Several such critical yet sensitive molecular targets have been recognized, and their specific antagonists or inhibitors validated as potential therapeutics in preclinical models. Yet, majority of anticancer principles or therapeutics show limited success in the clinical translation. Thus, the need for the development of an effective therapeutic strategy persists. “Altered energy metabolism” in cancer is one of the earliest known biochemical phenotypes which dates back to the early 20th century. Illustration of the cooperativity between The German scientist, Otto Warburg and oncogenic events (blue wheel) and metabolic his team (Warburg, Wind, Negelein 1926; reprogramming (green wheel) in cancer Warburg, Wind, Negelein 1927) provided the progression (brown wheel). first evidence that the glucose metabolism Cover image by Shanmugasundaram of cancer cells diverge from normal cells. Ganapathy-Kanniappan This phenomenal discovery on deregulated glucose metabolism or cellular bioenergetics is frequently witnessed in majority of solid malignancies. Currently, the altered glucose metabolism is used in the clinical diagnosis of cancer through positron emission tomography (PET) imaging. Thus, the “deregulated bioenergetics” is a clinically relevant metabolic signature of cancer cells, hence recognized as one of the hallmarks of cancer (Hanahan and Weinberg 2011). Accumulating data unequivocally demonstrate that, besides cellular bioenergetics, cancer metabolism facilitates several cancer-related processes including metastasis, therapeutic Frontiers in Oncology and Frontiers in Pharmacology 2 October 2017 | Cancer Metabolism resistance and so on. Recent reports also demonstrate the oncogenic regulation of glucose metabolism (e.g. glycolysis) indicating a functional link between neoplastic growth and cancer metabolism. Thus, cancer metabolism, which is already exploited in cancer diagnosis, remains an attractive target for therapeutic intervention as well. The Frontiers in Oncology Research Topic “Cancer Metabolism: Molecular Targeting and Implications for Therapy” emphases on recent advances in our understanding of metabolic reprogramming in cancer, and the recognition of key molecules for therapeutic targeting. Besides, the topic also deliberates the implications of metabolic targeting beyond the energy metabolism of cancer. The research topic integrates a series of reviews, mini-reviews and original research articles to share current perspectives on cancer metabolism, and to stimulate an open forum to discuss potential challenges and future directions of research necessary to develop effective anticancer strategies. Acknowledgment I sincerely thank the Frontiers for providing the opportunity and constant support throughout the process of this research topic and eBook production. I gratefully acknowledge all the authors for their valuable contributions. Finally, I would like to thank my brother, Saravana Kumar, G.K., whose personal sacrifices and unflinching encouragement made my career in science possible. References Hanahan D, Weinberg RA. 2011.
