PLAUR and neoplasm: Human and mouse uPA1-48 (huPA1-48 and muPA1-48), human and murine uPA1-48 fusion proteins (huPA1-48Ig and muPA1-48Ig) [120], and human and mouse pegylated uPA1-48 (PEGh1-48 and PEGhm1-48) [121] also inhibit tumour growth by inhibiting tumour stromal cell uPAR-dependent plasminogen activation.
