In this study, we
attempt to find out whether chronic low dose 3-Iodothyronamine (an endogenous
metabolite of thyroid hormone) administration could modulate liver de novo
cholesterol synthesis, the same as thyroid hormones. Eighteen male mice were
divided randomly into treatment (n=10) and control (n=8) groups. The experimental
procedure was applied for 7 days during which test group received T1AM whereas
the control group received dimethyl sulfoxide and normal saline. The liver was
analyzed for HMG-CoA reductase concentration and hepatic lipase activity whiles
cholesterol, LDL and HDL concentrations were measured in the blood serum. There
was non-significant decrease in HMG-CoA reductase concentration (224±21.2
versus 187±32.5) in test group compared to control. Interestingly LDL and
cholesterol concentrations exhibited significant decrease in test group versus
the control. There was non-significant decrease in hepatic lipase activity
(771±316 versus 645±317) in test group versus the control. It appears that T1AM
reduced serum LDL and cholesterol just like T3, in contrast, it decreased
liver cholesterol biosynthesis contrary to THs.
