8.18. The association of accelerated early growth, timing of puberty, and metabolic consequences in children

YH Jee , S Jumani , V Mericq

Brief Summary: The mechanism by which suboptimal intrauterine growth and low birth weight for gestational age may lead to postnatal metabolic risks has not been well established. This narrative review summarizes recent studies on the association between early infant growth, timing of puberty, and metabolic risks, thus expanding our knowledge of the underlying pathophysiology.Comment: Early compensatory infantile growth in children born small for gestatio...

5.15. mir-374-5p, mir-379-5p, and mir-503-5p Regulate Proliferation and Hypertrophic Differentiation of Growth Plate Chondrocytes in Male Rats

YH Jee , J Wang , S Yue , M Jennings , SJ Clokie , O Nilsson , JC Lui , J Baron

Abstract: Endocrinology. 2018 Mar 1;159(3):1469–1478.In brief: In this article, a combination of microdissection, miroRNA profiling and transfection studies identify 3 microRNAs that are highly expressed in the proliferative zone and appear to be down-stream mediators of PTHrP signaling in the growth plate.Comment: In the growth plate, P...

3.13. Loss-of-function variant in SPIN4 causes an X-linked overgrowth syndrome

JC Lui , J Wagner , E Zhou , L Dong , KM Barnes , YH Jee , J Baron

In Brief: These authors identify a frameshift truncating variant in the gene SPIN4 (Spindlin member 4) in a patient with skeletal overgrowth, hepatosplenomegaly and macrocephaly. Using state-of-the-art mouse models and histone peptide arrays, they delineate the underlying pathogenic mechanism and show that SPIN4 positively regulates Wnt signalling by functioning as an epigenetic reader.Commentary: Generalized overgrowth disorders are ch...

5.13. Differential aging of growth plate cartilage underlies differences in bone length and thus helps determine skeletal proportions

JC Lui , YH Jee , P Garrison , JR Iben , S Yue , M Ad , Q Nguyen , B Kikani , Y Wakabayashi , J Baron

Abstract: PLoS Biol. 2018 Jul 23;16(7):e2005263.In brief: In this article, Lui et al, make important observations related to the fundamental limits of longitudinal bone growth implicating the growth plate senescence program as a major regulator of bone size.Comment: A person’s right and left arms almost always grow to the same length, bu...

5.5 Aggrecan Mutations in Nonfamilial Short Stature and Short Stature Without Accelerated Skeletal Maturation

C Tatsi , A Gkourogianni , K Mohnike , D DeArment , S Witchel , AC Andrade , TC Markello , J Baron , O Nilsson , YH Jee

To read the full abstract: J Endocr Soc 2017;1:1006-1011Besides its structural role in the extracellular matrix, aggrecan orchestrates a plethora of key mechanisms in endochondral ossification, such as embryonic morphogen distribution, regular indian hedgehog (IHH) / Sox9 expression and columnar chondrocyte orientation. Thus, homozygous loss-of-function mutations in the ACAN gene, encoding...
