Expression of MNK2 was investigated by IHC with MNK2 monoclonal antibodies by using NSCLC tissue microarray that contained 367 NSCLC tissues and 117 normal lung tissues, compared with normal lung epithelial, higher expression of MNK2 in cancer tissues (P < 0.001; Fig. 1a). The gene discussed is MKNK2; the disease is non-small cell lung carcinoma.
