To read the full abstract: J Clin Invest 2018;128:960-969Mouse models for PWS are urgently needed to facilitate drug development for treatment of hyperphagia and obesity in PWS patients. Here, the authors set out to create a mouse model that better recapitulates human PWS; they chose Snord116 as the target. Snord116 comprises a cluster of noncoding RNAs (ncRNAs) on paternal chromosome 15q11.2. Deletio...

To read the full abstract: N Engl J Med 2018;378:1987-1998FGF-23 is the primary regulator of phosphate homeostasis and acts by inhibiting phosphate reabsorption in the kidney (1). Loss-of-function mutations in the gene encoding phosphate-regulating endopeptidase homolog X-linked (PHEX) results in excess circulating FGF-23, which impairs renal phosphate reabsorption causing hypophosphatemia...

As for most skeletal dysplasias, current treatment options remain symptomatic due to the lack in causal therapeutic measures. In the actua...

To read the full abstract: Kidney Int 2017;92:599-611Klotho was originally identified as a senescence-related protein because mice carrying hypomorphic Klotho alleles (kl/kl) develop premature aging with low bone turnover and osteoporosis. Primary function of Klotho is to form a specific receptor complex with fibroblast growth factor (FGF) receptor 1 (FGFR1) through which it mediates the bio...

To read the full abstract: J Pediatr Endocrinol Metab. 2017;30:869-877Several previous studies had focused on the early risk of metabolic syndrome or its components in survivors of childhood acute lymphoblastic leukaemia (ALL), while fewer data are available on pubertal development in these subjects. The merit of this study was to carefully investigate growth and pubertal development in a large ...

To read the full abstract: Pediatr Rheumatol Online J. 2017Aug 22;15(1):68This large prospective study analysed growth in children with JIA during a 3-year period from diagnosis. Interesting findings emerge: the heights and weights of these patients, clearly compromised in historical cohorts, appeared nearly normal. Increased risk of growth impairment was noted in patients with systemic arthr...
