Fig. 5From: Sex affects the response of Wistar rats to polyvinyl pyrrolidone (PVP)-coated silver nanoparticles in an oral 28 days repeated dose toxicity studyProtein expression of two multimeric forms (~ 42 kDa and ~ 24 kDa) of metallothionein MT1/2 proteins, in the liver and kidneys of male (gray columns) and female (white columns) rats after administration of LD and HD of PVP-AgNPs. a, b Represent Western blot images for liver and kidneys, respectively, while c, d diagrams show protein expression levels in liver and kidneys, respectively, presented as relative values compared to control samples. Error bars: SD. *p < 0.05 and **p < 0.001 between controls (Ctl) and treated animalsBack to article page
