Analysis illustrates the mechanisms by which Hox genes orchestrate organogenesis
Published in Heart Disease Weekly, October 17th, 2004
According to a study from France, "The segmented Drosophila linear cardiac tube originates from two cell lineages that give rise to the anterior aorta (AA) and the posterior cardiac tube. The three Hox genes of the bithorax complex as well as Antennapedia (Antp) have been shown to be expressed in the posterior cardiac tube, while no Hox gene is expressed in the anterior aorta."
L. Perrin and colleagues of the University of the Mediterranean said of their study, "We show that the cells of the whole tube adopt the anterior aorta identity in the complete absence...
