LncRNA‐MEG3 Regulates Muscle Mass and Metabolic Homeostasis by Facilitating SUZ12 Liquid–Liquid Phase Separation

Advanced Science, EarlyView.
This study has identified lncRNA‐MEG3 as a key regulator of muscle mass, promoting slow‐twitch muscle fibers and preventing muscle atrophy. By stabilizing the SUZ12/PRC2 complex through liquid–liquid phase separation (LLPS), lncRNA‐MEG3 influences mitochondrial function and lipid metabolism.

Myeloid p38 activation maintains macrophage–liver crosstalk and BAT thermogenesis through IL‐12–FGF21 axis

Hepatology, EarlyView., 2022
Physiological activation of myeloid p38 controls macrophage IL‐12 production and crosstalk to the liver by modulating hepatic FGF21, and subsequently, brown adipose tissue thermogenesis during obesity Abstract Obesity features excessive fat accumulation in several body tissues and induces a state of chronic low‐grade inflammation that contributes to ...

FABP4 as a Mediator of Lipid Metabolism and Pregnant Uterine Dysfunction in Obesity

Advanced Science, EarlyView.
Obesity during late pregnancy contributes to uterine smooth muscle dysfunction, but the underlying mechanisms are unclear. This study identifies fatty acid binding protein 4 (FABP4) as a key player in the process, mediating excessive fatty acid uptake, lipid accumulation, and mitochondrial dysfunction in myometrial cells. FABP4 could be a novel uterine

RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease

Hepatology, EarlyView., 2022
RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease. Abstract Background and Aims Receptor‐interacting protein kinase 3 (RIPK3) mediates NAFLD progression, but its metabolic function is unclear. Here, we aimed to investigate the role of RIPK3 in modulating mitochondria function, coupled with lipid droplet (LD)

Spatiotemporal Super‐Resolution Imaging of Lipid Metabolism Dynamics in Physiological/Pathological Conditions

Angewandte Chemie, EarlyView.
A novel polarity‐sensitive fluorescent probe was developed for the selective targeting of lipid droplets, enabling precise visualization and quantification of lipid metabolism disorders using an integrated STED‐FLIM platform. This probe allows accurate monitoring of lipid metabolism in cellular and pathological contexts, such as atherosclerosis ...

Calpain‐2‐Mediated Endothelial Focal Adhesion Disruption in Thoracic Aortic Dissection

Advanced Science, EarlyView.
The elevated expression of Capn2 in endothelial cells activates focal adhesion signaling by cleaving Talin1 and assembling Itgav, which compromises the integrity of the endothelial barrier and induces vascular inflammation. Inhibition of calpain through both pharmacological and transgenic approaches has effectively suppressed the onset and progression ...

Emergence of highly profibrotic and proinflammatory Lrat+Fbln2+ HSC subpopulation in alcoholic hepatitis

Hepatology, EarlyView., 2022
Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

Xenotransplantation of human fetal adipose tissue: a model of in vivo adipose tissue expansion and adipogenesis

Journal of Lipid Research, 2014
Obesity during childhood and beyond may have its origins during fetal or early postnatal life. At present, there are no suitable in vivo experimental models to study factors that modulate or perturb human fetal white adipose tissue (WAT) expansion ...

Crown-Like Structures in Breast Adipose Tissue: Finding a 'Needle-in-a-Haystack' using Artificial Intelligence and Collaborative Active Learning on the Web [PDF]

arXiv
Crown-like structures (CLS) in breast adipose tissue are formed as a result of macrophages clustering around necrotic adipocytes in specific patterns. As a histologic marker of local inflammation, CLS could have potential diagnostic utility as a biomarker for breast cancer risk.
