12.3. NIPA2 regulates osteoblast function by modulating mitophagy in type 2 diabetes osteoporosis

W Zhao , W Zhang , H Ma , M Yang

To read the full abstract: Sci Rep. 2020;10(1):3078. doi: 10.1038/s41598-020-59743-4Short summary: This study describes a specific mechanism of reduced bone formation secondary to hyperglycaemia. In hyperglycaemic states, advanced glycation end products (AGEs) downregulate the highly selective magnesium transporter expression of NIPA2 in osteoblasts. This results in ma...

To read the full abstract: PLoS Med. 2019 Oct 1;16(10):e1002926. doi: 10.1371/journal.pmed.1002926.The authors analysed a huge dataset from the Chinese national programme of preconception health checks, which include measurements of fasting plasma glucose. Overall, 13.15% (n =847,737) had impaired fasting glucose and 1.18% (n =76,297 women) had diabetes, of whom only...

2.12. Maternal obesity impairs skeletal development in adult offspring

JR Chen , OP Lazarenko , H Zhao , AW Alund , K Shankar

To read the full abstract: J Endocrinol. 2018 Jul 26.This study, using a mouse model, investigated the effects of high fat diet-induced maternal obesity on both fetal and adult offspring skeletal development.Maternal nutrition appears to influence epigenetic alterations in the offspring and to program gene expression in key metabolic pathways, such as fatty acids a...

TJ Dening , P Joyce , M Kovalainen , H Gustafsson , CA Prestidge

To read the full abstract: Pharm Res. 2018 Dec 5;36(1):21.Smectite purified from bentonite clay, and laponite SD-LAP, a synthetic Smectite were fed to rodents on a high-fat diet. Over a two-week period both the engineered clay and orlistat had weight loss effects.The unanticipated discovery that clay has a unique ability to “soak up” fat droplets in the g...

7.1 Trithorax dependent changes in chromatin landscape at enhancer and promoter regions drive female puberty

CA Toro , H Wright , CF Aylwin , SR Ojeda , A Lomniczi

To read the full abstract: Nat Commun. 2018 Jan 4;9(1):57The hypothalamic-pituitary-gonadal axis controls the onset of puberty and the acquisition of the reproductive function. A subset of neurons in the anterior hypothalamus secretes gonadotropin-releasing hormone (GnRH) which, through its pattern of release controls all aspects of reproduction throughout life. The secretory activity of GnR...

9.5. A synaptic amplifier of hunger for regaining body weight in the hypothalamus

K Grzelka , H Wilhelms , S Dodt , ML Dreisow , JC Madara , SJ Walker , C Wu , D Wang , BB Lowell , H Fenselau

Brief summary: Grzelka et al. identified a hypothalamic circuit that regulates regain of body weight after weight loss.Body weight is one of the most regulated variables of our body, which is most likely due to the evolutionary history of times when access to food was scarce and volatile. Weight loss triggers a strong counterregulatory response. It increases the hunger drive and greatly increases the reward value of food, making it more difficul...
