Table 2. Binding of C/EBP-β and PU.1 on the 5′ promoter region of Il1β and Il6 in WT and p65 Δmye peritoneal MΦs.
ChIP data reveal that there is a significantly increased binding of C/EBP-β and PU.1 on Il1b and Il6 promoters in p65 Δmye peritoneal MΦs. The amount of immunoprecipitated DNA was analyzed by real-time PCR and then normalized over the respective input control.
| Transcription factor | Enrichment over negative control (Gapdh intronic region) | |||
|---|---|---|---|---|
| Peritoneal MΦs | ||||
| Il1b | Il6 | |||
| WT | p65Δmye | WT | p65Δmye | |
| C/EBP-β | 1.60(n.s.) | 2.64* | 60.02(n.s.) | 266.34* |
| PU.1 | 1.41(n.s.) | 34.73* | 0 (n.s.) | 336.62* |
Data in the table represent the fold increase of immunoprecipitated DNA for Il1b or Il6 over a negative control DNA fragment (Gapdh intronic region).
p < 0.05 vs. negative control; n=2 for each group;
Il1b: interleukin 1b; Il6: interleukin 6; MΦs: macrophages; n.s.: not significant.
