CKS2 and lung adenocarcinoma: In the TCGA data, CKS2 expression level in lung adenocarcinoma was higher than that in normal tissues, and high CKS2 expression was associated with poor prognosis and malignant phenotype of lung adenocarcinoma, while silencing CKS2 expression significantly inhibited the proliferation and invasion of lung adenocarcinoma cells and promoted apoptosis (18).
