常見(jiàn)問(wèn)題列表
生物活性
Tetrac (Tetraiodothyroacetic acid)，L-甲狀腺素 (T4) 的天然衍生物，是甲狀腺素整合素受體拮抗劑。Tetrac 阻斷 T4 和 3,5,3'-triiodo-L-thyronine (T3) 在整聯(lián)蛋白 αvβ3 上甲狀腺激素的細(xì)胞表面受體處的作用。Tetra 具有抗血管生成和抗腫瘤活性。體外研究

K-RAS
status.
Tetrac (0.1 μM; 30 min) inhibits activation of ERK1/2 in HT-29 and HCT116 cells.
Tetrac (0.1 μM; 24 h) inhibits expression of
CCND1
and
c-Myc
, but promotes expression of
CASP2
and
THBS1
.
Cell Proliferation Assay
| Cell Line: | HT-29 and HCT116 cells |
| Concentration: | 0.01, 0.1, 1 μM |
| Incubation Time: | 0, 2, 4, 6 days |
| Result: | Induced anti-proliferation of K-RAS wild-type colorectal cancer cells. |
Western Blot Analysis
| Cell Line: | HT-29 and HCT116 cells |
| Concentration: | 0.1 μM |
| Incubation Time: | 30 min |
| Result: | Inhibited constitutively activated ERK1/2, and this inhibition can remove by anti-integrin αvβ3 antibody pretreatment. |
體內(nèi)研究
