Project description:Establishment of the hemochorial placentation site requires the exodus of trophoblast cells from the placenta and their transformative actions on the uterine vasculature, which is a critical but poorly understood developmental process. CBP/p300-interacting transactivator with glutamic acid/aspartic acid-rich carboxyl terminal domain 2 (CITED2) is a member of the CITED protein family of co-regulators and has been shown to possess roles in embryogenesis, including placenta development. We examined the involvement of CITED2 in the rat, which exhibits deep hemochorial placentation, a feature it shares with the human. CITED2 is distinctively expressed in the junctional zone compartment of the rat placentation site and in intrauterine invasive trophoblast cells. Homozygous disruption of the rat Cited2 locus resulted in placental and fetal growth restriction and abnormalities in heart and lung development, which are also characteristic of the CITED deficient mouse model. However, other features of the mouse Cited2 null phenotype, including exencephaly, adrenal gland agenesis, and prenatal lethality were not associated with CITED2 deficiency in the rat. Trophoblast-specific lentiviral CITED2 knockdown in the rat yielded a growth arrested placental phenotype. Smaller Cited2 null placentas were associated with a growth restricted junctional zone and coincided with a delay in intrauterine trophoblast cell invasion. Invasive trophoblast cells arise from the junctional zone. Transcriptomes of the junctional zone, the invasive trophoblast cell lineage, and differentiating trophoblast stem cells were affected by CITED2 disruption, as were placental adaptations to hypoxia and exposure to viral mimetics. Evidence for the conservation of CITED2 expression in human placental tissue and conserved actions in invasive/extravillous trophoblast cell development were demonstrated. We conclude that CITED2 is a conserved regulator of deep hemochorial placentation.

Project description:CB CD34+ cells were were transduced with control (tNGFR) or CITED2 overexpression lentivectors, or control (shSCR) or shRNA CITED2 lentivectors and mRNA was isolated in order to investigate global gene expression changes upon perturbation of CITED2. CB CD34+ cells were isolated by Miltenyi miniMACS column. Cells were prestimulated in HPGM with 100 ng/ml KITL, FLT3L and TPO for 12 hrs. Cells were transduced with control (tNGFR) or CITED2 overexpression lentivectors, or control (shSCR) shRNA CITED2 lentivectors, in three rounds over 48 hrs. Transduced cells were sorted after which RNA was isolated for Illumina beadhchip arrays HT12 v4.

Project description:We had previously discovered that the transcription factor OVO-like 1 (OVOL1) was highly induced during trophoblast differentiation. In this study, we used an lentiviral shRNA strategy to decrease OVOL1 expression in BeWo trophoblast cells. Control cells were transduced with shRNAs targeting no known mammalian transcript (shCont). Following stimulation of differentiation (48h exposure to 8-bromo-cyclic adenosine monophosphate), a RNA-seq approach was used to determine global transcript differences in OVOL1-knockdown cells compared to control cells.
