Vertebrate somitogenesis comprises the generation of a temporal periodicity, the establishment of anteroposterior compartment identity, and the translation of the temporal periodicity into the metameric pattern of somites. Molecular players at each of thes ...
Mammalian CBFB encodes a transcription factor (CBFβ) that in combination with CBFα2 binds to specific DNA sequences and regulates expression of a number of hematopoietic genes.CBFB is associated with human leukemias through a chromosome 16 inversion and is ...
During development, Hox gene transcription is activated in presomitic mesoderm with a time sequence that follows the order of the genes along the chromosome. Here, we show that Hoxd1 and other Hox genes display dynamic stripes of expression within presomit ...
It has been shown by using the quail/chick chimera system that Hox gene expression in the hindbrain is influenced by positional signals arising from the environment. In order to decipher the pathway that leads to Hox gene induction, we have investigated wh ...
It has been previously shown that Hox gene expression in the rhombencephalon is controlled by environmental cues. Thus posterior transposition of anterior rhombomeres to the r7/8 level results in the activation of Hox genes of the four first paralog groups ...
The products of Hox-4 genes appear to encode position in developing vertebrate limbs. In chick embryos, a number of different signalling regions when grafted to wing buds lead to duplicated digit patterns. We grafted tissue from the equivalent regions in m ...
Pattern formation in animal development requires that genes be expressed differentially according to position in the sheets of cells that make up the early embryo. The homoeobox-containing genes of Drosophila are control genes active both in the establishm ...
