From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Evaluation of oxidative status in iron deficiency anemia through total antioxidant capacity measured using an automated method

open access: yesTurkish Journal of Hematology, 2011
Objective: Oxidative stress, an increase in oxidants and/or a decrease in antioxidant capacity, is one of the potential biochemical mechanisms involved in the pathogenesis of iron deficiency anemia.

Peroxidative Index: A New Marker in Kidney Toxicity Induced by Mercury

open access: yes, 2017
Oxidative stress is an important molecular mechanism for kidney injury in mercury (Hg) poisoning. Usually, oxidative stress was measured by measuring the levels reactive oxygen species (ROS) and antioxidant enzymatic activity. In this present study, we proposed a new marker for oxidative stress in kidney toxicity induced by Hg.

A New Method for Judging Deterioration of Stored Garden Peas, an Index of Lipid Peroxidation

open access: yesBioscience, Biotechnology, and Biochemistry, 1995
The 1,3-diethyl-2-thiobarbituric acid (DETBA) method for measuring lipid peroxidation could discriminate slight differences in garden peas with outward deterioration hardly recognizable with the naked eye. The increase in DETBA values during storage of the garden peas was closely related to the change in surface color and the decrease in both ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

open access: yesFEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Comprehensive lipid tetrad index, atherogenic index and lipid peroxidation: Surrogate markers for increased cardiovascular risk in psoriasis

open access: yesIndian Journal of Dermatology, Venereology, and Leprology, 2015
Recently, the concept of "psoriatic march" has come to the fore, in which chronic cutaneous inflammation in psoriasis leads to systemic inflammation which, in conjunction with increased oxidative stress, triggers a cascade of events resulting in increased cardiovascular risk in patients with severe psoriasis.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

open access: yesFEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Longitudinal Assessment of Biomarkers in ALS: Discriminative Biomarkers for Disease Progression and Survival

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To assess the association and discriminative performance of serum biomarkers with clinical disease progression and survival in patients with amyotrophic lateral sclerosis (ALS). Methods This retrospective study, conducted at Houston Methodist Hospital, Houston, TX, used longitudinal serum samples collected between January 2018 and ...
