| Outline of Final Research Achievements |
We analyzed to clarify the multistep tumorigenic events in adult T cell leukemia/lymphoma (ATLL) by focusing on SHP1. SHP1 is a nonreceptor type protein-tyrosine phosphatase, which acts as a negative regulator in hematopoietic cells. In immunostaining, the expression of SHP1 and tumor-related genes decreased in various ATLL-related cell lines. By performing methylation specific PCR (MSP) assay, we detected aberrant methylation of SHP1 and these genes. Moreover, we identified specific aberrant DNA methylation profile in ATLL-related cell lines. Our findings demonstrate that the presence of aberrant methylation is deeply involved in the development and progression of ATLL in multistep leukemogenesis.
