The effects of &lt;i&gt;SPINK5&lt;/i&gt; on the invasion and migration of ESCC cells were assessed using Transwell assays.

Moreover, the correlation between expression of &lt;i&gt;SPINK5&lt;/i&gt; and nuclear factor-kappa B (NF-κB) signaling pathway-related genes was analyzed in the TCGA-ESCC cohort, and the effects of &lt;i&gt;SPINK5&lt;/i&gt; on NF-κB transcription was analyzed using a luciferase reporter gene assay.

Recent research indicates that copy number variation plays a crucial role in tumor development.

Using the SCEVAN algorithm, we distinguished malignant from non-malignant cells and investigated cellular interactions within the tumor microenvironment (TME). We categorized TCGA samples based on differentially expressed genes (DEGs) between these cell types. Subsequent Kyoto Encyclopedia of Genes and Genomes pathway analysis was conducted. Additionally, we developed polygenic models for the DEGs using least absolute shrinkage and selection operator-penalized Cox regression analysis. To assess the prognostic accuracy of these characteristics, we generated Kaplan–Meier and receiver operating characteristic curves from training and validation datasets. We also monitored the expression variations of prognostic genes across the pseudotime of malignant cells. Patients were divided into high-risk and low-risk groups based on median risk scores to compare their TME and identify potential therapeutic agents.

The effects of FTH1 on migration, invasion, epithelial–mesenchymal transition (EMT) and proliferation were determined by wound healing assays, transwell assays, western blotting and 5′-ethynl 2′-deoxyuridine proliferation assays, respectively. The effects of FTH1 on ferroptosis were tested via ferroptosis markers and Mito Tracker staining. In addition, the therapeutic effects of baicalin on OSCC cells were confirmed using EMT, migration, invasion, proliferation and ferroptosis assays.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The 12 FRGs were predictive of the prognosis for OSCC patients, and FTH1 expression was identified as significantly up-regulated in OSCC samples, which was highly associated with survival, immune cell infiltration and drug sensitivity. Moreover, knocking down FTH1 inhibited cell proliferation, EMT and invasive phenotypes, but induced ferroptosis in OSCC cells (Cal27 and SCC25). Furthermore, baicalin directly suppressed expression of FTH1 in OSCC cells, and effectively promoted ferroptosis and inhibited the proliferation as well as EMT by directly targeting FTH1.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>This study has demonstrated that FTH1 is a therapeutic target for OSCC treatment, and has provided evidence that baicalin offers a promising alternative for OSCC treatment.</p>\u0000 </section>\u0000 </div>","PeriodicalId":56122,"journal":{"name":"Journal of Gene Medicine","volume":"26 2","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139914145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a neurological disease that affects nerve cell development and function, resulting in severe motor and intellectual disabilities. To date, no cure is available for treating this disease. In 90% of the cases, RTT is caused by a mutation in methyl-CpG-binding protein 2 (MECP2), a transcription factor involved in the repression and activation of transcription. MECP2 is known to regulate several target genes and is involved in different physiological functions. Mouse models exhibit a broad range of phenotypes in recapitulating human RTT symptoms; however, understanding the disease mechanisms remains incomplete, and many potential RTT treatments developed in mouse models have not shown translational effectiveness in human trials. Recent data hint that the zebrafish model emulates similar disrupted neurological functions following mutation of the <i>mecp2</i> gene. This suggests that zebrafish can be used to understand the onset and progression of RTT pathophysiology and develop a possible cure. In this review, we elaborate on the molecular basis of RTT pathophysiology in humans and model organisms, including rodents and zebrafish, focusing on the zebrafish model to understand the molecular pathophysiology and the development of therapeutic strategies for RTT. Finally, we propose a rational treatment strategy, including antisense oligonucleotides, small interfering RNA technology and induced pluripotent stem cell-derived cell therapy.</p>","PeriodicalId":56122,"journal":{"name":"Journal of Gene Medicine","volume":"26 2","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139914147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
