We introduce neutron-encoded (NeuCode) amino acid labeling of mice as a strategy for multiplexed proteomic analysis in vivo. Using NeuCode we characterize an inducible knock-out mouse model of Bap1, a tumor suppressor and deubiquitinase whose in vivo roles outside of cancer are not well established. NeuCode proteomics revealed altered metabolic pathways following Bap1 deletion, including profound elevation of cholesterol biosynthetic machinery coincident with reduced expression of gluconeogenic and lipid homeostasis proteins in the liver. Bap1 loss increased pancreatitis biomarkers and reduced expression of mitochondrial proteins. These alterations accompany a metabolic remodeling with hypoglycemia, hypercholesterolemia, hepatic lipid loss, and acinar cell degeneration. Liver-specific Bap1-null mice present with fully penetrant perinatal lethality, severe hypoglycemia and hepatic lipid deficiency. This work reveals Bap1 as a metabolic regulator in the liver and pancreas, and establishes NeuCode as a reliable proteomic method for deciphering in vivo biology. Baughman et al. use NeuCode in vivo labeling for multiplexed quantitation in mouse tissues. Using this approach, coupled with multiple genetically engineered mouse models, they demonstrate a role for Bap1 in maintaining metabolic homeostasis in the liver and pancreas.
