research on the study of houses, condominiums and buildings in Taiwan’s metropolitan areas continues to be an important area of research. In real estate forecasting and analysis, methods such as statistical analysis and questionnaire data collection are widely used. However, when multidimensional data is considered, these methods are time-consuming and inadequate. This study aimed to build a real estate forecasting model that can adapt to a changing environment. data were collected from public government databases, the collected data were standardized for accurate clustering, an appropriate data clustering algorithm was applied to the standardized data, and cross-statistical analysis was performed to verify the adopted algorithm. We used a deep learning based on autoencoder algorithm to increase the accuracy of the clustering analysis. A double-bottom map particle swarm optimization (dBM-PSO) clustering algorithm was then used to determine the optimal clustering solution. Cluster analysis and deep learning were conducted on data collected from public websites to understand the factors that led to the sustained increase in housing prices in Taiwan over the past decade. The results of this study indicate that three key factors—the number of real estate transactions, the average unit price of real estate transactions, and the building material and construction index—significantly affected real estate prices in Taiwan. Our results could help researchers and governments to focus on specific aspects of real estate development without being influenced by other related factors. In addition, the relationships between real estate trends and the aforementioned three key factors were determined to obtain valuable information that can enable the Taiwanese government to regulate the property market and prevent excessive growth. The framework proposed in this paper allows researchers and governments to focus on specific aspects of real estate development without being influenced b

Traumatic brain injury (TBI) constitutes a significant burden on global healthcare systems, especially affecting younger populations, where it is a leading cause of disability and mortality. Current treatments for TBI mainly focus on preventing further brain damage and controlling symptoms. However, despite these approaches, several clinical needs remain unmet. Revelations from single-cell RNA sequencing (scRNA-seq) performed to determine cell-type heterogeneity and gene expression changes in brain tissue indicated that brain trauma increases the expression of lysine-specific demethylase 1 (LSd1) and secretase 2 (BACE2). To capitalize on this finding, a medicinal chemistry campaign was conducted to pragmatically insert tranylcypromine, an LSd1 inhibitor, into a carefully designed BACE2 inhibitory template (BACE2-IN-1). Additionally, tranylcypromine was structurally modified to enhance the effects of LSd1 inhibition in TBI. As a result, a tractable neuroprotective agent, BACE2-IN-1/tranylcypromine-based compound 4, was identified, showing potential to maintain Neuro-2a cell survival by alleviating mitochondrial damage after oxidative stress. Compound 4 also restored TBI-mediated inhibition of the cholesterol biosynthetic pathway (mevalonate pathway) and damage of redox metabolism, increasing neuroprotective effects. Furthermore, behavioral assays, including nest-building and cognitive performance tests, demonstrated significant improvement in mice post-TBI following treatment with compound 4. Taken together, the outcomes of this study validate the favorable effects of inhibiting LSd1 and beta-secretase in mitigating mitochondrial stress and promoting neurometabolic recovery in TBI. These findings pave the way for the development of rationally designed inhibitors as promising neuroprotective agents, potentially addressing unmet clinical needs in TBI treatment. © 2025 The Authors

BACKGROUNd:Mangosteen (Garcinia mangostana L.) pericarp extract has demonstrated potential against Alzheimer's disease (Ad) and diabetes mellitus (dM). This study introduces a rapid dereplication and comparative approach to identify and characterize acetylcholinesterase (AChE) and α-glucosidase inhibitors in mangosteen pericarp. Using protein-subtraction, MS profiling, and computational modeling is effective for screening, identifying, and analyzing enzyme-inhibiting compounds from plant sources, and quantitative analysis of the main components has been performed. RESULTS:The Mangosteen pericarp extract observed significant inhibitory activity against α-glucosidase and AChE, with IC50 values of 31.02 and 70.56 µg/mL, respectively. By comparing profiles of protein-subtracted extracts with non-treated extracts, eight potential inhibitors for each enzyme were identified: 8-desoxygartanin, gartanin, 3-isomangostin, β-mangostin, 9-hydroxycalabaxanthone, γ-mangostin, α-mangostin, and garcinone E. The α-mangostin was the most abundant, comprising 39.589% of the extract. Molecular docking revealed these inhibitors target the peripheral anionic site of AChE and the active site of α-glucosidase, forming key hydrogen bonds and pi-pi stacking interactions. CONCLUSION:This study emphasizes mangosteen pericarp as a promising natural source of these inhibitors, with potential for use in developing nutraceuticals and pharmaceuticals. The study validated a systems biology approach by applying dereplication and comparative UPLC-ESI-MS/MS metabolomics profiling to identify target-binding molecules in both protein-treated and untreated plant extracts. Further confirmation was obtained through molecular docking predictions, mechanism analysis, and compound quantification assays.

The immunogenicity of polyethylene glycol (PEG) remains a critical challenge in nanomedicine, as pre-existing anti-PEG antibodies can compromise therapeutic efficacy through accelerated blood clearance (ABC) and life-threatening hypersensitivity. Here, we address this challenge by engineering the PEG architecture, creating short-chain dense brush PEGylation (PEG500) on rigid mesoporous silica nanoparticles (MSNs). Unlike conventional PEG2000-liposomes, MSN-PEG500 evades antibodies via three synergistic mechanisms: (1) short-chain PEG500 reduces epitope accessibility, (2) high grafting density (4.43 chains/nm2, according to TGA) forms an dense steric shield, and (3) the rigid silica surface prevents PEG burial. ELISA studies demonstrated that, at equivalent nanoparticle concentrations, MSN-PEG500 exhibits a 26-fold reduction in anti-PEG IgG (6.3) binding and a 1000-fold reduction in anti-PEG IgM (AGP3) binding compared to Lipodox (PEG2000), both of which target the PEG backbone. Furthermore, radiolabeled MSN-PEG500 achieved prolonged circulation and 25% tumor accumulation (Id/g) at 24 hours. In strongly immunized mice, doxorubicin-loaded MSN-PEG500 preserved therapeutic efficacy and 100% survival, whereas Lipodox induced fatal hypersensitivity. Mechanistic investigations revealed that complement activation drives PEG2000 immunotoxicity, and pretreatment with the C3 inhibitor compstatin effectively mitigated temperature drops from 10°C to 2°C in immunized hosts. By demonstrating that nanoscale control of polymer conformation dictates immunological fate, this work provides a clinically translatable blueprint for developing immune-evasive nanomedicines. © 2025, The Authors.

Cyclin-dependent kinase 8 (CdK8) plays a crucial role in the transforming growth factor beta (TGF-β) signaling pathway, which is critical to the pathology of idiopathic pulmonary fibrosis (IPF). CdK8 promotes the epithelial-mesenchymal transition (EMT) and excessive extracellular matrix (ECM) deposition, making it a promising target for IPF treatment. This study focused on optimizing F059–1017, a previously identified CdK8 inhibitor, to enhance its potency. Through integrated structure-based modifications, a series of compounds was synthesized, and their inhibitory effects on CdK8 were tested. Results indicated that substituting with cyclopentanone significantly improved the inhibitory activity, and compound 4j demonstrated the best potency (IC₅₀ = 16 nM). Notably, compared to F059–1017, its potency increased 35-fold, and kinase profiling revealed that the compound was selective for CdK8. Compound 4j inhibited the TGF-β1-induced EMT, cell migration, and morphological changes in A549 cells at a concentration of 0.1 μM and inhibited ECM and EMT protein expressions. In addition, the compound blocked TGF-β1-induced transcriptional changes and inhibited Smad3 and RNA polymerase II phosphorylation. These results highlight the potential of the optimized CdK8 inhibitor as a prospective drug for IPF treatment. © 2025 The Authors

Renal cell carcinoma (RCC) is a well-known malignancy characterized by specific gene mutations that elevate its occurrence. It can be categorized into clear cell RCC (ccRCC), papillary RCC, and chromophobe RCC, which account for approximately 85 % of all primary RCC cases. The mutations typically involve single-nucleotide variants (SNVs) that lead to amino acid substitutions, which influence various biological functions, including gene expression. Therefore, predicting the functional consequences of RCC-related single-nucleotide polymorphisms (SNPs), including substitutions, insertions, deletions, and duplications, is crucial for the effective clinical management of RCC. In recent years, the accessibility and popularity of tools for predicting SNP functional variations have grown, especially in research concerning the potential risks associated with key gene mutations in cancer. Accordingly, this study focused on commonly mutated genes in ccRCC, namely VHL, BAP1, PBRM1, and SETd2. Public data from sources such as The Cancer Genome Atlas and the National Center for biotechnology Information were used to identify 61 gene mutation positions. Nine nonsynonymous mutation prediction tools were used for analysis, namely SIFT, Polyphen-2, Mutation Assessor, Fathmm, MutPred, CHASM, Revel, Provean, and SNP&GO. The tools were evaluated by their statistical performance, prediction distribution, and receiver operating characteristic curves. The three tools with the highest accuracy for predicting the functional consequences of mutations in the four frequently mutated genes associated with ccRCC were SIFT (accuracy of 0.75), Provean (0.7), and Polyphen-2 (0.69). These findings offer valuable insights into predicting ccRCC-related gene mutation effects, but further research and validation are essential to support their clinical applications. © 2025

ST6GAL1 plays a crucial role in the progression of triple-negative breast cancer (TNBC), highlighting its potential as a therapeutic target for this aggressive cancer subtype. due to the high metastatic potential of TNBC and the limitations of current therapies, selective and potent ST6GAL1 inhibitors are urgently needed. In this study, a scaffold-hopping approach from lithocholic acid to bishomolithocholic acid successfully led to the discovery of novel ST6GAL1 inhibitors, SPP-037 and HZF01, with enhanced biological activity and selectivity. Both compounds significantly inhibited MdA-MB-231 cell migration, HUVEC tube formation, tumor growth, and metastasis in vitro and in vivo. Molecular docking studies revealed key interactions between the ST inhibitors and ST6GAL1, supporting their enhanced selectivity and binding affinity. Additionally, SPP-037 and HZF01 were found to block integrin α2,6-sialylation, disrupting integrin activation and downstream signaling pathways involving the phosphorylation of focal adhesion kinase (FAK) and paxillin, which are critical for cell migration. These results underscore the potential of targeting ST6GAL1 to suppress tumor progression and metastasis, offering a promising avenue for treating aggressive breast cancer. © 2025 Elsevier Masson SAS

Immunotherapy has paramount importance in treating chronic immune diseases, and vaccine development. Hyaluronic acid (HA) has been shown to elicit molecular weight-related distinct immune responses. Nonetheless, the particle size-dependent immunomodulatory effects of hyaluronic acid nanoparticles (HA-NPs) remain blurred. Thus, the present study aimed at investigating the effect of polymer configuration and particle size of HA-NPs assembled from HA_36K-OdA and HA_360k-OdA analogs in modulating macrophage-related immune activities. In the in vitro experiments, HA-NPs of HA_36k-OdA analogs garnered significantly enhanced nitrite production with low interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) secretion in macrophages. Furthermore, smaller (< 200 nm) HA_36k-OdA NPs activated Cd11b⁺ cells whereas a ∼ 130 nm HA_36k-OdA15 NPs preferentially induced Cd11c⁺ cells in vivo, indicating the influence of particle size on the antigen-presenting cells (APCs) recruitment. Interestingly, self-assembled HA_36k-OdA15 NPs without ovalbumin (OVA) activated immature dendritic cells (dCs) and augmented their migration toward the lymph nodes (LNs). Notably, HA_36k-OdA15-activated macrophages behaved like M1 phenotype macrophages. Overall, our findings garnered valuable insights about the design and application of HA-NPs for modulating the immune responses in nanoscale materials-based immunotherapy. © 2025

Aims: Successful implantation relies on high-quality blastocysts, uterine receptivity, and effective embryo-endometrium communication. This study investigated the effects of umbilical cord-derived mesenchymal stem cells (UC-MSC) secretomes on embryo development and implantation. Main methods: Trophoblastic spheroids and murine embryos were used to evaluate the impact of UC-MSC secretomes. Embryos obtained through superovulation were cultured in vitro and divided into five groups: a control group and four experimental groups treated with varying concentrations of UC-MSC secretomes (2.5, 5, 10, and 50 μg/mL). Embryo development competence and implantation potential were assessed in each group, and the expression levels of related genes were analyzed. Key findings: Supplementation with UC-MSC secretomes significantly enhanced trophoblast cell migration. It also stimulated endometrial cell proliferation and upregulated key implantation-related genes (LIF, LIFR, VEGFA, ITGB3, and ITGAV), improving endometrial receptivity and adhesion in trophoblastic spheroid co-cultures. While morulation rates of murine embryos remained unchanged, UC-MSC secretomes supplement significantly increased blastulation, pluripotency gene expression, and hatching rates. Supplementation with 10 and 50 μg/mL significantly increased blastocyst diameter and blastomere number, as well as embryo adhesion, outgrowth areas, and implantation rates. Additionally, growth factor analysis showed elevated VEGF-A and PdGF-AA levels in the culture media. Significance: This study demonstrates that UC-MSC secretomes enhance both embryo development and endometrial cell function, facilitating implantation potential. These findings suggest their potential utility in supporting preimplantation embryos and improving maternal endometrial receptivity in ART. © 2025 The Authors
