摘要: 目的 分析含CCHC结构域的锌指蛋白12(ZCCHC12)在甲状腺癌组织与甲状腺癌细胞系中的表达,并探讨其对甲状腺细胞恶性转化的影响与机制。方法 采用RT-PCR与Western blot检测30例甲状腺癌患者肿瘤组织和10例良性甲状腺组织以及甲状腺癌细胞系中ZCCHC12的表达。以ZCCHC12腺病毒载体或siRNA转染法处理甲状腺癌细胞,检测细胞增殖、侵袭能力以及相应分子的表达变化情况。结果 与良性甲状腺组织相比,甲状腺癌肿瘤组织中ZCCHC12的mRNA和蛋白表达水平均升高(P<0.05);同时与甲状腺滤泡上皮细胞HUM-CELL-0097相比,甲状腺癌细胞中ZCCHC12的MRNA和蛋白表达也明显升高(P<0.05)。ZCCHC12过表达后甲状腺癌细胞增殖与侵袭能力显著上升(P<0.05),相反,ZCCHC12沉默后其增殖和侵袭能力受到抑制(P<0.05)。与对照组相比,ZCCHC12过表达后细胞周期蛋白D(cyclin D)及基质金属蛋白酶2(MMP-2)、基质金属蛋白酶9(MMP-9)的表达水平增加;ZCCHC12沉默后则降低(P<0.05)。结论 ZCCHC12在甲状腺癌组织及细胞中表达升高,其过表达后甲状腺癌细胞增殖活力与侵袭能力上升。ZCCHC12异常表达可激活细胞周期相关蛋白及胞外基质相关酶的表达,加剧甲状腺细胞的恶性转化。

Abstract: Objective The aims of this study were to analyze the expression of zinc finger protein 12(ZCCHC12)containing CCHC domain in thyroid cancer tissues and cells,and to explore its effect and mechanism on malignant transformation of thyroid cells.Methods The expression of ZCCHC12 in tumor tissues from 30 thyroid cancer patients,10 benign thyroid tissues and cancer cell lines were detected by qRT-PCR and Western blot.ZCCHC12 adenovirus vector or siRNA was used to transfect thyroid cancer cells,and the cell proliferation,invasion ability and expression of corresponding molecules were detected.Results Compared with benign thyroid tissues,the expression of ZCCHC12 in thyroid cancer tissues increased(P<0.05).At the same time,compared with thyroid follicular epithelial HUM-CELL-0097 cells,the expression of ZCCHC12 at levels of mRNA and protein in thyroid cancer cells also significantly increased(P<0.05).After ZCCHC12 overexpression,the proliferation and invasive ability of thyroid cancer cells increased significantly(P<0.05).On the contrary,the proliferation and invasion ability of ZCCHC12 was inhibited after ZCCHC12 silencing(P<0.05).Compared with the control group,the expression of cyclin D,matrix metalloproteinase 2(MMP-2)and MMP-9 increased after ZCCHC12 overexpression and their expression decreased after ZCCHC12 silencing(P<0.05).Conclusion ZCCHC12 is highly expressed in thyroid cancer tissues and thyroid cancer cells,and its proliferative activity and invasion ability increase after overexpression ZCCHC12.The abnormal expression of ZCCHC12 can activate the expression of cell cycle related proteins and extracellular matrix related enzymes,and aggravate the malignant transformation of thyroid cells.
