Recombinant glycoproteins produced in mammalian cells are clinically indispensable drugs used to treat a broad spectrum of diseases. Their bio-manufacturing process is laborious, time consuming, and expensive. Investment in expediting the process and reducing its cost is the subject of continued research. The PI3K/Akt/mTOR signaling pathway is a key regulator of diverse physiological functions such as proliferation, global protein, and lipid synthesis as well as many metabolic pathways interacting to increase secretory capabilities. In this review we detail various strategies previously employed to increase glycoprotein production yields via either genetic or pharmacological over-activation of the PI3K/Akt/mTOR pathway, and we discuss their potential and limitations.
