Nevertheless, the canine placenta is highly responsive to steroids, and withdrawal of progesterone (P4) affects the feto-matemal unit, initializing the parturition cascade. Similar effects can be observed during antigestagen-induced abortion. Here, aiming to provide new insights into mechanisms involved in the termination of canine pregnancy, next generation sequencing (NGS, RNA-seq) was applied. Placental transcriptomes derived from natural prepartum and antigestagen-induced abortions were analyzed and compared with fully developed mid-gestation placentas. The contrast "prepartum luteolysis over mid-gestation" revealed 1973 differentially expressed genes (DEG). Terms associated with apoptosis, impairment of vascular function and activation of signaling of several cytokines (e.g., IL-8, IL-3, TGF-beta) were over-represented at natural luteolysis. When compared with mid-term, antigestagen treatment revealed 135 highly regulated DEG that were involved in the induced luteolysis and showed similar associations with functional terms and expression patterns as during natural luteolysis. The contrast "antigestagen-induced luteolysis over prepartum luteolysis" revealed that, although similar changes occur in both conditions, they are more pronounced during natural prepartum. Among P4-regulated DEG were those related to immune system and cortisol metabolism. It appears that, besides inducing placental PGF2 alpha output, both natural and induced P4 withdrawal is associated with disruption of the feto-matemal interface, leading to impaired vascular functions, apoptosis and controlled modulation of the immune response. The time-related maturation of the feto-maternal interface needs to be considered because it may be clinically relevant.
