GnRH-Related Neurohormones in the Fruit Fly Drosophila melanogaster.
Title: GnRH-Related Neurohormones in the Fruit Fly Drosophila melanogaster.
We find two STIM-regulated peptides, Corazonin and short Neuropeptide F, to be required for NR larvae to complete development. Further, a set of secretory DLP (Dorso lateral peptidergic) neurons which co-express both peptides was identified

Results show that the Crz action triggers transcriptional changes in the adipocytes that include stress genes and one gene involved in metabolism.
Title: Systemic corazonin signalling modulates stress responses and metabolism in Drosophila.
Findings indicate that short neuropeptide F (sNPF) and corazonin (CRZ) co-released from a small set of neurons regulate insulin-producing cells (IPCs) stress resistance and metabolism.
Title: Identified peptidergic neurons in the Drosophila brain regulate insulin-producing cells, stress responses and metabolism by coexpressed short neuropeptide F and corazonin.
CrzR-associated signaling pathway is critical for ethanol detoxification via Crz-dependent regulation of ALDH activity and Crz-independent transcriptional regulation of ADH.
Title: Regulation of ethanol-related behavior and ethanol metabolism by the Corazonin neurons and Corazonin receptor in Drosophila melanogaster.
The work presented here identifies two genes, apt and crz, which mediate the fly's sensitivity to ethanol-induced sedation.
Title: A small group of neurosecretory cells expressing the transcriptional regulator apontic and the neuropeptide corazonin mediate ethanol sedation in Drosophila.
Data show that altered corazonin neuron physiology leads to fundamental differences in locomotor activity, and these effects were also sex-dependent.
Title: Corazonin neurons function in sexually dimorphic circuitry that shape behavioral responses to stress in Drosophila.
The tissue-, stage-, and sex-specific expression of Crz and the association of Crz with the function of the retrocerebral complex suggest diverse roles for this neuropeptide in Drosophila.
Title: Developmental regulation and functions of the expression of the neuropeptide corazonin in Drosophila melanogaster.
We show that the 504-bp 5' upstream sequence is the shortest promoter directing reporter activities in all Drosophila Corazonin neurons.
