Insights

Fibroblast growth factor (FGF) signaling regulates biological processes but its impairment causes diseases. This review highlights anosmin-1, FLRT3, and Sef proteins that modulate FGF signaling, impacting human health.

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Developmental Biology

Background:

  • Fibroblast growth factor (FGF) signaling is crucial for numerous biological functions.
  • Dysregulation of FGF signaling is linked to human diseases, including developmental disorders and cancer.

Purpose of the Study:

  • To review the positive and negative modulators of FGF signaling.
  • To examine the regulatory roles of anosmin-1, fibronectin-leucine-rich transmembrane protein 3 (FLRT3), and similar expression to FGF (Sef).
  • To explore the implications of these regulators in human diseases.

Main Methods:

  • Literature review of recent findings on FGF signaling modulators.
  • Analysis of protein interactions and regulatory mechanisms.
  • Cross-species comparison of FGF pathway regulation.

Main Results:

  • Anosmin-1, FLRT3, and Sef are key protein regulators of FGF signaling.
  • These proteins modulate FGF activity at multiple distinct levels.
  • The identified regulators play significant roles across different species.

Conclusions:

  • Understanding FGF signaling modulation is vital for comprehending its role in health and disease.
  • Anosmin-1, FLRT3, and Sef represent important targets for therapeutic intervention.
  • Further research into these regulators can illuminate disease mechanisms and potential treatments.

Regulation of Angiogenesis and Blood Supply

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...

Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

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...

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

GTPases and their Regulation02:14

GTPases and their Regulation

Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins,...
