Table 4. Spatial and temporal expression of DMRT2-3-4-5-6-7-8 genes during embryogenesis and in adult animals across different vertebrate species. The order of the indicated tissues in the row correlates with the decreasing level of the detected expression (e.g., the murine DMRT7 at the E14.5 was enriched in ovaries).

Giroud and co-workers found that abortion was frequent in riboflavin deficiency and that monsters often were born (Giroud ). Lepkovsky et had previously showed that riboflavin deficiency in the chick embryo produced a degeneration of the mesonephros and the development of edema and anemia.
