J Clin Invest. 2021 Sep 15;131(18):e144847. doi: 10.1172/JCI144847. PMID: 34237031Brief Summary: This retrospective analysis of clinical, pathologic, and genetic characteristics of n=106 children with differentiated thyroid carcinoma (DCT) showed that fusion oncogene associated papillary thyroid carcinoma (PTC) is more frequent in young children and is associated with larger tumors, extrathyroidal ...

Transdermal estrogen treatment resulted in significantly greater increases in volumetric bone mineral d...

Brief Summary: This experimental study unveiled a new link between the β-cell unfolded protein response and senescence. Deletion of the genes Atf6α or Ire1α in β-cells of non-obese diabetic (NOD) mice prior to insulitis generated a p21-driven early senescence phenotype, which altered the β-cell secretome and promoted protective M2 macrophages recruitment to pancreatic islets. M2 macrophages induced immune surveillance and removal of t...

To read the full abstract: Science 2019;365:eaat9351.As in humans, weight gain in mice leads to fatty liver disease, inflammatory adipose tissue, and insulin resistance. The depletion of the microbiota through antibiotic treatment rescued this weight gain. The cohousing of T-Myd88–/– mice transferred the weight gain to wild-type mice. The major feature of the microbiota formed within T-Myd88–/– mice was a reduction in Clostri...

Transl Psychiatry. 2022; 12(1): 109. PMID: 35296634 https://pubmed.ncbi.nlm.nih.gov/35296634/Brief Summary: This mouse study identified sex and genotype-dependent effects of oral corticosterone on behavioral and physiological outcomes as well as on gene expression and epigenetics in hippocampal subregions.Glucocorticoids exert their effects by binding to glucocorticoid...

Brief Summary: This study significantly advances our understanding of the genetic underpinnings of congenital hypopituitarism (CH) by utilizing whole exome sequencing (WES) in a large cohort of patients from Argentina.CH is a complex and highly heterogeneous disorder that is associated with highly variable clinical phenotypes that range in severity (1). The aetiology of CH may extend beyond monogenic causes, involving oligogenic, polygenic, or multifacto...
