CLOCK and thyroid gland carcinoma: Expression of this gene was not tested in the remaining four studies of Mond et al. (2014) [2], Makhlouf et al. (2016) [4], Gallo et al. (2018) [5], or Xu et al. (2022) [8], but the results of these studies allowed the extension of the list of circadian clock genes demonstrating abnormal expression in thyroid carcinoma.
