| Pubmed ID: | 24086551 |
| Enhancer experiment: | qRT-PCR,Luciferase Reporter Assay,ChIP-seq,ChIP-qPCR | |
| Enhancer experiment description: | We have analyzed the miR-200b~200a~429 locus for epigenetic modifications in breast epithelial and mesenchymal cell lines using chromatin immunoprecipitation assays and DNA methylation analysis. We discovered a novel enhancer located approximately 5.1kb upstream of the miR-200b~200a~429 transcriptional start site. This region was associated with the active enhancer chromatin signature comprising H3K4me1, H3K27ac, RNA polymerase II and CpG dinucleotide hypomethylation. |
About Target gene
| Target gene : | GIHCG(GIHCG) | |
| Strong evidence: | -- | |
| Less strong evidence: | qRT-PCR,Luciferase Reporter Assay,ChIP-qPCR | |
| Target gene experiment description: | Luciferase reporter assays revealed the upstream enhancer stimulated the transcription of the miR-200b~200a~429 minimal promoter region approximately 27-fold in breast epithelial cells. Furthermore, we found that a region of the enhancer was transcribed, producing a short, GC-rich, mainly nuclear, non-polyadenylated RNA transcript designated miR-200b eRNA. |

About Function
| Enhancer function : | The presence of a novel Enhancer contributes to miR-200b~200a~429 transcriptional regulation in epithelial cells. |
| Enhancer function experiment: | Luciferase Reporter Assay |
| Enhancer function experiment description: |
Luciferase reporter assays revealed the upstream enhancer stimulated the transcription of the miR-200b~200a~429 minimal promoter region approximately 27-fold in breast epithelial cells. Furthermore, we found that a region of the enhancer was transcribed, producing a short, GC-rich, mainly nuclear, non-polyadenylated RNA transcript designated miR-200b eRNA. Over-expression of miR-200b eRNA had little effect on miR-200b~200a~429 promoter activity and its production did not correlate with miR-200b~200a~429 gene expression. |
