融合蛋白AML1-ETO的生物学功能及致癌机制探讨
Biological function and cancerogenic mechanism of AML1-ETO fusion protein
摘要
Abstract
AML1 - ETO fusion protein is the product of ( 8; 21 ) translocation in M2 type acute myelocytic leukemia ( AML ). As a transcription repressor, AML1 - ETO can block the differentiation of hematopoietic cells by repressing the expression of some important hematopoiesis -related transcription factors. Recent results indicate that the fusion protein also induces the epigenetic silencing of some target genes, resulting in the delay of hematopoietic maturation.Moreover, AML1 -ETO promotes the proliferation of hematopoietic stem cells through up -regulating the expression of Jagged1 and miR - 24. Meanwhile, a panel of results in the pathogenesis of AML1 - ETO show that the expression of AML1 -ETO alone can not induce AML. The secondary events or hits like c - kit gene mutation and the AML1 - ETO9a truncation play an important role in leukemogenesis of AML1 - ETO - positive cells.关键词
