BL Freire , TK Homma , MFA Funari , AM Lerario , GA Vasques , AC Malaquias , IJP Arnhold , AAL Jorge

To read the full abstract: J Clin Endocrinol Metab. 2019;104:2023–2030.A child born with birth weight and/or birth length less than 2 SDS below the mean for gestational age is defined as SGA [1]. This definition implies that rather than a specific diagnostic group, SGA children are a heterogenous population with different etiologies, growth patterns and metabolic outcomes. Most SGA ...

12.10. Delivery of low-density lipoprotein from endocytic carriers to mitochondria supports steroidogenesis

YX Zhou , J Wei , G Deng , A Hu , PY Sun , X Zhao , BL Song , J Luo

Brief summary: Genome-wide small hairpin RNA screening revealed a specialized role for the protein phospholipase D6 (PLD6) located at and highly expressed in the outer mitochondrial membrane of cells in steroidogenic organs. Here PLD6 promotes the entrance of LDL/LDLR complex into the mitochondria where LDL-carried cholesterol is released for steroid hormone biosynthesis.Thereby the mitochondrial redox-sensitive CISD2 protein was found to support the trafficking of the LDL/LDL...

Brief summary: This study investigates the effect of long-acting synthetic glucocorticoids on circadian rhythmicity and hippocampal functionGlucocorticoids exert their effects by binding to glucocorticoid receptors (GRs), which regulate up to ~20% of the genome via both direct (by binding to glucocorticoid responsive elements in promoter regions) and indirect mechanisms (by interacting with bound transcription factors and epigenetic modifiers) (1...

Nature 2019;567:187–193.URL https://doi.org/10.1038/s41586-019-0984-ySummary: Novel diagnostic and prognostic biomarkers in the blood that can predict early fatty liver disease were identified, using a proteomic and lipidomic-wide systems genetic approach in 107 genetically distinct mouse strains. In addition, the novel lipid-regulatory protein, PSMD9, was identified as...

To read the full abstract: J Pediatr. 2019 Dec;215:192–198.Identifying the diagnosis in children with syndromic short stature and those with recognized genetic growth disorders is often challenging, as they may share many clinical features (1)(2). The candidate gene approach has many limitations in unveiling the genetic cause. Therefore, whole exome sequencing (WES) has been proposed to improve the diagnostic rate in children with short sta...
