Hyperinsulinemia can lead to downregulated insulin signaling through means such as inducing receptor degradation, altering phosphorylation patterns of insulin signaling effector molecules (e.g., IRS-1, Akt, PI3K) in target tissues or indirectly by promoting obesity (Shanik et al. 2008, Nolan & Prentki 2019, Johnson 2021). The gene discussed is AKT1; the disease is Obesity.
