碩士 === 國立臺灣大學 === 漁業科學研究所 === 86 === The first somite appears at 10 hr post-fertilization during zebrafish
embryonic development. Somites, derived from paraxial mesoderm,
differentiate into muscle, cartilage and dermis in the course of
development. Myosin, one of the main muscular structural proteins,
primarily functions as the source of contraction force for muscle
movement. Approximately 14 classes of myosin molecules have been
identified from diverse organisms. For example, myosin II is consisted
of two identical heavy chains and four different light chain subunits.
A 2 kb cDNA was cloned from agt10 cDNA library, which was
obtained from poly(A)+ mRNA in one-month old zebrafish larvae.
Nucleic acid and deduced amino acid sequence analyses showed that the
2 kb cDNA shared high similarity with that of fast skeletal muscle
myosin heavy chain from carp (Cyprinus carpio). They shared 76%
nucleic acid sequence identity, 83.5 % amino acid sequence identity, and
88% amino acid sequence similarity. The expression of myosin heavy
chain mRNA during zebrafish development was analyzed by Northern
blotting. Expression of a 6.5 kb mRNA was maximal at the time of
hatching and then decreased as the development proceeds, from larval to
adult stage. Whole mount in situ hybridization showed that myosin
heavy chain mRNA were localized at somite region of pharyngula stage
embryos and skeletal muscle region of hatching larvae, at the pectoral
fins of 4-days old hatching larvae. Furthermore, results from whole
mount in situ hybridization also revealed that myosin heavy chain mRNA
were mainly expressed in the fast muscle fibers, which are believed to be
the primary production sites of contraction force of embryos at hatching.
