Abstract:
Objective To investigate the protein expression of stanniocalcin 1 (STC1) in papillary thyroid carcinoma (PTC) in gerontal patients versus non-gerontal subjects,and its relationship with clinicopathological features.Methods The protein expression levels of STC1 in PTC,nodular goiter and normal thyroid tissues in the gerontal patients versus non-gerontal subjects were detected by immunohistochemistry.The protein expressions of STC1 were detected by Western blotting.Results The protein expression of STC1 in gerontal patients was higher in PTC than in nodular goiter and normal thyroid tissues (60.9％ vs.30.0％,15.0％,P＜0.05 or 0.01).The relative expression of STC1 protein in gerontal patients was higher in PTC than in nodular goiter and normal thyroid tissues [(0.647 ± 0.076) vs.(0.280 ± 0.039),(0.248 ± 0.065),F =9.965 and 1.143,both P＜0.01].STC1 protein expression had no correlations with age,gender,tumor diameter and tumor position in patients (P＜0.05),while it was associated with tumor lymph node metastasis and clinical stage (P＜0.05).There was no significant difference in above indexes between the elderly and non-elderly patients with papillary thyroid carcinoma (F=0.007,P=0.934).Conclusions STC1 protein may be associated with the development of papillary thyroid carcinoma,and it may has a some reference value in differentiating benign from malignant thyroid neoplasms and in predicting the prognosis of thyroid carcinomas.
