Expression of peroxisome proliferator-activated receptor γ, coactivator 1β (PPARGC1B) mRNA. Increased PPARGC1B mRNA levels were found in the lungs of DEP-exposed OLETF obese rats compared to those in the DEP-exposed LETO non-obese rats. RNA was isolated from lung tissue and analyzed by reverse-transcription polymerase chain reaction (RT-PCR). DEP indicates diesel exhaust particles; mRNA, messenger RNA; OLETF, Otsuka Long Evans Tokushima Fatty; LETO, Long Evans Tokushima-Otsuka.
