Nat Med. 2021 Dec;27(12):2104-2107. https://pubmed.ncbi.nlm.nih.gov/34887578/Brief Summary: This study used single-cell transcriptomic analyses to generate a cell atlas of the human fetal and neonatal small intestine. Notably, the authors identified a subset of fetal enteroendocrine K/L cells (named FIKL) that express high levels of insulin and other beta cell genes.T...

15.12 TAp63 contributes to sexual dimorphism in POMC neuron functions and energy homeostasis

C Wang , Y He , P Xu , Y Yang , K Saito , Y Xia , X Yan , A Hinton Jr , C Yan , H Ding

To read the full abstract: Nature Communications 2018;9:1544Obesity prevalence is generally higher in women than in men, and there is also a sex difference in body fat distribution. Sex differences in obesity can be explained in part by the influence of gonadal steroids on body composition and appetite; however, behavioural, and socio-cultural factors may also play a role. Here is th...

15.14 Epigenetic modulation of Fgf21 in the perinatal mouse liver ameliorates diet-induced obesity in adulthood

X Yuan , K Tsujimoto , K Hashimoto , K Kawahori , N Hanzawa , M Hamaguchi , T Seki , M Nawa , T Ehara , Y Kitamura

To read the full abstract: Nature Communications 2018;9:636We know that good nutrition early in life has profound and long-lasting effects on body weight in later life. Malnutrition during pregnancy or infant formula feeding may be stored on the offspring genome as epigenetic memory and persist into adulthood, thereby influencing the susceptibility to metabolic diseases, such as obes...

15.16. Causality-enriched epigenetic age uncouples damage and adaptation

K Ying , H Liu , AE Tarkhov , MC Sadler , AT Lu , M Moqri , S Horvath , Z Kutalik , X Shen , VN. Gladyshev

In Brief: The authors harness large-scale genetic and DNA methylation datasets in an epigenome-wide Mendelian randomization approach, to identify CpG sites that appear to be causally related to aging-related traits. These sites are collated to produce 2 epigenetic clocks: DamAge has adverse impacts on age-related outcomes, including mortality. AdaptAge appears to confer beneficial adaptations.Steve Horvath and others originally described various epigenet...

4.3. AAV-mediated gene therapy produces fertile offspring in the Lhcgr-deficient mouse model of Leydig cell failure

K Xia , F Wang , X Lai , L Dong , P Luo , S Zhang , C Yang , H Chen , Y Ma , W Huang , W Ou , Y Li , X Feng , B Yang , C Liu , Z Lei , X Tu , Q Ke , FF Mao , C Deng , AP Xiang

Brief summary: In this in vivo study, Xia et al. demonstrate that AAV-mediated gene therapy recovers testosterone levels, restarts sexual development, restores spermatogenesis, and produces fertile offspring in a mouse model of Leydig cell failure (LCF).A null mutation in the gene encoding luteinizing hormone/choriogonadotrophin receptor (Lhcgr) causes a hereditary LCF in mice which is characterized by a reduction in testosterone levels...

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...
