Effect of iodine-containing thyroid hormones on the expression of the early genes c-fos and c-jun in the myocardium of rats under stress

Abstract

The dependence of the expression of the early genes c-fos and c-jun in the myocardium of rats under different-origin stress on the thyroid status of the organism was established. The introduction of merkazolil (intragastrically at a dose of 25 mg/kg for 20 days), leading to the development of experimental hypothyroidism, increases the expression of the studied genes but eliminates the stress-induced increase in their mRNA level. The introduction of small doses of L-thyroxine (intragastrically 1.5-3.0 mg/kg for 28 days) does not affect the expression of c-fos and c-jun in the heart but provides its greater stimulation under the action of all studied stressors.
