mRNA and protein level of NDRG2 in lung cancer and normal tissues, and relationship between NDRG2 level and clinical pathological parameters in lung cancer. RT-PCR (a) and western blot (b) shown that the mRNA and protein levels of NDRG2 in six lung cancer tissues (T) and cognate normal tissues (N). Three types of lung cancer (SC, AC, SCLC) exhibited significant difference of NDRG2 mRNA level in comparison with normal tissues, respectively. c NDRG2 mRNA level was positively correlated with tumor differentiation grade in both SC and AC (d) and was negatively correlated with UICC stage (e). *P < 0.05, **P < 0.01
