Abstract
In recent years we have witnessed mounting evidences on how a normal cell changes its cellular signaling and metabolic pathways to become highly proliferative cancer cell. Since mitochondrion is a major hub of energy production and several metabolic pathways, it is taking the center stage in defining alterations in energy homeostasis and metabolic rerouting of cancer cell proliferation. Similarly, mutations in the mitochondrial genome in cancer are providing new insights on how these mutations affect mitochondrial functions and change the oncogenic signaling and apoptosis mechanism. In this review, we will summarize these important mitochondrial mechanisms that contribute significantly in the progression of cancer. Further therapeutic approaches targeted to these altered mitochondrial mechanism in cancer are discussed. This review is a part of special issue on Mitochondria: implications in human health and diseases.
