The role of epigenetic methylations in thyroid Cancer

Area of Science:

• Endocrinology
• Oncology
• Molecular Biology
• Epigenetics

Background:

• Thyroid cancer (TC) incidence is increasing globally, representing a significant endocrine malignancy.
• Epigenetic modifications, which alter gene expression without changing DNA sequence, are increasingly recognized in cancer pathogenesis.
• Specific epigenetic mechanisms, including DNA methylation, RNA methylation, and histone methylation, are implicated in TC development.

Purpose of the Study:

• To provide a comprehensive review of epigenetic modifications in thyroid cancer.
• To elucidate the molecular mechanisms and functional roles of DNA, RNA, and histone methylation in TC.
• To explore the clinical implications and future research directions for epigenetic modifications in TC.

Main Methods:

• Literature review synthesizing current research on epigenetic alterations in thyroid cancer.
• Analysis of molecular mechanisms underlying DNA, RNA, and histone methylation in TC pathogenesis.
• Discussion of clinical relevance, challenges, and future prospects in the field.

Main Results:

• Epigenetic modifications, particularly DNA, RNA, and histone methylation, play a crucial role in the development and progression of thyroid cancer.
• These modifications are reversible and influenced by environmental factors, offering potential therapeutic targets.
• The review highlights specific examples of how these epigenetic changes impact gene expression critical for TC.

Conclusions:

• Epigenetic modifications are integral to thyroid cancer pathogenesis and represent promising biomarkers and therapeutic targets.
• Further research is needed to overcome challenges in studying these modifications and to translate findings into clinical practice.
• Understanding the interplay between epigenetics and environmental factors in TC is crucial for future advancements.
