Insights

Transforming growth factor-β (TGF-β) signaling is crucial for cell regulation and homeostasis. This study reviews how TGF-β signals are controlled to prevent cellular dysfunction and disease.

Area of Science:

  • Cellular biology
  • Molecular signaling
  • Physiology

Background:

  • Transforming growth factor-β (TGF-β) family signaling regulates vital cellular processes including growth, differentiation, and homeostasis.
  • Dysregulation of TGF-β signaling is implicated in serious health conditions such as congenital disorders, cancer, and fibrosis.
  • TGF-β signal transduction involves receptor-ligand complexes and intracellular Smad molecules, controlling diverse biological activities.

Purpose of the Study:

  • To review recent advancements in understanding the regulatory mechanisms of TGF-β family signaling.
  • To elucidate how TGF-β signals are perturbed and terminated to maintain cellular homeostasis.
  • To provide insights into the control of TGF-β signaling duration and intensity.

Main Methods:

  • Literature review of recent research on TGF-β signaling pathways.
  • Analysis of molecular mechanisms controlling TGF-β signal transduction and termination.
  • Synthesis of current knowledge on homeostasis maintenance through TGF-β signal regulation.

Main Results:

  • TGF-β signaling is tightly regulated to maintain cellular balance.
  • Elaborate mechanisms exist to control the duration and intensity of TGF-β signals.
  • Understanding these regulatory processes is key to addressing diseases linked to TGF-β dysregulation.

Conclusions:

  • Proper regulation of TGF-β signaling is essential for preventing diseases like cancer and fibrosis.
  • Further research into TGF-β signal termination pathways can offer therapeutic targets.
  • Maintaining homeostasis through controlled TGF-β signaling is critical for overall health.

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 are of three kinds RI, RII, and RIII. The RI...
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...
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
Amplifying Signals via Enzymatic Cascade01:22

Amplifying Signals via Enzymatic Cascade

When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
