6.14 GATA4 Variants in Individuals With a 46,XY Disorder of Sex Development (DSD) May or May Not Be Associated With Cardiac Defects Depending on Second Hits in Other DSD Genes

To read the full abstract: Front Endocrinol (Lausanne). 2018 Apr 4;9:142Here, Martinez de LaPiscina et.al. investigated gene-gene interactions in 46,XY DSD. GATA4 is known to be associated with 46,XY DSD and has also been described to cause congenital heart defects. The authors characterize 3 individuals with 46,XY DSD, and GATA4 variants; 1 patient with and 2 without congenital heart defects....

3.14. SIRT2 regulates extracellular vesicle-mediated liver-bone communication

L Lin , Z Guo , E He , X Long , D Wang , Y Zhang , W Guo , Q Wei , W He , W Wu , J Li , L Wo , D Hong , J Zheng , M He , Q Zhao

In Brief: These authors studied liver-specific SIRT2 knockout mice to examine how loss of hepatocyte SIRT2 (Sirtuin 2) prevents bone loss in aged mice. Hepatocyte SIRT2 deficiency led to upregulation of Leucine rich α2 glycoprotein (LRG1) in hepatocyte-derived small extracellular vesicles (sEVs) which inhibited osteoclastogenesis in bone marrow.Commentary: Liver-bone communication has been implicated in bone homeostasis. P...

Brief summary: In this experimental study, pancreas-derived mesenchymal stem cells (PMSCs) were implanted into the kidney capsule of mice with streptozotocin (STZ)-induced diabetes. PMSCs led to increased levels of IL-6 in T-helper 1 and T-helper 17 cells, which transiently activated tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ), which in turn decreased levels of interleukin-17. This was associated with exocrine pancreas regeneration and rescue of ...

2.20. Maternal obesity influences placental nutrient transport, inflammatory status, and morphology in human term placenta

P Nogues , E Dos Santos , A Couturier-Tarrade , P Berveiller , L Arnould , E Lamy , S Grassin-Delyle , F Vialard , MN Dieudonne

J Clin Endocrinol Metab. 2021 Mar 25;106(4):e1880–e1896. doi: 10.1210/clinem/dgaa660. PMID: 32936881.By studying placentas from normal weight mothers and obese (non-diabetic) mothers, the authors found that maternal obesity was associated with lower expression of nutrient transporters (such as for glucose and amino acids), surprisingly fewer immune cells, and compromised endocrine func...

PMID: 33571362This report gathered data from two large observational studies (NordiNet International Outcome Study and ANSWER Program) aimed at assessing the incidence of adverse drug reactions (ADRs), serious adverse events (SAEs), and their relation with rhGH dose. The whole study cohort included 37,7...

PLoS One. 2020 Jun 26;15(6):e0234970. doi: 10.1371/journal.pone.0234970.In brief: Metabolite signatures were compared between children with normal weight, obesity, and both obesity and T2DM, by measuring 273 analytes in fasting plasma and a 24-hour urine sample. Twenty-two urine metabolites were uniquely associated with T2DM. Adolescents with T2DM have altered purine nucleoti...

Hum Mol Genet ddac107 (2022)Abstract: https://pubmed.ncbi.nlm.nih.gov/35567544/In Brief: Disproportionate tall stature represents a hallmark feature of Marfan syndrome, although specific mechanisms underlying linear bone overgrowth are unclear. This study used an ex vivo model system to identify dysregulation of TGFβ-binding proteins in the outer perichondrium as causative for the bon...
