Abstract:
Objective To explore the relationship between mitochondrial DNA deletion and malignant phenotypes of human lung cancer cells. Methods Two rho? derivatives of 95C and 95D were generated by treating the cultured cells with ethidium bromide. Agarose colony formation assays and Transwell invasion assays were carried out to detect the phenotypes of colony formation and invasiveness of the cultured cells, respectively. Cell growth was determined by MTT. Results The partially mtDNA-deleted cells exhibited stronger capacity of colony formation and invasiveness, and faster growth rates than their respective parental cell lines. Conclusion Mitochondrial DNA deletion might play a role in the formation of malignant phenotypes of human lung cancer.
