Synaptic Targets of Circadian Clock Neurons Influence Core Clock Parameters

Eva Scholz-Carlson, Aishwarya Ramakrishnan, Aljoscha Nern, John Ewer, Maria P. Fernandez

This study identifies SLP316 neurons as synaptic targets of circadian clock neurons in Drosophila, showing that modulating their activity alters circadian period and behavior.

Characterization Eclosion Hormone Receptor function reveals differential hormonal control of ecdysis during Drosophila development.

Valeria Silva, Robert Scott, Paulina Guajardo, Haojiang Luan, Ruben A Herzog, Benjamin H. White, John Ewer

This study identifies CG10738 as the Drosophila EHR, showing its role in ecdysis and its expression in ETH-producing cells and other neuronal targets.

The olfactory organ is a site for neuroendocrine modulation of reproduction in zebrafish

Eugene M Tine, Ingrid Pinto-Borguero, Constanza Aguirre-Campos, P. Marcela Escobar, Ricardo Fuentes, John Ewer, Kathleen E. Whitlock

The paper investigates the role of Gnrh in zebrafish reproduction, showing that waterborne Gnrh modulates the hypothalamic-pituitary axis and that gnrh-r3 knockout leads to infertility.

Timed receptor tyrosine kinase signaling couples the central and a peripheral circadian clock in Drosophila

Javier Cavieres-Lepe, Emad Amini, Maia Zabel, Dick R. Nässel, Ralf Stanewsky, Christian Wegener, John Ewer

The paper identifies receptor tyrosine kinase (RTK) signaling as a mechanism coupling the central and peripheral circadian clocks in Drosophila, showing multiple RTKs contribute to circadian rhythm synchronization.

Extracting temporal relationships between weakly coupled peptidergic and motoneuronal signaling: application to Drosophila ecdysis behavior

Miguel Piñeiro, Wilson Mena, John Ewer, Patricio Orio

The paper develops methods to analyze temporal relationships between peptidergic and motoneuronal activity during Drosophila ecdysis, revealing cross-frequency coupling and identifying a new post-ecdysis phase.
