Insights

Transforming growth factor-beta (TGF-beta) is crucial for cell regulation, embryonic development, and tissue repair. Dysregulation of TGF-beta signaling is linked to human diseases like fibrosis and cancer.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Developmental Biology

Context:

  • Transforming growth factor-beta (TGF-beta) family members are key regulators of fundamental cellular processes.
  • These growth factors influence cell growth, differentiation, extracellular matrix production, cell migration, and embryonic development.
  • TGF-beta's role is critical in inflammation and tissue repair, as evidenced by mouse knock-out studies.

Purpose:

  • To elucidate the multifaceted roles of TGF-beta signaling in biological processes.
  • To highlight the involvement of TGF-beta in the pathogenesis of human diseases, including fibrosis and cancer.
  • To describe the Smad proteins as central mediators of TGF-beta intracellular signal transduction.

Summary:

  • TGF-beta family members are multifunctional peptide growth factors with diverse regulatory functions.
  • Knock-out experiments in mice underscore the importance of TGF-beta in inflammation and tissue repair.
  • TGF-beta signaling is implicated in human diseases such as fibrosis and cancer, potentially exhibiting dual roles in oncogenesis.

Impact:

  • Understanding TGF-beta signaling is vital for comprehending normal development and disease pathogenesis.
  • This knowledge can inform therapeutic strategies for fibrotic conditions and cancers.
  • Elucidation of the Smad pathway provides insights into intracellular signal transmission from TGF-beta receptors to the nucleus.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

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 hydroxylase and factor...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

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...
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...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

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 rapamycin-insensitive companion...
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...
