Abstract:
Objective To investigate the expression of thanatos-associated protein-8 (THAP-8) in ovarian cancer tissue,and explore its clinical significance.Methods A total of 86 patients with ovarian cancer were enrolled.The gene and protein expression of THAP-8 of the ovarian cancer tissue and adjacent tissue were detected by fluorescent quantitation polymerase chain reaction and immunohistochemistry.Results The gene expressions of THAP-8 of ovarian cancer tissue and adjacent tissue were 0.304 ± 0.104 and 0.615 ± 0.152.The protein expressions of THAP-8 in ovarian cancer tissue and adjacent tissue were 30.16 ± 12.34 and 67.34 ± 22.37.The gene and protein expressions of THAP-8 in ovarian cancer tissue were significantly lower than those in adjacent tissue (P＜ 0.01).The gene and protein expressions of THAP-8 in the low and middle degree of tumor differentiation of ovarian cancer tissue were significantly lower than those of the high degree of tumor differentiation of ovarian cancer tissue (0.216 ±0.085 vs.0.457 ±0.124 and 24.22 ± 9.21 vs.46.24 ± 17.52,P ＜ 0.01 or ＜ 0.05).The gene and protein expressions of THAP-8 in lymph node metastasis of ovarian cancer tissue were significantly lower than those of no lymph node metastasis of ovarian cancer tissue (0.247 ± 0.087 vs.0.476 ± 0.133 and 23.44 ± 8.57 vs.49.60 ± 18.35,P ＜ 0.01 or ＜0.05).The gene and protein expressions of THAP-8 in clinical TNM pathologic Ⅲ,Ⅳ stage of ovarian cancer tissue were significantly lower than those of Ⅰ,Ⅱ stage of ovarian cancer tissue (0.232 ± 0.114 vs.0.424 ±0.125 and 25.64 ±8.12 vs.44.78 ± 16.84,P ＜0.05).Conclusions The downregulation-expression of THAP-8 has a closed relationship with the development of ovarian cancer.The THAP-8 might be used as a potential marker to assess the degree of rumor grade and prognosis in ovarian cancer.
