Thioredoxin acts as a B cell growth factor in channel catfish.

The Human Thioredoxin System: Modifications and Clinical Applications

The thioredoxin system, comprising thioredoxin (Trx), thioredoxin reductase (TrxR) and NADPH, is one of the major cellular antioxidant systems, implicated in a large and growing number of biological functions. Trx acts as an oxidoreductase via a highly conserved dithiol/disulfide motif located in the active site ( Trp-Cys-Gly-Pro- Cys-Lys-). Different factors are involved in the regulation of T...

Cell growth stimulation by the redox protein thioredoxin occurs by a novel helper mechanism.

Thioredoxins are a class of low molecular weight redox proteins that undergo reversible reduction-oxidation of two active-site cysteine residues with reduction catalyzed by the NADPH-dependent flavoenzyme thioredoxin reductase. Human thioredoxin has been shown to be identical to a previously reported leukemic cell growth factor. We now report that recombinant human thioredoxin added to minimal ...

Factors Affecting Regional Variation in Growth of Channel Catfish

—We related the length at age of channel catfish Ictalurus punctatus, an indirect measure of growth, to three climatic and five morphoedaphic variables in 144 Texas reservoirs. Growth of channel catfish ages 3 through 6 was negatively related to longitude, a factor that explained as much as 34% of the variation in length at age. Channel catfish length at age was not significantly related to lat...
