Biological Mechanisms Underlying the Ultraviolet Radiation-Induced Formation of Skin Wrinkling and Sagging I: Reduced Skin Elasticity, Highly Associated with Enhanced Dermal Elastase Activity, Triggers Wrinkling and Sagging

open access: yesInternational Journal of Molecular Sciences, 2015
The repetitive exposure of skin to ultraviolet B (UVB) preferentially elicits wrinkling while ultraviolet A (UVA) predominantly elicits sagging. In chronically UVB or UVA-exposed rat skin there is a similar tortuous deformation of elastic fibers together

Advanced Nanoparticle Therapeutics for Targeting Neutrophils in Inflammatory Diseases

open access: yesAdvanced Healthcare Materials, EarlyView.
This review highlights recent advances in nanoparticle‐based strategies to modulate neutrophil activity in inflammatory diseases. By targeting inflammatory neutrophils, NET formation, and neutrophil apoptosis or recruitment, these approaches aim to improve therapeutic precision.

Radioimmunoassay of Plasma Elastase

open access: yesExperimental Biology and Medicine, 1974
SummaryA radioimmunoassay system was developed for the measurement of canine elastase. The method is able to measure elastase in plasma in concentrations ranging from 0.1 to 2.0 μg/ml. No cross-reactivity was found with trypsin or chymo-trypsin. The elastase levels in canine plasma were measured during experimental pancreatitis. Within 15 min after the

Neutrophil Elastase Activates Protease-activated Receptor-2 (PAR2) and Transient Receptor Potential Vanilloid 4 (TRPV4) to Cause Inflammation and Pain*

open access: yesJournal of Biological Chemistry, 2015
Background: Proteases cleave protease-activated receptor-2 (PAR2), which activates transient receptor potential (TRP) ion channels to cause inflammation and pain.

Acod1 Promotes PAD4 Ubiquitination via UBR5 Alkylation to Modulate NETosis and Exert Protective Effects in Sepsis

open access: yesAdvanced Science, EarlyView.
In this study, Acod1 knockout in CLP mice significantly increases peripheral blood NET levels, exacerbating inflammation, organ damage, and reducing survival. Further research shows that UBR5 interacts with PAD4, a key NET formation protein. Acod1/itaconate (ITA) enhances the enzymatic activity of UBR5 by alkylating the Cys2768 site, promoting the K48 ...

New Anti-Inflammatory 9,11-Secosterols with a Rare Tricyclo[5,2,1,1]decane Ring from a Formosan Gorgonian Pinnigorgia sp.

open access: yesMarine Drugs, 2016
Pinnigorgiols D (1) and E (2), two new 9,11-secosterols with a rearranged carbon skeleton, were isolated from a Taiwan gorgonian Pinnigorgia sp. The structures of these two compounds were elucidated on the basis of spectroscopic methods and were proven ...

Emodin Alleviates Sepsis‐Induced Multiorgan Damage by Inhibiting NETosis through Targeting Neutrophils BCL‐10

open access: yesAdvanced Science, EarlyView.
Emodin targets BCL‐10 to modulate the BCL‐10/MALT1 complex, thereby suppressing NF‐κB activation and significantly exerting multiorgan protective effects in sepsis. Abstract Sepsis is a life‐threatening condition caused by dysregulated host responses to infection, characterized by excessive inflammation and abnormal coagulation.

Discovery of New Eunicellins from an Indonesian Octocoral Cladiella sp.

open access: yesMarine Drugs, 2011
Two new 11-hydroxyeunicellin diterpenoids, cladieunicellin F (1) and (–)-solenopodin C (2), were isolated from an Indonesian octocoral Cladiella sp. The structures of eunicellins 1 and 2 were established by spectroscopic methods, and eunicellin 2 was ...

PP2Acα Deficiency in Vascular Smooth Muscle Cells Accelerates Aortic Aneurysm and Dissection by Regulating KLF4 Phosphorylation and Ubiquitination

open access: yesAdvanced Science, EarlyView.
Vascular smooth muscle cells (VSMCs)‐specific deficiency of PP2Acα exacerbates aortic aneurysm and dissection (AAD) by promoting phenotypic switching through AKT1‐mediated phosphorylation and stabilization of Kruppel‐like factor 4 (KLF4). Reduced PP2Acα enhances KLF4 ubiquitination resistance, suppressing VSMC contractile genes and accelerating aortic ...
