Abstract:
Breast cancer is the major type among the women population globally. The treatment of cancer metastasis has made modest progress due to multiple factors. Thidiazuron (TDZ) is a novel plant growth regulator that has been shown to have anticancer effects. Therefore, we explored the anti-metastatic potentials of TDZ in cell lines by assessing its potential to suppress the epithelial-mesenchymal transition (EMT). We pretreated the BEAS-2B and breast cancer (MDA-MB-231) cells with TDZ and deliberated alteration in a cell viability, mammosphere, migration, NF-кB signalling, PI3K/AKT signalling and matrix metalloproteinase (MMP) expression and analysed the EMT induction by TGF-β/TNF-α-stimulated BEAS-2B cells. Treatment with TDZ (5-50 μmol) diminished the migration and invasion of the extremely metastatic MDA-MB-231 cells. Additionally, TDZ treatment led to down-regulation of uPAR, uPA, VEGF and MMP-2/-9 expression and up-regulation of TIMP-1/2 expression in these cells. Furthermore, TDZ treatment blocked invasion and EMT in non-tumorigenic BEAS-2B epithelial cells stimulated with TGF-β/TNF-α.TDZ prevents EMT and may thus block metastasis of breast cancer cells.
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.
