To read the full abstract: J Clin Endocrinol Metab. 2020; 105(3): dgz255. PMID: 31825489.P450 oxidoreductase deficiency (PORD) is a rare autosomal recessive variant of congenital adrenal hyperplasia (CAH) arising from homozygous or compound heterozygous mutations to the gene encoding the enzyme P450 oxidoreductase (POR ) (1). Patients with PORD have a range of skeletal malformation...

To read the full abstract: Proc Natl Acad Sci U S A 2019;116(27):13670–13679. doi: https://pubmed.ncbi.nlm.nih.gov/31213533/In this paper, Perry et al. studied several animal models to disentangle the mechanism by which leptin suppresses hunger. In rats, the hyperphagia induced by a 48 h fast, or a hypoglycemic hyperinsulinemic clamp, or uncontrolled diabetes, was completely s...

To read the full abstract: Science 2019;365:eaat9351.As in humans, weight gain in mice leads to fatty liver disease, inflammatory adipose tissue, and insulin resistance. The depletion of the microbiota through antibiotic treatment rescued this weight gain. The cohousing of T-Myd88–/– mice transferred the weight gain to wild-type mice. The major feature of the microbiota formed within T-Myd88–/– mice was a reduction in Clostri...

To read the full abstract: Lancet Diabetes and Endocrinology 2018; 6: 114–121Cystic fibrosis (CF)-related diabetes (CFRD) impacts significantly on mortality and quality of life. Impaired glucose metabolism and CFRD are associated with poor weight and height gain and impaired lung function in children and adolescents (1). In that study, height and weight were lower in CF patients wit...

To read the full abstract: Am J Med Genet A. 2016 Nov;170(11):2927-2933The vast majority of proteins that a cell secretes or displays on its surface first enter the endoplasmic reticulum (ER), where they fold and assemble. Only properly assembled proteins advance from the ER to the cell surface. The ER coordinates protein biosynthetic and secretory activities in the cell. Alterations in ER homeost...
