MetabolomicsRedox proteomics reveal a role for peroxiredoxinylation in stress protection.

The redox state of proteins is essential for their function and guarantees cell fitness. Peroxiredoxins protect cells against oxidative stress, maintain redox homeostasis, act as chaperones, and transmit hydrogen peroxide signals to redox regulators. Despite the profound structural and functional...

MetabolomicsRhythmic glucose metabolism regulates the redox circadian clockwork in human red blood cells (LC-MS)

Circadian clocks coordinate mammalian behaviour and physiology enabling organisms to anticipate 24-hour cycles. Transcription-translation feedback loops are thought to drive these clocks in most of mammalian cells. However, red blood cells (RBCs), which do not contain a nucleus, and cannot perfor...

MetabolomicsRhythmic glucose metabolism regulates the redox circadian clockwork in human red blood cells (GC-MS)

Circadian clocks coordinate mammalian behaviour and physiology enabling organisms to anticipate 24-hour cycles. Transcription-translation feedback loops are thought to drive these clocks in most of mammalian cells. However, red blood cells (RBCs), which do not contain a nucleus, and cannot perfor...

MetabolomicsMetabolomics profiling reveals changes in peptidoglycan and redox metabolism between ancient and modern Mycobacterium tuberculosis

Mycobacterium tuberculosis (Mtb), the cause of tuberculosis, kills over one million people worldwide each year. Mtb is classified into ten distinct lineages, each harboring unique genetic changes that influence its survival, virulence, and transmissibility. Although metabolism plays a cr...

MetabolomicsPhotosynthetic bioenergetic-redox restoration rejuvenates the aged muscle regenerative niche

Aging impairs muscle regeneration, but the key constraint remains unclear. Aged injured muscle fails to restore mitochondrial respiration, membrane potential, ATP/NADPH balance and redox control, forming a bioenergetic-redox bottleneck. To target this, we engineered CM-NTU-Ce, a C2C12 membrane-co...

MetabolomicsMulti-omics-identified StAPR3 enhances potato Cd tolerance and tuber quality via sulfur metabolism and glutathione redox homeostasis

Cadmium (Cd) in agricultural soils inhibits potato growth, disrupts tuber development, and causes Cd accumulation in edible tubers, threatening food safety. Here, we determined the EC50 of Cd in potato, which induced oxidative stress and chloroplast damage. Transcriptomic and metabolomic co-analy...

TranscriptomicsA binary redox control mode in gene expression and metabolism of plants
To analyze the impact of photosynthetic redox signals, light sources with spectral qualities that preferentially excite either Photosystem I (PSI light) or Photosystem II (PSII light) were used. The light sources have been described in (Fey et al., 2005). Strong reduction and oxidation signals were ...

MetabolomicsRhizosphere reprogramming by phosphate slag enhances glutathione-centered redox regulation and root development in tobacco

Background and aims: Phosphate slag, a by-product of phosphorus and steel production, is a potential soil amendment that improves nutrient availability and redox stability. However, how it reshapes the rhizosphere microbiome and metabolism to promote tobacco (Nicotiana tabacum L.) root developmen...

MetabolomicsMesenchymal stromal cells secretome restores bioenergetic and redox homeostasis in human proximal tubule cells after ischemic injury

BACKGROUND: Ischemia/reperfusion injury (IRI) is the leading cause of acute kidney injury (AKI). The current standard of care focuses on supporting kidney function, stating the need for more efficient and targeted therapies to enhance repair. Mesenchymal Stromal Cells (MSCs) and ...

MetabolomicsMetabolomics Analysis Identifies Glutamic acid and Cystine imbalances in COVID-19 Patients Without Comorbid Conditions. Implications on Redox Homeostasis and COVID-19 Pathophysiology

It is well known that the presence of comorbidities and age-related health issues may hide biochemical and metabolic features triggered by SARS-CoV-2 infection and other diseases associated to hypoxia, as they are by themselves chronic inflammatory conditions that may potentially disturb metaboli...
