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] |
