Journal ArticleDOI

TL;DR: It is shown that rhythmic transcription extends to the locus specifying miR-122, a highly abundant, hepatocyte-specific microRNA, and the identification of Pparbeta/delta and the peroxisome proliferator-activated receptor alpha (PPARalpha) coactivator Smarcd1/Baf60a as novel miR,122 targets suggests an involvement of the circadian metabolic regulators of the PPAR family in miR -122-mediated metabolic control.
Journal ArticleDOI
Hepatic ceramides dissociate steatosis and insulin resistance in patients with non-alcoholic fatty liver disease
Panu K. Luukkonen,Panu K. Luukkonen,You Zhou,Sanja Sädevirta,Sanja Sädevirta,Marja Leivonen,Johanna Arola,Matej Orešič,Tuulia Hyötyläinen,Hannele Yki-Järvinen,Hannele Yki-Järvinen +10 more
TL;DR: Similar increases in liver fat and NASH are associated with a metabolically harmful saturated, ceramide-enriched liver lipidome in 'Metabolic NAFLD' but not in 'PNPLA3NAFLD', which may explain why metabolic but not PNPLA3 NAFLd increases the risk of type 2 diabetes and cardiovascular disease.
Journal ArticleDOI
Pathways to the analysis of microarray data
TL;DR: Several methods of pathway analysis are reviewed and the performance of three, the binomial distribution, z scores, and gene set enrichment analysis, on two microarray datasets are compared.
Journal ArticleDOI
Gene-to-metabolite networks for terpenoid indole alkaloid biosynthesis in Catharanthus roseus cells
Heiko Rischer,Matej Orešič,Tuulikki Seppänen-Laakso,Mikko Katajamaa,Freya Lammertyn,Wilson Ardiles-Diaz,Marc Van Montagu,Dirk Inzé,Kirsi-Marja Oksman-Caldentey,Alain Goossens +9 more
TL;DR: A comprehensive profiling analysis of the Madagascar periwinkle (Catharanthus roseus), a source of the anticancer drugs vinblastine and vincristine, provides the basis for a better understanding of periwinkles secondary metabolism and increases the practical potential of metabolic engineering of this important medicinal plant.
Journal ArticleDOI
Adipose Tissue Inflammation and Increased Ceramide Content Characterize Subjects With High Liver Fat Content Independent of Obesity
Maria Kolak,Jukka Westerbacka,Vidya Velagapudi,Dick Wågsäter,Laxman Yetukuri,Janne Makkonen,Aila Rissanen,Anna-Maija Häkkinen,Monica Lindell,Robert Bergholm,Anders Hamsten,Per Eriksson,Rachel M. Fisher,Matej Orešič,Hannele Yki-Järvinen,Hannele Yki-Järvinen +15 more
TL;DR: Adipose tissue is infiltrated with macrophages, and its content of long-chain triacylglycerols and ceramides is increased in subjects with increased LFAT compared with equally obese subjects with normal LFAT content, which could contribute to adverse effects of long chain fatty acids on insulin resistance and inflammation.
