Cholesterol‐Mediated Metabolic‐mechanotransductive Crosstalk Orchestrates Castration Resistance in Prostate Cancer

open access: yesAdvanced Science, EarlyView.
Full androgen deprivation (FAD) induces paracrine cholesterol in prostate cancer that drives the polarization of cancer‐associated fibroblasts (CAFs) and subsequent elevated matrix stiffness. Matrix stiffness in turn potentiates tumor cell survival under FAD pressure via dual mechanotransductive activation of the IRE1α‐XBP1s stress‐response axis ...

Multiplexed Tandem Mass Spectrometry Imaging Enables Large‐Scale Isomer Mapping and Annotation in Tissues

open access: yesAngewandte Chemie, Volume 138, Issue 20, 11 May 2026.
Parallel mass spectrometry imaging acquires high mass resolution and tandem mass spectrometry images from 108 isolation windows in a single run. Spatial similarity networking clusters product ions by spatial distribution, enabling annotation of isomers and isobars as demonstrated for phospholipids and oxidized cholesterol in mouse and human brain ...

Pharmacokinetic profiling of imatinib in relation to CYP3A4 activity in leukaemia patients

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Imatinib pharmacokinetics exhibit large interindividual variability because of differences in CYP3A4 activity—the main imatinib‐metabolizing enzyme. While therapeutic drug monitoring is effective, it requires steady‐state conditions and frequent sampling.

A panel of altered blood oxysterols in patients with mild cognitive impairment: A novel combined diagnostic marker

open access: yesPharmacological Research
Perturbed cholesterol metabolism may play an important role in the development of dementia and its preclinical stage, mild cognitive impairment (MCI). Oxysterols, the metabolites generated during cholesterol oxidation, also appear to be risk factors for ...

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

open access: yesClinical 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

Changes in brain oxysterols at different stages of Alzheimer's disease: Their involvement in neuroinflammation

open access: yesRedox Biology, 2016
Alzheimer's disease (AD) is a gradually debilitating disease that leads to dementia. The molecular mechanisms underlying AD are still not clear, and at present no reliable biomarkers are available for the early diagnosis.

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

open access: yesInterdisciplinary 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 ...

Decoding Undesirable Inflammatory Responses of Nucleic Acid‐Delivering Lipid Nanoparticles

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
Lipid nanoparticles (LNPs) enable efficient nucleic acid delivery, but their immunogenicity is a double‐edged sword. This review explores LNP‐driven innate and adaptive immunity, covering lipid components, endosomal escape, and nucleic acid sensing.

Metabolic Fingerprinting of Urine Reveals Metabolite Changes in Women With Breast Cancer

open access: yesCancer Medicine, Volume 15, Issue 6, June 2026.
This study uses metabolomics to compare urine, plasma and serum metabolite profiles across breast cancer, benign breast disease, symptomatic and healthy controls. Significant metabolic differences—especially in amino acids—were found between BC and other groups, with moderate correlations across biofluids, suggesting potential for non‐invasive BC ...

CYP46A1‐Targeted Treatment Alleviates Long‐Term White Matter Injury Following Traumatic Brain Injury by Promoting Cholesterol Metabolic Clearance and Remyelination

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
Our findings demonstrate that CYP46A1 plays a critical role in regulating cholesterol homeostasis in microglia and that the targeting of CYP46A1 may offer a viable therapeutic approach for traumatic brain injury (TBI). The CYP46A1 activator Efavirenz reduces white matter damage by increasing the levels of the cholesterol metabolite 24OHC, thereby ...
