ZEB1 and lung carcinoma: Furthermore, there were statistically significant differences in OS, PFS, and DMFS between patients with low and high expression of Snail (Fig. 6A), Twist1 (Fig. 6B), and ZEB1 (Fig. 6C), indicating that increased expression of Snail, Twist1, and ZEB1 was correlated with lung cancer progression and poor patient survival.
