| Biosample name: | MCF-7 | |
| Experiment class : | Low throughput |
| Enhancer type: | Enhancer | |
| Disease: | -- | |
| DO: | -- | |

| Distance from TSS: | >2KB | |
| Pubmed ID: | 25786345 |
| Enhancer experiment: | Luciferase Reporter Assay,PCR | |
| Enhancer experiment description: | Genomic fragment containing cxcr5 promoter was subcloned upstream of luciferase gene in pGL3-Basic reporter vector. Another genomic fragment containing the potential cxcr5 enhancer was subcloned downstream of the luciferase gene. In order to account for lower transfection efficiency of larger plasmids, the second construct included a control genomic fragment from cxcr5 locus which was similar in length to the enhancer fragment but had no characteristic features of a regulatory sequence. Functional comparison of these two constructs in MCF-7 and MCF-7-2si cells (Figure 3A) revealed a marginal modulating effect by the enhancer (15%) towards cxcr5 promoter activity. This effect, however, was stable in both cell lines, indicating that activity of the cxcr5 intronic enhancer in breast cancer cells was independent of the p53 status. |
