What is the role of hyaluronidases in cancer?

The enzyme is hyaluronidase, and it breaks down hyaluronic acid (HA), a large, complex sugar polymer present in human tissues. HA is also present in tumors, and when hyaluronidase produced by tumor cells breaks down HA the small fragments help the cancer to spread in the body.

What is the role of hyaluronidase?

Hyaluronidase, an enzyme that breaks down hyaluronic acid, has long been used to increase the absorption of drugs into tissue and to reduce tissue damage in cases of extravasation of a drug.

What is the role of hyaluronidase in pathogenesis?

Since hyaluronate is a major constituent of the ground substance of most connective tissues, particularly the skin, hyaluronidase may be an essential component in enabling the spread of the pathogens from an initial site of infection.

What is the role of hyaluronidase in fertilization?

Role in fertilization In mammalian fertilization, hyaluronidase is released by the acrosome of the sperm cell after it has reached the oocyte, by digesting hyaluronan in the corona radiata, thus enabling conception. Once this occurs, the sperm is capable of binding with the zona pellucida.

• redness of the skin.
• skin rash.
• unusual tiredness or weakness.

Does hyaluronidase spread?

Since hyaluronidases are enzymes that catalyze the breakdown of hyaluronic acid in the body, they may increase the permeability of tissue to fluids. Hyaluronidase in snake and insect venom is thought to function as a “spreading factor” by degrading host hyaluronic acid, thus allowing spread of toxin (13).

When would you use hyaluronidase?
