摘要

PRL-3, a protein tyrosine phosphatase (PTP), has a significant influence on the pathogenesis of various cancers with its overexpression significantly correlating with tumor invasion, metastasis and poor prognosis. It significantly affects tumor cell behavior through its involvement in cell proliferation, migration and metabolic processes. Furthermore, the interaction between PRL-3 and the tumor microenvironment characterized by its adaptability to stress and its role in metabolic reprogramming enhances tumor cell survival and dissemination. Targeted therapies against PRL-3, encompassing small molecule inhibitors and the monoclonal antibody PRL-3-zumab, have shown promise in clinical and preclinical studies, presenting new avenues for cancer treatment. In addition, innovative approaches such as CAAX motif-targeting agents and PRL-3 degradation strategies hold promise for developing more precise and effective interventions. This review explores PRL-3’s multifaceted roles across different tumor types and microenvironments, while discussing current and emerging therapeutic strategies aimed at exploiting its oncogenic potential.
