Study on the Changes of Prohibitin and its Functions During the Apoptosis of the Immortalized Human Epidermal HaCaT cells

Abstract

本论文以姜黄素诱导HaCaT细胞凋亡为基础,运用亚细胞蛋白质组学技术对其凋亡前后核基质组成变化进行系统分析,发现了在细胞凋亡过程中的特异核基质蛋白Prohibitin(PHB),并以此为目标蛋白,研究其在HaCaT细胞中表达与定位及其与相关癌基因、抑癌基因产物的共定位及相互作用关系进行了研究。探索它们在HaCaT细胞凋亡过程中的调控作用,以期能够揭示PHB在人永生化表皮HaCaT凋亡过程中的分子调控网络,从而找出深入探索表皮细胞凋亡的研究方向。 实验结果显示,经7.5μg/mL姜黄素处理之后,人永生化表皮HaCaT细胞的增殖受到明显抑制,细胞体积缩小、细胞核固缩、核内染色质凝聚;琼脂糖凝胶电...This study based on the fact that curcumin can induce the immortalized human epithelial cell line HaCaT cells into apoptosis.In order to explore the molecular mechanisms of apoptosis in a system level ,we use of subcellular proteomics to study the differential expresse of nuclear matrix proteinsand find the special nuclear matrix protein Prohibitin(PHB) during the apoptosis of HaCaT cells, then an...学位:理学硕士院系专业:生命科学学院生物医学科学系_细胞生物学学号:2172008115258
