Table 1. TNF mRNA steady state levels in unstimulated or LPS-stimulated FXR1-WT and KO macrophages untreated or treated with 4HPR.

A	Medium	4HPR	p valuesa
FXR1-WT	1.00±0.35	0.84±0.51	0.999
FXR1-KO	2.13±0.34	1.50±0.44	0.976
p valuesb	0.159	0.566

Results are expressed as mean ± SEM of TNF mRNA relative expression level using FXR1-WT medium as calibrator. The p values were calculated using unpaired t-test.

^a p values refer to Medium versus 4HPR or LPS versus LPS & 4HPR group.

^b p values refer to FXR1-KO versus FXR1-WT macrophages.
