Ratios of mRNA levels for PPARα, PPARβ, and RXRα in Morris 7800 C1 and HepG2 cells

Ratio	Morris 7800 C1 Cells	HepG2 Cells
PPARβ/PPARα	1.89 ± 0.21	3.2 ± 0.22^1-a
PPARβ/RXRα	0.36 ± 0.05	7.6 ± 2.14^1-b
PPARα/RXRα	0.19 ± 0.03	2.4 ± 0.58^1-c

Specific mRNA levels were determined as described in Materials and Methods. Results are the mean ± S.E. of three different assays performed in duplicate.

↵1-a P = .013 versus Morris cells.
↵1-b P = .028 versus Morris cells.
↵1-c P = .019 versus Morris cells.
