Melatonin and cortisol exhibit different circadian rhythm profiles during septic shock depending on timing of onset: a prospective observational study

open access: yesAnnals of Intensive Care, 2018
Background Septic shock has been found to disrupt circadian rhythms. Moreover, timing of onset has been associated with different circadian profiles in experimental studies.

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

TREM2‐Mediated Cholesterol Efflux in Macrophages Inhibits Anti‐Tumor Immunity via Limitation of CD4+ T and NK Cells

open access: yesAdvanced Science, EarlyView.
Impaired anti‐tumor immunity is mediated by TREM2 + macrophages in non‐small cell lung cancer. TREM2 + macrophages prevent anti‐tumor immunity depending on the limitation of CD4 + T and NK cells. TREM2 promotes cholesterol efflux via ABCA1 to limit the production of CX3CL1 in macrophages.

Septic Shock in Pyogenic Liver Abscess: Clinical Considerations

open access: yesThe Korean Journal of Gastroenterology, 2016
Background : /Aims: Pyogenic liver abscess (PLA) is a life-threatening condition, despite advances in diagnostic technology and strategies for treatment. A strong predictor of mortality in this condition is septic shock.

Vitamin D Regulates Olfactory Function via Dual Transcriptional and mTOR‐Dependent Translational Control of Synaptic Proteins

open access: yesAdvanced Science, EarlyView.
Vitamin D (VitD) modulates olfactory function by remodeling dendrodendritic synapses in tufted cells through vitamin D receptor‐dependent transcriptional and translational mechanisms. VitD regulates synaptic protein translation partially via mTOR signaling.

Targeted Inhibition of CD74+ Macrophages by Luteolin via CEBPB/P65 Signaling Ameliorates Osteoarthritis Progression

open access: yesAdvanced Science, EarlyView.
This study identifies CD74⁺ macrophages as key drivers of synovial inflammation in osteoarthritis (OA). The flavonoid luteolin is predicted to inhibit this pathway by blocking Nuclear Factor Kappa‐light‐chain‐enhancer of Activated B cells (NF‐κB) signaling. To enhance delivery, a targeted nanoplatform (MDSPL) is developed.

Dynamic Fibrous Hydrogels for Stem Cell Homing and In Situ Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A dynamic fibrous hydrogel (DFH) is developed by covalent crosslinking of gelatin with tea‐derived trichomes, which integrates the structural and compositional fidelity of native extracellular matrix with photothermal and oxidative responsiveness, introducing a novel “stem cell recruits stem cell” strategy that orchestrates co‐homing of endogenous and ...

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

open access: yesAdvanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

Dysregulation of CircZNF79(5) Modulates YBX1 Stability and Selective Autophagy to Drive Hepatocellular Carcinoma Progression

open access: yesAdvanced Science, EarlyView.
In HCC, circZNF79(5) binds to YBX1 and functions as an oncogene, recruits BRCC36 to remove K63‐linked ubiquitin chains to stabilize YBX1 protein, and promotes HCC progression via the HIF‐1 signaling pathway. Conversely, circZNF79(5) silencing activates the AMPK/mTOR pathway, inducing p62‐mediated selective autophagic degradation of YBX1.
