[PMID: 37482155 DOI: 10.1016/j.ijbiomac.2023.125907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 07/04/2023] [Accepted: 07/10/2023] [Indexed: 07/25/2023]
Abstract
Fish skeletal muscle is composed of two anatomically and functionally different fiber layers, white or fast and red or slow muscles. Myosin, the major structural protein of fish skeletal muscle, contains multiple myosin heavy chain (MYH) isoforms involved in the high plasticity of muscle in response to varying functional demands and/or environmental changes. In this study, we comparatively assayed the cellular and ultrastructural feature of white and red skeletal muscles. Then, a total of 28 class II myosin heavy chain genes were identified in by searching the Chinese perch genome database. Among them, 14 genes code for the fast-muscle-type myosin heavy chain, and 7 genes code for the slow-muscle-type myosin heavy chain. Further, the different isoform gene structures, function domains, phylogenetic relations, and muscle-fiber type-specific expression were characterized. This is the first systematic work on the molecular characterization of class II myosin heavy chain isoforms and the differential analysis of their expression in red and white muscle tissues in Chinese perch Siniperca chuatsi. Our work provided valuable information for a better understanding of myh genes and their molecular characteristics, and the correlations of multiple myosin isoforms with potential functions in response to varying functional demands and/or environmental changes.

Lampreys have a single gene cluster for the fast skeletal myosin heavy chain gene family. PLoS One 2013; 8:e85500. [PMID: 24376886 PMCID: PMC3869912 DOI: 10.1371/journal.pone.0085500] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2013] [Accepted: 12/05/2013] [Indexed: 01/13/2023] Open
Abstract
Muscle tissues contain the most classic sarcomeric myosin, called myosin II, which consists of 2 heavy chains (MYHs) and 4 light chains. In the case of humans (tetrapod), a total of 6 fast skeletal-type MYH genes (MYHs) are clustered on a single chromosome. In contrast, torafugu (teleost) contains at least 13 fast skeletal MYHs, which are distributed in 5 genomic regions; the MYHs are clustered in 3 of these regions. In the present study, the evolutionary relationship among fast skeletal MYHs is elucidated by comparing the MYHs of teleosts and tetrapods with those of cyclostome lampreys, one of two groups of extant jawless vertebrates (agnathans). We found that lampreys contain at least 3 fast skeletal MYHs, which are clustered in a head-to-tail manner in a single genomic region. Although there was apparent synteny in the corresponding MYH cluster regions between lampreys and tetrapods, phylogenetic analysis indicated that lamprey and tetrapod MYHs have independently duplicated and diversified. Subsequent transgenic approaches showed that the 5′-flanking sequences of Japanese lamprey fast skeletal MYHs function as a regulatory sequence to drive specific reporter gene expression in the fast skeletal muscle of zebrafish embryos. Although zebrafish MYH promoters showed apparent activity to direct reporter gene expression in myogenic cells derived from mice, promoters from Japanese lamprey MYHs had no activity. These results suggest that the muscle-specific regulatory mechanisms are partially conserved between teleosts and tetrapods but not between cyclostomes and tetrapods, despite the conserved synteny.

Abstract
Three embryonic myosin heavy chain (MYH) genes >> (MYHs) including MYH(emb1), MYH(emb2) and MYH(emb3) and encoding a C-terminal part of MYH were previously cloned and demonstrated to be expressed transiently in this order during development of common carp Cyprinus carpio embryos. The present study determined the full-length cDNA nucleotide sequences encoding the motor domain of the three MYHs, suggesting the implication of loop 1 and loop 2 sequences for the differences in the motor functions. Phylogenetic analysis based on the full-length amino acid sequences showed that MYH(emb1) and MYH(emb2) both belong to the fast types, though clearly differ from fast-type MYHs expressed in adult fast muscle previously reported. In contrast, MYH(emb3) was in a clade containing slow/cardiac type. Whole-mount immunostaining and in situ hybridization showed that the transcripts of the three embryonic MYHs are localized in the same or different cranial muscles of common carp larvae, suggesting that the three MYHs function cooperatively or individually in various cranial muscles.

Abstract
Myosin heavy chain genes (MYHs) are the most important functional domains of myosins, which are highly conserved throughout evolution. The human genome contains 15 MYHs, whereas the corresponding number in teleost appears to be much higher. Although teleosts comprise more than one-half of all vertebrate species, our knowledge of MYHs in teleosts is rather limited. A comprehensive analysis of the torafugu (Takifugu rubripes) genome database enabled us to detect at least 28 MYHs, almost twice as many as in humans. RT-PCR revealed that at least 16 torafugu MYH representatives (5 fast skeletal, 3 cardiac, 2 slow skeletal, 1 superfast, 2 smooth, and 3 nonmuscle types) are actually transcribed. Among these, MYH(M743-2) and MYH(M5) of fast and slow skeletal types, respectively, are expressed during development of torafugu embryos. Syntenic analysis reveals that torafugu fast skeletal MYHs are distributed across five genomic regions, three of which form clusters. Interestingly, while human fast skeletal MYHs form one cluster, its syntenic region in torafugu is duplicated, although each locus contains just a single MYH in torafugu. The results of the syntenic analysis were further confirmed by corresponding analysis of MYHs based on databases from Tetraodon, zebrafish, and medaka genomes. Phylogenetic analysis suggests that fast skeletal MYHs evolved independently in teleosts and tetrapods after fast skeletal MYHs had diverged from four ancestral MYHs.

Abstract
To disclose mechanisms involved in temperature acclimation of fish muscle, we subjected eurythermal fish of medaka Oryzias latipes to cloning of myosin heavy chain genes (MYHs). We cloned cDNAs encoding fast skeletal muscle myosin heavy chain (MYH) isoforms from cDNA libraries of medaka acclimated to 10 and 30 degrees C and observed that different MYH cDNA clones are expressed in the two temperature-acclimated fish. Subsequently, we isolated several overlapping MYH contigs by shotgun cloning strategy from a medaka genomic library. Contig assembly of the complete medaka MYH (mMYH) locus of 219 kbp revealed a cluster of tandemly arrayed 11 mMYHs, in which eight genes are actually transcribed, with the remaining three being pseudogenes. Expression analysis of the transcribed genes revealed that two genes were each highly expressed in medaka acclimated to 10 and 30 degrees C, whereas comparatively lower expression levels of the three genes were exclusively observed in medaka acclimated to 30 degrees C. cDNAs of the remaining genes were too underrepresented in the libraries to determine the expression levels, and the transcripts could only be obtained by reverse transcription-polymerase chain reaction. Deduced amino acid sequences in the loop 1 and loop 2 regions of mMYHs were highly variable, suggesting that these isoforms were functionally different. The present findings consolidate our knowledge on teleost MYH multigene family and would provide further insight into the mechanisms by which expressions of individual MYH molecules are fine-tuned with environmental temperature fluctuations with further functional analysis of the genes concerned.

Gene 2006; 372:82-91.

Abstract
Two types of the fast skeletal myosin heavy chain (MYH) genes were cloned from a genomic DNA library of carp (Cyprinus carpio L.) and named MYH10 and MYH30, which showed the sequence similarity to the MYH cDNAs predominantly expressed in carp acclimated to 10 and 30 degrees C, respectively. The 5'-flanking region of about 3 kbp in size each from MYH10 and MYH30 contained various cis-elements to bind to transcriptional regulatory factors such as MyoD family and myocyte enhancer factor 2 (MEF2) family members. To localize functional regions responsible for the MYH gene expression in a temperature-dependent manner, a series of deletion constructs were prepared from the 5'-flanking region, inserted upstream the luciferase gene in a commercially available plasmid, and injected into the dorsal fast muscle of carp acclimated to 10 and 30 degrees C. The sequence of -1004 to -995 bp with the transcriptional activity in MYH30 was identified as an MEF2 binding site. While the activity given by a sequence of -921 to -824 bp in MYH10 contained only a GATA box, that of the activity of the -1 kbp construct from MYH10 was markedly higher in carp reared at 10 degrees C than fish reared at 30 degrees C. On the other hand, no temperature-dependent expressional regulation was observed for MYH30 even with the full-length construct of -3 kbp. The DNA fragment of -921 to -824 bp in MYH10 and MEF2 binding site in MYH30 interacted with nuclear proteins extracted from carp fast skeletal muscle as revealed by electrophoretic mobility shift assay. The signal intensity of a complex formed between the DNA fragment of MYH10 and nuclear extracts from the 10 degrees C-acclimated carp were higher than those with extracts from the 30 degrees C-acclimated fish. Although MEF2-binding site in MYH30 could form complex with nuclear extracts from the 30 degrees C-acclimated carp, the same or stronger signals were detected in complex formed with extracts from the 10 degrees C-acclimated fish.

Abstract
Myosin is a highly conserved, ubiquitous actin-based molecular motor that is distributed as diverse as from prokaryotes to mammalian tissues. Among various types in the myosin family proteins, class II, also called sarcomeric, myosin is a classical, conventional molecule that has been extensively studies on its functional and structural properties. It consists of two heavy chains (MYH) of about 200 kDa and four light chains of about 20 kDa. The exon-intron organization was determined for the major subunit of MYH, which contains ATP-hydrolysis and actin-binding sites, from torafugu (tiger pufferfish) Takifugu rubripes fast skeletal muscles. Comprehensive investigation for fast skeletal MYHs based on the fugu (torafugu) genome database and subsequent construction of their physical map revealed that torafugu contains at least 8 putative skeletal MYHs. Furthermore, genomic structural analysis revealed that skeletal MYHs are not clustered in a single locus, but rather spread to at least four loci, with two of them locating at the mammalian syntenic regions. Such arrangement of torafugu MYHs are in a marked contrast to mammalian fast skeletal MYHs that are clustered in a single locus. These data suggest that an ancient segmental duplication or whole-genome duplication occurred in fish lineage as in many other reported torafugu genes.
