Genes expressed in neurons of adult male Drosophila

Article Abstract:

Molecular biological techniques were performed to study roX1 and roX2 Drosophila genes, the expression of which in the adult fly is restricted to the neurons of the males. The two genes were found to be physically linked to female-specific genes that encode ovarian proteins. It was also demonstrated that the male-specific transcripts are positively regulated by the dosage compensation pathway in an all-or-none mode. The findings further indicated that X-linked, male-specific, noncoding RNAs can regulate the expression of linked genes that are expressed only in the females.

Remote control of behavior through genetically targeted photostimulation of Neurons

Article Abstract:

Optically gated ion channels were expressed in circumscribed groups of neurons in the Drosophila CNS so that broad illumination of flies evoked action potentials only in genetically designated target cells. Flies harboring the 'phototriggers' in different sets of neurons responded to laser light with behaviors specific to the sites of phototrigger expression.

New "hogs" in Hedgehog transport and signal reception

Article Abstract:

Interference hedgehog (ihog) and Boi in he fruit fly Drosophila and its mammalian homologs Boc and Cdo are transmembrane proteins that interact with Hedgehog (Hh). These findings raise new questions about the physical composition of Hh receptors, and how distinct responses to a single signal could be achieved.
