Abstract The amino-acid sequences of the T-domain region of the Tbx4 gene, which is required for hindlimb development, are 100% identical in humans and mice. Cetaceans have lost most of their hindlimb structure, although hindlimb buds are present in very early cetacean embryos. To examine whether the Tbx4 gene has the same function in cetaceans as in other mammals, we analyzed Tbx4 sequences from cetaceans, dugong, artiodactyls and marine carnivores. A total of 39 primers were designed using…

TBX4 mutations (small patella syndrome) are associated with childhood-onset pulmonary arterial hypertension

Data indicate thatTBX4 mutations are associated with childhood-onset PAH, but that the prevalence of PAH in adult TBX4 mutation carriers is low.

TBX4 mutations are associated with childhood-onset PAH, but that the prevalence of PAH in adult TBX4 mutation carriers is low.


Some species of otters have been much more studied than others. A particular challenge in the management and conservation of otters worldwide is that some of the lesser-known species are also among

Mammalian gene evolution: Nucleotide sequence divergence between mouse and rat

Several factors suggest that synonymous codon usage in rodent genes is not subject to selection, and rates of synonymous and nonsynonymous substitution are correlated, apparently because of an excess of substitutions involving adjacent pairs of nucleotides.

Expression of the T‐box family genes, Tbx1–Tbx5, during early mouse development

Examining the expression of 5 of these genes, Tbx1–Tbx5, across a wide range of embryonic stages from blastocyst through gastrulation and early organogenesis by in situ hybridization of wholemounts and tissue sections shows a good indication that the T‐box family of genes has important roles in inductive interactions in many stages of mammalian embryogenesis.

Virtual cloning and physical mapping of a human T-box gene, TBX4.

The Tbx2/3/4/5 subfamily is one of the largest subgroupings within the T-box gene family, the members of which encode developmentally critical transcription factors. TBX4, a human member of the

Crystallographic structure of the T domain–DNA complex of the Brachyury transcription factor

The structure of this T domain complex with DNA reveals a new way in which a protein can recognize DNA, as well as revealing a new type of specific DNA contact.

Phylogenetic relationships among cetartiodactyls based on insertions of short and long interpersed elements: hippopotamuses are the closest extant relatives of whales.

It is concluded that cetaceans evolved from an immediate artiodactyl, not mesonychian, ancestor, thereby shedding light on the origin of whales.

The number of nucleotides required to determine the branching order of three species, with special reference to the human-chimpanzee-gorilla divergence

The probability of obtaining the correct tree (topology) from nucleotide sequence data is evaluated using models of evolutionary trees that are close to the tree of mitochondrial DNAs from human, chimpanzee, gorilla, orangutan, and gibbon.

Synonymous and nonsynonymous rate variation in nuclear genes of mammals

It is found that at 22 of the 48 nuclear loci examined, the nonsynonymous/synonymous rate ratio varies significantly across branches of the tree, which provides strong evidence against a strictly neutral model of molecular evolution.

Hox genes and the evolution of vertebrate axial morphology.

A comparative study of the developmental patterns of homeobox gene expression and developmental morphology between animals that have homologous regulatory genes but different morphologies, which contributes a mechanistic level to the assumed homology of these regions in vertebrates.

Pattern of nucleotide substitution at major histocompatibility complex class I loci reveals overdominant selection

Examination of the pattern of nucleotide substitution between polymorphic alleles in the region of the antigen recognition site (ARS) indicates that in ARS the rate of nonsynonymous substitution is significantly higher than that of synonymous substitution in both humans and mice, whereas in other regions the reverse is true.
