摘要:
 目的 研究核糖体S6蛋白磷酸化(ribosomalS6proteinphosphorylation,P-S6)和细胞周期蛋白D1(CyclinD1)在翼状胬肉中的表达及相关性,探讨哺乳动物雷帕霉素靶蛋白复合物1(mammaliantargetofrapamycincomplex1,mTORC1)信号通路在翼状胬肉发病机制中的作用。方法 收集翼状胬肉组织31例,正常结膜组织17例,利用免疫组织化学和Westernblot进行P-S6和CyclinD1的检测及比较。结果 Westernblot检测6例翼状胬肉组织中P-S6蛋白/S6蛋白表达(1.196±0.101)显著高于正常结膜组织(0.295±0.056),差异有统计学意义(P<0.05)。免疫组织化学染色结果显示:翼状胬肉中P-S6、CyclinD1的阳性表达率均为100%(25/25),正常结膜组织中P-S6阳性表达率为18.2%(2/11)、CyclinD1阳性表达率为9.1%(1/11),正常结膜组织与翼状胬肉组织中P-S6与CyclinD1表达差异均有统计学意义(均为P<0.05)。翼状胬肉组织中P-S6与CyclinD1的表达呈正相关(r=0.752,P<0.05)。结论 mTORC1信号通路在翼状胬肉发病过程中起重要作用,并可能通过调控CyclinD1的表达来实现。
Abstract:
 Objective To investigate the expression and relationship between ribosomal S6 protein phosphorylation ( P-S6) and CyclinDI in the pterygium , and explore the role of mammalian target of rapamycin complex I ( mTORCI ) signaling pathway in the pathogenesis of pterygium. Methods Thirty-one pterygium specimens were obtained , and 17 normal conjunctival specimens were also collected. The expression of PS6 and CyclinDI were examined by immunohistochemistry and Western blot. Results Western blot showed that the P-S6 protein/S6 protein in 6 cases of pterygium speci- men (1. 196 + 0. 101 ) was higher than that of normal conjunctiva tissues ( 0. 295 + 0. 056) , the difference was statistical sigruficant (P < 0. 05 ). Immunohistochemistry showed that the positive rate of P-S6 was 100. 0% ( 25/25 ) in pterygium and 18. 2% ( 2/ II) in normal conjunctiva, and the positive rate of CyclinDI was 100. 0% ( 25/25 ) in pterygium and 9. 1% ( 1/11 ) in normal conjunctiva. there were significant differences in the expressions of P-S6 and CyclinDI between pterygium and normal conjunctiva ( all P < 0. 05 ) . There existed positive correlation between the expression of P-S6 and CyclinDI in the pterygium ( r = 0. 752. P < 0. 05 ). Conclrision The activation of mTORCI signaling pathway plays an important role in the pathogenesis of pterygium, which may be achieved by regulating the expression of CyclinDI.
