Primary hepatocytes were isolated from 12-week-old male Prom1+/+ (WT) or Prom1-/- (KO) mice and serum-starved. (N) Prom1+/+ or Prom1-/- hepatocytes serum-starved for 8 hours were incubated with 2-[3H]deoxyglucose for 10 minutes. Glucose uptake was assessed by calculating the amount of cell-associated radioactivity normalized to the amount of protein (n = 3 mice/group).
