(A) Transcriptional and post-translational regulation of acetyl-CoA metabolic enzymes. (B) Impact of oncogenic, microenvironmental and systemic metabolic factors on regulation of acetyl-CoA metabolic enzymes (red, signals associated with oncogenic signaling, high nutrient availability and fatty acid synthesis; green, signals associated with high lipid availability and fatty acid oxidation, and may be linked to obesity-related cancers; blue, signals associated with nutrient stress-inducing adaptation within the tumor microenvironment, which may include fatty acid oxidation or fatty acid synthesis depending on the context). Each of these adaptations may support tumor growth and/or facilitate survival within the tumor microenvironment.
