Additionally, KPNA2 was associated with tumorigenesis and cancer progression in CRC cells; high KPNA2 expression was associated with increased cell proliferation (p < 0.05), migration (p = 0.03), invasion (p = 0.001), and semisolid agar colony formation (p < 0.001).
Herein, to understand the essential role of KPNA2 protein complexes in cancer progression, we applied stable isotope labeling with amino acids in cell culture (SILAC)-based quantitative proteomic strategy combined with immunoprecipitation (IP) to investigate the differential KPNA2 protein complexes in lung adenocarcinoma cell lines with different invasiveness potentials.
The aim of the present study was to examine the role of KPNA2 in the proliferation and tumorigenicity of EOC cells, and its clinical significance in tumor progression.
Remarkably, these individual effects of KPNA2 overexpression on proliferation, cell-matrix adhesion and migration resulted in an increased colony spreading of benign MCF10A breast cells and malignant MCF7 tumor cells (P<0.001), which is a hallmark of cancer progression.
