New treatment options for metastasised high-grade serous carcinoma (HGSC) are urgently needed. HGSC frequently metastasises to the omentum, inducing angiogenesis in local omental microvasculature facilitate tumour growth. We previously showed that HGSC-secreted cathepsin L (CathL) induces pro-angiogenic changes disease relevant human microvascular endothelial cells (HOMECs), suggesting a role angiogenesis. Here we investigate whether CathL acts by production of carbohydrate-binding protein...
