1 Interestingly, the methylxanthine caffeine can abrogate the p53 accumulation induced by certain DNA-damaging agents by an unknown mechanism. Caffeine tumor protein p53 Homo sapiens
2 Caffeine inhibited the accumulation of p53 induced by leptomycin B (LMB), an inhibitor of CRM1, but not N-acetyl-leu-leu-norleucinal, a proteasome inhibitor. Caffeine tumor protein p53 Homo sapiens
3 Furthermore, caffeine also inhibited the accumulation of p53 by a variety of stress-inducing agents in vivo, such as 5-fluorouracil, doxorubicin, mitomycin C, camptothecin and roscovitine. Caffeine tumor protein p53 Homo sapiens
