Correlation between Dab2 expression and lung cancer clinical characteristics as well as lung cancer patients’ outcome. a High cytoplasmic expression of Dab2 in well-differentiated adenocarcinoma cells (a, IHC, 400×); Negative expression of Dab2 in poorly-differentiated adenocarcinoma cells (b, IHC, 400×); Medium cytoplasmic and strong nuclear expression of Dab2 in well-differentiated squamous cell carcinoma cells (c, IHC, 400×); Negative expression of Dab2 in poorly-differentiated squamous cell carcinoma cells (d, IHC, 400×). b Kaplan-Meier analysis demonstrates that low Dab2 expression is positively correlated with poor outcome of lung cancer patients (P < 0.05)
