Eugenol inhibits NEAT1 as a ceRNA in pre-cancerous breast lesions

Year: 2024

Abstract: Objective Eugenol (EU) from cloves is highly effective against different tumors. The long noncoding ribonucleic acids (lncRNAs), which play a role of competing endogenous RNAs (ceRNAs), suppress microRNAs (miRNAs) involved in post-transcriptional regulatory networks. The present work focused on analyzing how EU affected pre-cancerous breast lesions (PBL). Methods Initially, the gene expression profiles of patients (n = 880) in the National Center for Biotechnology Information (NCBI) database were analyzed. Further, we established a lncRNA-miRNA-mRNA ceRNA network through bioinformatics analysis and investigated mechanistic roles of lncRNAs as ceRNAs and the anti-tumor effect of EU using MCF-10AT cells in vitro as well as PBL model rats in vivo . Besides, Nuclear Paraspeckle Assembly Transcript 1 (NEAT1), miR-383-5p, miR-9-5p, matrix metalloproteinase-9 (MMP-9), and vascular endothelial growth factor-A (VEGF-A) expression was examined through quantitative reverse transcription polymerase chain reaction (RT-qPCR), Western blotting, and immunohistochemical staining analyses. Results There were altogether 1162 mRNAs, 81 miRNAs, and 26 lncRNAs recognized as trend genes in breast cancer (BC) and pre-cancerous BC (pBC), constructing the ceRNA network using 3 lncRNAs, 3 miRNAs, and 38 mRNAs. It was observed that NEAT1, miR-383-5p, miR-9-5p, VEGF-A, and MMP-9 were downregulated in breast tumor cells in accordance with bioinformatics analysis. EU suppressed MCF-10AT cell growth, decreasing the NEAT1, VEGF-A, and MMP-9 levels and increasing miR-383-5p and miR-9-5p expressions in vitro and in vivo . Conclusion In summary, the EU reduced the VEGF-A and MMP-9 expressions via NEAT1-mediated miR-383-5p and miR-9-5p against PBL, indicating that the EU may be a promising external drug to act against PBL.
