ProteomicsSubcellular proteomics combined with bioenergetic phenotyping reveals protein biomarkers of respiratory insufficiency in the setting of compromised mitochondrial DNA repair.
The mitochondrial mutator mouse is a well-established model of premature aging in which a progeroid phenotype is driven by the accumulation of somatic mtDNA mutations. Despite evidence of bioenergetic disruption within the cardiac mitochondria, there is little information about the underlying change...

ProteomicsMitochondrial content normalization using mass spectrometry allows quantitative evaluation of intrinsic bioenergetic efficiency and the underlying proteome across mouse organs.
To separate global changes to metabolism from intrinsic mitochondrial remodeling, investigators commonly use isolated mitochondrial preparations obtained through differential centrifugation. This simple process has been reliably implemented in a variety of tissues to produce intact, functional mitoc...

ProteomicsComprehensive respiratory phenomics across multiple models of mitochondrial protein hyperacylation reveals a paradoxically marginal impact on bioenergetics
Acyl CoA metabolites derived from catabolism of carbon fuels can react with lysine residues of mitochondrial proteins, giving rise to a large family of post-translation modifications (PTMs). Mass spectrometry-based detection of thousands of acyl-PTMs scattered throughout the proteome has established...

ProteomicsMitochondrial proteome of human leuekmia.
Proteome characterization of isolated mitochondria samples prepared from three commonly used acute leukemia cell lines (HL-60, KG-1, MV-4-11). Data were compared to isolated mitochondria prepared from peripheral blood mononuclear cells (PBMC), isolated from healthy human subjects.

ProteomicsVincristine resistance reshapes sphingolipid composition and promotes mitochondrial complex I deficiency in acute myelogenous leukemia
Modifications in sphingolipid (SL) metabolism and mitochondrial bioenergetics are key factors implicated in cancer cell response to chemotherapy, including chemotherapy resistance. Vinca alkaloids such as vincristine (VCR), widely used in cancer treatment, are no exception, as their beneficial actio...

ProteomicsInterventional- and amputation-stage muscle proteomes in the chronically threatened ischemic limb
Background: Despite improved surgical approaches for chronic limb threatening ischemia (CLTI), amputation rates remain high and contributing tissue-level factors remain unknown. Objective: The purpose of this study was twofold: 1) to identify differences between the healthy adult and CLTI limb mu...

ProteomicsThe exercise-regulated skeletal muscle phosphoproteome
Four healthy male volunteers (age: 24 - 27; BMI: 24.2 - 25.9 kg/m2) underwent a single bout of high-intensity bicycle exercise reaching a VO2 max approximately 95% with blood samples and muscle biopsies taken immediately pre- and post-exercise. Subjects reached 95% VO2 max in approximately 9 to 12 m...
