ZEB1 expression was further evaluated by immunoblotting in two ovarian cancer (OV) cell lines (SKOV3 and ES2), two gastric cancer (GC) lines (SGC7901 and BGC823), two colorectal cancer (CRC) lines (SW620 and HCT15), and two gastrointestinal stromal tumor (GIST) cell lines (GIST882 and GIST430). Here, ZEB1 is linked to ovarian cancer.
