Biological Activity
Thyroid Hormone Receptor[1]
The impact of the liver-selective thyromimetic KAT681 (T-0681) is investigated on lipoprotein metabolism. Prolonged treatment with KAT681 increases the hepatic expression of both low-density lipoprotein (LDL) receptor and scavenger receptor class B, type I without affecting cholesteryl ester transfer protein activity. Western blot showing human SR-BI (CLA-1) expression in normal HepG2 cells and in HepG2 cells loaded with AcLDL and subsequently incubated with vehicle or KAT681. SR-BI protein expression is markedly downregulated by incubation with 50 μg/mL AcLDL. This effect can not be reversed by addition of KAT681[1]

Protocol
HepG2 cells are used. At a confluency of 70%, HepG2 cells are incubated with 50 μg/mL of acetylated LDL (AcLDL) for 24 h and subsequently treated with indicated amounts of KAT681 (0.5 μM) in serum-free medium for another 24 h. Cellular protein extraction and Western blot analysis are performed.

Rabbits[1]
Male NZW rabbits are subcutaneously implanted with Alzet osmotic pumps carrying KAT681 (36 nmoles/kg/day) in 1% DMSO/PBS or 1% DMSO/PBS alone as control for the entire duration of the studies. Rabbits are fed a 0.2% cholesterol and 3.5% fat diet or a 2% cholesterol and 5% fat diet. Food consumption is restricted to 100 g/day/animal. At the end of the studies, animals are fasted 5 h before the collection of blood samples, killed by a threefold overdose of pentobarbital, and organ biopsies snap-frozen.
Mice[2]
Male C57/B6 (WT) mice are fed a standard chow diet. After 2 weeks of acclimatization, mice are divided into two groups and subcutaneously implanted with Alzet micro-osmotic pumps carrying KAT681 in PBS (36 nmol/kg/d) or PBS alone as control for 14 days. After 14 days of treatment, animals are fasted for 5 h and anesthetized. Blood samples are taken, mice sacrificed by cervical dislocation, and organ biopsies are snap-frozen. Male SR-BI KO and LDLr KO mice are fed a standard chow diet, and subcutaneously implanted with Alzet micro-osmotic pumps carrying KAT681 in PBS (36 nmol/kg/d) or PBS alone as control. Mice are then fasted for 5 h, blood samples are taken, mice are sacrificed by cervical dislocation, and liver biopsies are snap-frozen.
