The colony formation assay and Cell Counting Kit-8 assay were used to determine the biological role of RBM47 in GBM. To measure invasiveness we used the wound healing assay and transwell assay. The regulatory relationship between RBM47 and the epithelial-to-mesenchymal transition (EMT) was examined by Western blot analysis and bioinformatic analysis. <b><i>Results:</i></b> Through integrative analysis of clinical proteomic and genomic tumor datasets, we found that RBM47 is significantly upregulated in GBM mesenchymal subtype, and its high expression is correlated with poor prognosis. In <i>in vitro</i> biological experiments, we observed a significant inhibitory effect of RBM47 knockdown on colony formation and cell growth using GBM cell lines. Conversely, overexpression of RBM47 restored and accelerated these processes. Moreover, <i>in vitro</i>, wound healing assays demonstrated the role of RBM46 in promoting and cell migration and invasion. Mechanistically, RBM47 enhances invasive capacity through the activation of the EMT program. In RBM47-knockdown cells, the expression levels of Vimentin and CD44 were suppressed, and the level of E-cadherin was increased. <b><i>Conclusions:</i></b> Taken together our results demonstrate the tumor promoting characteristics of RBM46 and suggest that it could be used both as a therapeutic target and prognostically.</p>","PeriodicalId":12603,"journal":{"name":"Genetic testing and molecular biomarkers","volume":"27 12","pages":"384-392"},"PeriodicalIF":1.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139073766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, we investigated the expression, clinicopathological significance, and prognostic value of MTERF3 in THCA. <b><i>Methods:</i></b> The protein and mRNA expression levels of MTERF3 were, respectively, analyzed using immunohistochemistry (IHC) from THCA tissues and RNA-Seq data downloaded from The Cancer Genome Atlas. In addition, the relationships among the expression of MTERF3, the stemness feature, the extent of immune infiltration, drug sensitivity, the expression of ferroptosis, and N6-methyladenosine (m6A) methylation regulators, were evaluated as prognostic indicators for patients with THCA using the Kaplan-Meier plotter database. <b><i>Results:</i></b> The IHC and RNAseq results showed that the protein and mRNA expression levels of MTERF3 in adjacent nontumor tissues were significantly higher than in THCA tissues. The survival analysis indicated that decreased expression of MTERF3 was associated with a poorer prognosis. Furthermore, the expression of MTERF3 not only negatively correlated with the enhancement of the stemness of THCA and the reduction of drug sensitivity but also was implicated in ferroptosis and m6A methylation. <b><i>Conclusion:</i></b> The data from this study support the hypothesis that decreased expression of MTERF3 in THCA is associated with a poor prognosis.</p>","PeriodicalId":12603,"journal":{"name":"Genetic testing and molecular biomarkers","volume":"27 12","pages":"362-369"},"PeriodicalIF":1.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139073765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In previous experiments, we found that the content of hsa-miR-1301-3p in tumor tissues of patients with nonsmall cell lung cancer (NSCLC) showed an obvious upward trend compared with that in normal tissues. We performed a detailed study on the impact and underlying mechanism of hsa-miR-1301-3p in NSCLC cells. <b><i>Methods:</i></b> The impact of hsa-miR-1301-3p on NSCLC cell proliferation, apoptosis, migration, and invasion was examined using colony formation, flow cytometry, modified Boyden chamber, and wound healing assays. Different doses of radiation were applied to NSCLC cells to investigate their sensitivity to radiotherapy. The potential target gene of hsa-miR-1301-3p was determined by dual-luciferase reporter assay and immunoblotting. <b><i>Result:</i></b> hsa-miR-1301-3p was upregulated in NSCLC tissues and cells. hsa-miR-1301-3p effectively promoted the rapid proliferation, migration, and invasion of NSCLC cells, while inhibiting apoptosis. It also induced radioresistance in NSCLC cells. hsa-miR-1301-3p targeted the homeodomain-only protein homeobox (HOPX) mRNA 3' untranslated region and inhibited its transcription in NSCLC cells.
