Hyaluronidase reduces human breast cancer xenografts in SCID mice.

A hyaluronan-rich environment often correlate with tumor progression. and may be one mechanism for the invasive behavior of malignancies. Eradication of hyaluronan by hyaluronidase administration could reduce tumor aggressiveness and would provide, therefore, a new anti-cancer strategy.

Mystixin peptides reduce hyaluronan deposition and edema formation.

Hyaluronan and its associated water of hydration are the basis of the swelling and edema of acute inflammation. Mystixins are small, synthetic peptides that suppress the acute inflammatory response. Mystixin-7, a prototype of these peptides, has the structure p-anisoyl-Arg-Lys-Leu-Leu-D-Thi-Ile-D-Leu-NH(2).

Lactate stimulates fibroblast expression of hyaluronan and CD44: the Warburg effect revisited.

Hyaluronan, a high-molecular-weight glycosaminoglycan of the extracellular matrix, is prominent during rapid tissue growth and repair. It stimulates cell motility and hydrates tissue, providing an environment that facilitates cell movement. Markedly enhanced levels of hyaluronan also occur in the stroma surrounding human cancers, thus providing an environment that promotes spread of cancer cells.
