Application

Telmisartan has been used as an AT1 receptor antagonist to study its effects on mouse models of myocardial infarction. This study reported that telmisartan inhibited the CCN1 upregulation and reduced CCN2 levels atrial cardiomyocytes. Telmisartan has also been used to evaluate its effect on the expression of CCN1 in kidney cortex of mice subjected to myocardial infarction. Furthermore, telmisartan has been used to test its efficacy against tumor growth in mouse models of colorectal cancer.

Biochem/physiol Actions

The Journal of pharmacology and experimental therapeutics, 302(3), 1089-1095 (2002-08-17)
In vitro studies have shown that telmisartan is an insurmountable angiotensin II subtype-1 (AT1) receptor antagonist. Herein, the molecular basis of this insurmountable antagonism has been investigated in vitro, and the effect of telmisartan has been compared in vivo with

Folia histochemica et cytobiologica, 50(1), 99-103 (2012-04-26)
Previous studies have reported the upregulation of CCN proteins early after acute heart injury. The aim of the present work was to evaluate the expression of the CCN1 and CCN2 proteins and their regulation by angiotensin II in the atrial
