EMBO Rep. 2020;21:e50612. doi: 10.15252/embr.202050612.This zebrafish study identified and molecularly characterized adult transcriptionally different thyrocyte subpopulations even within the same follicle.It is well established that within a thyroid gland, follicles are heterogenous concerning functional activity. More active follicles are characterized by a high co...

Matrix Biol. 2020 Aug;90:40–60 Abstract: https://pubmed.ncbi.nlm.nih.gov/32173581/In brief: Mutations in 3-hydroxylation complex genes CRTAP and P3H1 cause osteogenesis imperfecta type VII and VIII, respectively. However, the pathogenic mechanism by which these mutations cause disease remains unclear. This study points to a defective chaperone role of the 3-h...

To read the full abstract: Thyroid. 2019;29:480–492.The thyroid axis is particularly responsive to critical illness. Adaptation processes of the thyroid axis to critical illness and prolonged fasting are well described as non-thyroidal illness syndrome. Non-thyroidal illness is mainly explained by two mechanisms: 1) peripheral inactivation of T4 to rT3 by decreased type-1 deiodinase...

Brief summary: In recent years, generation of human organoids of different tissues from human embryonic stem cells have been realized, e.g. intestine, liver, and lung among others. In contrast, so far all attempts to generate fully mature and functional human thyroid follicular cells from stem cells was not successful. Romitti et al. present for the first time successful generation of transplantable and functional human thyroid organoids derived from human embryonic s...

Cell Rep. 2021 Apr 13;35(2):108981. doi: 10.1016/j.celrep.2021.108981. PMID: 33852861.Mutations in the promotor region of the insulin gene are associated with a subtype of neonatal diabetes mellitus (NDM). These mutations lead to abnormal transcription of the insulin gene and do so by deleting the C1 and E1 cis regulatory elements, or three different single base-pair substitutions in ...

BMJ. 2021 Feb 3;372:n37. doi: 10.1136/bmj.n37. PMID: 33536184This observational cohort study used data from the French administrative healthcare database during 2007–2015 to assess the risk of meningioma development related to treatment with cyproterone acetate. The cohort comprised 253,777 participants, of whom 54% had high exposure to cyproterone acetate, and 45% had low exposure.<p cla...
