Protein S-palmitoylation, a dynamic and reversible post-translational modification involving the attachment of palmitate to cysteine residues, is a key regulator of protein functionality and cellular signalling. Dysregulation of this modification has emerged as a critical driver of cancer progression. Among the 23 DHHC palmitoyl transferases responsible for catalysing S-palmitoylation, aberrant expression of specific members is linked to tumorigenesis and development, underscoring their potential as promising therapeutic targets.

With growing public concern about the health effects of low-dose radiation, numerous studies have demonstrated that low-dose radiation can cause damage to the immune system, making intervention measures essential. This study investigated the protective effects of silybin against low-dose radiation-induced immune system damage and its underlying mechanisms at both the cellular and animal levels. At the cellular level, CCK-8 assays, ROS measurements, and RT-qPCR analysis revealed that silybin alleviated the reduction in RAW264.

Vascular endothelial growth factor B (VEGFB), a member of VEGF family, shares the VEGFR1 receptor with VEGFA. VEGFB has two isoforms, VEGFB and VEGFB, whose distinct biological roles remain poorly characterized. To elucidate the isoform-specific functions of VEGFB in tumorigenesis, we utilized transgenic mouse models, including VEGFB overexpression (aP2-Vegfb, aP2-Vegfb) and VEGFB knockout (Vegfb), along with tumor cell lines (B16-F10, U14 and LLC).

Depression and breast cancer (BC) demonstrate significant clinical comorbidity, yet their shared molecular mechanisms remain unclear, particularly regarding immune pathway regulation. This study systematically analyzed Depression-associated gene expression profiles (Gene Expression Omnibus (GEO) database) and BC transcriptomic data (The Cancer Genome Atlas (TCGA) database), identifying overlapping differentially expressed genes (DEGs). Functional enrichment (Gene Ontology (GO)/Kyoto Encyclopedia of Genes and Genomes (KEGG)) and protein-protein interaction (PPI) network analyses (STRING/Cytoscape) were employed to elucidate biological processes, followed by least absolute shrinkage and selection operator (LASSO) regression and receiver operating characteristic (ROC) curve validation to prioritize key genes.

Conventional pesticides are easily lost, and poorly targeted deposition causes pollution and economic losses because of their large particle sizes. Cellulase/pH Responsiveness Hollow Mesoporous Silica Nanoparticles (Hex/HMSN-CMC) was developed to respond rapidly to changes in the environment. The particle size of Hex/HMSN-CMC was 133.

Maximum power point tracking (MPPT) is a pivotal technology for photovoltaic (PV) systems. Due to variations in light intensity and temperature, the output characteristic curve of the photovoltaic system exhibits multi-peak phenomena, and traditional MPPT algorithms perform poorly in complex and changing environments. Therefore, this paper proposes an MPPT method grounded on an improved RIME optimization algorithm (IRIME).

Basket trial, as an innovative clinical trial design concept, marks the transformation of medical research from the traditional large-scale and single-disease treatment to the precise and individualized treatment. By gradually incorporating the Bayesian method during development, the trial design becomes more scientific and reasonable and increases its efficiency. The fundamental principle of the Bayesian method is the utilization of prior knowledge in conjunction with new observational data to dynamically update the posterior probability.

Immunotherapy is a potential strategy to suppress the postoperative recurrence and metastasis of triple-negative breast cancer (TNBC). However, the excessive accumulation of kynurenine (Kyn) leads to immunosuppressive tumor microenvironment (TME) and impedes immunotherapeutic efficacy. Herein, a two-pronged approach through "Kynurenine Starvation Therapy" is proposed based on the in-situ hydrogel implantation for postsurgical treatment of TNBC.

Research on functional recovery after ischemic stroke has primarily focused on non-invasive brain stimulation and motor rehabilitation therapies, while direct pharmacological interventions are relatively underexplored. This study utilized a bidirectional Mendelian randomization approach to investigate the causal relationship between 191 resting-state functional magnetic resonance imaging (rs-fMRI) features and post-ischemic stroke functional recovery (PISFR). Significant rs-fMRI phenotypes were identified, and Mendelian randomization was employed to determine their associated proteins.

DNA methylation is a common endogenous chemical modification in eukaryotic DNA, primarily involving the covalent attachment of a methyl group to the fifth carbon of cytosine residues, leading to the formation of 5-methylcytosine (5mC). This epigenetic modification plays a crucial role in gene expression regulation and genomic stability maintenance in eukaryotic systems. Ionizing radiation (IR) has been shown to induce changes in global DNA methylation patterns, which exhibit significant temporal stability.

Almost all patients of Neurofibromatosis Type I (NF1) develop benign peripheral nerve tumors called neurofibromas, which are derived from neural crest Schwann cell lineage progenitors with biallelic NF1 gene mutations. More than 90% of NF1 patients develop dermal neurofibromas (DN), and 25-50% develop plexiform neurofibromas (PN). In 8-13% of individuals with NF1, PN can transform into malignant peripheral nerve sheath tumors (MPNSTs), a type of nerve soft tissue sarcoma that is the main cause of mortality of NF1 patients.

Karmitoxin, produced by Karlodinium armiger, is structurally related to karlotoxin and amphidinols, two potent ichthyotoxic hemolysins with high affinity for sterols. Given these structural similarities, karmitoxin is believed to exhibit comparable toxic effects. Cytotoxicity was assessed in the fish gill cell line RTgill-W1 and the human epithelial colon cell line HCEC-1CT.
