Epigenetic regulation in cancer progression

Area of Science:

• Oncology
• Molecular Biology
• Epigenetics

Background:

• Cancer arises from genetic and epigenetic DNA modifications affecting gene expression.
• Epigenetic changes, including DNA and histone alterations, silence tumor suppressors and activate oncogenes.
• These changes can lead to tumorigenesis by altering cellular control systems.

Purpose of the Study:

• To review the various epigenetic changes in cancer.
• To discuss how epigenetic modifier deregulation drives cancer progression.
• To explore off-target effects of epigenetic modifiers and hypoxia's role.

Main Methods:

• Literature review of epigenetic alterations in cancer.
• Analysis of the role of epigenetic modifiers in tumor progression.
• Discussion of off-target effects and hypoxia in epigenetic regulation.

Main Results:

• Excessive epigenetic modifiers correlate with aggressive breast cancer and metastasis.
• Some poor-prognosis tumors are epigenetically deregulated despite lacking genetic alterations.
• Epigenetic changes play a significant role in tumorigenesis and cancer recurrence.

Conclusions:

• Epigenetic alterations are critical drivers of cancer, influencing progression and metastasis.
• Understanding epigenetic deregulation is key to developing new cancer therapies.
• Further research into epigenetic modifiers and their off-target effects is warranted.
