Turning off insulin signals in the back part of the liver doesn’t make blood sugar go up, even when the mouse eats a high-fat diet.
Scientific Claim
Disrupting insulin signaling in pericentral hepatocytes does not impair systemic glucose regulation in mice fed a high-fat diet.
Original Statement
“PC-insulin resistance reduced HFD-induced pericentral steatosis while preserving normal glucose homeostasis.”
Evidence Quality Assessment

Can make definitive causal claims
Assessment Explanation
Direct measurement of glucose homeostasis under controlled conditions supports a definitive conclusion about the absence of glucose dysregulation in this specific context.

286-OR: Spatial Regulation of Glucose and Lipid Metabolism by Hepatic Insulin Signaling
When scientists blocked insulin signaling only in a specific part of the liver, the mice still kept their blood sugar normal—even on a high-fat diet—meaning that part of the liver isn’t needed to control blood sugar.
