Overexpression of KIAA0101 Promotes the Progression of Non-small Cell Lung Cancer

Lung cancer is the leading cause of cancer related death worldwide, with a continue-rising incidence. The proliferating cell nuclear antigen binding protein KIAA0101 is highly expressed in various types of cancer, including non-small cell lung cancer (NSCLC). However, its biological role and underlying mechanisms in NSCLC remains unclear. We downloaded KIAA0101 mRNA and clinical data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO), and verified the KIAA0101 expression by conducting experiments of immunochemistry (IHC), immunofluorescence (IF), quantitative real-time PCR (qRT-PCR) and western-blot. Functional experiments were performed to explore the biological roles in vitro and in vivo. The results showed that KIAA0101 was overexpressed in NSCLC tissues and cell lines. High KIAA0101 expression was associated with high T stage, nodal invasion, advanced tumor stage, and poor overall survival (P
