Study on the abnormal expression of the transcription factor FoxO3a and its mechanism in chronic myelocytic leukemia

Abstract

背景:慢性粒细胞白血病(ChronicMyelocyticLeukemia,CML)是一种致命性的恶性造血干细胞疾病,发生源于人9号和22号染色体的易位,导致费城染色体t(9;22)(q34;q11)和融合蛋白P210BCR/ABL的形成。P210BCR/ABL显示异常增强的酪氨酸激酶活性,过度激活下游Ras、PI3K/Akt等信号通路导致肿瘤的发生。FoxO蛋白家族作为转录因子通过调节细胞内多种重要基因的表达,而介导细胞周期、DNA损伤修复、凋亡、氧化应激、细胞分化代谢等细胞生理过程,与肿瘤的发生关系密切。hSHIP(HumanSH2-containinginositol-5-phospha...Background:Chronic myelocytic leukemia (CML) is a lethal hematopoietic stem cell malignancy characterized by the t(9,22) chromosomal translocation,a translocation between the long arms of chromosomes 9 and 22, resulting in the formation of the Philadelphia (ph) chromosome and BCR/ABL fusion protein. BCR/ABL exhibiting constitutively active tyrosine kinase activity interacts with a number of signal...学位:医学硕士院系专业:医学院临床医学系_内科学学号:2452008115342
