Extracellular thioredoxin and thioredoxin-binding protein 2 in control of cancer.

Abstract

Thioredoxin-1 (TRX) is a redox-active protein with multiple intracellular and extracellular functions. Intracellular redox balance is maintained by the TRX family and its related molecules. Extracellular TRX shows cytoprotective effects, while truncated Trx80 has more mitogenic activity. Exogenously administered TRX does not promote the growth of cancer in vivo and shows anti-chemotactic effect for neutrophils and anti-inflammatory functions. Thioredoxin is released from cells in response to oxidative stress and TRX levels in plasma or serum are good markers for oxidative stress associated with cancer. Thioredoxin-binding protein 2 (TBP-2) is an endogenous negative regulator of TRX and a tumor suppressor.
