A Dual-Functional Sulfur-Rich Copolymers for Stable Anchoring and Enhanced Conversion of Polysulfide in Lithium-Sulfur Batteries.

Sulfur-rich copolymers have gained a great deal of attention as promising cathode materials in Li-S batteries due to their low cost and naturally uniform sulfur dispersion. However, the poor electrical conductivity and shuttle effect cause rapid capacity decay and low sulfur utilization especially under high sulfur loading and low electrolyte/sulfur ratio. Herein, the FeS/C dispersed and Se-containing sulfur-rich copolymer (FSP) was synthesized by one-pot reaction of ferrocene, trithiocyanuric acid with SeS.

Association of hepatitis B core antibody level and hepatitis B surface antigen clearance in HBeAg-negative patients with chronic hepatitis B.

Predicting hepatitis B surface antigen (HBsAg) clearance is important for chronic hepatitis B (CHB) patients receiving pegylated interferon-alfa (Peg-IFN) therapy. We aimed to determine the predictive value of serum hepatitis B core antibody (anti-HBc) for HBsAg clearance. A total of 189 HBeAg-negative CHB patients who received Peg-IFN based therapy were retrospectively included and classified into two groups: nucleos(t)ide analogues (NAs) add-on Peg-IFN group (add-on group,  = 94) and Peg-IFN combined with NAs or Peg-IFN monotherapy group (combination or monotherapy group,  = 95).

Inhibiting S-palmitoylation arrests metastasis by relocating Rap2b from plasma membrane in colorectal cancer.

Rap2b, a proto-oncogene upregulated in colorectal cancer (CRC), undergoes protein S-palmitoylation at specific C-terminus sites (C176/C177). These palmitoylation sites are crucial for Rap2b localization on the plasma membrane (PM), as mutation of C176 or C177 results in cytosolic relocation of Rap2b. Our study demonstrates that Rap2b influences cell migration and invasion in CRC cells, independent of proliferation, and this activity relies on its palmitoylation.

Heat Shock Protein 90 Interactome-Mediated Proteolysis Targeting Chimera (HIM-PROTAC) Degrading Glutathione Peroxidase 4 to Trigger Ferroptosis.

Targeted protein degradation (TPD) is an emerging therapeutic paradigm aimed at eliminating the disease-causing protein with aberrant expression. Herein, we report a new approach to inducing intracellular glutathione peroxidase 4 (GPX4) protein degradation to trigger ferroptosis by bridging the target protein to heat shock protein 90 (HSP90), termed HSP90 interactome-mediated proteolysis targeting chimera (HIM-PROTAC). Different series of HIM-PROTACs were synthesized and evaluated, and two of them, GDCNF-2/GDCNF-11 potently induced ferroptosis via HSP90-mediated ubiquitin-proteasomal degradation of GPX4 in HT-1080 cells with DC values of 0.

Cathepsin B Nuclear Flux in a DNA-Guided "Antinuclear Missile" Cancer Therapy.

Some antinuclear antibodies (ANAs) bind extracellular nucleic acids released into tumor environments and are pulled into the nuclei of live cancer cells through nucleoside salvage pathways, independent of tumor-specific surface antigens. Here we show that ANA nuclear penetration induces nuclear flux by the lysosomal protease cathepsin B and leverage this mechanism to design an antinuclear antibody-drug conjugate (ANADC) with cathepsin B-labile drug linker. The ANADC targets nucleic acid exhaust from necrotic tumors and crosses membrane barriers through nucleoside salvage as a DNA-seeking and tumor agnostic "antinuclear missile" cancer therapy.

Corticothalamic input derived from corticospinal neurons contributes to chronic neuropathic pain after spinal cord injury.

Neuropathic pain is a significant and persistent issue for individuals with spinal cord injuries (SCI), severely impacting their quality of life. While changes at the peripheral and spinal levels are known to contribute to SCI-related pain, whether and how supraspinal centers contribute to post SCI chronic neuropathic pain is poorly understood. Here, we first validated delayed development of chronic neuropathic pain in mice with moderate contusion SCI.

Regulation of neuronal plasticity associated with neuropsychiatric disorders by the orexinergic system.

Orexins are a family of neuropeptides secreted by neurons in the lateral hypothalamus (LH). These peptides act widespreadly across the body by interacting with specific orexin receptors on target cells, which comprise the orexinergic system. Emerging evidence has revealed that the orexinergic system is tightly associated with neuropsychiatric disorders; however, the underlying mechanisms require further exploration.
