Metformin alleviates oxidative stress and enhances autophagy in diabetic kidney disease via AMPK/SIRT1-FoxO1 pathway.

Metformin, as the basic pharmacological therapy and the first preventive drug in type 2 diabetes mellitus (T2DM), is proved to have potential protection in diabetic kidney disease (DKD). Here, we established a diabetic rat model induced by high-fat diet and low dose streptozotocin, and high glucose cultured rat mesangial cells (RMCs) pre-treated with metformin or transfected with AMPK, SIRT1 and FoxO1 small interfering RNA, and detected oxidative stress and autophagy related factors to explore the molecular mechanisms of metformin on DKD via adenosine monophosphate-activated protein kinase (AMPK)/silent mating type information regulation 2 homolog-1 (sirtuin-1, SIRT1)-Forkhead box protein O1 (FoxO1) pathway. We found that metformin effectively alleviated the disorders of glycolipid metabolism, renal function injury in diabetic rats, and relieved oxidative stress, enhanced autophagy and slowed down abnormal cell proliferation in high glucose cultured RMCs through AMPK/SIRT1-FoxO1 pathway, indicating the protective role of metformin against the pathological process of DKD.

Dehydrocostus Lactone Suppresses Proliferation of Human Chronic Myeloid Leukemia Cells Through Bcr/Abl-JAK/STAT Signaling Pathways.

This study evaluates the anticancer effects of dehydrocostus lactone, a plant-derived sesquiterpene lactone, on human chronic myeloid leukemia cells. Dehydrocostus lactone significantly inhibits cell proliferation by inducing cells to undergo cell cycle arrest, apoptosis, and differentiation. Dehydrocostus lactone suppresses the expression of cyclin B1, cyclin A, cyclin E, cyclin-dependent kinase 2 (CDK2), and cyclin-dependent kinase 1 (CDK1) and increases p21 expression, resulting in S-G2/M phase arrest in K562 cells.

The key locus of common response inhibition network for no-go and stop signals.

Response inhibition is one of the highest evolved executive functions of human beings. Previous studies revealed a wide variety of brain regions related to response inhibition, although some of them may not be directly related to inhibition but to task-specific effects or noninhibitory cognitive functions such as attention, response competition, or error detection. Here, we conducted event-related functional magnetic resonance imaging studies in which all subjects performed both stop-signal and go/no-go tasks in order to explore key neural correlates within the response inhibition network irrelevant to task designs and other cognitive processes.
