常见问题列表
生物活性
Clitocine 是一种来源于蘑菇的腺苷核苷类似物，是一种有效的通读剂 (readthrough)。Clitocine 作为一种无义突变 (nonsense mutations) 的抑制剂，可诱导携带 p53 无义突变等位基因的细胞产生 p53 蛋白。Clitocine 可通过靶向 Mcl-1 诱导多药耐药肿瘤细胞凋亡。具有抗癌活性。体外研究
Clitocine incorporation into mRNA is required for premature stop codon readthrough activity, and the presence of clitocine at the third position of a premature stop codon is sufficient to promote robust readthrough.
Clitocine (0-0.8 μM; 24 hours) enhances TRAIL-lethality in in LS411N and SW620 cells. Clitocine (0.2μM; 36 hours) significantly potentiates TRAIL-mediated apoptosis.
体内研究
Citocine (0.3-3 mg/kg; s.c.; five times per week)-induced p53 inhibits CAOV-33 p53-UAA136 tumor growth in a xenograft model.
| Animal Model: | nu/nu mice (CAOV-3p53-UAA136 xenograft tumors) |
| Dosage: | 0.3, 3 mg/kg (or 20 mg/kg once per week) |
| Administration: | S.c.; five times per week |
| Result: | CAOV-33 p53-UAA136 tumor growth was inhibited. |
