Decrease in expression of LAT1 and 4F2hc proteins by treatment of THADA siRNA (siTHADA). A Expression of THADA (190 kDa), LAT1 (40 kDa), 4F2hc (80 kDa), and β-actin (45 kDa) in KB cells. The cells were treated with siTHADA or negative control siRNA (siNC) for 48 h, and then the lysate samples were prepared. Western blotting of the samples (15 μg/lane) was performed. Typical images of the blotting were shown. B Expression levels of THADA, LAT1, and 4F2hc were normalized by corresponding β-actin expression, and the quantitative data were shown. n = 8–9. **P < 0.01 versus siNC
