ABSTRACT
Acute leukemia is the most common malignant tumor in children in our country.Its pathogenesis includes transformation of proto oncogene,tumor suppressor gene distortion,inhibition of apoptosis etc..Under the action of carcinogenic factors,chromosome mutation,deletion,rearrangement or gene amplification can lead to the structural variation of proto oncogenes and tumor suppressor genes,resulting in a new fusion gene.Some of these genes are tran-scription factors regulating cell proliferation,differentiation,aging and death,when the gene is mutated,directly affect the downstream signaling pathways,leading to cell proliferation,apoptosis and enhanced (or)differentiation disorders, leading to leukemia.In recent years,with the development of gene sequencing technology,more and more leukemia prognostic genes have been displayed in public view and applied in clinical treatment and prognosis,relapse,etc..
