Insights

Targeting cancer

Area of Science:

  • Oncology
  • Molecular Biology
  • Endocrinology

Background:

  • Insulin-like growth factor 1 receptor (IGF-1R) plays a key role in cancer development.
  • Single-agent targeting of IGF-1R has shown limited clinical efficacy.
  • Complex crosstalk between IGF-1R and other signaling pathways is crucial in tumorigenesis.

Purpose of the Study:

  • To review the crosstalk between IGF-1R, receptor tyrosine kinases (RTKs), and steroid hormone receptors.
  • To discuss therapeutic strategies targeting these crosstalk pathways.
  • To explore future cancer therapeutic potential.

Main Methods:

  • Literature review of signaling pathway interactions.
  • Analysis of therapeutic strategies targeting crosstalk.
  • Evaluation of recent developments in cancer therapy.

Main Results:

  • IGF-1R interacts with RTKs (IR, EGFR, VEGFR, MET, PDGFR, FGFR) and steroid hormone receptors (ERα, ERβ, AR, PR).
  • Crosstalk promotes tumorigenesis and contributes to therapy resistance.
  • Crosstalk-cotargeting strategies show promise in overcoming resistance to conventional therapies.

Conclusions:

  • Crosstalk between IGF-1R, RTKs, and steroid hormone receptors is a significant driver of cancer progression.
  • Crosstalk-cotargeting offers advantages over single-agent therapies.
  • Targeting these complex networks holds potential for novel cancer therapeutics.

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...
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.

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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...
Regulation of Angiogenesis and Blood Supply01:24

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...
