...Aloysius Wong; Lara Donaldson; Maria Teresa Portes; Jörg Eppinger; José A. Feijó; Christoph Gehring ABSTRACT Nitric oxide (NO) is a key signaling molecule that regulates diverse biological processes in both animals and plants, including important roles in male gamete physiology. In plants...

...Sabine Knipp; Gerd Bicker The enteric nervous system (ENS) of insects is a useful model to study cell motility. Using small-molecule compounds to activate or inactivate biosynthetic enzymes, we demonstrate that the gaseous messenger molecules carbon monoxide (CO) and nitric oxide (NO) regulate...

Connolly; Katherine Nash; Aduen Morales-Garcia; Jackson Kirkman-Brown; Steve Publicover Generation of NO by nitric oxide synthase (NOS) is implicated in gamete interaction and fertilisation...

...Anjali K. Nath; Josephine Enciso; Misako Kuniyasu; Xiao-Ying Hao; Joseph A. Madri; Emese Pinter Nitric oxide (NO) has been demonstrated to mediate events during ovulation,pregnancy, blastocyst invasion and preimplantation embryogenesis. However,less is known about the role of NO during...

...Annely Haase; Gerd Bicker The dynamic regulation of nitric oxide synthase (NOS) activity and cGMP levels suggests a functional role in the development of nervous systems. We report evidence for a key role of the NO/cGMP signalling cascade on migration of postmitotic neurons in the enteric nervous...

... gregaria ) where two siblings of pioneer neurons establish the first two axonal pathways to the CNS. Using immunocytochemistry we detected nitric oxide (NO)-induced synthesis of cGMP in the pioneer neurons of the embryonic antenna. A potential source of NO are NADPH-diaphorase-stained epithelial cells...

...David T. Champlin; James W. Truman ABSTRACT Proliferation of neural precursors in the optic lobe of Manduca sexta is controlled by circulating steroids and by local production of nitric oxide (NO). Diaphorase staining, anti-NO synthase (NOS) immunocytochemistry and the NO-indicator, DAF-2, show...

...Y. P. Tao; T. P. Misko; A. C. Howlett; C. Klein ABSTRACT We have previously demonstrated that nitric oxide (NO)- generating compounds inhibit D. discoideum differentiation by preventing the initiation of cAMP pulses (Tao, Y., Howlett, A. and Klein, C. (1996) Cell. Signal . 8, 37-43). In the present...

...James W. Truman; Jan De Vente; Eldon E. Ball ABSTRACT Many developing insect neurones pass through a phase when they respond to nitric oxide (NO) by producing cyclic GMP. Studies on identified grasshopper motoneurones show that this NO sensitivity appears after the growth cone has arrived at its...
