Abstract Members of the family of nuclear receptors that include peroxisome proliferator-activated receptors (PPARs) and retinoid X receptors (RXRs) are important mediators of selective gene activation during development and cellular differentiation. In this study, developmentally-specific PPAR and RXR patterns of expression that occur in somatic and germ cell populations in the testis were determined using quantative real-time PCR (qRT-PCR) studies on RNAs that were isolated from StaPut purified mouse germ cells and primary rat Sertoli cells. These qRT-PCR studies indicate that transcripts encoding the PPAR-Alpha (alpha), -Beta (beta), and -Gamma (gamma) and RXR -Alpha (alpha), -Beta (beta), and -Gamma (gamma) are developmentally expressed in both differentiating germ and Sertoli cells. In further experiments aimed at deciphering the physiological role that PPAR-Gamma (gamma) plays in Sertoli cells, 15-day primary rat Sertoli cells were infected with recombinant adenoviral vectors containing PPAR-Gamma (gamma) cDNA and PPAR-Gamma (gamma) RNAi constructs. Affymetrix microarray analysis and qRT-PCR validation studies using total RNA isolated from these transfected cells indicated that PPAR-Gamma regulates the pattern of expression of key lipid metabolic genes in Sertoli cells.
