Firstly, there were several common pathways that were also enriched in the kinetic study at T30, such as central carbon metabolism in cancer; linoleic acid metabolism; regulation of lipolysis in adipocytes; phenylalanine, tyrosine, and tryptophan biosynthesis; neuroactive ligand–receptor interaction; valine, leucine, and isoleucine biosynthesis; and glucagon signaling pathway (Figure 6c). Here, GCG is linked to cancer.
