3.8. Thyrocyte cell survival and adaptation to chronic endoplasmic reticulum stress due to misfolded thyroglobulin

Y Morishita , O Kabil , KZ Young , AP Kellogg , A Chang , P Arvan

To read the full abstract: J Biol Chem. 2020;295:6876–6887.In this experimental study, Morishita et al. developed a CRISPR/Cas-9 mediated cell model to investigate the molecular effects of thyroglobulin (TG) accumulation in the endoplasmatic reticulum (ER) of thyrocytes, as is observed in the context of dyshormonogenic CH caused by TG gene mutations. TG accumulation in the ER is a result of TG mutations altering t...

A Teumer , L Chaker , S Groeneweg , Y Li , Munno C Di , C Barbieri

To read the full abstract: Nat Commun. 2018;9:4455.Here, the largest genome-wide association study (GWAS) to date on thyroid function and dysfunction, in 72,167 individuals testing 8 million genetic variants, substantially increased the number of loci that are involved in the regulation of thyroid function. It provides functional evidence that two newly identified genes are involved in t...

To read the full abstract: Stem Cell Res Ther. 2018 Nov 21; 9 (1):317Spermatogonial stem cell transplantation (SSCT) could become a fertility restoration tool for childhood cancer survivors. However, the colonization efficiency of transplanted spermatogonial stem cells (SSCs) in animal models is about 12%, and the effectiveness of this procedure needs to be improved before clinical imple...

1.3 Hypothalamic stem cells control ageing speed partly through exosomal miRNAs

Y Zhang , MS Kim , B Jia , J Yan , JP Zuniga-Hertz , C Han , D Cai

To read the full abstract: Nature 2017;548:52-57The central nervous system contributes to ageing. The hypothalamus seems to be particularly important in this process. Recent studies have demonstrated a link between ageing and a decrease of neurogenesis in the hippocampus and the subventricular zone of the lateral ventricle in the brain. Neural stem/progenitor cells (NSC) reside in those regions in ...
