The TB-N mice also had markedly lower protein levels of matrix metalloproteinases (MMP-2 and MMP-9), mesenchymal markers (vimentin and N-cadherin), and EMT-activated transcription factors (SLUG and SNAIL), as well as a higher expression of E-cadherin protein than did those without Se/FO (Figure 5b,c). This evidence concerns the gene SNAI2 and tuberculosis.
