Our study supports the previous finding that overexpression of Cluster 1 genes in several cancer including NSCLC and associated with poor overall survival such as: KIF2C (73), KIF4A (11, 74), and KIF11 (75) which are kinesin family members of motor proteins regulating the cell mitosis through faithful chromosome condensation and segregation (76). This evidence concerns the gene KIF11 and non-small cell lung carcinoma.
