Fig 4. Thioredoxin reductase activity in auranofin treated Brugia spp.

Fig 4

(A) Activity of endogenous Brugia thioredoxin reductase from soluble worm lysates following incubation with 1% DMSO or 0.3 μM, 0.1 μM, or 0.03 μM of auranofin in vitro. Percentages indicate the percent activity of TrxR compared to DMSO controls. (B) Enzymatic activity of worms collected 16 days after the last dose from gerbils treated with auranofin or vehicle. The lysate of worms taken from gerbils treated with auranofin shows 49% less thioredoxin reductase activity than those taken from gerbils treated with vehicle only. Percentages indicate the percent activity of TrxR compared to vehicle controls.
