title: [Detection of Runx2 mRNA expression using relatively real-time RT-PCR in papillary thyroid carcinoma].
abstract: OBJECTIVE
  To relatively detect the Runx2 mRNA expression in papillary thyroid carcinoma (PTC) and thyroid adenoma, then to investigate the role of Runx2 in the development and progression in PTC and the relationship with the micro calcification in PTC.
  
  
  METHODS
  The expression of Runx2 mRNA in 14 samples of PTC and 14 samples of thyroid adenoma was examined by relatively real-time RT-PCR.
  
  
  RESULTS
  The deltaCT value of the carcinoma group and adenoma group was 2.395 +/- 0.302 and 5.028 +/- 1.179 respectively (P<0.01). The 2(-deltadeltaCT) value of the carcinoma group and adenoma group was 7.826 +/- 5.004 and 1 respectively (P<0.01). The carcinoma group was divided into two groups by calcification and there was no statistical difference (P>0.05), and the adenoma group as well. The carcinoma group was divided into two groups by the size of carcinoma (<1 cm and > or = 1 cm). The deltaCT value was 2.629 +/- 0.300 and 2.212 +/- 0.124 respectively (P<0.05) and the 2(-deltadeltaCT) value was 167.33 +/- 33. 823 and 221.69 +/- 18.843 respectively (P<0.01). The TSH level in carcinoma group and adenoma group had no statistical significance (P>0.05).
  
  
  CONCLUSIONS
  The expression of Runx2 mRNA was high in PTC, and was related to the size of carcinoma which was higher in bigger size carcinoma. The role of Runx2 may contribute to the formation of the micro-calcification and the development and progression in PTC and other malignant tumors, such as breast cancer, prostatic carcinoma and osteosarcoma.
