  • Expression and Clinical Significance of Tumor Suppressor Gene TIP30 in Papillary Thyroid Carcinoma

    ObjectiveTo investigate the expression of tumor suppressor gene Tat interacting protein 30 (TIP30) gene in papillary thyroid carcinoma and it’s clinical significance in treatment of thyroid carcinoma. Methods Thirty cases of pathological specimens wax pieces of papillary thyroid carcinoma from 2003 to 2006 in our hospital were selected, in which there were 7 male, 23 female; and the age was from 15 to 70 years old, average 44.7 years. Six cases were nodular goiter with carcinomatous change in local area (papillary), 2 cases were thyroid capsular invasion. Distant lymph node metastasis and lesions surrounding the thyroid tissue were not confirmed by pathology. Every specimen was divided into tumor tissue and adjacent tissue (1-2 cm far away from tumor and non-cancerous tissue was confirmed by pathology). The expression of TIP30 in specimen was detected by immunohistochemical method with staining index and the average absorbance. ResultsTIP30 was expressed in the cell membrane and cytoplasm, which was showed as brown particles. ①Staining index: TIP30 in adjacent tissues was expressed highly with 21 (70.0%) positive cases (gt;2 points) and 9 (30.0%) negative cases (≤2 points), while its expression in cancer tissues was reduced or missed with 11 (36.7%) positive cases (gt;2 points) and 19 (63.3%) negative cases (≤2 points). There was a statistical difference between them (P<0.05), and it was not related to age and gender of patients (Pgt;0.05). ②The average absorbance of TIP30 in cancer tissues was significantly lower than that in adjacent tissue (P<0.05). ConclusionThe expression of TIP30 in papillary thyroid carcinoma is reduced or deleted, which can supply some theory support for its gene therapy.
