The PCR results for MMPs and TIMPs. Agarose gel electrophoresis showing that the lengths of the mRNA fragments of MMP-2, MMP-9, TIMP-1, and TIMP-2 were 320 bp, 582 bp, 405 bp, and 372 bp, respectively. The PCR bands of MMPs and TIMPs in patients with DTC were the brightest; after surgery, the brightness of these bands was significantly reduced. Moreover, there were no significant differences compared with the control group and the benign thyroid tumor group. 1: β-actin; 2: healthy individual; 3: benign thyroid tumor (prior to surgery); 4: benign thyroid tumor (after surgery); 5: DTC (prior to surgery); 6: DTC (after surgery).
