Board 28 THE EFFECTS OF MSH PROHORMONE ON MELANOPHORE
DARKENING IN ANOLIS CAROLINENSIS.
The chromatophores of teleosts are generally classified into seven categories on the basis of their color: melanophore
(black), erythrophore (red), xanthophore (yellow), cyanophore (blue), leucophore (white), iridophore (iridescent color), and erythro-iridophore (reddish violet) (1-4).
Wales attributed the yellow coloration to a loss of melanophore
control due to disease or parasitism, but was unable to identify any causative agent.
Immature ovaries are whitecoloured with small black dots due to melanophore
cells that, during development, start to proliferate and cover the whole surface, in consequence, the gonads become completely black.
Medaka has four main pigments (melanophore
, iridophore, leucophore, and xanthophore).
Arena is developing a broad pipeline of compounds that act on an important class of drug targets called G protein-coupled receptors, or GPCRs, using its proprietary technologies, including CART (Constitutively Activated Receptor Technology) and Melanophore
. Arena has three internally discovered, clinical-stage product candidates.
Rasquin (1947) examined pigmentation in Astyanax mexicanus raised in total darkness for 2 yr and found the fishes to be depigmented due to a decrease in number of melanophores
and the amount of melanin granules per melanophore
Immature ovaries are white-coloured with small black dots due to melanophore
cells that, during development, start to proliferate and cover the whole surface; as a consequence, the gonads become completely black.
These issued and pending patents are directed to Constitutively Activated Receptor Technology, or CART, Melanophore
technology, chemical compositions of matter, methods of treatment utilizing chemical compositions, or GPCR genes.
macclellandi presents a different pigmentation pattern consisting in large melanophore
groups with a body arrangement that changes from one stage to the next; additionally, from the preflexion stage it develops both the occipital radius and pelvic fins.
A distinctive pattern of melanophore
distribution present on head, body, and fins.
Regulated bidirectional motility of melanophore
pigment granules along microtubules in vitro.
