In this paper, we summarize recent studies on the expression and regulation of SHP-1 protein and its pathological function in the development of lymphoma, leukemia and other cancers.
The extraordinarily high frequency (75 to 100%) of CpG methylation of the SHP1 gene in B-cell lymphoma/leukemia patient specimens indicates that the SHP1 gene silencing is one of the critical events to the onset of malignant lymphomas/leukemias as well as important implications for the diagnostic or prognostic markers and the target of gene therapy.
