Mechanism of Action of the Thyroid Hormone on the Heart
SUMMARY The foliowing cardiac effects may be attributed to thyroxin: 1-Thyroxin augments all anaerobic processes in the body includ::ng the heart, and decreases the glycogen content of the heart ( 1, 2, 5, 27). The resistance of the heart to anoxia is increased in hyperthyroidism ( 25). 2- Thyroxin influences the cardiac weight and prevents cardiac atrophy (3, 8, 10, 11, 19, 20, 21, 30...
متن کاملMechanism of thyroid hormone action.
Thyroid hormone (triiodothyronine [T3]) regulates gene expression by binding to high-affinity nuclear receptors. Thyroid hormone receptors (TRs) recognize specific response element sequences in the promoters of T3-target genes and activate or repress transcription in response to hormone. In this paper, we review the TR proteins and thyroid hormone response elements (TREs) to which they bind, th...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولHypertensive cardiovascular disease induced by desoxycorticosterone in hypophysectomized rats bearing pituitary autotransplants.
The responsiveness of hypophyseetomized female rats bearing pituitary autotransplants to chronic, low dosage treatment with desoxycorticosterone acetate was compared with that of intact females. Intact animals reacted rapidly, developed malignant hypertension, and died within 10 weeks. By contrast hypophysectomized autograft-bearing rats developed hypertension more slowly, and the majority of t...
متن کاملRamadan Fasting and Thyroid Hormone Levels in Women with Hypothyroidism
Introduction: According to some studies, Ramadan fasting causes minimal changes in the levels of thyroid hormones. The present study aimed to evaluate the impact of Ramadan fasting on the levels of thyroid hormones in fasting women with hypothyroidism and levothyroxine intake. Methods: Serum levels of free thyroxine (T4) and thyroid-stimulating hormone (TSH) we...
