Ceramides: focus on obesity

Ожирение и метаболизм, 2020
It is generally known that obesity increases the risk of developing cardiovascular disease. A pathological increase in the mass of adipose tissue leads to a violation of the control of lipid accumulation at the molecular level, abnormal lipid metabolism ...

Early Radiation Therapy Response Assessment Using Multi‐Scale Photoacoustic Imaging

Advanced Science, EarlyView.
Tomographic and mesoscopic photoacoustics capture intratumoural features of radioresistance and response. ABSTRACT There is a critical unmet clinical need to identify biomarkers that predict and detect radiation therapy (RT) response in cancer. Using the unique capabilities of multi‐scale photoacoustic imaging (PAI) to depict tumor oxygenation and ...

TEAD1 Enhances Exosome Secretion and Promotes Exosome‐Mediated Tissue Regeneration

Advanced Science, EarlyView.
TEAD1 functions as a crucial molecular switch regulating exosome secretion in various cell types. TEAD1 enhances exosome secretion by upregulating key proteins associated with exosome secretion, including RAB11, CD9, and SNAP23. This study reveals a novel role for TEAD1 in regulating exosome secretion and tissue regeneration, particularly in diabetic ...

SR‐B1‐Mediated Transplacental Transfer of Hydrophobic Toxicants Disrupts Fetal Development During Barriergenesis

Advanced Science, EarlyView.
This study maps the spatiotemporal distribution of hydrophobic toxicants and endogenous metabolites in the developing placenta and fetus. By integrating mass spectrometry imaging with snRNA‐seq, we identify SR‐B1 as a key transporter driving early‐gestation xenobiotic transfer and reveal a critical exposure window associated with persistent fetal ...

Ceramide signaling in immunity: a molecular perspective

Lipids in Health and Disease
Ceramides are bioactive lipids that play a crucial role in cellular signaling and structural integrity (Nat Rev Mol Cell Biol 19:175-191, 2018). As members of the sphingolipid family, ceramides consist of a sphingoid base attached to a fatty acid (Annu ...

Dihydroceramide- and ceramide-profiling provides insights into human cardiometabolic disease etiology

Nature Communications, 2022
Among lipid classes, ceramides are linked to impaired cardiometabolic health. Here the authors report the association of specific ceramides and dihydroceramides on the risk of developing type 2 diabetes and or cardiovascular disease in a prospective ...

3D Bioprinted Fat‐Myocardium Model Unravels the Role of Adipocyte Hypertrophy in Atrial Dysfunction

Advanced Science, EarlyView.
A human‐derived 3D bioprinted fat–myocardium model is developed to investigate how adipocyte hypertrophy drives atrial dysfunction in obesity. Palmitate‐induced adipocyte hypertrophy promotes adipose dysfunction that impairs atrial cardiomyocyte metabolism and electrophysiology through both paracrine and direct interactions. This platform recapitulates

Cohort‐Scale Spatial Autocorrelation for Tumor Prediction in Mid‐Infrared Pathology and Spatial Biomarker Discovery Using MALDI Imaging Lipidomics

Advanced Science, EarlyView.
Computational annotation of various tissue types in heterogeneous samples such as colorectal cancer liver metastasis (CRLM) using spatial autocorrelation analysis on non‐destructive mid‐infrared (MIR) imaging data enabled correlative multimodal mass spectrometry imaging (MSI) for spatial investigation of lipid tumor marker candidates. The method can be
