Novel Leptin-Cardiac TRH pathway responsible for the cardiac alterations in the Hyperleptinemic obesity.

The association between hypertension and obesity-induced cardiac damage is usually accepted. However, no studies have been focused on cardiac alterations in obesity, independently of blood pressure increase. It is well known that Cardiac TRH induces Left Ventricular Hypertrophy (LVH) and fibrosis, and its inhibition prevents the development of hypertrophy.

Cardiovascular and body weight regulation changes in transgenic mice overexpressing thyrotropin-releasing hormone (TRH).

Thyrotropin-releasing hormone (TRH) plays several roles as a hormone/neuropeptide. Diencephalic TRH (dTRH) participates in the regulation of blood pressure in diverse animal models, independently of the thyroid status. The present study aimed to evaluate whether chronic overexpression of TRH in mice affects cardiovascular and metabolic variables.

Short-term doxorubicin cardiotoxic effects: involvement of cardiac Thyrotropin Releasing Hormone system.

Unlabelled: Doxorubicin is an antineoplastic in the anthracycline class widely used for the treatment of several solid tumors and blood cancers. Cardiotoxicity is the major dose-limiting adverse effect of the drug. Chronic and accumulated doxorubicin administration cause myocyte damage and myocardial fibrosis.
