GLP-1R activity also promotes the transactivation of epidermal growth factor receptor (EGFR), which then signals through phosphoinositide 3-kinase (PI3K) and insulin receptor substrate-2 (IRS-2), and subsequently activates extracellular-signal-regulated kinase 1 and 2 (ERK1/2) and nuclear translocation of PKC to mediate -cell proliferation and differentiation (114)
As of September 2025, GLP-1 drugs were priced at nearly $1K per month, although these costs are expected to fall to as low as $350 or less due to price agreements between GLP-1 companies and the Trump administration
