Brief summary: Using a combination of expression studies in human embryos as well as functional studies in zebrafish and genetic sequencing of patient with congenital hypogonadotropic hypogonadism, this study identified a novel role for Jag1/Notch signaling in the development of GnRH neurons.GnRH neurons have a unique characteristic as they start life in the olfactory placode and then migrate into the hypothalamus during embryonic development, thanks to ...

Proc Natl Acad Sci USA 2021 Feb 23;118(8):e2019152118. Abstract: https://pubmed.ncbi.nlm.nih.gov/33597301/In brief: Sox9 is the key transcription factor and master regulator of chondrocyte differentiation during skeletal development. This paper demonstrates that SOX9 also has a key role during postnatal life to maintain open growth plates and healthy articular cartilage by preventi...
