[Research advance of p53 gene in mantle cell lymphoma]

Mantle cell lymphoma(MCL) is an independent uncommon subtype of B-cell non-Hodgkin's lymphoma (NHL) according to World Health Organization classification of hematopoietic and lymphoid tissue tumors. The genetic hallmark of MCL is the chromosomal translocation t(11;14)(q13;q32) that leads to upregulation of cyclin D1, an important regulator of the G(1) phase in the cell cycle. This genetic aberration is virtually present in all cases of MCL. It is characterized by distinct clinical features and outcome which is affected by a series of additional genetic aberration including the genomic guardian-P53 gene. This article reviews the effects of P53 gene aberrations including P53 deletion, mutation and their mutual relationship in MCL, and novel therapeutic regimens for MCL patients with P53 aberrations.
