The abundant presence of a protein known as low molecular weight tyrosine phosphatase (LMWPTP) in tumor cells has been identified as an indicator of aggressiveness and metastatic potential. It is known that, under normal conditions, LMWPTP has important functions in cells, participating in both the proliferation process and the regulation of intracellular systems. Its pro-cancer action is still being unraveled...
