Rat liver chromatin phospholipids

, 1994
To shed light on the question whether the phospholipids present in chromatin are native or are due to contamination from nuclear membranes, we labeled the phospholipids of isolated nuclei and determined the amount of phospholipids (PL) and PL fatty acid ...

Effect of phospholipids and bile acids on cholesterol nucleation time and vesicular/micellar cholesterol in gallbladder bile of patients with cholesterol stones [PDF]

, 1993
Supersaturation and rapid nucleation of cholesterol in bile are of key importance in the pathogenesis of cholesterol gallstones. While the effects of bile acids and phospholipids on cholesterol saturation of bile have been extensively studied, their ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

The oily nucleus– role of phospholipids in genome biology: membrane-directed roles and signaling in the nucleoplasm

Cellular and Molecular Life Sciences
Phospholipids, widely known for their structural role in cellular membranes, are now also recognized to play pivotal roles in signal transduction, metabolism, and cellular homeostasis.

A Biomimetic Lubricant Captures Hyaluronic Acid In Situ to Regenerate Cartilage: From Bench to Bedside

Advanced Science, EarlyView.
(a) The outstanding lubricative properties of natural articular cartilage arise from a composite coating composed of HA, lubricin, and phospholipids at its surface. Notably, lubricin facilitates the enrichment of synovial HA onto cartilage surfaces, and HA complexes with phospholipids, a key component to maintain extremely low friction under high ...

ROS‐Responsive Nanobubbles for Dual‐Enhanced Ultrasound and Magnetic Resonance Imaging of Tumor Oxidative Stress

Advanced Science, EarlyView.
We report the development of biotinylated PEGylated bilirubin‐coated perfluoropentane (bt‐PEG‐BR@PFP) nanobubbles, a novel class of ROS‐activatable and dual‐modality contrast agents that amplify both ultrasound (US) and magnetic resonance imaging (MRI) signals in response to elevated ROS.

Synthesis of chromatin phospholipids

, 1987
The presence of a phospholipid fraction associated with chromatin has been demonstrated by biochemical technique in rat hepatocytes. The composition of this fraction determined by chromatography with respect to that of the nuclei is characterized by low ...

Hyperlipidemia Aggravates Alveolar Bone Loss via Periodontal Ligament Stem Cell Ferroptosis Through GSK3β Dependent Ubiquitin‐Mediated NRF2 Degradation

Advanced Science, EarlyView.
Lipid metabolic stress triggers ferroptosis in PDLSCs through the GSK3β/NRF2 pathway, thereby aggravating periodontal bone loss. Upregulated GSK3β promotes NRF2 ubiquitination and proteasomal degradation via β‐TrCP, suppressing NRF2 nuclear translocation and antioxidant target expression.

Photodynamic Priming and Minocycline Overcome Chemoresistance by Reprogramming the Pancreatic Tumor Immune Microenvironment In Vivo

Advanced Science, EarlyView.
Dual priming with minocycline and photodynamic priming reprograms the pancreatic tumor microenvironment to overcome chemoresistance. By suppressing DNA repair enzyme Tdp1, inducing photooxidative damage, and enhancing irinotecan delivery via light‐activated nanoencapsulation, this strategy remodels the tumor microenvironment and drives immune ...

NET‐DNA Activates the ANXA2/TMEM215/BiP Axis to Promote Mitophagy‐Mediated Anoikis Resistance in Endometriosis

Advanced Science, EarlyView.
NET‐DNA is enriched during early endometriotic lesion establishment and drives anoikis resistance by promoting an ANXA2–TMEM215–BiP axis. This pathway strengthens ER–mitochondria contacts, enhances PINK1/Parkin‐associated mitophagy, preserves mitochondrial homeostasis, and supports ectopic stromal cell survival, thereby facilitating lesion persistence ...
