Abstract
Several sarcomeric myosin heavy chains (MYHs) were cloned from embryos and larvae of medaka Oryzias latipes. Three genes encoding medaka MYHs (mMYHs) predominantly expressed in embryos (mMYH(emb1)) and larvae (mMYH(L1) and mMYH(L2)), all belonged to fast skeletal MYHs, showing spatiotemporally different expression patterns during development. Besides these mMYHs, a few novel mMYHs were cloned from embryos and larvae at hatching. Whereas mMYH(emb2), mMYH(emb3), and mMYH(L3) belonged to fast skeletal MYH, mMYH(C1) and mMYH(C2) did to slow/cardiac MYH. mMYH(emb1) was expressed ahead of mMYH(L1) and mMYH(L2). In situ hybridization analysis demonstrated that the transcripts of mMYH(emb1) and mMYH(C1) were located in the horizontal myoseptum, whereas those of mMYH(L1) and mMYH(L2) in the inner part of myotomes and pharyngeal muscles, and those of mMYH(C2) in the heart rudiment. In silico cloning based on the medaka genome database showed another mMYHs of the slow/cardiac types, mMYH(C3) and mMYH(C4).
