Novel ABCA1 peptide agonists with antidiabetic action
Publication date: Available online 2 October 2018Source: Molecular and Cellular EndocrinologyAuthor(s): Salman Azhar, Stefanie Bittner, Jie Hu, Wen-Jun Shen, Yuan Cortez, Xiao Hao, Han Lu, Jens O. Lagerstedt, Fredric B. Kraemer, Jan O. JohanssonAbstractPreviously, apoE-derived ABCA1 agonist peptides have been shown to possess anti-atherosclerotic and possibly antidiabetic properties. Here we assessed the in vitro and in vivo actions of a second generation of ABCA1 peptide agonists, CS6253 and T6991-2, on glucose homeostasis. The results show that these two peptides improve glucose tolerance in a prediabetic diet-induced ob...

Hyperlipidemia-induced hepassocin in the liver contributes to insulin resistance in skeletal muscle
In conclusion, we elucidated that ER stress induced by palmitate could increase the expression of HPS in hepatocytes and further contribute to the development of insulin resistance in skeletal muscle via EGFR/JNK-mediated pathway. Taken together, we suggest that HPS could be a therapeutic target for obesity-linked insulin resistance. Graphical abstract
