Inhibition of mitochondrial complex I improves glucose metabolism independently of AMPK activation.

Accumulating evidences showed metformin and berberine, well-known glucose-lowering agents, were able to inhibit mitochondrial electron transport chain at complex I. In this study, we aimed to explore the antihyperglycaemic effect of complex I inhibition. Rotenone, amobarbital and gene silence of NDUFA13 were used to inhibit complex I.

[Association of glucose transporter 4 gene polymorphism with hypoxia caused by obstructive sleep apnea syndrome and with related inflammatory factors].

Objective: To investigate the relationship between genetic polymorphisms of glucose transporter 4 (GLUT4) and hypoxia caused by obstructive sleep apnea syndrome (OSAS) as well as with related inflammatory factors.

Methods: Consecutive hypertension patients diagnosed at the People's Hospital of Xinjiang Uygur Autonomous Region were selected from January to December 2010. A total of 859 subjects with possible OSAS base on their histories and physical examination findings udner went the polysomnography and inflammatory factor determination, of whom 616 (72%) were diagnosed with moderate and severe hypoxia with OSAS (case group) and 243 (28%) without hypoxia or OASA (control group).
