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...

5.1. Cartilage-targeted IGF-1 treatment to promote longitudinal bone growth

JC Lui , M Colbert , CSF Cheung , M Ad , A Lee , Z Zhu , KM Barnes , DS Dimitrov , J Baron

Abstract: Mol. Ther. 2019;27:673–680.In brief: The authors developed a fusion protein containing a cartilage-targeting antibody fragment and Insulin-like growth factor 1 (Igf1) and demonstrate that it can stimulate growth plate cartilage at lower and less frequent doses than Igf1. This is a novel approach that paves the way for the development of tissue-specific target...

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...
