Figure 6.

Chronic glucolipotoxic conditions in vitro reduce intracellular insulin content. Rat islets were cultured under normal conditions (control) or with 16.7mM glucose and 500 μM palmitate for 72 h (GL). Post 72 h, islets were treated with 2 mM glucose (LG) or 11 mM glucose (HG) for 2 h. Islets were washed, lysed and islet insulin content was measured. Data is expressed as mean±SEM and statistical analysis was performed using the unpaired Student’s t-test. (*P<0.05, **P<0.01 and ***P<0.001, n=4).
