ING5 inhibits epithelial-mesenchymal transition in breast cancer by suppressing PI3K/Akt pathway

Area of Science:

• Oncology
• Molecular Biology
• Cancer Research

Background:

• Epithelial-mesenchymal transition (EMT) drives cancer invasion and metastasis.
• The Inhibitor of Growth (ING) gene family, including ING5, has roles in cell cycle regulation and apoptosis.
• The specific function of ING5 in breast cancer progression remains largely uncharacterized.

Purpose of the Study:

• To investigate the role of ING5 in the pathogenesis of breast cancer.
• To determine the effect of ING5 on cancer cell migration, invasion, and EMT.
• To elucidate the molecular mechanisms underlying ING5's function in breast cancer.

Main Methods:

• Analysis of ING5 expression in breast cancer tissues and cell lines.
• Overexpression of ING5 in breast cancer cells.
• Assessment of cell migration, invasion, and EMT markers.
• Evaluation of PI3K/Akt signaling pathway activation.

Main Results:

• ING5 expression was found to be significantly down-regulated in breast cancer tissues and cell lines.
• Overexpression of ING5 markedly inhibited breast cancer cell migration, invasion, and EMT.
• ING5 overexpression led to decreased phosphorylation of PI3K and Akt.

Conclusions:

• ING5 plays a suppressive role in breast cancer progression.
• ING5 inhibits EMT in breast cancer cells by down-regulating the PI3K/Akt signaling pathway.
• ING5 represents a potential molecular target for breast cancer prevention and therapy.
