Promyelocytic leukemia-retinoic acid receptor α fusion gene: Research advances / 国际药学研究杂志

Acute promyelocytic leukemia (APL) is a distinctive subtype of acute myeloid leukemia with a distinct biology and clinical presentation. Its molecular biology characteristic is a aberrant chromosomal translocation of the promyelocytic leukemia (PML) gene on chromosome 15 and the retinoic acid receptor α(RARα) gene on chromosome 17. This translocation generates PML-RARα fusion protein, which plays an important role in the genesis, development, diagnosis and therapy of APL. The PML protein has a close relationship with PML-RARα fusion gene. This article mainly summarizes the character, the function of PML protein and the degradation pathway of PML-RARα.
