Increased expression of 10/16 stemness genes studied (SOX2, OCT3, MYC, TGFBR1, KLF4, TGFB1, LAT, LMNB2, SMAD2, VIM) was also observed in the EpCam+ tumor cells extracted from the tumor of patient St23784/17 compared with the EpCam+ tumor cells from patient Ti41749/17 (Figure 2I). The gene discussed is KLF4; the disease is neoplasm.
