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 ...

Effect of ultrafiltration on the antioxidant activity of alcalase-hydrolyzed catfish (Clarias gariepinus) protein [PDF]

open access: yesBIO Web of Conferences
Catfish (Clarias sp.) is one of Indonesia's leading aquaculture commodities with potential utilization as a source of functional protein. Protein hydrolysis using alcalase enzyme can generate bioactive peptides with antioxidant activity.

Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound

open access: yesFEBS Open Bio, EarlyView.
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

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 ...

Effect of hydrolysing condition on antioxidant activity of protein hydrolysate from Crucian carp (Carassius carassius) [PDF]

open access: yesPizhūhish va Nuāvarī dar ̒Ulūm va Sanāyi̒-i Ghaz̠āyī, 2014
In this study protein hydrolysate was produced from the crucian carp using Alcalase 2.4L. The effect of temperature (40, 45, 50 and 55°C), time (60, 90, 120, 150, 180 & 210min) and enzyme/substrate (Protein) at ratio of (30, 60 and 90 Anson unit), on ...

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Gene-regulatory activity of alpha-tocopherol. [PDF]

open access: yes, 2010
Vitamin E is an essential vitamin and a lipid soluble antioxidant, at least, under in vitro conditions. The antioxidant properties of vitamin E are exerted through its phenolic hydroxyl group, which donates hydrogen to peroxyl radicals, resulting in ...

The Optimization of Hydrolyzed Protein Production with High Anti-Oxidation Ability from Sesame Meal by Response Surface Methodology [PDF]

open access: yesPizhūhish va Nuāvarī dar ̒Ulūm va Sanāyi̒-i Ghaz̠āyī, 2019
The purpose of this study was to produce a hydrolyzed protein from sesame seed meal using response surface methodology (RSM).The sesame meal protein is a low-value product, often used for feeding animals, but it can be hydrolyzed to protein hydrolysate ...

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

open access: yesFEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...
