CONTEXT: Dysregulation of circadian rhythms has been linked to cancer susceptibility. Thyroid cancer cells demonstrate altered circadian oscillations in endogenous clock transcripts.
OBJECTIVE: Our previous research identified NR1D1, a component of the circadian clock, as one of the recurrence-associated genes in papillary thyroid cancer. The objective of this study was to investigate the expression pattern of NR1D1 in thyroid cancer and explore its prognostic and translational implications.
METHODS: We assessed NR1D1 expression using immunohistochemical analysis and examined its correlation with clinicopathological parameters. In vitro and in vivo experiments were performed to elucidate the oncogenic roles of NR1D1 and potential mechanisms.
RESULTS: Nuclear NR1D1 expression was present in thyroid follicular epithelial-derived cancers, whereas normal thyroid tissue and benign nodular goiter showed no detectable NR1D1 immunoreactivity. Patients with high expression of NR1D1 had more advanced disease stages, extrathyroidal extension, lymphovascular invasion, and shorter recurrence-free survival compared to those with low levels of NR1D1. Through gain- and loss-of-function studies, we demonstrated that NR1D1 modulation affected the growth of organoids, resistance to anoikis, and the invasive and migratory capacity of thyroid cancer cells. The invasion-promoting effect of NR1D1 was regulated by the β-catenin/ZEB1 axis. Moreover, the overexpression of NR1D1 accelerated xenograft growth and lung metastasis in vivo.
CONCLUSION: NR1D1 is overexpressed in malignant thyroid tumors and has prognostic significance. Our findings suggest therapeutic potential in targeting NR1D1 for thyroid cancer.
