Abstract

The steroid hormone 20-hydroxyecdysone (20E) plays a critical role in insect development, particularly in larval molting and larval-pupal transition. Studies have indicated that 20E transmits its signal via a G protein-coupled receptor (GPCR)-mediated non-genomic pathway before a genomic pathway is initiated. However, the mechanism by which a 20E signal is desensitized remains unclear. We proposed that β-arrestin1 interacts with ecdysone-responsible GPCR (ErGPCR1) to desensitize a 20E signal in the lepidopteran insect Helicoverpa armigera. Results showed that β-arrestin1 was highly expressed in various tissues during metamorphosis. β-Arrestin1 knockdown by RNA interference in larvae caused advanced pupation and a larval-pupal chimera. The mRNA levels of 20E-response genes were increased after β-arrestin1 was knocked down but were decreased after β-arrestin1 was overexpressed. 20E induced the migration of β-arrestin1 from the cytosol to the cytoplasmic membrane to interact with ErGPCR1. The inhibitors suramin and chelerythrine chloride repressed 20E-induced β-arrestin1 phosphorylation and membrane migration. With ErGPCR1, 20E regulated β-arrestin1 phosphorylation on serines at positions 170 and 234. The double mutation of the amino acids Ser170 and Ser234 to asparagine inhibited phosphorylation and membrane migration of β-arrestin1 in 20E induction. Therefore, 20E via ErGPCR1 and PKC signaling induces β-arrestin1 phosphorylation; phosphorylated β-arrestin1 migrates to the cytoplasmic membrane to interact with ErGPCR1 to block 20E signaling via a feedback mechanism.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
