Molecular targets for epigenetic therapy of cancer

Area of Science:

• Oncology
• Epigenetics

Background:

• Epigenetic alterations in the cell epigenome significantly contribute to cancer development and progression.
• Epigenetic modifications, like genetic changes, can be heritable and regulate gene expression, potentially aiding cancer cell survival.
• The reversible nature of epigenetic changes presents an opportunity for epigenetic therapy.

Purpose of the Study:

• To summarize recent studies on epigenetic modifications in cancer.
• To discuss the differences between conventional chemotherapy and epigenetic therapy.
• To explore current perspectives on the future of epigenetic therapy.

Main Methods:

• Review of recent advances in cancer research focusing on epigenetics.
• Analysis of studies identifying differentially expressed genes in cancer cells versus normal cells.
• Discussion of epigenetic drugs, including DNA methyltransferase inhibitors and histone deacetylase inhibitors.

Main Results:

• Epigenetic changes play a significant role in cancer initiation and progression.
• Epigenetic therapy offers a potentially reversible treatment strategy.
• Identifying specific molecular targets is crucial for effective and specific epigenetic therapy.

Conclusions:

• Epigenetic therapy, distinct from conventional chemotherapy, utilizes drugs targeting epigenetic mechanisms.
• Lack of specificity remains a challenge, necessitating identification of cancer-specific epigenetic targets.
• Ongoing research into differentially expressed genes is vital for advancing epigenetic therapy in oncology.
