Inflammatory cytokines induce a reduction in E-cadherin expression and morphological changes in MDCK cells

Area of Science:

• Cell Biology
• Molecular Biology
• Veterinary Medicine

Background:

• Epithelial-mesenchymal transition (EMT) is crucial for development and disease, including cancer metastasis.
• Inflammatory cytokines (TNF-α, IL-6) are known to induce EMT in human cells.
• The effect of inflammatory cytokines on EMT in canine cell lines is not well understood.

Purpose of the Study:

• To investigate the role of transforming growth factor beta (TGF-β), TNF-α, and IL-6 in EMT in Madin-Darby canine kidney (MDCK) cells.
• To determine if inflammatory cytokines can induce EMT-like changes in canine cells.

Main Methods:

• MDCK cells were treated with TGF-β, TNF-α, and IL-6.
• Changes in E-cadherin localization and expression were analyzed.
• Morphological alterations in MDCK cells were observed under cytokine stimulation.

Main Results:

• Persistent stimulation with inflammatory cytokines led to decreased E-cadherin expression and altered localization in MDCK cells.
• Significant morphological changes were observed in MDCK cells following cytokine treatment.
• These findings suggest inflammatory cytokines can influence EMT processes in canine cells.

Conclusions:

• Inflammatory cytokines, including TNF-α and IL-6, can induce EMT-related changes in canine kidney cells.
• Observed morphological changes may indicate late-stage EMT processes.
• Inflammatory cytokines play a potential role in canine EMT.
