Cultured mammalian cells are the main workhorses for producing biologics. The performance of these cell culture processes, in terms of both productivity and product quality attributes, is significantly influenced by cellular metabolism. Glucose is the major carbon source for cellular biosynthesis and energy generation. We summarize here recent advances in our understanding of the regulation of glucose metabolism in cultured cells. The versatility of cells to sustain homeostatic states under widely varying environments is made possible by allosteric regulation of the metabolic network, interplay between the signaling pathways, and transcription factors. Understanding the regulation of metabolism holds the key to altering the metabolic regulatory circuit and implementing direct metabolic control over cell culture processes.
