Open Accesshoxc12/c13 as key regulators for rebooting the developmental program in Xenopus limb regeneration
During organ regeneration, after the initial responses to injury, gene expression patterns similar to those in normal development are reestablished during subsequent morphogenesis phases. This supports the ide...

Open AccessIdentification of tumor-related genes via RNA sequencing of tumor tissues in Xenopus tropicalis
Cancer treatment is still challenging because the disease is often caused by multiple mutations. Although genomic studies have identified many oncogenes and tumor suppressor genes, gene sets involved in tumori...

Open AccessAir–breathing behavior underlies the cell death in limbs of Rana pirica tadpoles
Amphibians shape their limbs by differential outgrowth of digits and interdigital regions. In contrast, amniotes employ cell death, an additional developmental system, to determine the final shape of limbs. Pr...

Open AccessComparative analysis demonstrates cell type-specific conservation of SOX9 targets between mouse and chicken
SRY (sex-determining region Y)-box 9 (SOX9) is a transcription factor regulating both chondrogenesis and sex determination. Among vertebrates, SOX9’s functions in chondrogenesis are well conserved, while they ...

A Tanganyikan cichlid Neolamprologus mustax selectively exploits territories of another cichlid Variabilichromis moorii due to its inter-individual variation in aggression
Animals in a population consistently differ from one another in behavioural types over time and this difference can affect intra- and interspecific relationships. However, empirical studies about roles of beha...

Open AccessGenome evolution in the allotetraploid frog Xenopus laevis
To explore the origins and consequences of tetraploidy in the African clawed frog, we sequenced the Xenopus laevis genome and compared it to the related diploid X. tropicalis genome. We characterize the allotetra...

Open AccessSix1 is a key regulator of the developmental and evolutionary architecture of sensory neurons in craniates
Various senses and sensory nerve architectures of animals have evolved during adaptation to exploit diverse environments. In craniates, the trunk sensory system has evolved from simple mechanosensory neurons i...

Differential Use of Paralogous Genes via Evolution of Cis-Regulatory Elements for Divergent Expression Specificities
Recent accumulation of genome sequences indicates that vertebrate genomes retained many duplicate genes, called paralogues, after whole-genome duplications (WGDs) occurring in the early stages of chordate evol...

Open AccessEvolution of a tissue-specific silencer underlies divergence in the expression of pax2 and pax8 paralogues
Recent studies underscore a role for the differential degeneration of enhancers in the evolutionary diversification of paralogue expression. However, no one has reported evidence for the involvement of innovat...

Comparative Genomics-Based Identification and Analysis of Cis-Regulatory Elements
Identification of cis-regulatory elements, such as enhancers and promoters, is very important not only for analysis of gene regulatory networks but also as a tool for targeted gene expression experiments. In t...

Increased energy investment in testes following territory acquisition in a maternal mouthbrooding cichlid
Underwater observations conducted in Lake Tanganyika showed that males of a maternal mouthbrooding cichlid, Petrochromis fasciolatus, defended a mating territory for at least several months, but left at approxima...

Farming-out of offspring is a predominantly male tactics in a biparental mouthbrooding cichlid Perrisodus mircolepis
Intraspecific brood-mixing of a Tanganyikan biparental cichlid fish Perissodus microlepis has been attributed to farming-out, a behaviour in which a parent transport some or all of their free-swimming young in th...
