However, few studies have reported on genetic associations between FA and ferroptosis. Our study evaluated the usefulness of genes related to ferroptosis in predicting and diagnosing FA. Transcriptome sequencing data were collected from 11 normal participants and 21 patients with FA. Differential gene analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG), Gene Ontology (GO) analysis, gene correlation analysis, protein-protein interaction network analysis, qRT-PCR, and pan-cancer analysis were performed. The pan-cancer analysis was carried out based on data obtained from the GTEx and TCGA databases. Two hundred ninety-eight differentially expressed genes were detected based on the comparison of FA patients and normal participants, among which four critical non-FA genes, MAD2L1, ASPM, PCNA, and TOP2A, were identified. Among the ferroptosis-related genes, five genes, including CDKN1A, EMC2, FDFT1, HSPB1, and MT1G, were identified as being associated with FA, and the areas under the curve (AUC) of these five ferroptosis-related genes were 0.907, 0.640, 0.902, 0.840, and 0.929, respectively. The AUC for the diagnosis of FA reached 1.000 when the five ferroptosis-related genes were used in combination. In addition, the expressions of CDKN1A, EMC2, FDFT1, and HSPB1 were associated with the prognosis of multiple cancers (P<0.05). The five ferroptosis-related genes CDKN1A, EMC2, FDFT1, HSPB1, and MT1G exhibited excellent predictive effects for the diagnosis of FA.</p>","PeriodicalId":20235,"journal":{"name":"Physiological research","volume":"74 2","pages":"275-285"},"PeriodicalIF":1.9,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12148158/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its global prevalence increases annually, significantly affecting quality of life. Only a few patients manage to alleviate NAFLD through lifestyle modifications. The pathogenic mechanisms and therapeutic targets of this disease remain inadequately explored. In recent years, many studies highlighted a close relationship between the thyroid-stimulating hormone (TSH) and NAFLD. TSH has been shown to promote fat accumulation in the liver by participating in the ab initio synthesis, uptake and secretion of lipids. Moreover, TSH exacerbates hepatocyte inflammation and fibrosis by inducing endoplasmic reticulum stress and promoting the release of inflammatory factors. Although some of the conclusions remain controversial and are subject to debate, exploring the connection and possible pathways between TSH and NAFLD is crucial. Such research could advance early clinical prevention and intervention strategies, thereby reducing the incidence of severe NAFLD-associated comorbidities.

Here, we explored the role and molecular mechanism of BBR in Alzheimer's disease (AD) progression. Weighted gene co-expression network analysis (WGCNA) was conducted to determine AD pathology-associated gene modules and differentially expressed genes (DEGs) were also identified. GO and KEGG analyses were performed for gene function and signaling pathway annotation. Cell counting kit-8 (CCK8) assay was applied to analyze cell viability. Immunofluorescence (IF) staining assay was conducted to measure the levels of polarization markers. The production of inflammatory cytokines was analyzed by enzyme-linked immunosorbent assay (ELISA). Reactive oxygen species (ROS) level and mitochondrial membrane potential (MMP) were detected using a ROS detection kit and a MMP Detection Kit (JC-1), respectively. AD pathology-associated DEGs were applied for GO function annotation and KEGG enrichment analysis, and the results uncovered that AD pathology was related to immune and inflammation. Lipopolysaccharide (LPS) exposure induced the M1 phenotype of microglia, and BBR suppressed LPS-induced M1 polarization and induced microglia toward M2 polarization. Through co-culture of microglia and neuronal cells, we found that BBR exerted a neuro-protective role by attenuating the injury of LPS-induced HMC3 on SH-SY5Y cells. Mechanically, BBR switched the M1/M2 phenotypes of microglia by activating PI3K-AKT signaling. In summary, BBR protected neuronal cells from activated microglia-mediated neuro-inflammation by switching the M1/M2 polarization in LPS-induced microglia via activating PI3K-AKT signaling.

Three common AKI cell models were constructed, classified into the control group (human renal tubular epithelial cells [HK-2] cells), the Iohexol group (HK-2 cells treated with Iohexol), the Genta group (HK-2 cells treated with Gentamicin), and the Cis group (HK-2 cells treated with Cisplatin). To explore the optimal protective concentration of Mdivi-1 for each AKI cell model, the experimental design consisted of the following seven groups: the control group (HK-2 cells cultured in medium), three injury groups (HK-2 cells subjected to Iohexol, Gentamicin, or Cisplatin), and the corresponding protection groups (with a certain concentration of Mdivi-1 added to each injury group). Cellular survival and apoptosis, reactive oxygen species (ROS) levels, and the expression of recombinant Sirtuin 3 (SIRT3) in each group were measured. Mitochondrial fission and fusion dynamics in cells were observed under an electron microscope. To explore relevant pathways, the changes in relevant pathway proteins were analyzed through Western blotting. The half maximal inhibitory concentration (IC50) values were 150.06 mgI/ml at 6 h in the Iohexol group, 37.88 mg/ml at 24 h in the Gentamicin group, and 13.48 microM at 24 h in the Cisplatin group. Compared with the control group, the three injury groups showed increased cell apoptosis rates and higher expressions of apoptotic proteins in HK-2 cells, with an accompanying decrease in cell migration. After the addition of corresponding concentrations of Mdivi-1, the optimal concentrations were 3 µM in the Iohexo-3 group, 1 microM in the Genta-1 group, and 5 µM in the Cis-5 group, HK-2 cells showed the highest survival rate, reduced apoptosis, decreased mitochondrial ROS and SIRT3 expression, and reduced mitochondrial fission and autophagy when compared with each injury group. Further verification with Western blot analysis after the addition of Mdivi-1 revealed a reduction in the expressions of mitochondrial fission proteins DRP1, Nrf2, SIRT3, Caspase-3, Jun N-terminal Kinase (JNK)/P-JNK, NF-kappaB, Bcl2, and autophagic protein P62, as well as reduced ROS levels. Mdivi-1 had protective effects on the three common AKI cell models by potentially reducing mitochondrial fission in cells and inhibiting the production of ROS through the mediation of the NF- B/JNK/SIRT3 signaling pathway, thereby exerting protective effects.

Twenty-four APP/PSl double transgenic mice were randomly assigned to either Group A or Group B, while another 24 C57 mice were randomly allocated to Group C or Group D. HBOT was administered to mice in Group B and Group D, and the Morris water maze test was used to assess changes in mice behavior. Histological examination using hematoxylin and eosin staining was conducted to observe pathological alterations in the hippocampus of the mice brain tissue. Polymerase chain reaction (PCR) was employed to analyze autophagy-related gene pathways in the hippocampus of the mice. Following HBOT, mice in Group B exhibited a significant reduction in escape latency and a notable increase in residence time within the target quadrant compared with Group A (P<0.05), as well as Group C and Group D (P<0.01). The hippocampal neurons in Group A and Group B mice exhibited disorganized arrangements, characterized by pyknosis and margination. Conversely, neurons in Group C displayed orderly arrangements, retaining intact structures with round nuclei demonstrating clear nuclear staining and normal morphology. The cellular morphology of mice in Group D remained unaffected. PCR analysis revealed no notable disparity in autophagy-related gene expression between Group A and Group C. However, the expression levels of five genes including Tgfb1, Mapk14, Bid, Atg7, and Akt1, were significantly elevated in Group B compared to Group A. HBOT has the potential to improve the cognitive function in mice modeled with AD. This improvement of cognitive function appears to be mediated by the up-regulation of autophagy-related genes, specifically Tgfb1, Mapk14, Bid, Atg7, and Akt1.
