Cloning and Characterization of Integrin α Subunits from the Solitary Ascidian, Halocynthia roretzi1
TLDR
Observations strongly suggest that αHr1 constitutes an integrin molecule on the hemocytes of H. roretzi that functions as an ancestral form of CR3 and CR4 and mediates phagocytosis in the primitive complement system of the ascidian. Expand
Explosive speciation of Takifugu: another use of fugu as a model system for evolutionary biology.
TLDR
The results of the present study strongly suggest that Takifugu species are strong candidates as a model system for evolutionary studies of speciation mechanisms in marine environments where few such organisms are available. Expand
Evolution of the initiating enzymes of the complement system
TLDR
Phylogenetic studies indicate that one arose by retrotransposition early in vertebrate evolution, supporting the idea that the lectin branch of the complement cascade arose earlier than the 'classical' pathway. Expand
Blending of animal colour patterns by hybridization
TLDR
It is shown that complex and camouflaged animal markings can be formed by the 'blending' of simple colour patterns, suggesting an unexplored evolutionary process by means of 'pattern blending', as one of the possible mechanisms underlying colour pattern diversity and hybrid speciation. Expand
Characterization of novel ascidian β integrins as primitive complement receptor subunits
TLDR
Observations showed that αHr1, and possibly βHr2 too, binds to αhr1 to comprise integrin molecules on ascidian hemocytes, which act as ancestral forms of complement receptors in the primitive complement system of ascidians. Expand
Cloning and characterization of integrin alpha subunits from the solitary ascidian, Halocynthia roretzi.
TLDR
Observations strongly suggest that alpha(Hr1) constitutes an integrin molecule on the hemocytes of H. roretzi that functions as an ancestral form of CR3 and CR4 and mediates phagocytosis in the primitive complement system of the ascidian. Expand
Shh signaling is essential for rugae morphogenesis in mice
TLDR
It is shown that Sostdc1, a secreted inhibitor of the Wnt pathway, is a downstream target of Shh and hypothesize that the interaction of Wnt, ShH and SostDC1 is a pivotal mechanism controlling the spatial patterning of palatal rugae. Expand
Comparative transcriptome analysis of trout skin pigment cells
TLDR
The results indicate that the maintenance of different pigment patterns in trout is dependent upon specific communication—involving gap junctions, tight junctions and ion channels—between chromatophores present in differentially pigmented skin regions. Expand

TLDR
Analysis of skin patterns of 18,114 fish species found strong mechanistic associations between camouflaged labyrinthine patterns and simple spot motifs, showing remarkable consistency with the pattern blending hypothesis. Expand
