Insights

Thidiazuron (TDZ), a plant growth regulator, was investigated for its anti-metastatic properties in breast cancer. TDZ effectively suppressed cancer cell migration and invasion by inhibiting epithelial-mesenchymal transition (EMT).

Area of Science:

  • Oncology
  • Cell Biology
  • Pharmacology

Background:

  • Breast cancer metastasis remains a significant global health challenge.
  • Existing treatments for metastatic cancer have limited efficacy.
  • Thidiazuron (TDZ), a plant growth regulator, exhibits potential anticancer properties.

Purpose of the Study:

  • To investigate the anti-metastatic effects of TDZ in breast cancer cell lines.
  • To assess TDZ's potential to inhibit epithelial-mesenchymal transition (EMT).
  • To analyze TDZ's impact on key signaling pathways and matrix metalloproteinases (MMPs).

Main Methods:

  • Pretreatment of BEAS-2B and MDA-MB-231 cells with varying concentrations of TDZ.
  • Assessment of cell viability, mammosphere formation, and cell migration.
  • Analysis of NF-κB and PI3K/AKT signaling pathways.
  • Evaluation of MMP and tissue inhibitor of metalloproteinase (TIMP) expression.
  • Investigation of EMT induction in TGF-β/TNF-α-stimulated BEAS-2B cells.

Main Results:

  • TDZ (5-50 μmol) significantly reduced migration and invasion in highly metastatic MDA-MB-231 cells.
  • TDZ downregulated uPAR, uPA, VEGF, and MMP-2/-9 expression.
  • TDZ upregulated TIMP-1/2 expression.
  • TDZ inhibited invasion and EMT in TGF-β/TNF-α-stimulated BEAS-2B cells.

Conclusions:

  • TDZ demonstrates significant anti-metastatic potential in breast cancer models.
  • TDZ effectively inhibits cancer cell invasion and metastasis by suppressing EMT.
  • TDZ represents a promising therapeutic agent for combating breast cancer metastasis.

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...

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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

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...
