摘 要:目的观察p53上调凋亡调控因子(PUMA)在甲状腺乳头状癌(PTC)及其配对癌旁组织(NCE)中的表达,探讨PUMA在PTC发生发展中及其诱导细胞凋亡的作用。方法采用免疫组织化学sP法检测60例PTC及NCE组织PUMA蛋白的表达;应用原位末端标记法(TUNEL)检测vrc及NCE细胞中的凋亡。结果PUMA蛋白在PTC和NCE组织中的阳性表达率分别为40.00%(24/60)、63.33%(38/60)(X。=6.541,P〈0.05)。PUMA在PTC中的表达与患者的TNM分期、淋巴转移及病理分级有关(P〈0.05),与患者的年龄、性别无明显相关(P〉0.05)。PUMA在PTC中的表达与其细胞的凋亡有明显相关(,=12.113,P〈0.01)。结论PUMA作为一种促进凋亡的抑癌基因,参与了PTC的凋亡及发生发展,与PTC的浸润和淋巴结转移有关。Objective To observe the expression of p53 upregulated modulator of apoptosisl (PU- MA) in papillary thyroid carcinoma (PTC) and its roles in inducing apoptosis and the progression of PTC. Methods Immunohistochemical SP technique was used to detect the expression of PUMA protein in 60 ca- ses of PTC and their matched adjacent non-carcerous epithelium (NCE). The apoptosis was assayed by u- sing TdT-mediated dUTP nick end labeling (TUNEL). Results The positive rate of PUMA protein in PTC and NCE was 40% (24/60), 63.33% (38/60) respectively, and the expression of PUMA protein in PTC was significantly lower than that in NCE (X^2 =6. 541 ,P 〈0. 05). PUMA protein was related with the inva- sion and metastasis of PTC ( P 〈 0. 05). There was distinct correlation between the expression of PUMA and apoptosis in PTC (X^2= 12. 113 ,P 〈0.01 ). Conclusion PUMA took part in carcinogenesis and pro- gression of PTC, and it was related with the invasion and metastasis of PTC.
