Immunotherapy has emerged as a promising approach for TNBC, with tumor-infiltrating immune cells (TICs) in the tumor microenvironment (TME) serving as a critical cellular basis for its efficacy. However, the success of immunotherapy in TNBC is often limited due to the immunosuppressive nature of the TME and the heterogeneity of TNBC. Ferroptosis, a form of iron-dependent programmed cell death regulated by metabolic networks including iron, glutathione (GSH), and lipid metabolism, has shown potential to enhance anti-tumor immunity. Recent studies have demonstrated that ferroptosis can modulate immune responses by promoting the infiltration and activation of TICs, thereby improving the outcomes of immunotherapy. However, ferroptosis in immunosuppressive cells such as regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs) can trigger an \"immunosuppressive wave,\" affecting other immune cells in the tumor immune microenvironment. This demonstrates the dual role of ferroptosis in TNBC therapy, emphasizing the need for a nuanced understanding of its effects on different immune cells and tumor cells.

These aberrant glycosylation signatures not only offer insights into cancer biology but also serve as valuable diagnostic markers and potential therapeutic targets across a range of malignancies. This review explores the mechanisms underlying glycosylation alterations in cancer. We discuss the molecular basis of these changes, including genetic mutations, epigenetic regulation, and oncogene-driven shifts in glycosylation pathways. Additionally, we highlight recent advancements in glycomics research, with a focus on how these alterations influence tumor progression, angiogenesis, and the tumor microenvironment. Furthermore, the review considers the clinical implications of glycosylation changes, including their role in resistance to anti-cancer therapies and their potential as biomarkers for personalized treatment strategies.

While the ANXA1-FPR axis is implicated in the pathogenesis of IBD, its relationship with the NLRP3 inflammasome in this context has not been established. Thus, this study aimed to elucidate the intricate relationship between ANXA1, FPRs, and the NLRP3 inflammasome in the pathogenesis of IBD. For this purpose, mRNA and protein expression of ANXA1, FPRs, and NLRP3 inflammasome were analyzed using transcriptomic data (GSE179285) and immunohistochemistry on ileum and colon samples from CD patients and healthy controls. In vitro, ANXA1-derived peptide Ac_2-26's effect was tested on TNF-α-activated Caco-2 cells. Transcriptome analysis of GSE179285 revealed significantly increased levels of ANXA1, FPR1, FPR2, and NLRP3 transcripts in inflamed CD segments compared to controls. Immunohistochemistry confirmed these findings, showing strong immunoreactivity for ANXA1, FPR2, and NLRP3 in CD samples, particularly in the intestinal epithelium and inflammatory infiltrate. In vitro, ANXA1 and NLRP3 were co-expressed in Caco-2 cells stimulated with TNF-α. The peptide Ac_2-26 at 2 ng/mL significantly increased caspase-1 and IL-1β levels, enhancing NLRP3 inflammasome activation. Ac_2-26 also reduced ROS production and preserved epithelial integrity by enhancing occludin and cadherin expression. Overall, this study highlights the crucial role of ANXA1-FPR axis in regulating inflammation in CD and its potential therapeutic implications. Ac_2-26 modulates NLRP3 inflammasome activation and oxidative stress, preserves epithelial barrier integrity, and shows promise as a therapeutic target for IBD treatment.</p>","PeriodicalId":18724,"journal":{"name":"Molecular and Cellular Biochemistry","volume":" ","pages":"5141-5155"},"PeriodicalIF":3.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144111408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by epidermal barrier dysfunction and immune dysregulation. This study aimed to evaluate BJE anti-inflammatory and skin-protective effects, and its potential mechanisms in treating AD. The ability of BJE to restore the epidermal barrier was assessed in HaCaT cells. In LPS-induced RAW264.7 cells, the anti-inflammatory potential of BJE was evaluated by measuring NO, IL-6, PGE2, and TNF-α. Western blot analysis was used to assess the regulation of the MAPK pathway. An in vivo AD-like mouse model was established using MC903, and measurements of body weight, ear thickness, and AD symptoms were recorded. Histological analysis quantified mast cell infiltration, while western blot determined FLG, LOR, and ELOVL6 expression. ELISA was used to measure TNF-α, IgE, IL-4, and IL-13 levels. Flow cytometry assessed the effect of BJE on Th cell phenotypes. BJE significantly enhanced skin barrier protein expression (CERS2, LOR, HAS-1, HAS-2, FLG) in HaCaT cells. It significantly reduced the levels of NO, IL-6, PGE2, and TNF-α in LPS-treated RAW264.7, demonstrating its anti-inflammatory potential. Mechanistically, BJE inhibited MAPK activation. BJE decreased ear thickness, improved skin lesions, and relieved AD symptoms in AD-like mice. In addition, BJE effectively suppressed mast cell infiltration and hyperkeratosis. BJE also decreased levels of TNF-α, IgE, IL-4, and IL-13 while increasing LOR, ELOVL6, and FLG expressions. Furthermore, BJE modulated Th1, Th2, and Th17 cell proportions. BJE promoted epidermal barrier repair in HaCaT, suppressed the LPS-induced inflammation in RAW264.7, enhanced the skin barrier integrity in AD-like mice, and exhibited immunomodulatory effects by restoring Th cell balance. These findings highlighted the therapeutic potential of BJE in AD through its dual action of anti-inflammation and skin barrier restoration.</p>","PeriodicalId":18724,"journal":{"name":"Molecular and Cellular Biochemistry","volume":" ","pages":"5059-5074"},"PeriodicalIF":3.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144111411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Atherosclerotic plaques have been detected in multiple arterial locations, such as the aorta, carotids, and coronaries. However, it remains uncertain if there are variations in susceptibility and association among arteries of different calibers. Utilizing a spontaneous rhesus monkey model of metabolic syndrome (MetS), we assessed the susceptibility of atherosclerosis among the radial artery, femoral artery, and carotid artery and their correlation with coronary heart disease (CHD). The development of atherosclerosis in the three arteries mentioned above was evaluated by Intima-media thickness (IMT) and plaques using echo imaging over 6 years in a cohort of elderly monkeys with metabolic disorders. Coronary artery stenosis was assessed by coronary flow reserve (CFR) simultaneously. The diagnosis was further confirmed by histopathological examination, and RNA sequencing was employed to probe the transcriptional underpinnings of atherosclerotic development. The spontaneous development of atherosclerosis was observed in elderly monkeys, and the incidence of atherosclerosis was increased by three times in the MetS monkeys compared to the age-matched control group. During the 6-year follow-up, there was a notable increase in the IMT across all three arteries, with the radial artery showing the most pronounced thickening. Moreover, only the radial IMT correlated with CFR, suggesting its potential as a non-invasive diagnostic indicator for CHD. Histopathology confirmed the findings by echo imaging and identified different extracellular matrix (ECM) remodeling patterns in the arteries. In addition, transcriptomic analysis revealed that ECM remodeling and inflammation-related pathways were significantly upregulated in radial atherosclerotic samples, multiple inflammatory pathways were upregulated in the femoral lesion samples, and the carotid samples failed to enrich any pathways due to a lack of differentially expressed genes compared to the control samples. Non-human primates, which share extensive genetic and physiological similarities with humans, develop atherosclerosis spontaneously. This provides an invaluable platform for investigating the intricate mechanisms of arterial disease and evaluating potential treatments.
