Project description:Background: Maternal iron deficiency (ID) is associated with poor pregnancy and fetal outcomes. The effect is thought to be mediated by the placenta but there is no comprehensive assessment of placental response to maternal ID. Additionally, whether the influence of maternal ID on the placenta differs by fetal sex is unknown. Objectives: Our primary aim was to identify gene and protein signatures of ID mouse placentas at mid-gestation. A secondary objective was to profile the expression of iron genes in mouse placentas across gestation. Methods: We used a real-time PCR based array to determine the mRNA expression of all known iron genes in mouse placentas at embryonic day (E) 12.5, E14.5, E16.5, and E19.5 (n=3 placentas/time point). To determine the effect of maternal ID, we performed RNA sequencing and proteomics in male and female placentas from ID and iron adequate mice at E12.5 (n=8 dams/diet). Results: In female placentas, six genes including transferrin receptor (Tfrc) and solute carrier family 11 member 2 were significantly changed by maternal ID. An additional 154 genes were altered in male ID placentas. Proteomic analysis quantified 7662 proteins in the placenta. Proteins translated from iron responsive element (IRE) containing mRNAs were altered in abundance; ferritin and ferroportin 1 decreased while TFRC increased in ID placenta. Less than 4% of the significantly altered genes in ID placentas occurred both at the transcriptional and translational levels. Conclusions: Our data demonstrate that the impact of maternal ID on placental gene expression in mice is limited in scope and magnitude at mid-gestation. We provide strong evidence for IRE-based transcriptional and translational coordination of iron gene expression in the mouse placenta. Finally, we discover sexually dimorphic effects of maternal ID on placental gene expression, with more genes and pathways altered in male compared with female mouse placentas.

Project description:Microarray analysis of human fetal microglia from the mid-trimester period was performed. DEGs were identified between early and late stages of the mid-trimester gestation. Genes expressed in the human fetal microglia were also compared with mouse microglia core signature.

Project description:MicroRNAs (miRNAs) are critical to proliferation, differentiation, and development. Here, we characterize gene expression in murine Dicer-null adult mesenchymal stem cell lines, a fibroblast cell type. Loss of Dicer leads to de-repression of let-7 targets at levels that exceed 10-100 fold with increases in transcription. Direct and indirect targets of this miRNA belong to a mid-gestation embryonic program that encompasses known oncofetal genes as well as oncogenes not previously associated with an embryonic state. Surprisingly, this mid-gestation program represents a distinct period that occurs between the pluripotent state of the inner cell mass at embryonic day 3.5 and the induction of let-7, upon differentiation, at embryonic day 10.5. Within this mid-gestation program, we characterize the let-7 target Nr6a1, an embryonic transcriptional repressor that regulates gene expression in adult fibroblasts following miRNA loss. In total, let-7 is required for the continual suppression of embryonic gene expression in adult cells, a mechanism that may underlie its tumor suppressive function.
