...Hong Duan; Cheng Zhang; Jianming Chen; Helen Sink; Erich Frei; Markus Noll The Pax gene Pox meso ( Poxm ) was the first and so far only gene whose initial expression was shown to occur specifically in the anlage of the somatic mesoderm, yet its role in somatic myogenesis remained unknown. Here we...

... suggests that this subfamily of Pax genes has conserved roles in regional specification of the brain. Comparison with expression of ascidian Otx ( Hroth ) and a Hox gene ( HrHox1 ) by double-staining in situ hybridizations indicate that the ascidian brain region can be subdivided into three regions...
