Abstract

Abstract

En 中文
Animal models of prediabetes (Pre-DM) are essential for studying metabolic disease and testing therapies, yet high-fat diet (HFD) and HFD-plus-streptozotocin (STZ) protocols vary in feeding duration, STZ dose, and diagnostic criteria and rarely account for sex. We compared five protocols in male and female C57BL/6J mice to find the best balance of duration, cost, and phenotypic stability and to characterize how HFD and HFD-STZ differ in their effects on glucose and lipid metabolism.
