描述 | Liothyronine Sodium is the sodium salt form of liothyronine, a synthetic form of the levorotatory isomer of the naturally occurring thyroid hormone triiodothyronine (T3). Liothyronine (Sodium) is an active form of thyroid hormone, which binds to β1 thyroid hormone receptor (TRβ1), and activates its activity. Liothyronine (T3, 100 nM) stimulates the proliferation of hepatocarcinema cells in which TRβ1 is overexpressed[3]. High T(3) (triiodothyronine) levels induce a low TRalpha1:TRalpha2 ratio which could protect the cell from excessive T(3)-induced gene expression[4]. Expression of a mutant receptor with impaired triiodothyronine (T(3)) binding and dominant negative activity affected cerebellar development and motor performance. TRs are also involved in adult brain function. TRalpha1 deletion, or expression of a dominant negative mutant receptor, induces consistent behavioral changes in adult mice, leading to severe anxiety and morphological changes in the hippocampus[5]. |

溶解方案 |
DMSO: 4 mg/mL(5.94 mM),配合低频超声,并水浴加热至45℃助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO 0.1 M NaOH: 10 mg/mL(14.86 mM),配合低频超声,并调节pH至11 以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂: ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
