Effects of LPS on RNA levels of NRs and RXRα target genes. C57BL/6 mice were injected with 0.9% saline (white bars) or 2 μg/g bw of Salmonella LPS (black bars) for 16 hours (n = 6 per group). RNA was prepared from the livers and analyzed for A. NRs and B. RXRα target genes by real-time PCR. All data were presented as mean ± SD and standardized for GAPDH RNA levels. Expression in the saline-treated control animals was set to 1. The asterisks indicate significant difference (p < 0.05). See supplemental information for primers and probes.
