Abstract In this study, tannins were investigated as sustainable flame retardants. The thermal and structural properties of tannic acid, chestnut, oak, and quebracho extracts were first characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), and Pyrolysis Combustion Flow Calorimetry (PCFC). Quebracho exhibited the most promising thermal performance, showing the lowest heat release and the highest char yield (≈38 wt.%). To further improve their efficiency, quebracho tannins were phosphorylated using phytic acid (QPHYA) or phosphoric acid (QPHOA). Phosphorus contents reached 13% and 15%, respectively, as confirmed by ICP and SEM–EDX analyses, while FTIR and NMR… More > Graphic Abstract

Abstract Objectives: Drug resistance is the major determinant of chemotherapy failure, leading to relapse and tumor progression, demonstrating the urgent need for novel antineoplastic drugs. This study aimed to evaluate the anticancer potential of two novel pyrazole derivatives, P3C.1 and P3C.2, and to elucidate their mechanism of action in cancer cells. Methods: The cytotoxicity of the compounds was evaluated across 27 different cancer cell lines via a nuclear staining assay. Subsequent flow cytometric and biochemical analyses were performed to assess reactive oxygen species (ROS) generation, apoptosis induction, mitochondrial integrity, and cell cycle progression. Additional studies included… More >

Abstract Objectives: Gastric cancer (GC) is often associated with high invasiveness, epithelial-mesenchymal transition (EMT), and resistance to 5-fluorouracil (5-FU), highlighting the need for novel therapeutic targets. This study explored whether diallyl disulfide (DADS) upregulates retinoic acid-related orphan receptor alpha (ROR) to weaken the protein kinase C alpha (PKC)/RORα-mediated RORα/β-catenin pathway, thereby inhibiting GC cell invasion, epithelial-mesenchymal transition (EMT), and enhancing 5-FU sensitivity. Methods: Human GC cell lines MGC-803 and SGC7901 were treated with DADS, RORα agonist SR1078/antagonist T0901317, and PKCα agonist TPA/antagonist GO6976. Cell proliferation (MTT), migration (scratch assay), invasion (Transwell), protein expression (Western blot), protein… More >

Abstract Background: After ischemic stroke, neutrophils hyperactivate, increasing in number and worsening inflammation, causing neural damage. Prior scRNA-seq showed Lrg1 modulates cells subsentence to cerebral ischemia-reperfusion injury, but its mechanism in regulating neutrophil accumulation/differentiation post-injury is unclear. Methods: Lrg1 knockout impact on neutrophil accumulation was assessed via immunofluorescence and western blot. Three-dimensional reconstruction of immunofluorescent staining analyzed cell-cell interactions among neutrophils and microglia. scRNA-seq of WT and Lrg1^-/- mice from GSE245386 and GSE279462 was conducted. Each group conducted oxidative phosphorylation scoring via Gene Set Enrichment Analysis (GSEA), while Metascape was employed to perform GO and KEGG enrichment… More > Graphic Abstract

Abstract Objectives: Weaning induces oxidative stress in pigs, increasing the risk of diarrhea and death. Intestinal damage is associated with obstructed intestinal cell cycles. To stop damage caused by reactive oxygen species (ROS), N-acetyl cysteine (NAC) has been widely employed. In this study, we examined changes in the intestinal cyclin of weaning piglets and assessed the impact of NAC on intestinal cell cycle arrest and intracellular signaling pathways. Methods: We conducted two animal experiments. In the first, we divided 12 litters of 120 newborn piglets into two groups: a control group and a weaning group. The… More >

Abstract Background: Picropodophllotoxin (PPT), a principal component of Podophyllum hexandrum root, demonstrates various beneficial biological activities in multiple cancer types, including antitumor and antiproliferative properties. Despite its known effects, the specific mechanisms by which PPT induces apoptosis in oral squamous cell carcinoma (OSCC) cells lack full clarification. Aims: This study aimed to evaluate the role of PPT in inducing apoptosis in OSCC cells by targeting signal transducer and activator of transcription 3 (STAT3) and to investigate the underlying molecular pathways. Methods: Human OSCC cell lines (HN22 and HSC4) were treated with PPT. Cell viability, colony formation, and apoptotic… More >

Abstract Background: Transmembrane emp24 trafficking protein 3 (TMED3) is associated with the development of several tumors; however, whether TMED3 regulates the progression of prostate cancer remains unclear. Materials and Methods: Short hairpin RNA was performed to repress TMED3 in prostate cancer cells (DU145 cells) and in a prostate cancer mice model to determine its function in prostate cancer in vitro and in vivo. Results: In the present study, we found that TMED3 was highly expressed in prostate cancer cells. In vitro, shTMED3 treatment suppressed the proliferation, invasion, and migration and promoted the apoptosis of DU145 cells. Additionally, the Kyoto Encyclopedia… More >

Abstract Background: Nasopharyngeal carcinoma (NPC) exhibits a significant prevalence in the southern regions of China, and paclitaxel (PTX) is frequently employed as a medication for managing advanced NPC. However, drug resistance is typically accompanied by a poor prognosis. Exploring the synergistic potential of combining multiple chemotherapeutic agents may represent a promising avenue for optimizing treatment efficacy. Methods: This study investigated whether 3-Methyladenine (3-MA) could potentiated the effect of PTX and its potential molecular mechanism. Samples were divided into the following categories: Negative control (NC) with the solvent dimethyl sulfoxide (DMSO, 0.5% v/v), PTX (400 nM), 3-MA… More >

Abstract The cancer cell metastasis is a major death reason for patients with non-small cell lung cancer (NSCLC). Although researchers have disclosed that interleukin 17 (IL-17) can increase matrix metalloproteinases (MMPs) induction causing NSCLC cell metastasis, the underlying mechanism remains unclear. In the study, we found that IL-17 receptor A (IL-17RA), p300, p-STAT3, Ack-STAT3, and MMP19 were up-regulated both in NSCLC tissues and NSCLC cells stimulated with IL-17. p300, STAT3 and MMP19 overexpression or knockdown could raise or reduce IL-17-induced p-STAT3, Ack-STAT3 and MMP19 level as well as the cell migration and invasion. Mechanism investigation revealed… More > Graphic Abstract

Abstract Fucoidan, a sulfate polysaccharide obtained from brown seaweed, has various bioactive properties, including anti-inflammatory, anti-cancer, anti-viral, anti-oxidant, anti-coagulant, anti-thrombotic, anti-angiogenic, and anti-Helicobacter pylori properties. However, the effects of low-molecular-weight fucoidan (LMW-F) on melanoma cell lines and three dimensional (3D) cell culture models are not well understood. This study aimed to investigate the effects of LMW-F on A375 human melanoma cells and cryopreserved biospecimens derived from patients with advanced melanoma. Ultrasonic wave was used to fragment fucoidan derived from Fucus vesiculosus into smaller LMW-F. MTT and live/dead assays showed that LMW-F inhibited cell proliferation in both A375 cells More >
