Cancer cell energy metabolism

"Cancer cell energy metabolism" refers to the collection of biochemical processes by which cancer cells acquire and utilize nutrients for ATP production and biosynthesis. Unlike most normal cells that primarily rely on mitochondrial oxidative phosphorylation for efficient ATP generation, many cancer cells preferentially use aerobic glycolysis—a phenomenon known as the Warburg effect—where glucose is converted to lactate even in the presence of oxygen[1]. This shift supports rapid proliferation by providing intermediates for biosynthetic pathways and maintaining redox balance[2]. However, cancer cells retain metabolic flexibility; they can also utilize glutaminolysis and other anaplerotic reactions to fuel the tricarboxylic acid cycle when needed[2]. The regulation of these pathways is influenced by oncogenes, tumor suppressors, hypoxic microenvironments, mitochondrial mutations, and tissue context[1][2]. Because "cancer cell energy metabolism" encompasses multiple molecular targets rather than a single defined entity such as a receptor or enzyme—and because it describes a cellular process—it is not considered a canonical therapeutic target itself but rather an area comprising many potential molecular targets. **Note:** This entry does not correspond to a singular molecule/receptor but instead describes an entire class of cellular processes. For structured data purposes requiring specificity at the level of molecules/targets suitable for drug development databases or ontologies ("receptor", "enzyme", etc.), this entry should be flagged as incorrect/incomplete.
