7925028-0	1994	Exposure to retinoic acid before or after the onset of somitogenesis reveals separate effects on rhombomeric segmentation and 3" HoxB gene expression domains.	Tretinoin	12-25	homeobox B cluster	Mus musculus	129-133	
7925028-3	1994	In contrast, exposure to RA at early somite stages results in near-normal rhombomeric segmentation; rhombomeric gene expression domains indicate that only rhombomere 2 has changed its genetic identity to that of rhombomere 4, the other preotic segments showing normal expression patterns for HoxB genes and Krox-20.

7925028-4	1994	The results indicate that RA has separable effects (1) on the genes mediating the process of rhombomeric segmentation per se, such as Krox-20, and (2) on the genes that influence the nature of the structures that subsequently develop from the individual rhombomeres, such as the Hox genes.
