    ..Thus, L-PGDS might potentially serve as an agent for prevention of human neurodegenerative diseases caused by oxidative stress and apoptosis. ..

    ..These results indicate that a plant flavonoid orientin suppressed the expression of the Ppar? gene through repression of C/ebp? expression and inhibition of the phosphoinositide 3-kinase /Akt-FOXO1 signaling in adipocytes. ..

    ..Therefore, PGF(2alpha) suppressed the progression of early phase adipogenesis after determination of the cell fate that causes MSC to differentiate into adipocytes. ..

  5. Fujimori K, Amano F. Forkhead transcription factor Foxa1 is a novel target gene of C/EBP? and suppresses the early phase of adipogenesis. Gene. 2011;473:150-6 pubmed publisher
    ..These results suggest that Foxa1 plays a suppressive role in the early phase of adipogenesis, acting under the control of C/EBP?, and might be involved in the regulation of the rate of progression of the early phase of adipogenesis. ..

  9. Kimura H, Fujimori K. Activation of early phase of adipogenesis through Krüppel-like factor KLF9-mediated, enhanced expression of CCAAT/enhancer-binding protein ? in 3T3-L1 cells. Gene. 2014;534:169-76 pubmed publisher
    ..These results indicate that KLF9 activated the early phase of adipogenesis by enhancing the expression of the C/EBP? gene in 3T3-L1 cells. ..
