Despite recent advances in cancer therapy, there has been little change in cure and survival rates in patients suffering from gastric cancer. The use of conventional chemotherapeutic agents such as docetaxel is limited by some disadvantages such as alopecia and hematotoxicity. This study focused on the antitumor effects of solid lipid nanoparticles loaded with docetaxel (SLN-DTX) on gastric adenocarcinoma cells. SLN-DTX showed cytotoxicity against cancer cells (AGS), demonstrating an IC50 value lower than the concentration of free DTX after 24 h of treatment, evidencing the efficiency of nanoparticles. Morphological analysis revealed structural alterations, including cell rounding and reduced cytoplasmic projections posttreatment. SLN-DTX and DTX induced damage to microtubules, binding proteins, and core fragmentation, impairing cell adhesion and proliferation. They also showed changes in analyses involving cellular organelles (mitochondria and lysosomes) and cellular metabolism. SLN-BLANK did not show significant toxicity in the AGS tumor lineage in any assays, behaving similarly to the untreated control. Association of docetaxel with solid lipid nanoparticles (SLN-DTX) demonstrates significant efficiency in inducing cytotoxic effects in gastric adenocarcinoma cells, since this formulation exhibited potent antitumor activity. Treatment with nanostructured docetaxel caused morphological and metabolic changes in addition to altering the release of molecules relevant to tumor progression. These findings support the potential use of SLN-DTX as a promising drug delivery system, offering an innovative and effective approach for gastric cancer treatment while potentially reducing the side effects associated with conventional therapies.</p>\u0000 </section>\u0000 </div>","PeriodicalId":15151,"journal":{"name":"Journal of Biochemical and Molecular Toxicology","volume":"39 9","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jbt.70456","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most important pathological characteristics of AD is the deposition of β-amyliod (Aβ) peptide, which initiates a spectrum of cerebral neuroinflammation. Vascular changes also play an important role in the pathophysiology of the disease. Cytokines, secreted by immune cells, can facilitate cell-to-cell signaling and influence the functions of the central nervous system (CNS). These important mediators of the immune system, which are known to orchestrate various molecular and cellular mechanisms in both physiological and pathological situations, can be upregulated or downregulated, leading to a complex crosstalk with numerous receptors mediating pro-inflammatory and/or anti-inflammatory actions. In particular, the interleukin (IL)-1 family of cytokines has been implicated to significantly correlate with AD pathogenesis among other cytokines in the CNS. The IL-1 family of cytokines is essential in both the innate and adaptive immune responses. This pleiotropic family of cytokines includes IL-1α, IL-1β, IL-1 receptor antagonist (RA), IL-18, IL-33, IL-36α, IL-36β, IL-36γ, IL-36RA, IL-37, and IL-38. Recent studies have demonstrated that the upregulation of pro-inflammatory cytokines, such as IL-1α and IL-1β, or the downregulation of anti-inflammatory mediators, exerts multifaceted influences on both neurodegeneration and neuroprotection. The lack of effective treatment for AD necessitates the search for new drugs that target several processes in the disease's pathology. This review aims to give a comprehensive overview of the emerging roles of the IL-1 family of cytokines in AD pathology and to explain their perspectives on introducing novel strategies for effective therapeutic/neuropsychiatric management of AD in clinical settings by discussing both the pathogenic and protective roles of these cytokines.</p></div>","PeriodicalId":15151,"journal":{"name":"Journal of Biochemical and Molecular Toxicology","volume":"39 9","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the end, the OVX mice were further divided into two groups: OVX-HFD and OVX-HFD-PPT (ERα agonist). The findings showed that ovariectomy led to weight gain and increased energy intake in HFD mice, which were accompanied by increased levels of orexigenic neuropeptide Y (NPY) and ER-stress and decreased levels of anorexigenic α-melanocyte-stimulating hormone (α-MSH) and leptin signaling in the hypothalamus. In contrast, treatment with PPT significantly attenuated these effects, leading to reduced body weight and energy intake. Mechanistically, PPT treatment decreased the level of NPY and increased α-MSH in the hypothalamus. Furthermore, PPT treatment reduced hypothalamic ER stress markers, such as GRP78 and ATF6, and enhanced leptin signaling by increasing the phosphorylation of JAK2 and STAT3.

In this study, we explore the impacts of Dynorphin A on mitochondrial function and biogenesis within human OS U2OS cells. Human osteosarcoma (U2OS) cells were treated with Dynorphin A at varying concentrations for 48 h. Cell viability and cytotoxicity were assessed using the Cell Counting Kit-8 (CCK-8) and LDH assay, respectively. Mitochondrial function was evaluated by measuring complex IV activity, oxygen consumption rate (OCR), and ATP production, while mitochondrial biogenesis was analyzed by determining the mtDNA/nDNA ratio, mitochondrial protein expression (NDUFB8 and MTCO<sub>2</sub>), and mitochondrial mass (MitoTracker Red staining). The expression of key mitochondrial regulators (PGC-1α, Nrf1, TFAM) and SP-1 was quantified using real-time RT-PCR and Western blot analysis. Our findings reveal that Dynorphin A notably decreases cell viability and enhances the release of lactate dehydrogenase (LDH)., indicating cytotoxicity. It also impaired mitochondrial function, as evidenced by a decrease in complex IV activity, oxygen consumption, and ATP production. Additionally, Dynorphin A suppressed mitochondrial biogenesis, shown by a reduced mtDNA/nDNA ratio, lower expression of mitochondrial proteins (NDUFB8 and MTCO2), and decreased mitochondrial mass. Furthermore, Dynorphin A downregulated key mitochondrial regulators, including PGC-1α, Nrf1, and TFAM. Notably, Dynorphin A also upregulated SP-1 expression, and silencing SP-1 reversed its effects on mitochondrial function and biogenesis.

While variations in susceptibility to liver injury between the C57BL/6(J) and (N) substrains are well recognized, substrain influence on the innate immune response and regenerative outcomes which influence development of acute liver failure are unknown. We compared these aspects temporally between 6J and 6N mice following a 300 mg/kg APAP overdose. Consistent with prior findings, 6N mice exhibited higher liver injury compared to 6J mice. Neutrophil and macrophage infiltration followed similar patterns, but with different temporal dynamics, with 6J mice showing a rapid but transient response, while 6N mice exhibited delayed and prolonged immune activity. Importantly, these immune dynamics were accompanied by delayed regeneration and sustained p21 expression, indicating impaired regeneration in 6N mice. Taken together, both substrains displayed broadly similar immune behavior in terms of cytokine expression and cell recruitment patterns, with the delayed immune resolution and regeneration observed in 6N mice being reflective of the extent of injury rather than intrinsic differences in immune function. Thus, our study emphasizes the need to evaluate multiple time points to fully capture the evolving nature of liver injury and recovery during APAP hepatotoxicity.
