5.9. MKRN3 inhibits puberty onset via interaction with IGF2BP1 and regulation of hypothalamic plasticity

Brief summary: Using human induced pluripotent stem cells as well as transgenic mouse models, this paper shows that MKRN3 could initiate pubertal onset by regulating hypothalamic development and plasticity.The reactivation of GnRH secretion at puberty is thought to result from a loss in inhibitory input together with an increase in transactivation onto GnRH neurons. The main component of this inhibitory tone was incompletely understood until the discover...

Brief summary: This study summarises the involvement of specific miRNAs in diabetes mellitus, thyroid diseases, osteoporosis, pituitary tumours, Cushing’s disease, adrenal insufficiency and multiple endocrine neoplasia’s. Furthermore, the potential of miRNA as candidates for developing novel diagnostic and therapeutic tools is also discussed.Endocrine disorders are common worldwide and represent a considerable public health problem due to long ...

8.14. Glucose-responsive microneedle patch for closed-loop dual-hormone delivery in mice and pigs

C Yang , T Sheng , W Hou , J Zhang , L Cheng , H Wang , W Liu , S Wang , X Yu , Y Zhang , J Yu , Z Gu

Brief summary: In this experimental study, a transdermal polymeric microneedle (MN) patch for glucose-responsive closed-loop insulin and glucagon delivery was developed. In chemically-induced type 1 diabetes (T1D) mouse and minipig models, this glucose-responsive dual-hormone MN patch demonstrated tight regulation in blood glucose.The interplay between insulin and glucagon is essential for blood glucose regulation in individuals with or without diabetes....

PMID: 34799566.Brief Summary: The authors used RNA-seq, ATAC-seq, and promoter-focused Capture C to characterize the genetic architecture during hypothalamic differentiation. This information provides insights into mechanisms by which noncoding GWAS loci are associated with hypothalamic-regulated traits potentially mediat...

Brief summary: Villanueva-Carmona et al. identified succinate as a mediating metabolite in leptin secretion. Its action is mediated by the succinate receptor SUCNR in adipocytes via the circadian clock in an AMPK/JNK-C/EBPa-dependent manner.Although the regulatory circuits of leptin action on hunger and satiety are well understood, the pathways that mediate acute leptin production in the adipose tissue are less investigated. To investigate how a...

Diabetologia. 2020;63(12):2605–2615. doi: 10.1007/s00125-020-05276-4.Diabetes diagnosed at <6 months of age is often of monogenic origin. However, 10-15% of affected infants do not have a pathogenic variant in one of the 26 known neonatal diabetes genes. In this study, 166 infants diagnosed at <6 months of age without such pathogenic variants showed all the the classic feat...
