Abstract :
Cancer cells exhibit profound metabolic reprogramming to support uncontrolled growth, survival, and therapy
resistance. In addition to a shift toward aerobic glycolysis, tumors display increased dependence on amino acids such as
glutamine, serine, methionine, and cysteine, essential for biosynthesis, redox balance, and epigenetic regulation. Lipid
metabolism, particularly fatty acid oxidation and lipolysis, is also upregulated, with key enzymes like ATP-citrate lyase
(ACLY) and acyl-CoA synthetase short-chain family member 2 (ACSS2) facilitating acetyl-CoA production, which fuels
histone acetylation and chromatin remodeling. Importantly, mitochondrial metabolism plays a pivotal role in supporting
both bioenergetic and epigenetic demands, linking mitochondrial function with gene regulation. Nucleotide synthesis, both
de novo and salvage, is enhanced in tumors and influenced by oncogenes and stress responses, contributing to genomic
instability and metastasis. These integrated metabolic and epigenetic adaptations present promising therapeutic
vulnerabilities. Targeting key metabolic enzymes and mitochondrial-epigenetic interfaces may function with gene
regulation. Nucleotide synthesis, both de novo and salvage, is enhanced in tumors and influenced by oncogenes and stress

Cancer cells exhibit profound metabolic reprogramming to support uncontrolled growth, survival, and therapy

glutamine, serine, methionine, and cysteine, essential for biosynthesis, redox balance, and epigenetic regulation. Lipid
metabolism, particularly fatty acid oxidation and lipolysis, is also upregulated, with key enzymes like ATP-citrate lyase

histone acetylation and chromatin remodeling. Importantly, mitochondrial metabolism plays a pivotal role in supporting
both bioenergetic and epigenetic demands, linking mitochondrial function with gene regulation. Nucleotide synthesis, both
de novo and salvage, is enhanced in tumors and influenced by oncogenes and stress responses, contributing to genomic
