar larvae. Smaller peaks are observed during late embryonic, late first and second instar larval, and mid pupal stages.
At 0h APF, reticular neuropil associated glial cells (astrocyte-like cells) express "EcR-B1" (EcR-RB), but not "EcR-A" (EcR-RA, EcR-RD) <up>isoform identities obtained from UniProt</up>.
EcR isoform "A" is uniformly distributed in egg chambers at all stages. Isoform "B1" is more highly expressed in follicle cells than germline cells and shows a fourfold enrichment in anterior follicle cells at early oogenesis stage S9. The enrichment is reduced by mid stage 9 and absent by stage 10.
