摘要: 目的 分析TRa1基因转录后小片段P28、P43在甲状腺乳头状癌(Papillary thyroid carcinoma,PTC)组织中的表达水平及其与临床病理的关系。方法 采用实时荧光定量PCR法(RT-PCR)和凝胶电泳法分别扩增目的片段和分离不同片段的条带,再利用紫外透射分析仪扫描各条带的光密度来检测31例PTC组织及癌旁组织中Mt-P28、Mt-P43的表达情况。结果 甲状腺癌组Mt-P28平均灰度值(0.77±0.34)明显高于癌旁组(0.31±0.18);Mt-P43平均灰度值(0.85±0.21)明显高于癌旁组(0.34±0.15),差异均具有统计学意义(P<0.05);Mt-P28表达水平与患者性别、年龄、肿瘤大小、淋巴结转移及临床分期无关(P>0.05);Mt-P43表达水平与患者性别、年龄、肿瘤大小、淋巴结转移无关(P>0.05)而与临床分期有关(P<0.05)。Mt-P28与Mt-P43两者表达水平不具有相关性(r=0.266,P=0.071)。结论 Mt-P28、Mt-P43表达水平的升高倾向于病变恶性程度更高,对预测PTC不良预后有一定的临床应用价值,两种因子对于PTC的预防和治疗有指导意义。

Abstract: Objective The objective of this study was to investigate the expression of P28 and P43 in papillary thyroid carcinoma(PTC)and its relationship with clinicopathological features after TRa1 gene transcription.Methods Real-time fluorescence quantitative PCR(RT-PCR)and gel electrophoresis were used to determine the target fragments and to isolate the bands of different fragments.The optical density of each band was scanned by UV transmittance analyzer to detect 31 cases of PTC tissue and expression levels of P28 and P43 in para-cancerous tissues.Results The average gray value of P28 in thyroid carcinoma group was 0.77±0.34,which was significantly higher than that in para-cancer group(0.31±0.18).The average gray value of P43(0.85+0.21)in thyroid carcinoma group was significantly higher than that in para-cancer group(0.34±0.15)(P<0.05).The expression levels of P28 were not correlated with gender,age,tumor size,lymph node metastasis and clinical pathologic stage(P>0.05),The expression levels of P43 were not correlated with gender,age,tumor size and lymph node metastasis.(P>0.05)but they were related to clinical pathologic stage(P<0.05).There was no correlation between expression levels of P28 and P43(r=0.266,P=0.071).Conclusion The increased expression of P28 and P43 may have a high degree of malignancy and a certain clinical value in predicting the adverse prognosis of PTC.Both factors are helpful for the prevention and treatment of PTC.
