The purpose of the present study was to identify genes expressed in CD that are associated with ferroptosis, and to provide guidance in the diagnosis and therapy of CD. CD mRNA expression data were initially gathered from the Gene Expression Omnibus (GEO) database. GSE75214 and GSE102133 datasets were selected as the major targets and were analyzed for differentially expressed genes (DEGs). Subsequently, R software was used to analyze the common genes among the DEGs between CD and ferroptosis-related genes. Gene Ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genome pathway analysis were conducted to identify related pathways and functions. Protein-protein interaction (PPI) analysis was performed to identify target genes. The DSigDB website was used to predict potential target drugs for hub genes. Reverse transcription-quantitative (RT-q) PCR was employed to detect the expression of these ferroptosis-related genes in clinical samples obtained from healthy controls and patients with CD. According to the two GEO datasets, 13 ferroptosis DEGs (11 upregulated genes and two downregulated genes) were identified in CD with thresholds of P<0.05 and |log2 fold change|>1, and were selected for further analysis. PPI analysis indicated the mutual effects among these genes and filtered out five hub genes. The top 10 potential targeted drugs were selected. The qPCR results showed that the expression levels of three genes, namely, IL-6, prostaglandin-endoperoxide synthase 2 (PTGS2) and dual oxidase 2 (DUOX2), were different between CD samples and healthy samples. This result was consistent with the results obtained from the bioinformatics analysis. In conclusion, bioinformatics analysis identified a total of 13 ferroptosis-associated genes in CD. Further verification by qPCR showed that IL-6, PTGS2 and DUOX2 may affect the process of CD by regulating ferroptosis. These findings might provide new biomarkers, diagnostic and therapeutic markers for CD.</p>","PeriodicalId":94002,"journal":{"name":"Experimental and therapeutic medicine","volume":"27 2","pages":"89"},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10809353/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139565181","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}

The present study aimed to report a series of such cases, explore their clinical and pathological characteristics and subject all the reported cases to a survival analysis. The characteristics, management and prognosis of 10 HIV-positive patients with brain gliomas enrolled in a single hospital were investigated in detail. Immunohistochemical assessment of CD31, CD68 and CD163 was performed in the 10 HIV-positive patients with glioma and 18 HIV-negative patients with glioma. The relevant literature was also reviewed using relevant search terms. The potential predictive factors were screened by univariate and multivariate logistic regression analyses, and a nomogram was established based on the potential predictive factors. A total of 50 patients, including the 10 primary cases, were included in the survival analysis. The median survival time was 9 months. The gliomas of HIV-negative patients had a lower cell count of CD163⁺ cells than those of HIV-positive patients. High CD4⁺ T-cell count and the use of highly active antiretroviral therapy (HAART) tended to increase the median survival duration, although not significantly according to the log-rank analysis. In the univariate analysis, only surgery, radiotherapy (RT) and World Health Organization (WHO) tumor grade had significant associations with overall survival. In the multivariate analysis, only RT and WHO grade were independent predictors. In conclusion, gliomas may occur more frequently in HIV-positive populations than is currently recognized. The survival duration of most HIV-positive patients with glioma is determined by the tumor rather than HIV status. Adjuvant radiotherapy and the WHO grade of the glioma are predicted to be independent prognostic factors. Surgical resection followed by RT plus regular HAART is recommended for patients with glioma who are HIV-positive.</p>","PeriodicalId":94002,"journal":{"name":"Experimental and therapeutic medicine","volume":"27 2","pages":"90"},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10809446/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139565125","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}

Chemokine-like receptor 1 (CMKLR1), also known as chemerin receptor 23 (ChemR23) is also expressed in odontoblasts and dental pulp stem cells and is involved in inflammation suppression and tooth regeneration. Resolvin E1, a bioactive lipid, is a CMKLR1 ligand that mediates the chemerin-CMKLR1 interaction and suppresses pulpal inflammation. The present study clarified the intracellular and tissue localization of CD44 and CMKLR1 by immunohistochemical staining of normal pulp and pulp with pulpitis from 12-week-old male Wistar rat teeth or human teeth. In addition, the localization of CD44 and CMKLR1 in human dental pulp stem cells was observed by immunofluorescence staining. The present study also examined the involvement of resolvin E1 in inhibiting inflammation and calcification by western blotting. CD44- and CMKLR1-positive cells were confirmed in the odontoblast layer in normal dental pulp of rats and humans. CD44 was mainly localized in the cell membrane and CMKLR1 was mainly found in the cytoplasm of human dental pulp stem cells. CMKLR1 was also confirmed in the odontoblast layer in rats and humans with pulpitis but CD44 was not present. Following treatment of dental pulp stem cells with lipoteichoic acid, which imitates Gram-positive bacterial infection, resolvin E1 did not suppress the expression of cyclooxygenase-2 or of the odontoblast differentiation marker, dentin sialophosphoprotein. Furthermore, resolvin E1 induced the differentiation of dental pulp stem cells into odontoblasts even in the presence of the inflammatory stimulus.</p>","PeriodicalId":94002,"journal":{"name":"Experimental and therapeutic medicine","volume":"27 2","pages":"75"},"PeriodicalIF":0.0,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10804379/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139543854","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}

In this prospective study, 136 patients with high-energy pilon fractures who were treated with a locking plate combined with ankle arthroscopy from July 2015 to July 2020 were included. The treatment efficacy was evaluated according to the Mazur ankle function score. Serum caspase-1, interleukin (IL)-6, IL-1β and C-reactive protein (CRP) levels were measured using enzyme-linked immunosorbent assay. Reverse transcription-quantitative PCR was used to measure the mRNA expression of caspase-1. Additionally, demographic data and clinical characteristics, such as sex, age, intraoperative blood loss, fracture healing time, fracture classification and complications were collected and analyzed. The study revealed that the intraoperative blood loss, proportion of Ruedi-Allgower III and the serum levels of caspase-1 in the poor prognosis group were significantly higher compared with those in the good prognosis group. Additionally, patients with high-energy pilon fractures in the poor prognosis group exhibited significantly higher levels of caspase-1 and IL-1β serum levels at all time points in contrast to those in the good prognosis group. Spearman's analysis revealed a significant association between caspase-1, IL-1β levels and Mazur scores. Furthermore, caspase-1 could serve as a potential diagnostic biomarker for poor prognosis of patients with high-energy pilon fractures. Caspase-1, IL-1β, intraoperative blood loss and Ruedi-Allgower grade were the risk factors for poor prognosis in patients with high-energy pilon fractures. In summary, this study demonstrated that serum caspase-1 levels were progressively reduced during the treatment of high-energy pilon fractures patients and prominently lowered in those with a favorable prognosis. These findings could provide novel targets and a comprehensive approach to protecting patients with high-energy pilon fractures.</p>","PeriodicalId":94002,"journal":{"name":"Experimental and therapeutic medicine","volume":"27 2","pages":"77"},"PeriodicalIF":0.0,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10804377/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139543859","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}
