ABSTRACT
In recent years,accumulating evidence shows that phosphatase of regenerating liver-3(PRL-3)is closely implicated in tumor progression,especially in the stages of invasion and metastasis of various solid tumors, inclu-ding colorectal cancer,gastric cancer and breast cancer.However,the study of PRL-3 in hematological malignancies is rel-atively lagged,but there are some advances in leukemia and myeloma,in which PRL-3 up-regulation is tightly associated with poor prognosis,while the underlying mechanism of signal transduction is gradually explored.In this review,we sum-marized the recent advances of PRL-3 in hematological malignancies such as acute myeloid leukemia,multiple myeloma and chronic myeloid leukemia,as well as the molecular mechanism of PRL-3 in pathogenesis.
