TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

8.3K
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...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

3.0K
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...

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

3.2K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.9K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

4.6K
The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Cell Polarization by Rho Proteins01:21

Cell Polarization by Rho Proteins

3.2K
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,...

Summary

Bone morphogenetic protein 2 (BMP2) is crucial for early pregnancy success. Lower BMP2 levels are linked to early pregnancy loss, but BMP2 promotes embryo development and trophoblast invasion, offering potential therapeutic targets.

Area of Science:

  • Reproductive Biology
  • Developmental Biology
  • Genetics

Background:

  • Embryo implantation and trophoblast invasion are critical for establishing pregnancy.
  • Improper trophoblast function can lead to early pregnancy loss (EPL).
  • Bone morphogenetic protein 2 (BMP2) is implicated in early pregnancy.

Purpose of the Study:

  • To investigate the role of BMP2 in early pregnancy and its association with early pregnancy loss.
  • To elucidate the molecular mechanisms by which BMP2 influences trophoblast differentiation and invasion.

Main Methods:

  • Clinical data analysis of serum BMP2 levels in early pregnancy.
  • In vitro studies using human and mouse trophoblast cells.
  • In vivo studies in mice to assess the effects of exogenous BMP2.
  • Molecular analyses including gene and microRNA expression profiling.

Main Results:

  • Serum BMP2 levels are elevated in the first trimester and lower in women with EPL.
  • BMP2 is expressed in human and mouse oocytes and early embryos.
  • Exogenous BMP2 enhances mouse blastocyst formation and hatching.
  • BMP2 upregulates lncRNA NR026833.1, promoting SNAIL expression via miR-502-5p, which induces MMP2 and enhances trophoblast cell invasion.
  • BMP2 promotes invasive trophoblast differentiation in mouse stem cells.

Conclusions:

  • BMP2 plays a significant role in promoting embryonic development and placental development.
  • BMP2 facilitates trophoblast invasion and differentiation, crucial for successful pregnancy.
  • Findings suggest BMP2 as a potential therapeutic target for pregnancy complications like EPL.
