Abstract:
The P53 gene has the important functions including induction of apoptosis, regulation of cell cycle, repair of DNA damage. The mutation of the P53 gene exists in more than 50% of human tumors and 13% of hematological malignancies. The P53 gene abnormality is closely related with the clinical course and prognosis of leukemia. The P73 or P63 gene, the member of the P53 family not only possesses similar to P53 activity of inducing apoptosis, activating transcription, but also plays different biological effects according to protein structural diversity, and even antagonises the function of the P53 gene. Researchers found that P73 or P63 gene also has the dual characteristics of the tumor suppressor and oncogene, and shows different expression and function in different types, different stages of leukemia. In this article, P53 family (P53, P73, P63) gene structure, biological function and the relationship of the three genes with the course, prognostic outcome, treatment and other clinical features of the leukemia are reviewed.
