title: Study on extracellular matrix metalloproteinase inducer and human epidermal growth factor receptor-2 protein expression in papillary thyroid carcinoma using a quantum dot-based immunofluorescence technique.
abstract: The aim of the present study was to investigate the association of extracellular matrix metalloproteinase inducer (EMMPRIN) and human epidermal growth factor receptor (HER)-2 protein expression in papillary thyroid carcinoma with lymph node metastasis (LNM), as well as the correlation between the two types of protein expression. A quantum dot-based immunofluorescence technique was used to detect EMMPRIN and HER-2 protein expression in 75 papillary thyroid carcinoma cases (including 70 cases of papillary thyroid carcinoma tissues and 5 cases of peri-tumor tissues). The positive rate and expression of EMMPRIN and HER-2 were compared and observed. The positive rate of EMMPRIN was 75.71% in papillary thyroid carcinoma tissues and 20.00% in peri-tumor tissues (P<0.05). The positive rate of HER-2 was 45.71% in papillary thyroid carcinoma tissues and 0% in peri-tumor tissues (P>0.05). The expression of EMMPRIN and HER-2 in papillary thyroid carcinoma was significantly associated with LNM (P<0.05). In addition, in the 70 papillary thyroid carcinoma tissues, the expression of EMMPRIN and HER-2 was positively and significantly correlated. In conclusion, this study demonstrates that the co-evolution of EMMPRIN and HER-2 may promote the occurrence and development of papillary thyroid carcinoma and LNM.
