GLUT1 levels in androgen-deprived LNCaP cells. GLUT1 protein levels were analyzed by western-blot in LNCaP cells grown in absence of glucose in medium with FBS_chst. LNCaP cells were previously grown 48 h in medium with FBS_chst. An arbitrary value of 1.0 was given to control cells. Glucose concentration was always set at 2 g/L in control cells. Results are expressed as mean ± SEM (n = 3). Beta-actin was employed as internal standard and one representative experiment is shown. **p < 0.01,***p < 0.05.
