Table 2. Relative expression of PPARβ/δ in the small and large intestine.

Species Specimen Relative expression Method Reference
Rat 300 g Sprague–Dawley Relatively high expression of mRNA encoding PPARβ/δ in the small intestine and colon In situ hybridization [172]
Mouse 7-week-old NMRI Modest expression of mRNA encoding PPARβ/δ in the colon, less expression of mRNA encoding PPARβ/δ in the small intestine Ribonuclease protection assay [173]
Human 7–22-week fetuses; adult controls Expression of PPARβ/δ protein is higher in the adult colon compared with fetal colon; appears to move from cytoplasm to nucleus with age Western blotting and immunohistochemistry [34]
Rat 8–9-weeks-old (approx. 200 g) Sprague–Dawley Markedly high expression of mRNA encoding PPARβ/δ compared with other tissues and other PPARs Ribonuclease protection assay [32]
Rat 5 and 25 days postnatally; Sprague–Dawley High expression of mRNA encoding PPARβ/δ compared with other PPARs in the small intestine; increased expression of mRNA encoding PPARβ/δ by postnatal day 25. Northern blotting [174]
Mouse 5–6-weeks-old CD-1 Relatively high expression of PPARβ/δ protein in intestinal epithelial cells; expressed in cryptic cells Tissue microarray-based immunohistochemistry [37]
