Behavioral responses to hypoxia and hyperoxia in Drosophila larvae

Atypical soluble guanylyl cyclases mediate behavioral responses to hypoxia in Drosophila larvae

Behavioral responses to hypoxia in Drosophila larvae are mediated by atypical soluble guanylyl cyclases.

The three Drosophila atypical soluble guanylyl cyclases, Gyc-89Da, Gyc-89Db, and Gyc-88E, have been proposed to act as oxygen detectors mediating behavioral responses to hypoxia. Drosophila larvae mutant in any of these subunits were defective in their hypoxia escape response-a rapid cessation of feeding and withdrawal from their food. This response required cGMP and the cyclic nucleotide-gated...

Title: Cardiac responses to hypoxia and reoxygenation in Drosophila Running Title: Cardiac responses to hypoxia

An adequate supply of oxygen is important for the survival of all tissues, but is especially critical for tissues with high energy demands such as the heart. Insufficient tissue oxygenation occurs under a variety of conditions, including high altitude, embryonic and fetal development, inflammation, and thrombotic diseases, often affecting multiple organ systems. Responses and adaptations of the...

Olfactory responses of Drosophila larvae.

We studied complete dose-response curves for 53 odorants in the third instar larvae of Drosophila melanogaster. All odorants, except one, elicited an attraction response. Some odorants also elicited a decrease from their peak response at higher concentrations. This concentration-dependent decrease in olfactory response could be due to either desensitization or repulsion, 2 possibilities that we...
