Correlation of IKZF1 Gene with Malignant Tumors and Systemic Lupus Erythematosus / 中国实验血液学杂志

IKZF1 gene located in 7p12 of chromosome, and Ikaros family zinc finger encoded by IKZF1, are lymphoid-restricted transcription factors. In recent years, it has been demonstrated that the mutation of IKZF1 gene involved in proliferation, metastasis and prognosis of many malignant tumor except acute lymphoblastic leukemia, and also involved in complex phenotypes and susceptibility to systemic lupus erythematosus. This review briefly introduces the molecular structure and physiological function of Ikaros, focusing on its function and molecular mechanism in proliferation, metastasis and prognosis of malignant tumors, and its role in the systemic lupus erythematosus.

Recent research progress on the relation of B-ALL associated cytogenetic and molecular genetic abnormalities with B-ALL prognosis / 中国实验血液学杂志

In recent years, standardized treatment based on the risk stratification has been applied to clinical diagnosis and treatment of leukemia, which significantly improves the remission rate of ALL. However, relapse after remission remains an important challenge for long term efficacy. Chromosomal karyotype analysis is often used clinically to study the genetic features of ALL. As leukemia-specific markers, the cytogenetic and molecular genetic abnormalities can be used to evaluate prognosis and make an effective and optimal therapy. Furthermore, they are also used to track minimal residual disease. Therefore, the cytogenetic and molecular genetic abnormalities may become a monitor and a new target for the treatment of leukemia. This review briefly introduces the structure and physiological function of B-ALL associated cytogenetic and molecular genetic abnormalities, focusing on their prognostic effect on B-ALL.
