生物活性

Tetrac (Tetraiodothyroacetic acid), a derivative of L-thyroxine (T4), is a thyrointegrin receptor antagonist. Tetrac blocks the actions of T4 and 3,5,3'-triiodo-L-thyronine (T3) at the cell surface receptor for thyroid hormone on integrin αvβ3. Tetra has anti-angiogenic and anti-tumor activities.

体外研究

Tetrac (0.01-1 μM; 2-6 d) induces anti-proliferation in HT-29 and HCT116 cells with different 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.
体内研究

Tetrac (35 μg; p.o. for 40 days) inhibits tumor inoculation, growth and integrin expression in mice.

Animal Model: Wild-type male Balb/C mice aged 8 weeks are inoculated with 102B16F10 or B16LS9 cells
Dosage: 35 μg per day
Administration: P.o. (added to the drinking water) daily for 40 days
Result: Delayed the onset of ocular melanoma.
Reduced the S-100 and integrin staining level in the B16F10 mice model.
