Objective: To investigate the expressions and their relationship of pituitary tumor transforming gene (PTTG) and proliferating cell nuclear antigen (PCNA) in glioma. Methods: The protein expressions of PTTG and PCNA were detected by immunostaining assay using streptavidin-peroxidase (SP) method in 80 cases of glioma. Results: The positive rates of PTTG in grades Ⅰ-Ⅳ gliomas were 56.3%, 68.2%, 80.8%, and 100.0% respectively, and the protein expression of PTTG increased with the increasing of the pathological grade (X^2= 9.602, P 〈 0.05); The positive rates of PCNA protein were 37.5%, 54.5%, 69.2%, and 93.8% respectively, and the protein expression of PCNA increased with the increasing of the pathological grade (X2 = 12.147, P 〈 0.01). The expression of PTTG had positive correlation with the expression of PCNA protein (~s = 0.557, P 〈 0.01). Conclusion: The expressions of PTTG and PCNA proteins were related to malignant degree of glioma, and may cooperate with each other in the tumorigenesis and progression and can be considered as the indicators of the biological behaviors in glioma. 相似文献

Objective: The aim of the study was to investigate the relationship between expressions of estrogen receptor (ER), progesterone receptor (PR) and gender, age, tumor size, lymph node metastasis, capsular invasion and histological type of differentiated thyroid carcinoma (DTC). Methods: Seventy cases of DTC who received surgery in our hospital (No. 401 Hospital of People's Liberation Army, Qingdao, China) between January 2008 and December 2011 were selected. Among them, 61 cases were papillary carcinoma and 9 cases were follicular carcinoma. Twenty cases were normal thyroid tissue adjacent to the tumor which was used as control. Immunohistochemical SP method was employed to detect the expression of ER and PR. Results: The positive rates of ER and PR in tumor tissues of DTC patients were 21.4% (15/70) and 31.4% (22/70), respectively, and no expression of ER or PR were founded in normal thyroid tissue (P 〈 0.01). The expressions of ER and PR were related to the lymph node metastasis and capsular invasion (X2 = 16.913 and 6.327, P 〈 0.05; x2 = 7.516 and 12.727, P 〈 0.05). No relationship was observed between the expressions of EPJPR and gender, age, and histological type (P 〉 0.05) of DTC patients. Conclusion: The expression levels of ER and PR in the tumor tissue of DTC patients were higher than those in the normal thyroid tissue nearby the tumor. Therefore, ER and PR expression might be clinical markers for DTC and its prognosis. 相似文献
