Unlabelled: The accurate identification of catalytic residues contributes to our understanding of enzyme functions in biological processes and pathways. The increasing number of protein sequences necessitates computational tools for the automated prediction of catalytic residues in enzymes. Here, we introduce SCREEN, a graph neural network for the high-throughput prediction of catalytic residues via the integration of enzyme functional and structural information.

Tracing Sentinel Lymph Nodes and Inhibiting Lymphatic Metastasis with TiN Nanobipyramids Through Photothermal Therapy.

Background: The lymphatic system is the major route of cancer metastasis, and sentinel lymph nodes (SLNs) are the first station for the spread of cancer cells. Accurate identification of SLNs by tracers during surgery is crucial for SLN biopsy and lymphadenectomy. However, conventional monomodal tracers such as blue dyes and carbon nanoparticles often induce a misjudgment of SLNs and thus are still unsatisfying for clinical applications.

Phenotypic screens identify SCAF1 as critical activator of RNAPII elongation and global transcription.

Transcripts produced by RNA polymerase II (RNAPII) are fundamental for cellular responses to environmental changes. It is therefore no surprise that there exist multiple avenues for the regulation of this process. To explore the regulation mediated by RNAPII-interacting proteins, we used a small interfering RNA (siRNA)-based screen to systematically evaluate their influence on RNA synthesis.

PGRN protects against serum deprivation-induced cell death by promoting the ROS scavenger system in cervical cancer.

Progranulin (PGRN), an autocrine growth factor with tumorigenic roles in a variety of tumors, is a putative survival factor for normal and cancer cells in vitro. However, the fundamental mechanism of PGRN-mediated survival of cancer cells suffering from various types of microenvironmental stresses, such as serum deprivation, remains unknown. We show here that serum deprivation decreases intracellular PGRN protein levels in cervical cancer cells.

Crystal structure of the human LAG-3-HLA-DR1-peptide complex.

T cell activity is governed by T cell receptor (TCR) signaling and constrained by immune checkpoint molecules, including programmed cell death protein 1 (PD-1), cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), and lymphocyte activation gene 3 (LAG-3). The basis for how LAG-3 binds to human leukocyte antigen class II molecules (HLA-II) remains unknown. Here, we present the 3.

Selection of streptococcal glucan-binding protein C specific DNA aptamers to inhibit biofilm formation.

Streptococcus mutans is a commensal oral bacterium, yet its capacity for extensive biofilm formation is a major contributor to dental caries. This study presents a novel biofilm inhibition strategy by targeting GbpC, a cornerstone protein in S. mutans biofilm architecture, with specific DNA aptamers.

Evaluation of the double-zone hemolysis (DZH) test for the detection of livestock-associated methicillin-resistant .

Unlabelled: Livestock-associated methicillin-resistant (LA-MRSA), such as clonal-complex (CC)398, are of clinical relevance due to their multi-drug resistance profiles, adding to the overall burden of MRSA in humans. The objective was to evaluate the double-zone hemolysis (DZH) test as a simple and reliable method for detecting LA-MRSA in the clinical microbiology laboratory. isolates assigned to CC398 ( = 183; 152 MRSA/31 methicillin-susceptible [MSSA]), CC1 ( = 44; MRSA), and other CCs ( = 144; 94 MRSA/50 MSSA) were investigated.

Melleatin, an antibiofilm multitasking protein with rRNA N-glycosylase and nuclease activity from Armillaria mellea fruiting bodies.

Several studies highlight the identification of some enzymes with additional abilities, especially those involved in metabolic pathways and/or host defence processes, classified as multitasking proteins. In this context, we report the characterization of melleatin (17.5-kDa), a multitasking enzyme isolated from Armillaria mellea fruiting bodies.

First-in-class transactivator-free, doxycycline-inducible IL-18-engineered CAR-T cells for relapsed/refractory B cell lymphomas.

Although chimeric antigen receptor (CAR) T cell therapy has revolutionized type B cancer treatment, efficacy remains limited in various lymphomas and solid tumors. Reinforcing conventional CAR-T cells to release cytokines can improve their efficacy but also increase safety concerns. Several strategies have been developed to regulate their secretion using minimal promoters that are controlled by chimeric proteins harboring transactivators.

European Respiratory Society Research Seminar on Preventing Pediatric Asthma.

This report is a summary of the presentations given at the European Respiratory Society's Research Seminar on Asthma Prevention. The seminar reviewed both epidemiological and mechanistic studies and concluded that; (i) reducing exposure of pregnant women and children to air pollution will reduce incident asthma, (ii) there are promising data that both fish oil and a component of raw cow's milk prevent asthma, and (iii) modulating trained immunity by either mimicking helminth infection or oral and sublingual bacterial products is a promising area of research.

PAF1-mediated transcriptional reprogramming confers docetaxel resistance in advanced prostate cancer.

Advanced prostate cancer (PCa) remains a significant clinical challenge, and docetaxel plays a significant role in disease management. Despite the efficacy of docetaxel as a first-line chemotherapy, resistance often develops. We developed three clinically relevant in vitro PCa cell models and transcriptomic analysis identified that the Paf1/RNA polymerase II complex component (PAF1)-associated pluripotent-transcription factor (TF), SOX2, plays a crucial role in docetaxel resistance.

Disruption of PCSK9 Suppresses Inflammation and Attenuates Abdominal Aortic Aneurysm Formation.

Background: Abdominal aortic aneurysm (AAA) is a chronic vascular inflammatory disease without effective medications. PCSK9 (proprotein convertase subtilisin/kexin 9), a serine protease from the proprotein convertase family, has recently been associated with AAA in human genome-wide association studies. However, its role in AAA is unknown.

Impact of vitamin D on hyperoxic acute lung injury in neonatal mice.

Background: Prolonged exposure to hyperoxia can lead to hyperoxic acute lung injury (HALI) in preterm neonates. Vitamin D (VitD) stimulates lung maturation and acts as an anti-inflammatory agent. Our objective was to determine if VitD provides a dose-dependent protective effect against HALI by reducing inflammatory cytokine expression and improving alveolarization and lung function in neonatal mice.
