YY1 and Sonic hedgehog (Shh) expressions were monitored by RT-qPCR, western blot, and immunohistochemistry. Overall survival was tested through Kaplan–Meier analysis. The interaction between YY1 and Shh was confirmed. Then, cell migration, stemness, and epithelial-mesenchymal transition (EMT) were assessed with functional experiments in vitro and in vivo. YY1 and Shh were highly expressed in NSCLC tissues and positively correlated with the poor OS of NSCLC patients. Functional experiments denoted that YY1 or Shh overexpression could accelerate EMT, migration, and stemness of NSCLC cells, and YY1 or Shh knockdown played the opposite role to its overexpression. Mechanism analysis disclosed that Shh, as a target gene of YY1, was positively related to YY1. The rescued experiment manifested that Shh silencing could reverse the induction effect of YY1 overexpression on EMT, migration, and stemness of NSCLC cells.

This worsening disease is characterized by narrowing and thickening of airways, painful cough, and dyspnea. In COPD, numerous genes as well as microRNA (miRNA) play a significant role in the pathogenesis of the disease. Many in vivo and in vitro studies suggest that upregulation or suppression of certain miRNAs are effective treatment options for COPD. They have been proven to be more beneficial than the current symptomatic treatments, such as bronchodilators and corticosteroids. MiRNAs play a crucial role in immune cell development and regulate inflammatory responses in various tissues. MiRNA treatment thus allows for precision therapy with improved outcomes. Nanoparticle drug delivery systems such as polymeric nanoparticles, inorganic nanoparticles, dendrimers, polymeric micelles, and liposomes are an efficient method to ensure the biodistribution of the miRNAs to the target site. Identification of the right nanoparticle depending on the requirements and compatibility is essential for achieving maximum therapeutic effect. In this review, we offer a thorough comprehension of the pathology and genetics of COPD and the significance of miRNAs concerning various pathologies of the lung, as potential targets for treating the disease. The present review offers the latest insights into the nanoparticle drug delivery systems that can efficiently carry and deliver miRNA or antagomirs to the specific target site and hence help in effective management of COPD.</p><h3 data-test=\"abstract-sub-heading\">Graphical abstract</h3>\u0000","PeriodicalId":18724,"journal":{"name":"Molecular and Cellular Biochemistry","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142203238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
