A CALCIUM-DEPENDENT NITRIC-OXIDE SYNTHASE AND NMDA R1 GLUTAMATE-RECEPTOR IN THE INK GLAND OF SEPIA-OFFICINALIS - A HINT TO A REGULATORY ROLE OF NITRIC-OXIDE IN MELANOGENESIS
A. Palumbo et al., A CALCIUM-DEPENDENT NITRIC-OXIDE SYNTHASE AND NMDA R1 GLUTAMATE-RECEPTOR IN THE INK GLAND OF SEPIA-OFFICINALIS - A HINT TO A REGULATORY ROLE OF NITRIC-OXIDE IN MELANOGENESIS, Biochemical and biophysical research communications, 235(2), 1997, pp. 429-432
Histochemical, immunohistochemical, and biochemical evidence is report
ed showing that the ink gland of the cuttlefish Sepia officinalis cont
ains a calcium-dependent isoform of nitric oxide synthase as well as a
n NMDA R1 receptor subunit localized for the most part in the immature
inner cells of the epithelial layer of the gland. These results may b
e taken to implicate a hitherto unrecognized regulatory role of the gl
utamate-nitric oxide pathway in the maturation and metabolic activity
of melanin-producing cells in the cephalopod defense system. (C) 1997
