Copy number of cell-free ND1 DNA in plasma and blood cells. The copy number of ND1 in plasma (A) and blood cells (B), and copy number of ND1 normalized by nDNA (GAPDH) in plasma (C) and blood cells (D) of thyroid cancer and thyroid nodule patients were detected by quantitative fluorescence PCR. Total ND1 copy number was significantly higher in both blood and plasma in patients with thyroid nodule or thyroid tumor. No significant differences were found among the three groups after normalizing for nDNA. The number below the scatter in the figure is the mean value of each experimental group.
