Linking epithelial-to-mesenchymal-transition and epigenetic modifications

Area of Science:

• Oncology
• Molecular Biology
• Epigenetics

Background:

• Cancer is traditionally linked to genetic mutations in regulatory genes controlling cell growth and DNA repair.
• Tumor development involves mutations in oncogenes and tumor-suppressor genes.
• Emerging evidence highlights the role of epigenetic alterations in cancer.

Purpose of the Study:

• To review recent studies on epigenetic mechanisms in cancer.
• To explore the link between epigenetic alterations and epithelial-to-mesenchymal transition.
• To understand the contribution of epigenetics to oncogenesis.

Main Methods:

• Literature review of recent studies.
• Analysis of epigenetic mechanisms including DNA methylation, histone modifications, and microRNA expression.
• Examination of the role of epigenetics in epithelial-to-mesenchymal transition.

Main Results:

• Aberrant epigenetic changes significantly contribute to malignant transitions in cancer.
• Epigenetic mechanisms are implicated in the epithelial-to-mesenchymal transition process.
• These alterations define the epigenetic landscape of tumor cells.

Conclusions:

• Epigenetic modifications are critical drivers of cancer development and progression.
• Understanding epigenetic mechanisms offers new insights into oncogenesis.
• Targeting epigenetic pathways may hold therapeutic potential for cancer treatment.
