描述

一般說明

Thyroxine (T₄) is a tetraiodo derivative of the p-hydroxyphenyl ether of tyrosine, which functions as growth factors or cell growth inhibitors. T₄ is used to treat hypothyroidism and thyroid carcinoma. It regulates energy metabolism.

應用

L-Thyroxine has been used to investigate its role in colorectal cancer cell lines HCT 116 (APC wild type) and HT-29 (APC mutant). It has also been used to evaluate its effects on pro-inflammatory tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), angiogenic vascular endothelial growth factor (VEGF), leukocyte adhesion, intercellular adhesion molecule 1 (ICAM-1) and E-selectin in human umbilical vein endothelial cells (HUVECs).

生化／生理作用

L甲状腺素 (T₄) 和三碘代-L-甲状腺原氨酸 (T₃) 为含碘激素，由甲状腺卵泡细胞中的甲状腺球蛋白制备。这些激素对代谢率的刺激以及对生长发展的调节似乎归因于它们对 DNA 转录的作用，进而影响蛋白质的合成。

準備報告

For long term storage, keep stock solutions at -20° in working aliquots and avoid repeated freeze/thaw cycles. Solutions stored at 2-8 °C are stable for up to 30 days.

重構

To prepare 20 μg/ml stock solution, dissolve in 50 ml sterile culture medium per mg thyroxine.
