- Realgar (AsS) has shown antitumor activity, but its pharmaceutical application is limited by poor aqueous solubility, low bioavailability, and systemic toxicity. In this study, we developed AS1411-functionalized albumin nanoparticles (AsS@ BSA-AS1411 NPs) for targeted delivery of realgar to triple-negative breast cancer (TNBC). Bulk AsS was converted into nanosized clusters and encapsulated in a bovine serum albumin (BSA) matrix, followed by surface conjugation with the nucleolin-targeting aptamer AS1411. The resulting nanoparticles showed suitable physicochemical properties and good colloidal stability in physiologically relevant media, together with enhanced cellular internalization in 4T1 cells. Compared with non-targeted nanoparticles, AS1411 modification significantly increased cytotoxicity and reduced the migratory ability of 4T1 cells. Mechanistic studies showed that treatment with AsS@BSA-AS1411 NPs was associated with upregulation of GADD45G and downregulation of mTOR, suggesting a stress-related antiproliferative effect. fluorescence imaging demonstrated increased tumor accumulation of AS1411-functionalized NPs. In 4T1 tumor-bearing mice, systemic administration of AsS@BSA-AS1411 NPs produced greater tumor growth inhibition than non-targeted controls, accompanied by increased apoptosis and reduced proliferative activity in tumor tissues. In addition, the formulation showed good tolerability, with no evident systemic toxicity or hemolytic activity. These findings indicate that AS1411-functionalized albumin NPs are a promising delivery system for improving the antitumor efficacy and safety profile of realgar in TNBC. - Source: PubMed

Dong LipingRan WenzhuoLi YanqiongYang LixiaZhou Xi - CXCL13 T cells and LAMP3 dendritic cells (DCs) are pivotal players in orchestrating anti-tumor immune responses, particularly within tumor tertiary lymphoid structures (TLS). However, their heterogeneity, differentiation trajectories, and clinical relevance in bladder cancer remain incompletely defined. This study integrated single-cell RNA sequencing (scRNA-seq) data (16 bladder cancer patients, 113,905 post-quality-control cells) and spatial transcriptomics to characterize CXCL13 T cell/LAMP3 DC subsets, their differentiation pathways (via Velocyto trajectory analysis), and intercellular crosstalk (via receptor-ligand mapping). A risk model (DTscore) was constructed using marker genes of these cells and validated in the IMvigor210 (atezolizumab-treated bladder cancer) and TCGA-BLCA cohorts. scRNA-seq clustering identified 10 immune and 3 nonimmune cell types, with T cells stratified into 8 subpopulations (including CD4CXCL13 T cells and CD8CXCL13 T cells) and DCs into 9 subgroups (including LAMP3 DCs). Receptor-ligand mapping and spatial transcriptomics confirmed functional crosstalk between CXCL13 T cells and LAMP3 DCs via key pairs (e.g., CCR7-CCL19, CXCR5-CXCL13, PDCD1-CD274) within TLS. The DTscore was developed using 8 marker genes (TSHZ2, ALOX5AP, GADD45G, TXN, CHN1, CCL19, CXCL13, ICA1) and exhibited robust prognostic and predictive performance: In the IMvigor210 cohort, high DTscore correlated with significantly poorer overall survival (OS) and a 3.27-fold lower immunotherapy response rate (11% vs. 36%, p = 4.23e-07); multivariate Cox regression confirmed DTscore as an independent OS predictor (hazard ratio = 1.97, p < 0.001). DTscore retained prognostic value in TCGA-BLCA (OS: p = 0.003; disease-specific survival: p < 0.001) and effectively predicted atezolizumab response even in the "immune desert" phenotype (p = 0.04). Combining DTscore with tumor mutational burden/tumor neoantigen burden yielded an AUC of 0.8122 for response prediction. Additionally, high DTscore was associated with higher OS hazard ratios in patients with wild-type TTN, RB1, EP300, or FGFR3 (all p < 0.01), while FGFR3 mutations correlated with lower immune checkpoint/CXCL13 expression. This study delineates the heterogeneity and interactions of CXCL13 T cell/LAMP3 DC subsets in bladder cancer TLS and validates DTscore as a robust tool for predicting OS and immunotherapy response, offering a potential guide for personalized bladder cancer treatment. - Source: PubMed

Zhou LinZhu JinchaoLiu YushanXu Bin - Based on findings from human atherosclerotic arteries and mouse arterial injury models, where ZHX2 expression is significantly downregulated, this study identifies ZHX2 as a critical inhibitor of pathological vascular remodeling. Functionally, local adenoviral overexpression of ZHX2 in vivo attenuates neointima formation in a mouse carotid artery ligation model, while in vitro experiments demonstrate that ZHX2 impedes the proliferation and migration of primary Vascular Smooth Muscle Cells (VSMCs). Mechanistically, integrated RNA-seq and ChIP-seq analyses reveal that ZHX2 transcriptionally regulates GADD45G, directly binding to its promoter and activating its transcription. The essential role of this pathway is confirmed by the finding that knockdown of GADD45G counteracts the inhibitory effects of ZHX2 overexpression on VSMC proliferation, migration, and neointima formation. Consequently, the ZHX2/GADD45G signaling axis is highlighted as a potential regulatory pathway in injury-associated neointimal remodeling. - Source: PubMed
Fan SiyuanWu XuelianGui LinWu YichenQiao BaoruLi YueZheng ZheHuang Kai - Intramuscular fat content is a key determinant of pork quality, influencing traits such as tenderness, juiciness, and flavor. However, the molecular mechanisms regulating intramuscular fat deposition in indigenous pig breeds remain incompletely understood. This study aimed to identify genes and regulatory mechanisms associated with intramuscular fat accumulation in Hezuo pigs. Longissimus dorsi muscle samples from Hezuo pigs with extreme high and low intramuscular fat contents were subjected to chromatin accessibility profiling and transcriptome sequencing. Comparative analyses identified 2201 differentially accessible chromatin regions and 588 differentially expressed genes between the two groups. Functional enrichment analyses indicated that these genes were mainly involved in lipid metabolism, focal adhesion, extracellular matrix-receptor interaction, fatty acid metabolism, and adenosine monophosphate-activated protein kinase signaling. Integration of chromatin accessibility and gene expression datasets identified 92 co-regulated genes associated with intramuscular fat deposition, including , , , , , , , , and . These findings reveal regulatory networks underlying intramuscular fat accumulation in Hezuo pigs and provide candidate genes and molecular resources for improving meat quality through genetic selection and breeding programs. - Source: PubMed
