Journal ArticleDOI
Role of Follistatin in Promoting Adipogenesis in Women
John N. Flanagan,Kristina Linder,Niklas Mejhert,Elisabeth Dungner,Kerstin Wåhlén,Pauline Decaunes,Mikael Rydén,Peyman Björklund,Stefan Arver,Shalender Bhasin,Anne Bouloumié,Peter Arner,Ingrid Dahlman +12 more
TL;DR: Down-regulated WAT expression of follistatin in obesity may counteract adiposity but could, by inhibiting adipogenesis, contribute to hypertrophic obesity (large fat cells) and insulin resistance.
Journal ArticleDOI
Long-term Protective Changes in Adipose Tissue After Gastric Bypass
Johan Hoffstedt,Daniel P. Andersson,Daniel Eriksson Hogling,Jakob Theorell,Erik Näslund,Anders Thorell,Anna Ehrlund,Mikael Rydén,Peter Arner +8 more
TL;DR: RYGB improves long-term insulin sensitivity and adipose phenotypes beyond the control state despite weight regain and postoperative beneficial alterations in adipose function may be involved in the diabetes-protective effect of bariatric surgery.
Journal ArticleDOI
The Q/E27 polymorphism in the beta2-adrenoceptor gene is associated with increased body weight and dyslipoproteinaemia involving triglyceride-rich lipoproteins.
Ewa Ehrenborg,Josefin Skogsberg,G. Ruotolo,Valérie Large,Per Eriksson,Peter Arner,Anders Hamsten +6 more
TL;DR: The Q/E27 polymorphism in the β2‐adrenoceptor gene is associated with increased body weight and dyslipoproteinaemia involving triglyceride‐rich lipoproteins.
Journal ArticleDOI
Effects of treatment with testosterone alone or in combination with estrogen on insulin sensitivity in postmenopausal women.
TL;DR: It is concluded that 3 months of treatment with testosterone undecanoate in postmenopausal women induces insulin resistance and an adverse serum lipid profile but may increase lean body mass.
Journal ArticleDOI
Pancreatic beta-Cell Lipotoxicity Induced by Overexpression of Hormone-Sensitive Lipase.
Maria Sörhede Winzell,Håkan Svensson,Sven Enerbäck,Kim Ravnskjaer,Susanne Mandrup,Victoria Esser,Peter Arner,Marie-Clotilde Alves-Guerra,Bruno Miroux,Frank Sundler,Bo Ahrén,Cecilia Holm +11 more
TL;DR: It is proposed that hormone-sensitive lipase is involved in mediating beta-cell lipotoxicity by providing ligands for peroxisome proliferator-activated receptors and other lipid-activated transcription factors, which in turn alter the expression of critical genes.
