To read the full abstract: Cell. 2019;179, 1–17. doi: https://pubmed.ncbi.nlm.nih.gov/31761534/The current study demonstrates that primary cilia, which are present on all adult mesenchymal stem cells including preadipocytes, play a major role in adipogenic differentiation. Using a transgenic mouse model where all preadipocytes were devoid of cilia, they could elegantly show that cilia ...

Abstract: Lancet Diabetes Endocrinol. 2019 Feb;7(2):93–105.In brief: The study reports outcomes of a single-arm 7-year phase 2 extension trial of Asfotase alfa for infants and children with life-threatening hypophosphatasia who received a median of 6·6 years of therapy. The early improvements previously reported were sustained for up to 7 years of treatment.<p class...

To read the full abstract: Int J Obes 2019; 43(2): 384–91Studies regarding brown adipose tissue (BAT) activity in children are scarce due to the difficulties in detecting BAT by imaging and the need for elaborate techniques to measure BAT activity. Here, prepubertal children born small for gestational age (SGA, n=41) and children born appropriate for gestational age (AGA, <...

4.12. Metabolic surgery-induced changes of the growth hormone system relate to improved adipose tissue function

S Gancheva , S Kahl , C Herder , K Strassburger , T Sarabhai , K Pafili , J Szendroedi , M Schlensak , M Roden

Brief Summary: This longitudinal study explored the impact of metabolic surgery on the growth hormone (GH)/IGF-1 axis and its subsequent effects on adipose tissue function. The results suggest that bariatric surgery enhances GH-IGF-1 levels, which are linked to improved adipose tissue function and a reduction in inflammation markers.This study explored how metabolic surgery influences the GH system, and how these changes are related to improvements in ad...

PMID: 35044245Brief Summary: This study combines animal model and patient cohort data on the effect of hyperthyroidism and hypothyroidism at birth on adrenal gland development and function. The data revealed reciprocal effects of neonatal hyper- and hypothyroidism on adrenal development, activity of the adrenal steroidogenic pathway a...

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...
