Suitability of Adenosine Derivatives in Improving the Activity and Stability of Cytochrome c under Stress: Insights into the Effect of Phosphate Groups

The Journal of Physical Chemistry B, 2023
It is well known that adenosine and its phosphate derivatives play a crucial role in biological phenomena such as apoptosis and cell signaling and act as the energy currency of the cell. Although their interactions with various proteins and enzymes have been described, the focus of this work is to demonstrate the effect of the phosphate group on the ...

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

FEBS 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 ...

Functional interference (crosstalk) between gut microbiome, proteolysis, apoptosis and muscle hypertrophy: Role of resistance training and supplement [PDF]

Journal of Exercise & Organ Cross Talk
Primary objective of this study was to examine the interplay between grip strength, a functional marker of hypertrophy, and its connection to the Firmicutes to Bacteroidetes ratio in the gut microbiome. Twenty-five male Wistar rats were divided into five

Adenosine triphosphate as a modulator of protein interactions and stability

FEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Yeast cytochrome c peroxidase. Coordination and spin states of heme prosthetic group.

Journal of Biological Chemistry, 1987
Electronic absorption and electron paramagnetic resonance (EPR) spectroscopic examinations revealed that a freshly prepared cytochrome c peroxidase (CCP) contains a penta-coordinated high spin ferric protoheme group. The penta-coordinated high spin state of fresh CCP is maintained in a remarkably wide range of pH (4-8).

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Pentamycin Biosynthesis in Philippine Streptomyces sp. S816: Cytochrome P450-Catalyzed Installation of the C-14 Hydroxyl Group [PDF]

ACS Chemical Biology, 2019
ABSTRACT Pentamycin is a polyene antibiotic, registered in Switzerland for the treatment of vaginal candidiasis, trichomo-niasis and mixed infections. Chemical instability has hindered its wide-spread application and development as a drug. Here we report the identification of Streptomyces

Real‐World Longitudinal Data on the Impact of Hydroxychloroquine Blood Level Monitoring on Lupus Outcomes: Results of a Prospective Longitudinal Cohort Study

Arthritis Care &Research, EarlyView.
Objective Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), but the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to identify clinical factors that predict ...

Maternal hypoxia increases hippocampal cell susceptibility to ischemia after middle cerebral artery occlusion in rat offspring

Folia Neuropathologica, 2017
Introduction : Maternal hypoxia induces an adverse uterine environment and may induce long-term effects in offspring. This study investigated whether maternal hypoxia increases hippocampal cell vulnerability and exacerbates neurological impairments in ...
