Insights

Platelet-derived growth factors (PDGFs) and their receptors (PDGFRs) drive breast cancer growth and metastasis. Targeting this PDGF-PDGFR signaling pathway shows promise for new breast cancer therapies and biomarkers.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Platelet-derived growth factors (PDGFs) and their receptors (PDGFRα/β) are crucial in breast cancer progression and metastasis.
  • PDGF-PDGFR signaling influences epithelial-to-mesenchymal transition, cancer stem cells, desmoplasia, angiogenesis, and immune responses.

Purpose of the Study:

  • To review current evidence on PDGF and PDGFR expression, functions, and prognostic value in breast cancer.
  • To evaluate therapeutic strategies targeting the PDGF-PDGFR axis, particularly small molecule inhibitors.
  • To identify future research directions for targeting this pathway in breast cancer.

Main Methods:

  • Literature review of studies on PDGF ligand and PDGFR expression patterns.
  • Analysis of oncogenic functions and prognostic significance of PDGF-PDGFR signaling.
  • Evaluation of preclinical and clinical data for therapeutic interventions targeting PDGF-PDGFR.

Main Results:

  • Distinct oncogenic roles for PDGFA, PDGFB, PD সার্বিক, and PDGFD in breast cancer, including brain metastasis and fibroblast activation.
  • High expression of PDGFA, PDGFB, PDGFC, and stromal PDGFRβ correlates with poor patient survival, indicating biomarker potential.
  • Targeting the PDGF-PDGFR axis with inhibitors shows preclinical promise but limited clinical success.

Conclusions:

  • PDGF-PDGFR signaling is a significant driver of breast cancer progression and metastasis.
  • Further research is needed to develop selective inhibitors and utilize PDGF-PDGFR components for patient stratification and combination immunotherapies.

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...
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.

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...
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...
