Low molecular weight tyrosine phosphatase (LMW-PTP) is not found in most EVs in humans; however, it is found among the top 100+ EV markers identified in colorectal cancer [6], exosomes in urine [7], ovarian cancer exosomes (OVCAR-3 line) [8], pro-coagulant microvesicles (fighting against Streptococcus pyogenes) released by peripheral blood mononuclear cells [9], and thymus exosomes [10], among others. This evidence concerns the gene ACP1 and ovarian cancer.
