Summary
Fibroblast growth factor (Fgf) signaling controls placental development. The Ets2 repressor factor (Erf) recruits the Nuclear Receptor Co-Repressor (NCoR1/2) complex to genes, repressing transcription and guiding trophoblast stem cell (TSC) differentiation.
Area of Science:
- Developmental Biology
- Epigenetics
- Molecular Biology
Background:
- Placental development involves complex cell fate decisions driven by signaling pathways.
- Mechanisms translating signaling inputs into gene repression and lineage specification remain poorly understood.
Purpose of the Study:
- To elucidate how signaling cues are converted into repressive mechanisms controlling trophoblast stem cell (TSC) differentiation.
- To investigate the role of the Ets2 repressor factor (Erf) and Nuclear Receptor Co-Repressor (NCoR1/2) complex in placental development.
Main Methods:
- Utilized mouse trophoblast stem cells (TSCs) with Fgf/Erk pathway inhibition.
- Investigated Erf interaction with NCoR1/2 complex using genetic ablation of Erf and Tbl1x.
- Analyzed gene expression and enhancer activity (H3K27ac) of target genes.
Main Results:
- Inhibition of Fgf/Erk pathway in TSCs promotes Erf interaction with NCoR1/2.
- Genetic disruption of Erf or Tbl1x impairs Erf/NCoR1/2 interaction and leads to TSC differentiation defects.
- Erf recruits NCoR1/2 to silence target genes by decommissioning H3K27ac-marked enhancers.
Conclusions:
- The Fgf/Erf/NCoR1/2 axis is a critical repressive mechanism governing TSC fate and placental development.
- This pathway provides a model for understanding Fibroblast growth factor (Fgf)-mediated transcriptional control during development.

7.5K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.3K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

01:21Cell Polarization by Rho Proteins
2.7K
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

01:24Regulation of Angiogenesis and Blood Supply
2.6K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

02:23Master Transcription Regulators
7.0K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
