The nuclear paraspeckle assembly transcript 1 (NEAT1) is a long non-coding RNA (lncRNA) that exhibits increased expression in female tumors. Moreover, elevated levels of NEAT1 have been associated with poorer survival outcomes in cancer patients. NEAT1 plays a pivotal role in driving tumor initiation through modulating the expression of genes involved in various aspects of tumor cell proliferation, epithelial-to-mesenchymal transition (EMT), metastasis, chemoresistance, and radio-resistance. Mechanistically, NEAT1 acts as a scaffold RNA molecule via interacting with EZH2 (Enhancer of Zeste 2 Polycomb Repressive Complex 2 Subunit), thereby influencing the expression of downstream effectors of EZH2. Additionally, NEAT1 functions as a competing endogenous RNA (ceRNA) by microRNAs (miRNAs) sponging, consequently altering the expression levels of their target genes during the development of female cancers. This comprehensive review aims to shed light on the latest insights regarding the expression pattern, biological functions, and underlying mechanisms governing the function and regulation of NEAT1 in tumors.

P53 is the most commonly mutated gene in osteosarcoma and plays an important role in the development and metastasis of osteosarcoma. The ubiquitin proteasome system is an evolutionarily conserved post-translational modification that regulates a variety of disease processes, including tumors. Researches have shown that RFWD2, as a function of an E3 ubiquitin ligase, plays an important role in regulating tumor progression. However, the biological function of RFWD2 in osteosarcoma cells with different p53 status remains to be clarified. Initially, we found that sarcoma patients with high levels of RFWD2 expression tended to have shorter overall survival time by analyzing UALCAN-TCGA data. Subsequently, we used CCK-8, colony formation, Transwell, and xenograft methods to confirm that RFWD2 acts as an oncogene, regulating the proliferation and invasion of osteosarcoma cells (HOS<sup>(p53mut/-)</sup>, U2OS<sup>(p53wt/wt)</sup> and Saos-2<sup>(p53-/-)</sup> cells) with different p53 status.

In addition, we demonstrated through both <em>in vitro</em> and <em>in vivo</em> experiments that RFWD2 regulates the sensitivity of osteosarcoma cells to CDDP.

Critical genes were pinpointed by integrating GO, KEGG and PPI networks. Furthermore, CIBERSORTx analysis was used to investigate the differences in immune cell infiltration between different groups and the biological processes (BP), cellular components (CC) and molecular functions (MF) were calculated by GSEA and GSVA. In addition, The single-cell database GSE165722 was incorporated to validate the specific expression patterns of hub genes in cells and identify distinct cell subtypes. This provides a theoretical basis for a more in-depth understanding of the roles played by critical cell subtypes in the process of IDD.

Cyclic di-guanosine monophosphate (c-di-GMP), a secondary messenger in bacteria, controls multiple bacterial behaviors including pathogenesis, the development of biofilms, and motility. The protein GefB (VPA1478), characterized by the presence of a GGDEF domain, inhibits the swarming motility of <em>V. parahaemolyticus</em>. In this study, we showed that deletion of <em>gefB</em> remarkably reduced cellular c-di-GMP level and biofilm formation by <em>V. parahaemolyticus</em>, but significantly enhanced the swimming and swarming motility. In addition, GefB inhibited the polar and lateral flagellar genes but activated genes associated with exopolysaccharide production of <em>V. parahaemolyticus</em>. The data also demonstrated that <em>vpa1477</em> and <em>gefB</em> are co-transcribed as a single transcriptional unit, designated as <em>vpa1477</em>-<em>gefB</em>. Transcription of <em>vpa1477</em>-<em>gefB</em> was under the collective regulation of the master quorum sensing (QS) regulators AphA and OpaR, which function at low (LCD) and high cell density (HCD), respectively. AphA positively regulated <em>vpa1477</em>-<em>gefB</em> transcription at LCD, whereas OpaR negatively regulated its transcription at HCD. The findings significantly enhance our comprehension of the metabolism and regulatory mechanisms of c-di-GMP in <em>V. parahaemolyticus</em>.</div></div>","PeriodicalId":12499,"journal":{"name":"Gene","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142344762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
