To read the full abstract: Nat Genet. 2018 Mar;50(3):432-442Maternal obesity is associated with poor outcomes across the reproductive spectrum including infertility, increased time to pregnancy, early pregnancy loss, congenital abnormalities and neonatal complications. Adverse effects are detectable as early as the oocyte and preimplantation embryo stage, and that these early effects may cont...

In Brief: The study established a novel rat model with a clinically relevant PLS3 mutation, which replicates the osteoporotic phenotype of early-onset PLS3-related osteoporosis. The findings suggest that treatment with alendronate or teriparatide improves bone mass and microarchitecture, suggesting their potential as effective treatments for early-onset osteoporosis caused by PLS3 mutations.Commentary: This study is an essentia...

J Bone Miner Res. 2022 Feb;37(2):179-184.Abstract: https://pubmed-ncbi-nlm-nih-gov/34464000/In Brief: Fibroblast growth factor 23 (FGF23) and parathyroid hormone (PTH) both negatively regulate serum phosphate by increasing renal phosphate excretion. The clinical observation that both PTH and FGF23 are needed for adequate renal phosphate handling is confirmed in this experimental patient stu...
