VIM and breast cancer: One of the top enriched genes in our GSEA was the mesenchymal marker Vimentin. We assessed the average Vimentin expression in control MGs versus HFD fed MGs using the Luitjen et al.[25] microarray dataset and found that HFD exposed MGs expressed significantly higher levels of the basal-like BC marker Vimentin. The average expression of Vimentin was strikingly tenfold higher with n-3 HFD and 20 fold higher with n-6 HFD (Figure 4C).
