Department of Nuclear Medicine and Minnan PET Center, Xiamen Key Laboratory of Development and Translation of Radiopharmaceuticals, the First Affiliated Hospital of Xiamen University, School of Medicine, Xiamen University, Xiamen 361102, Fujian, China.

Fibroblast activation protein (FAP) is a key molecule in the field of oncology, with significant impacts on tumor diagnosis and treatment. Importantly, it has paved the way for the development of radiotracers for quinoline-based FAP inhibitors (FAPIs), which are currently among the most promising radiotracers for PET imaging in cancer. We performed a bibliometric analysis of scientific publications related to FAP and FAPI-based radiotracers, which included the quantification and visualization of current research trends and prospects based on various bibliometric indicators.

Department of Oncology, Guang'anmen Hospital, China Academy of Chinese Medical Sciences, Beijing, China.

Programmed cell death-1 (PD-1) inhibitors and programmed cell death ligand 1 (PD-L1) inhibitors are considered effective alternatives for the primary treatment of recurrent metastatic cancers. However, they can induce various adverse events affecting multiple organ systems, potentially diminishing patients' quality of life, and even leading to treatment interruptions. Adverse events related to PD-1/PD-L1 inhibitors differ from those associated with CTLA-4 inhibitors and are more commonly observed in the treatment of solid tumors.

Vascular regeneration plays a vital role in tissue repair yet is drastically impaired in those with a spinal cord injury (SCI). Pericytes are of great significance as they are entwined with vessel-specific endothelial cells and actively contribute to maintaining the spinal cord's vascular network. Within the neurovascular unit (NVU), subtypes of pericytes characterized by various markers such as PDGFR-β, Desmin, CD146, and NG-2 are involved in vascular regeneration in SCI repair.

A chiral porous organic polymer (cPOP) was synthesized through nucleophilic substitution polymerization between dichloromaleimide and aromatic amine. This cPOP was used as a new chiral stationary phase (CSP) for gas chromatography (GC) chiral separation. In this work, we first used this cPOP as the CSP for gas chromatography to investigate its ability to separate racemic mixtures, including amino acid derivatives, chiral alcohols, aldehydes, alkanes, ketones, esters, and organic acids.

Glycosite-specific antibody-drug conjugates (gsADCs), which carry cytotoxic payloads at the conserved -glycosylation site, N297, of an IgG, have emerged as a promising ADC format with better therapeutic index. Conjugating the payloads aldehyde-based chemistry is more friendly to IgGs, and has been widely investigated. However, the efficiency of introducing an aldehyde tag at the N297 site is poor due to the complicated procedures required, such as the multiple-enzyme-catalyzed IgG glycoengineering process and the successive oxidation step, which always results in heterogeneous products and poor stability.

Bottlebrush polymers (BBPs) have garnered significant attention as advanced drug delivery systems, capable of transporting a diverse range of therapeutic agents, including both chemical drugs and biologics. Despite their effectiveness, the empty BBP vectors post-drug release may pose long-term safety risks due to their difficult systemic clearance. Here, a responsive degradable BBP platform for cancer therapy is developed, featuring a poly(disulfide) backbone grafted with fluorine-terminated zwitterionic side chains.

Immunometabolism is critical in the regulation of immunity and inflammation; however, the mechanism of preventing aberrant activation-induced immunopathology remains largely unclear. Here, we report that glyoxalase II (GLO2) in the glycolysis branching pathway is specifically downregulated by NF-κB signaling during innate immune activation via tristetraprolin (TTP)-mediated mRNA decay. As a result, its substrate S-D-lactoylglutathione (SLG) accumulates in the cytosol and directly induces D-lactyllysine modification of proteins.

Calcium/calmodulin-dependent protein kinase II α and β differentially regulate mammalian sleep.

Commun Biol

January 2025

Chinese Institute of Brain Research, Beijing (CIBR), and Chinese Institutes for Medical Research, Beijing (CIMR), Capital Medical University, Beijing, China.

While sleep is important, our understanding of its molecular mechanisms is limited. Over the last two decades, protein kinases including Ca/calmodulin-dependent protein kinase II (CaMKII) α and β have been implicated in sleep regulation. Of all the known mouse genetic mutants, the biggest changes in sleep is reported to be observed in adult mice with sgRNAs for Camk2b injected into their embryos: sleep is reduced by approximately 120 min (mins) over 24 h (hrs).
