In this study, we have selected and comprehensively evaluated the expression of four commonly known EMT markers (E-cad, N-cad, VIM, TGFβ1), and four unconventional EMT markers (α-SMA, AKR1B1, ITAV, G6PD), less studied in cancer in relation to the EMT process. The gene discussed is AKR1B1; the disease is cancer.
