We then carried out Gene Ontology (GO) enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and gene set enrichment analysis (GSEA). Furthermore, we investigated the correlations between SPARCL1 and immunological features, such as tumour mutation burden (TMB), immune activation processes, immune checkpoint expression, tumour immune dysfunction and exclusion (TIDE) scores, and chemotherapeutic sensitivity in BCa. Our analysis revealed that SPARCL1 was downregulated across multiple cancers. In BCa, elevated SPARCL1 was linked with advanced histopathologic stage, higher T and N stage, and poorer prognosis in the clinical cohort. In vitro experiments demonstrated that increased SPARCL1 expression inhibited cell proliferation, migration, and invasion. Additionally, highly expressed SPARCL1 was linked to elevated immune, stromal and ESTIMATE scores, as well as an increase in naive B cells, M2 macrophages, and resting mast cells. We observed a moderate correlation between SPARCL1 expression and CD163, VSIG4 and MS4A4A, which are markers of M2 macrophages. Furthermore, SPARCL1 expression was positively related to TMB, immune activation processes, TIDE scores, immune checkpoint expression, and chemotherapeutic sensitivity in BCa.

Flubendazole, an FDA-approved antiparasitic drug, has been shown to target p53 and promote apoptosis in glioblastoma (GBM) cells. However, its damaging mechanism in GBM remains elusive. Herein, we explored the ferroptosis-inducing ability of flubendazole on GBM cells. After treating glioma cell lines U251 and LN229 with the flubendazole (DMSO &lt;1‰), cell viability was inhibited in a concentration-dependent manner (IC<sub>50</sub> for LN229 = 0.5331 μM, IC<sub>50</sub> for U251 = 0.6809 μM), attributed to the induction of ferroptosis, as evidenced by increased MDA levels, accumulation of ROS and lipid peroxides, change in mitochondrial membrane potential and structure. Protein analysis related to ferroptosis showed upregulation of TFRC, DMT1 and p53, alongside downregulation of xCT, FHC and GPX4 (<i>p</i> &lt; 0.05). All-atom docking studies demonstrated that flubendazole bound closely with xCT, and TFRC, validating its role in inducing glioma ferroptosis via modulation of these proteins.

The pharmacological effects of esculetin (ELT), such as antibacterial and anti-inflammatory actions, have been widely confirmed. However, the therapeutic effects and mechanisms of ELT on SALI still need to be further clarified. In this study, we first evaluated the therapeutic potential of ELT on a caecal ligation and puncture (CLP) induced septic rat model, particularly in the treatment of acute lung injury. Afterwards, we explored the effect of ELT on macrophage polarization in vivo and in vitro. Then, we investigated the anti-inflammatory mechanism of ELT based on modulating the metabolic reprogramming of macrophage (the effect on glycolysis in M1, and the effect on fatty acid β-oxidation in M2). In addition, macrophage metabolic inhibitors (glycolysis inhibitor: 2-DG, and fatty acid β-oxidation inhibitor: etomoxir) were used to verify the regulatory effect of ELT on macrophage metabolic reprogramming. Our results proved that ELT intervention could effectively improve the survival rate of SALI rats and ameliorate pathological injury. Next, we found that ELT intervention inhibited M1 polarization and promoted M2 polarization of macrophages in vivo and in vitro, including the downregulation of M1-related markers (CD86, iNOS), the decrease of pro-inflammatory factors (nitric oxide, IL-1β, IL-6, and TNF-α), the upregulation of M2-related markers (CD206, ARG-1), the increase of immunomodulatory factors (IL-4 and IL-10). Subsequently, seahorse analysis showed that ELT intervention inhibited the glycolytic capacity in M1, and promoted the ability of fatty acid β-oxidation in M2. Besides, ELT intervention inhibited the level of glycolysis product (lactic acid), and the expression of glycolysis-related genes (<i>Glut1</i>, <i>Hk2</i>, <i>Pfkfb1</i>, <i>Pkm</i> and <i>Ldha</i>) and promoted the expression of fatty acid β-oxidation related genes (<i>Cpt1a</i>, <i>Cpt2</i>, <i>Acox1</i>). In addition, we found that the inhibitory effect of ELT on M1 polarization was comparable to that of 2-DG, while intervention with etomoxir abolished the promoting effect of ELT on M2 polarization. ELT inhibited the inflammatory response in SALI by correcting macrophage polarization (inhibiting M1 and promoting M2). The mechanism of ELT on macrophage polarization was associated with regulating metabolic reprogramming (inhibiting glycolysis in M1 and promoting fatty acid β-oxidation in M2).</p>","PeriodicalId":101321,"journal":{"name":"JOURNAL OF CELLULAR AND MOLECULAR MEDICINE","volume":"28 21","pages":""},"PeriodicalIF":5.3,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11558263/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142621367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, gene set enrichment analysis (GSEA) was conducted to detect downstream signalling pathways. Furthermore, experimental validation was carried out using hearts from spontaneously hypertensive rats (SHRs). A comprehensive analysis revealed the identification of 208 differentially expressed genes (DEGs) in female patients with HCM with a notable downregulation of seven core genes. Notably, there were sex differences in the expression of ras dexamethasone-induced protein 1 (RASD1) and myosin 6 (MYH6) in HCM. Gene ontology (GO) analysis and GSEA demonstrated an enrichment of autophagy-related processes in disease progression in HCM females.

In this study, we aimed to investigate the effects of fibroblast-derived miR-425-5p in pressure overload-induced HF and explore the underlying mechanisms. C57BL/6 mice were injected with a recombinant adeno-associated virus specifically designed to overexpress miR-425-5p in CFs, followed by transverse aortic constriction (TAC) surgery. Neonatal mouse CFs (NMCFs) were transfected with miR-425-5p mimics and subsequently stimulated with angiotensin II (Ang II). We found that miR-425-5p levels were significantly downregulated in HF mice and Ang II-treated NMCFs. Notably, fibroblast-specific overexpression of miR-425-5p markedly inhibited the proliferation and differentiation of CFs, thereby alleviating myocardial fibrosis, cardiac hypertrophy and systolic dysfunction.
