... related to access of oxygen to the photocytes. The results suggest that the repression model for bioluminescence control can be rejected. An alternative is proposed based on neural upregulation modulating bioluminescence intensity. * Author for correspondence ([email protected]) Competing...

... that the effects of U-73122 are unspecific. Moreover,quantitative assays of labelled IP 3 have shown the absence of IP 3 production when photocytes are stimulated (results not shown),suggesting that bioluminescence control is not mediated by IP 3 production. Conversely, IP 3 involvement in luminescence control...

..., that flashing is controlled by gating oxygen access to the light-emitting cells (photocytes). According to this theory, the dark state represents repression of bioluminescence by limiting oxygen, which is required for bioluminescence; relief from this repression by transiently allowing oxygen access...

...N. De Bremaeker; F. Baguet; J. Mallefet ABSTRACT The effects of catecholamines (dopamine, adrenaline, noradrenaline and its derivatives), 5-hydroxytryptamine and purines (adenosine, ATP and their derivatives) on the acetylcholine-induced luminescence of isolated arms and dissociated photocytes...
