Shadoo and PrP belongs to the same protein family, whose biological function remains poorly understood. Previous experiments reported potential functional redundancies or antagonisms between these two proteins, depending on the tissue analysed. While knockdown experiments suggested the requirement of Shadoo in the absence of PrP during early mouse embryogenesis, knockout ones, on the contrary, highlighted little impact, if any, of the double-knockout of these two loci. In the present study, we reinvestigated the phenotype associated with the concomitant knockout of these two genes using newly produced FVB/N Sprn knockout mice. In this genetic background, the combined two genes' knockout induces intra-uterine growth retardations, likely resulting from placental failures highlighted by transcriptomic analyses that revealed potential redundant or antagonist roles of these two proteins in different developmental-related pathways. It also induced an increased perinatal-lethality and ascertained the role of these two loci in the lactation process.
