“…It is preferable to conduct functional analysis of the regulatory elements of newly isolated genes in vivo rather than in vitro. In zebrafish, transgenes containing an endogenous promoter and the green fluorescent protein (GFP) gene have been used to map the cisacting elements of the promoter (Chen et al, 2001;Drivenes et al, 2000;Meng et al, 1997Meng et al, , 1999. They also have been used to target gene expression in specific tissues (Higashijima et al, 1997(Higashijima et al, , 2000Ju et al, 1999;Long et al, 1997).…”

“…Adaxial cells have a distinct cuboidal morphology and express the myogenic basic helix-loop-helix transcription factors myf5 and myod, followed by slow myosin heavy chain (MyHC) (Chen et al, 2001;Coutelle et al, 2001;Devoto et al, 1996;Weinberg et al, 1996). Subsequently, as somite borders form, myf5 and myod mark a distinct population of cells in the lateral somite (Chen et al, 2001;Coutelle et al, 2001;Weinberg et al, 1996). The fate of the medial and lateral myogenic cells is known: medial adaxial cells form slow muscle and most migrate laterally to generate the superficial slow muscle fibres that lie within the somite under the In tetrapod phylogeny, the dramatic modifications of the trunk have received less attention than the more obvious evolution of limbs.…”

Hedgehog regulation of superficial slow muscle fibres inXenopusand the evolution of tetrapod trunk myogenesis

In tetrapod phylogeny, the dramatic modifications of the trunk have received less attention than the more obvious evolution of limbs. In somites,several waves of muscle precursors are induced by signals from nearby tissues. In both amniotes and fish, the earliest myogenesis requires secreted signals from the ventral midline carried by Hedgehog (Hh) proteins. To determine if this similarity represents evolutionary homology, we have examined myogenesis in Xenopus laevis, the major species from which insight into vertebrate mesoderm patterning has been derived. Xenopus embryos form two distinct kinds of muscle cells analogous to the superficial slow and medial fast muscle fibres of zebrafish. As in zebrafish, Hh signalling is required for XMyf5 expression and generation of a first wave of early superficial slow muscle fibres in tail somites. Thus, Hh-dependent adaxial myogenesis is the likely ancestral condition of teleosts, amphibia and amniotes. Our evidence suggests that midline-derived cells migrate to the lateral somite surface and generate superficial slow muscle. This cell re-orientation contributes to the apparent rotation of Xenopussomites. Xenopus myogenesis in the trunk differs from that in the tail. In the trunk, the first wave of superficial slow fibres is missing,suggesting that significant adaptation of the ancestral myogenic programme occurred during tetrapod trunk evolution. Although notochord is required for early medial XMyf5 expression, Hh signalling fails to drive these cells to slow myogenesis. Later, both trunk and tail somites develop a second wave of Hh-independent slow fibres. These fibres probably derive from an outer cell layer expressing the myogenic determination genes XMyf5, XMyoD and Pax3 in a pattern reminiscent of amniote dermomyotome. Thus, Xenopus somites have characteristics in common with both fish and amniotes that shed light on the evolution of somite differentiation. We propose a model for the evolutionary adaptation of myogenesis in the transition from fish to tetrapod trunk.

“…To study the regulation of AmphiMyoD gene expression and to determine if AmphiMyoD promoter could direct gene expression in muscle cells, we used zebrafish embryos as an alternative system to test if the AmphiMyoD promoter could direct expression of reporter gene, such as GFP, in muscle cells. Zebrafish embryos have been used successfully as an in vivo assay system for analysing the regulation of muscle specific gene expression (Chen et al 2001;Tan & Du 2002;Du et al 2003).…”

Vertebrate MyoD family of transcription factors contains four members including MyoD, Myf5, Myogenin and MRF4. These myogenic regulatory factors (MRFs) play key roles in regulating skeletal muscle development and growth. Evolutionary analysis suggests that the four vertebrate MRF genes were derived by gene duplications from a single ancestral gene during chordate evolution. Better understanding of the structure and regulation of MyoD expression in amphioxus Branchiostoma belcheri may provide insight into the evolutionary history of myogenic gene duplications because of the unique position of amphioxus in evolution. We report here that isolation and characterization of a new MyoD gene, AmphiMyoD, in B. belcheri. Sequence analysis revealed that the AmphiMyoD is more closely related to myogenic transcription factors in invertebrates and vertebrates compared with the previously identified three MyoD like genes in amphioxus, suggesting that the AmphiMyoD might be the closest relative of the ancestral myogenic gene. To determine if the AmphiMyoD gene promoter controls muscle-specific expression, the AmphiMyoD promoter was linked with the green fluorescence protein (GFP) reporter and the construct was microinjected into zebrafish embryos for transient expression assay. AmphiMyoD promoter directed skeletal muscle-specific GFP expression in zebrafish embryos. In addition, it also drove GFP expression in cardiac muscles of the injected embryos, but not in other non-muscle tissues. These data demonstrated that the AmphiMyoD promoter contained regulatory elements for skeletal and cardiac muscle-specific expression. Moreover, the regulatory element(s) could function across species.
