Abstract
Hyaluronan is one of the major components of the extracellular matrix and is involved in the regulation of multiple processes in both human physiology and disease. In human cancers, hyaluronan metabolism displays remarkable alterations, leading to the accumulation of large amounts of hyaluronan matrices in the tumoural tissues. The altered levels of hyaluronan in the tumours stem from the enhanced expression and activity of hyaluronan synthases in both tumour and stromal cells. Moreover, hyaluronidase activity is also upregulated in cancer, leading to the generation of lower molecular weight hyaluronan fragments that in turn assist tumour growth, neo-angiogenesis and the metastatic cascade. Hyaluronan accumulation in malignant tissues not only assists tumour growth and metastases but is also associated with worse outcomes in cancer patients. Therefore, targeting hyaluronan synthesis emerges as an interesting strategy that might be employed for cancer treatment. This review article summarises current evidence and discusses ways to move forward in the field of targeting hyaluronan synthesis for cancer therapy.
