Circadian clock in thyroid cancer: Effects and mechanisms

Area of Science:

• Endocrinology
• Chronobiology
• Oncology

Background:

• The circadian clock regulates essential physiological processes, including thyroid function.
• Disruptions in circadian rhythms, due to factors like shift work or artificial light, are linked to increased thyroid cancer risk.

Purpose of the Study:

• To review the dual role of circadian rhythms in thyroid homeostasis and cancer.
• To elucidate the mechanisms by which circadian clock dysregulation contributes to thyroid carcinogenesis.
• To explore chronotherapy as a potential precision oncology strategy for thyroid cancer.

Main Methods:

• Literature review focusing on circadian rhythms, thyroid function, and carcinogenesis.
• Analysis of molecular pathways linking clock genes (e.g., BMAL1, CLOCK, PER, CRY) to thyroid cancer.
• Examination of chronotherapy principles in the context of thyroid cancer treatment.

Main Results:

• Circadian clock disruption influences thyroid homeostasis and promotes cancer initiation and progression.
• Clock dysregulation is mechanistically linked to oncogenic signaling, immune evasion, and metabolic reprogramming in thyroid cancer.
• Chronotherapy presents a novel approach for precision oncology in thyroid cancer.

Conclusions:

• Circadian rhythms play a critical role in thyroid health and disease.
• Understanding the molecular links between circadian disruption and thyroid cancer can inform new therapeutic strategies.
• Chronotherapy offers a promising avenue for personalized thyroid cancer treatment.
