Since it has been previously shown that mitochondrial dynamics, namely Drp1, play a crucial role in orchestrating lymphocyte chemotaxis and migration of metastatic breast cancer, we set out to establish if the Drp1 pro-fission protein overexpression correlated with a higher capability of migration in the oncocytic XTC.UC1 cell line[30,31]. The gene discussed is DNM1L; the disease is breast cancer.
