Ann Endocrinol (Paris). 2020 Jun;81(2–3):83–88. doi: 10.1016/j.ando.2020.04.004. PMID: 32340851This short review summarises the history and current knowledge of molecular genetic aspects of the human gonadal differentiation toward ovary.Major scientific milestones on the topic are described. It is interesting to learn on what grounds it was common doctri...

PMID: 30941101.It has known that severe traumatic brain injury (TBI) can cause permanent pituitary dysfunction with variable rates, but what about mild TBI?Briet et al. studied 109 children with a traumatic brain injury and Glasgow co...

Haploinsufficiency is a typical mechanism in autosomal dominant disorders. Rare mutations in Sim1 or Mc4r are models of haploinsufficiency causing severe early-onset obesity with hyperphagia...

Brief Summary: This study examined the pulsatile secretion of TSH and its regulatory role in thyroid hormone (TH) synthesis in mice. Using a novel ultra-sensitive ELISA for mouse TSH, it shows that TSH pulsatility plays a critical role in regulating thyroid function.In addition to mapping the normal TSH secretion pattern in healthy mice, and the secretion pattern in a mouse model of disease (mouse made hypothyroid by an iodine-deficient diet enriched wit...

Nat Commun. 2021 May 11;12(1):2677. doi: 10.1038/s41467-021-22859-w. PMID: 33976139This work generated an integrated single nucleus multi-omics resource to elucidate the epigenetic mechanisms that regulate transcriptional networks in the murine pituitary. The authors identified epigenetically defined cell type composition, cell type-specific and sex-specific differences in transcription...

To read the full abstract: J Clin Endocrinol Metab, March 2020, 105(3):e70–e84A cohort of 21 adult males (aged 19 to 89 years) harboring hemizygous pathogenic IGSF1 gene mutations underwent anthropometry, endocrine testing, testis ultrasonography, and body composition assessment to define the pathophysiological role of IGSF1 in influencing GH secretion. In addition, two lines of Igsf1 -deficient male mice were use...

Brief Summary: This multicenter, international, retrospective study evaluated fertility potential and gonadal function in 326 adolescent and young adult cancer survivors. Risk factors for impairment included hematopoietic stem cell transplantation (HCT) conditioning regimen (myeloablative conditioning, MAC vs reduced-intensity conditioning, RIC).The prevalence of gonadal hormone failure in females was 55.3% (defined as FSH >30 mIU/mL with an estradio...
