Application of Virtual Twin PBPK Models in Individuals with Obesity via CYP3A4 Phenotyping Using Endogenous Biomarker Data

Clinical Pharmacology &Therapeutics, EarlyView.
Plasma 4β‐hydroxycholesterol (4β‐OHC) normalized for the levels of its parent cholesterol (4β‐OHC/C) is an endogenous biomarker for hepatic CYP3A4. This study evaluated CYP3A4 activity longitudinally in individuals while their obesity status was changing. 4β‐OHC/C was measured pre‐surgery (n = 54) and 2 years after Roux‐en‐Y gastric bypass (n = 30) and

Cholesterol 25-hydroxylation activity of CYP3A

Journal of Lipid Research, 2011
To date, many studies have been conducted using 25-hydroxycholesterol, which is a potent regulator of lipid metabolism. However, the origins of this oxysterol have not been entirely elucidated. Cholesterol 25-hydroxylase is one of the enzymes responsible

27-Hydroxycholesterol Promotes the Transfer of Astrocyte-Derived Cholesterol to Neurons in Co-cultured SH-SY5Y Cells and C6 Cells

Frontiers in Cell and Developmental Biology, 2020
Abnormality in cholesterol homeostasis in the brain is a feature of Alzheimer’s disease (AD). 27-Hydroxycholesterol (27-OHC) has been identified as a possible biomarker of AD, but its effects on cholesterol metabolism have not been fully characterized ...

A phase 3, randomized clinical trial of soticlestat as adjunctive therapy for Lennox–Gastaut syndrome

Epilepsia, EarlyView.
Soticlestat as adjunctive therapy for Lennox–Gastaut syndrome. Abstract Objective There remains a need for new treatments for Lennox–Gastaut syndrome (LGS), a developmental and epileptic encephalopathy with a heterogenous patient population that often requires polytherapy. The phase 3, randomized SKYWAY study (NCT04938427) investigated the efficacy and

Changes in the gut microbiome during fasting‐induced molting and its effects on gut–liver function

iMetaOmics, EarlyView.
During fasting, harmful microbiota and metabolites rise, triggering intestinal injury and activation of the TGF‐β signaling pathway, which enhances intestinal stem cell proliferation. Concurrently, hepatic function declines, indicated by increased hepatic and serum bile acids and upregulation of the non‐classical bile acid synthesis pathway.

Lovastatin fails to improve motor performance and survival in methyl-CpG-binding protein2-null mice

eLife, 2016
Previous studies provided evidence for the alteration of brain cholesterol homeostasis in 129.Mecp2-null mice, an experimental model of Rett syndrome. The efficacy of statins in improving motor symptoms and prolonging survival of mutant mice suggested a ...

Biomimetic mineralization‐inspired formulation‐adjuvant integrated circRNA nanovaccine against COVID‐19

Interdisciplinary Medicine, EarlyView.
Inspired by the role of Mg2+ in stabilizing RNA secondary structures, we developed a one‐pot biomimetic mineralization method for synthesizing a circular RNA‐based nanovaccine (circRNA@FAiNVac) that integrates formulation and adjuvant functions. This nanovaccine exhibits potent immunostimulatory activation enabling multimodal immune responses and ...

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

Pest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.
