Melanoma causes the majority of deaths related to skin cancer. This cancer follows a classic progression, which is subdivided on the basis of cellular penetration. In invasive cancers, metabolic reprogramming is associated with the physiopathology of neoplastic cells. Metabolic reprogramming affects ATP production by the down-regulation of OXPHOS, which happens in the inner mitochondrial membrane. Many studies have shown that tumor cells-metabolic reprogramming is triggered by ROS production, which is generated by mitochondrial complexes and critical for HIF1± stabilization. Furthermore, ROS damages mtDNA and those mutations were associated with development of a metastatic potential. Little is known about mtDNA variations and their consequences on tumorigenesis. Previous results from our group have shown increased mitochondrial genome instability in colorectal adenoma and adenocarcinoma. Interestingly, different genic mitochondrial complexes were affected in each tissue, which suggests distinct roles of the mitochondrial complexes on colorectal tumorigenesis. Melanoma cell lines from different stages of progression (Radial Growth Phase, Vertical Growth Phase and Metastatic Melanoma) are excellent experimental models to evaluate the mitochondrial genome instability and their consequences on energetic metabolism alteration. Taken together, the main goal of this study is to investigate if the mitochondrial genome instability promotes metabolic reprograming on Melanoma progression. (AU)
