Insights

The transforming growth factor-beta (TGF-β) and phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) pathways collaborate in cancer progression. Dual targeting of these signaling pathways offers a promising strategy for cancer treatment.

Area of Science:

  • Cellular Biology
  • Molecular Oncology
  • Cancer Signaling

Background:

  • Transforming growth factor-beta (TGF-β) exhibits dual roles in cancer, acting cytostatically in early stages and promoting oncogenesis in advanced cancers.
  • Phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) signaling promotes cell survival and tumor formation.
  • Initially viewed as linear and potentially opposing, the TGF-β receptor and PI3K/AKT pathways are now understood to have complex interactions.

Purpose of the Study:

  • To explore the intricate crosstalk and collaborative signaling between the TGF-β and PI3K/AKT pathways.
  • To provide a rationale for investigating dual-targeting strategies in cancer therapy.

Main Methods:

  • Review and synthesis of existing literature on TGF-β and PI3K/AKT signaling.
  • Analysis of experimental evidence detailing pathway interactions and their roles in cancer.

Main Results:

  • Emerging evidence reveals complex signal integration and collaboration between TGF-β and PI3K/AKT pathways.
  • These pathways, once thought to counteract each other, actively cooperate in driving cancer progression.

Conclusions:

  • The intricate interplay between TGF-β and PI3K/AKT signaling is crucial for cancer development.
  • Targeting both pathways simultaneously presents a viable therapeutic approach for combating cancer.

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...

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...

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.

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...

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...
