Aspartic Protease Inhibition Induces Proteomic Remodeling in Paracoccidioides brasiliensis

PROTEOMICS, EarlyView.
ABSTRACT Paracoccidioidomycosis (PCM) is a major systemic mycosis in Latin America caused by Paracoccidioides brasiliensis, yet the contribution of aspartic proteases to fungal physiology and pathogenicity remains poorly understood. Here, we employed data‐independent acquisition (DIA)‐based quantitative proteomics to investigate the impact of pepstatin

A universal metabolite repair enzyme removes a strong inhibitor of the TCA cycle

Nature Communications
A prevalent side-reaction of succinate dehydrogenase oxidizes malate to enol-oxaloacetate (OAA), a metabolically inactive form of OAA that is a strong inhibitor of succinate dehydrogenase. We purified from cow heart mitochondria an enzyme (OAT1) with OAA

Dendritic Cell α‐Ketoglutarate Regulates Tfh Polarization in Allergy

Allergy, EarlyView.
Allergen induces a dendritic cell metabolism shift toward glutaminolysis with α‐ketoglutarate as a regulator of Tfh subset polarization. Glutaminolysis is required for DC allergen uptake, co‐stimulatory molecule expression, and CLR expression. Modulation of glutaminolysis, JmjD3 histone demethylation, or HIF‐1α degradation alters Tfh polarization and ...

The intracellular localization of malate dehydrogenase isoenzymes in Pisum arvense roots

Acta Societatis Botanicorum Poloniae, 2014
Mitochondria and plastids were isolated from Pisum arvense root cells by sucrose density gradient centrifugation. The individual subcellular fractions so obtained were subjected to isoelectric focusing on cellulose acetate strips.

Shared dysregulation of complement and phosphorylation pathways in the cerebrospinal fluid of encephalitis, Aicardi–Goutières syndrome, and autism

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To identify shared and disorder‐specific molecular alterations across encephalitis, Aicardi–Goutières syndrome (AGS), and autism spectrum disorder (ASD) using cerebrospinal fluid (CSF) proteomics. Method In this cross‐sectional case–control study, mass‐spectrometry‐based proteomics was performed on archived CSF samples collected between ...

Dapagliflozin Alters Plasma Metabolome in Patients With Type 1 Diabetes During Ketosis

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Use of sodium‐glucose cotransporter 2 inhibitors (SGLT2i) in patients with type 1 diabetes (T1D) is limited by increased risk of ketoacidosis. We aimed to determine metabolic pathways affected by SGLT2i treatment in adults with T1D during ketosis induced by insulin withdrawal.

Common pathways and outliers in glucose catabolism across Trypanosomatidae

The FEBS Journal, EarlyView.
Trypanosomatid parasites, including Trypanosoma sp., Leishmania sp., Phytomonas sp., and Vickermania sp., share a common motif: a metabolism built around the glycosome, a unique peroxisome‐derived organelle housing the first steps of glycolysis. Yet, these organisms have evolved remarkably diverse strategies to catabolize glucose, excreting distinct ...

Energetic dysregulations in psychotic disorders: Targets for new therapeutics

The FEBS Journal, EarlyView.
The present review synthesizes literature documenting aberrant energy production and use, specifically related to mitochondrial and redox dysregulation, in psychotic disorders. Findings from different levels of investigation—genetic, cellular, and in vivo imaging—converge on aberrant energy metabolism as a hallmark of psychotic disorders.

Metabolic Profiling of Circulating and Tumour‐Infiltrating T Cells Uncovers Bioenergetic Checkpoints Linked With Immune and Clinical Skewing in Melanoma Patients

Immunology, EarlyView.
In this study, we revealed the disturbed metabolic status of circulating and tumour‐infiltrating CD4+ and CD8+ T cells in melanoma patients through targeted metabolomic and lipidomic (on sorted subsets) and at single cell level using the SCENITH method.

Comprehensive Profile of Acute Mitochondrial Dysfunction in a Preclinical Model of Severe Penetrating TBI

Frontiers in Neurology, 2019
Mitochondria constitute a central role in brain energy metabolism, and play a pivotal role in the development of secondary pathophysiology and subsequent neuronal cell death following traumatic brain injury (TBI).
