Coelenterazine-dependent Bioluminescence in the Cyclopoid Copepod, Triconia conifera.

Species in the cyclopoid copepod Triconia are known to be bioluminescent, emitting blue light by mechanical stimulus. In this study in Triconica conifera, we identified the presence of luciferase activity to coelenterazine, a substrate for the bioluminescence in various marine taxa such as luminous cnidarians, fishes, and crustaceans including calanoid copepods. The molecular size estimated by gel-filtration chromatography and pH dependency of the luciferase activity were similar to those in calanoid copepods.

Vesicular glutamate release is necessary for neural tube formation.

The brain and spinal cord originate from a neural tube that is preceded by a flat structure known as the neural plate during early embryogenesis. In humans, failure of the neural plate to convert into a tube by the fourth week of pregnancy leads to neural tube defects (NTDs), birth defects with serious neurological consequences. The signaling mechanisms governing the process of neural tube morphogenesis are unclear.
