Snail plays an oncogenic role in glioblastoma by promoting epithelial mesenchymal transition

Area of Science:

• Oncology
• Molecular Biology
• Cell Biology

Background:

• Glioblastoma presents poor patient outcomes, necessitating research into progression factors.
• The Snail gene's role in glioblastoma progression is not fully understood, despite its known involvement in epithelial mesenchymal transition (EMT) in other cancers.

Purpose of the Study:

• To investigate the role of the Snail gene in glioblastoma progression.
• To determine if Snail influences glioblastoma cell proliferation, viability, migration, and invasion.

Main Methods:

• Utilized small interfering RNA (siRNA) to reduce Snail gene expression in three glioblastoma cell lines (KNS42, U87, U373).
• Assessed changes in E-cadherin and vimentin expression.
• Evaluated effects on cell proliferation, viability, invasion, migration, and cell cycle phase distribution.

Main Results:

• Snail gene knockdown led to increased E-cadherin and decreased vimentin expression across all tested cell lines.
• Inhibition of Snail significantly reduced glioblastoma cell proliferation, viability, invasion, and migration.
• Observed an increase in cells within the G1 phase of the cell cycle following Snail knockdown.

Conclusions:

• Snail gene knockdown effectively suppresses glioblastoma cell proliferation, viability, migration, and invasion.
• Inhibition of Snail promotes EMT induction and affects cell cycle progression.
• The Snail gene facilitates glioblastoma progression, highlighting its potential as a therapeutic target.
