Notably, the heparanase inhibitor PG545 (= pixatimod, a highly sulfated tetra-saccharide bound to a lipophilic cholestanol aglycone) appeared more effective than cisplatin, a common chemotherapeutics in mesothelioma, in restraining tumor growth, closely associating with a profoundly prolonged survival of mesothelioma-bearing mice (Figure 1B). The gene discussed is HPSE; the disease is mesothelioma.
