Beyond dictating the energetic state and furnishing molecular building blocks, cellular metabolism is linked to signal transduction and the stress response. A gestational "metabolic clock" has been proposed to provide insight into pregnancy outcomes, but only limited resolution of the changing placental metabolome has been available through studies of human and monkey tissues. Here we analyzed the placenta metabolome in wild-type mice every 24 hours during the final one-third of pregnancy. Among other changes, there was a notable decline in NAD+ precursors approaching the final day of gestation.'), ('STUDY_SUMMARY', 'Metabolism in the mature placenta is dynamic in response to a changing environment as well as evolving fetal needs.
