Myogenic gene expression signature establishes that brown and white adipocytes originate from distinct cell lineages

JA Timmons, K Wennmalm, O Larsson… - Proceedings of the …, 2007 - National Acad Sciences
Attainment of a brown adipocyte cell phenotype in white adipocytes, with their abundant
mitochondria and increased energy expenditure potential, is a legitimate strategy for combating …

Polysome fractionation and analysis of mammalian translatomes on a genome-wide scale

…, T Alain, M Morita, S McLaughlan, O Larsson… - JoVE (Journal of …, 2014 - jove.com
mRNA translation plays a central role in the regulation of gene expression and represents the
most energy consuming process in mammalian cells. Accordingly, dysregulation of mRNA …

Polysome-profiling in small tissue samples

…, M Roffé, L Masvidal, GNM Hajj, O Larsson - Nucleic acids …, 2018 - academic.oup.com

[HTML][HTML] Fibrotic extracellular matrix activates a profibrotic positive feedback loop

…, JE Connett, CA Henke, O Larsson… - The Journal of …, 2014 - Am Soc Clin Investig
Pathological remodeling of the extracellular matrix (ECM) by fibroblasts leads to organ
failure. Development of idiopathic pulmonary fibrosis (IPF) is characterized by a progressive …

Bactericidal antisense effects of peptide–PNA conjugates

L Good, SK Awasthi, R Dryselius, O Larsson… - Nature …, 2001 - nature.com

mTORC1-mediated cell proliferation, but not cell growth, controlled by the 4E-BPs

…, BD Fonseca, E Petroulakis, X Wang, O Larsson… - Science, 2010 - science.org
The mammalian target of rapamycin complex 1 (mTORC1) integrates mitogen and nutrient
signals to control cell proliferation and cell size. Hence, mTORC1 is implicated in a large …

[PDF][PDF] mTORC1 controls mitochondrial activity and biogenesis through 4E-BP-dependent translational regulation

…, Y Nouet, A Pause, M Pollak, E Gottlieb, O Larsson… - Cell metabolism, 2013 - cell.com
mRNA translation is thought to be the most energy-consuming process in the cell. Translation

eIF4E phosphorylation promotes tumorigenesis and is associated with prostate cancer progression

L Furic, L Rong, O Larsson… - Proceedings of the …, 2010 - National Acad Sciences
Translational regulation plays a critical role in the control of cell growth and proliferation. A
key player in translational control is eIF4E, the mRNA 5′ cap-binding protein. Aberrant …

mTOR coordinates protein synthesis, mitochondrial activity and proliferation

M Morita, SP Gravel, L Hulea, O Larsson, M Pollak… - Cell cycle, 2015 - Taylor & Francis
Protein synthesis is one of the most energy consuming processes in the cell. The
