Weight Loss During Obesity Provokes Asparaginase‐Associated Liver Steatosis and Endoplasmic Reticulum Stress

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Lean mice and DIO mice were fed either a low‐fat maintenance diet (MD) or a high‐fat obesogenic diet (OD) during pegylated asparaginase exposure. OD exacerbated asparaginase‐induced weight loss and modestly increased liver triglycerides and ER stress in lean mice.
