• systolic and diastolic blood pressures are lower 3 weeks following tamoxifen induction
• however, heart rate is not affected
• in vascular smooth muscle cells (VSMC), potassium currents are higher than in control VSMCs under basal conditions and with the K(ATP) channel opener, pinacidil, indicating enhanced K(ATP) channel currents
• contraction of mesenteric arteries in response to phenylephrine is shifted about 10-fold to higher phenylephrine concentration compared to control arteries , with an even greater relative shift in the presence of pinacidil, indicating reduced contractility of blood vessels
• however, following constriction by high phenylephrine concentration, subsequent K(ATP)-independent relaxation in response to sodium nitroprusside is not different

cardiovascular system
• arterial wall remodeling in response to Angiotensin II treatment is absent
• cardiac hypertrophy, as assessed by the heart to body weight ratio, is significantly reduced in mice treated with both tamoxifen and Angiotensin II
• Angiotensin II or N-nitro-l-arginine (L-NAME) treatment do not increase blood pressure in tamoxifen treated mice
• tamoxifen treatment starting 10 days after the beginning of Angiotensin II treatment is able to reverse Angiotensin II induced hypertension
• mice treated with deoxycorticosterone acetate plus NaCl are not completely protected from induced hypertension and are resistant to the blood pressure-lowering effects of the subsequent treatment with an Angiotensin II type 1 receptor antagonist
• the amplitude of Angiotensin II induced contractions was much lower in the ex vivo aortic rings, from tamoxifen treated mice
• in tamoxifen treated mice the in vivo response to Angiotensin II is reduced
