VIM and Alzheimer disease: Western blotting results were consistent with the proteomics data where analyses revealed a statistically significant increase in protein expression of catalase and vimentin (p < 0.05; student’s t-test) and a decrease in expression of caspase 3 and EpCAM (p < 0.05; student’s t-test) in PLum-AI cell samples when compared to PLum-AD cells (Figure 3).
