To read the full abstract: Science 2018;360:1087-1092During the Cardiovascular Risk Survey in western China, a Kazakh family with inherited low levels of LDL-C was identified. The Kazakhs are mainly descendent from the Turkic and medieval Mongol peoples, they live in isolated regions and usually marry within their own ethnic group. They exhibit often unique differences in single nucleotide vari...

11.2. Mutations in the leptin-melanocortin pathway and weight loss after bariatric surgery: a systematic review and meta-analysis

N Zhang , H Wang , S Ran , Z Wang , B Zhou , S Wang , Z Li , B Liu , Y Nie , Y Huang , H Meng

Brief Summary: This review evaluated the impact of gene mutations in the leptin-melanocortin pathway on short- and long-term outcomes after bariatric surgery, which is still the most effective treatment for severe obesity. This topic is of high clinical relevance, since such mutations play an important role in hunger regulation and energy homeostasis [1, 2] and may therefore confer weight regain after bariatric surgery [3]. To date there have been few publications, often with ...

Brief summary: In this experimental study, pancreas-derived mesenchymal stem cells (PMSCs) were implanted into the kidney capsule of mice with streptozotocin (STZ)-induced diabetes. PMSCs led to increased levels of IL-6 in T-helper 1 and T-helper 17 cells, which transiently activated tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ), which in turn decreased levels of interleukin-17. This was associated with exocrine pancreas regeneration and rescue of ...

Nature 2019;567:187–193.URL https://doi.org/10.1038/s41586-019-0984-ySummary: Novel diagnostic and prognostic biomarkers in the blood that can predict early fatty liver disease were identified, using a proteomic and lipidomic-wide systems genetic approach in 107 genetically distinct mouse strains. In addition, the novel lipid-regulatory protein, PSMD9, was identified as...

Brief Summary: Artemisinins, compounds known for their antimalarial properties, suppress ovarian androgen synthesis by promoting degradation of cytochrome P450 11A1 (CYP11A1). Hence, they are a promising new approach for preventing and treating PCOS.Comment: Polycystic ovary syndrome (PCOS), characterized by hyperandrogenism, chronic anovulation, and insulin resistance, is one of the most common reproductive endocrinopathies, affecting ~8-18% of reproduc...
