先天性巨结肠是一种严重的先天性疾病,其病因至今仍不清楚。许多研究强调了内含子miRNAs及其宿主基因在各种疾病中的重要作用,但在HSCR中很少提及。在这项研究中,发现miR-483 - 3 p沿着其宿主基因IGF 2(胰岛素样生长因子2)在60例HSCR无神经节结肠组织中与60例正常对照相比下调。通过双荧光素酶报告基因分析确定FHL 1(四个半LIM结构域1)为miR-483 - 3 p的靶基因,其在HSCR组织中的表达水平较高。在这里,我们通过进行Transwell和CCK 8测定来研究人293 T和SH-SY 5 Y细胞系的细胞迁移和增殖。总之,miR-483 - 3 p和IGF 2的敲低均抑制细胞迁移和增殖,而FHL 1的缺失导致相反的结果。此外,miR-483 - 3 p模拟物可以挽救由沉默IGF 2引起的对细胞增殖和迁移的负面影响,而FHL 1 siRNA可以逆转miR-483 - 3 p抑制剂的功能。这项研究揭示了IGF 2来源的miR-483 - 3 p通过靶向FHL 1与先天性巨结肠相关,并可能为理解HSCR的病因提供新的途径。
HSCR (Hirschsprung's disease) is a serious congenital defect, and the aetiology of it remains unclear. Many studies have highlighted the significant roles of intronic miRNAs and their host genes in various disease, few was mentioned in HSCR although. In this study, miR‐483‐3p along with its host gene IGF2 (Insulin‐like growth factor 2) was found down‐regulated in 60 HSCR aganglionic colon tissues compared with 60 normal controls. FHL1 (Four and a half LIM domains 1) was determined as a target gene of miR‐483‐3p via dual‐luciferase reporter assay, and its expression was at a higher level in HSCR tissues. Here, we study cell migration and proliferation in human 293T and SH‐SY5Y cell lines by performing Transwell and CCK8 assays. In conclusion, the knockdown of miR‐483‐3p and IGF2 both suppressed cell migration and proliferation, while the loss of FHL1 leads to opposite outcome. Furthermore, miR‐483‐3p mimics could rescue the negative effects on cell proliferation and migration caused by silencing IGF2, while the FHL1 siRNA may inverse the function of miR‐483‐3p inhibitor. This study revealed that miR‐483‐3p derived from IGF2 was associated with Hirschsprung's disease by targeting FHL1 and may provide a new pathway to understand the aetiology of HSCR.
