Biological clock genes, which regulate the body’s circadian rhythm, play a crucial role in pancreatic cancer development. The abnormal expression of these genes is closely associated with malignant proliferation, invasion, metastasis, and resistance to chemotherapy. Several biological clock genes in pancreatic cancer tissues contribute to tumor progression by modulating key signaling pathways. Moreover, disruptions in circadian clock genes are significantly linked to poor prognosis and may serve as diagnostic markers and prognostic indicators. This review summarizes recent research on the regulatory mechanisms of biological clock genes in pancreatic cancer, emphasizing their potential clinical applications as diagnostic markers, therapeutic targets, and prognostic tools. These findings may lead to new approaches for personalized pancreatic cancer treatment.
