Figure 3From: Coupled down-regulation of mTOR and telomerase activity during fluorouracil-induced apoptosis of hepatocarcinoma Cells Inhibition of mTOR activity by 5-Fu. SMMC-7721 cells were treated with or without 5-Fu (62.5 μg/ml) for 36 h. Expression of P-p70S6K protein was detected by Western Blot. Cell lysates were immunoblotted with P-p70S6K Thr 389 antibody.Back to article page
