After more than six years of research, the research team led by María Soengas, head of CNIO's Melanoma Group, showed that RAB7 acts as an orchestra director, determining the fate of melanoma cells: at high concentrations of RAB7, cellular autodigestion is very active, and this allows tumor cells to obtain energy, prevent the accumulation of toxic components and thus divide and proliferate; when RAB7 is reduced, cells use endosomes to recycle metastatic proteins, favouring their dispersal throughout the body.
