RNA expression of investigated target genes in strain Neff, strain Neff after plate culture (NeffPl), and three clinical Acanthamoeba isolates (2HH, WIR17, JEA19) after challenge with H2O2 and diamide for two hours. (a) High-molecular weight thioredoxin reductase (TrxR-L), (b) low-molecular weight thioredoxin reductase (TrxR-S), (c) thioredoxin 1 (Trx-1), (d) peroxiredoxin 2 (Prx-2), (e) glutaredoxin 1 (Grx-1), (f) glutathione reductase (GR), (g) glutathione peroxidase (Gpx). Black bars: untreated control; grey bars: treated with 750 μM H2O2; white bars: treated with 2 mM diamide. The y-axis indicates – fold increase of mRNA levels as compared to untreated controls. Error bars show the standard deviation of the mean (SEM). Values were obtained from at least two biological replicates in triplicate. *p < 0.05, **p < 0.01, and ***p < 0.0001 according to statistical analysis (non-parametric Mann–Whitney U test).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
