Indeed, while PDAC with high grade-TB demonstrated an increased expression of mesenchymal markers such as vimentin [20,29], ZEB1 and ZEB2 [27], PDAC with low grade-TB showed a reduced or focal expression of epithelial markers, like E-cadherin [27,28,29], cytokeratin [22] and p63 [26]. The gene discussed is VIM; the disease is tuberculosis.
