Project description:In this study, we uncover the molecular mechanism that PPARD transactive-deficient pigs have large-eared feature. Evidently from this work, PPARD plays a vital role on inhibiting cartilage growth by regulating the transcription of critical genes for chondrogenesis in ligand dependent manner; the activation of sPPARD speeds up apoptosis in CSPCs, terminal differentiation of chondroblasts and matrix degradation in auricular cartilage. The transactive-deficient PPARD has not the capability to slow down cartilage growth and consequently causes that ear size of carried animals increases at a high growth rate. As the role of PPARD in cartilage is similar in pigs, mice and humans, and since cartilage development is well-conserved in animals, our data helps to better understanding of cartilage development and treatment of cartilage-related diseases.

Project description:Peroxisome proliferator-activated receptor beta/delta (PPARD) is an important determinant of multiple biological processes. Our previous studies identified a missense mutation in the PPARD gene that significantly reduces its transcription activity, and consequently causes enlarged external ears in pigs. However, the mechanisms underlying the causality has remained largely unknown. Here, we show that PPARD retards the development of auricular cartilage by accelerating the apoptosis of cartilage stem/progenitor cells (CSPCs), the terminal differentiation of cartilage cells and the degradation of cartilage extracellular matrix in the auricle. At the transcription level, PPARD upregulates a set of genes that are associated with CSPCs apoptosis and chondrogenic differentiation, chondroblast differentiation and extracellular matrix degradation. ChIP-seq identified direct target genes of PPARD, including a well-documented gene for cartilage development: PPARG. We further show that compared to wild-type PPARD, the G32E mutant up-regulates the expression of PPARG and subsequently leads to the downregulation of critical genes that inhibit cartilage growth. These findings allow us to conclude that PPARD is an inhibitor of auricular cartilage growth in pigs. The causative mutation (G32E) in the PPARD gene attenuates the PPARD-mediated retardation of cartilage growth in the auricle, contributing to enlarged ears in pigs. The findings advance our understanding of the mechanisms underlying auricular development in mammals, and shed insight into the studies of innate pinna disorders and cartilage regeneration medicine in humans.

Project description:The PPAR (Peroxisome proliferator-activated receptor) family of nuclear receptors has three members: PPARg, PPARa and PPARd. Although they share similar structures, their biological functions are distinct. PPARg controls lipid storage and adipogenesis, while PPARd is associated with fat burning. The highly specific synthetic ligand for PPARd, GW501516, is a promising drug candidate for obesity and diabetes. Here we use Affymetrix microarray to analyze gene expression profile in mouse embryo fibroblasts treated with 100 nM GW501516 for 0, 2, 8 and 24 hours. These data may provide new clues into the molecular mechanism by which GW501516 ameliorates obesity and diabetes.

Wild type mouse embryonic fibroblasts (MEFs) stably infected with retroviruses MSCVpuro expressing PPARd were plated at 0.5 million per 10 cm dish. After overnight incubation, cells were treated with 100nM GW501516 for 0h, 2h, 8h and 48h. Cells were collected at subconfluent condition. Total RNAs were sequentially purified with Trizol (Invitrogen) and RNeasy kit (Qiagen) and analyzed in triplicate on Mouse Genome 430 2.0 Array (Affymetrix) at NIDDK Microarray Core Facility following standard protocols.

Project description:The role of murine peroxisome proliferator-activated receptor-delta (PPARd) in mammary tumorigenesis was assessed. Microarrays were used to analyse global gene expression to determine changes in MMTV-PPARd transgenic mice versus wild-type mice and the effect of GW501516.
