Brief summary: In this cross-sectional study, 11-oxygenated androgens were measured in morning serum samples from 290 healthy adults (125 men, age 22–95 years; 165 women, age 21–91 years) by LC–MSMS (liquid chromatography, tandem mass spectrometry) to generate normative values across the lifespan. In a subset of volunteers (n=83), additional measurements were performed in saliva to assess diurnal and menstrual cycle-dependent variation. In general, it w...

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...

Proc Natl Acad Sci USA. 2020 Jun 16;117(24):13680–13688. 10.1073/pnas.1921676117. PMID: 32493750.On the search for a genetic cause for 46,XX virilization due to testicular (TDSD) or ovotesticular DSD (OTDSD), 78 individuals were studied by whole exome sequencing. In 7 cases, heterozygous de novo variants were found in the 4th zinc finger (ZF4) of the Wilms tumor 1 gene (<em...
