FIG. 5.
Increased TFR1 and ferritin protein levels after Grx2 knockdown. (A) Representative Western blot analysis of TfR1 (TfR) and ferritin (FerrH) proteins from mock-transfected (CONT) controls versus 396-transfected (siRNA) cells. Actin is shown as loading control. (B) Band density (integrated density value) is expressed graphically as a percentage ratio of optical density of the TFR1 and ferritin proteins versus actin from three different Western blots. *p < 0.05, siRNA treated compared with controls.
