The results obtained from the western blot analysis revealed a significant decrease in the level of E-cadherin protein in the lung infected with H37Rv and H37RvΔRv2569c + Rv2569c strains relative to that in the lung infected with H37RvΔRv2569c strain, at 14 and 30 days after infection (Fig 8A and 8B). Here, CDH1 is linked to infection.
