Han, Ho Jae, Soo Hyun Park, and Yun Jung Lee. Signaling cascade of ANG II-induced inhibition of -MG uptake in renal proximal tubule cells. Am J Physiol Renal Physiol 286: F634–F642, 2004. First published November 25, 2003; 10.1152/ajprenal.00217.2003.—ANG II and Na -glucose cotransporter have been reported to be associated with the onset of diverse renal diseases. However, the effect of ANG II ...

Chronic angiotensin (ANG) II infusions into rats lead to augmented intrarenal levels of ANG II and inflammatory factors, impaired renal function, and progressive hypertension. Residual effects persist after cessation of ANG II infusions, as manifested by a hypertensive response to high-salt intake. This study was performed to determine the residual cytokines and chemokines following the cessati...

Angiotensin II (Ang II)-induced arterial baroreflex dysfunction is associated with superoxide generation in the brain. Exercise training (EX) improves baroreflex function and decreases oxidative stress in cardiovascular diseases linked to elevated central Ang II. The aim of this study was to determine whether previous EX prevents baroreflex impairment caused by central administration of exogeno...

Recent studies suggest that atherosclerosis is a kind of inflammatory process and that cytokine plays important roles in this process. Although it is generally accepted that angiotensin II (Ang II) plays an important role in atherogenesis, the role of Ang II in cytokine production has not been explored. In this report, we investigated the effect of Ang II on the production of interleukin-6 (IL-...

Angiotensin II (Ang II) is known to act as a growth factor and may be involved in cardiac remodeling. We have shown that insulin-like growth factor-I (IGF-I) is an autocrine mediator of growth responses to Ang II in vascular smooth muscle cells in vitro, and we hypothesized that IGF-I also serves as an important modulator of cardiovascular growth in vivo. To study the effect of Ang II on cardia...

Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are involved in tissue remodeling processes. TIMP-1 is the main native inhibitor of MMPs and it contributes to the development of tissue fibrosis. It is known that Angiotensin II (Ang II) plays a fundamental role in vascular remodeling. Aim of the study was to investigate whether Ang II modulates TIMP-1 expression in rat aorti...

Angiotensin II (Ang II)–induced arterial baroreflex dysfunction is associated with superoxide generation in the brain. Exercise training (EX) improves baroreflex function and decreases oxidative stress in cardiovascular diseases linked to elevated central Ang II. The aim of this study was to determine whether previous EX prevents baroreflex impairment caused by central administration of exogeno...

Angiotensin II (Ang II)–mediated stimulation of fibroblast growth and collagen type I synthesis is believed to be an important component of the cardiac remodeling process in hypertension and chronic ischemia. Ang II–mediated oxidative stress could be important in enhanced fibroblast growth and collagen formation. Accordingly, we postulated that the PPARligand, pioglitazone, which is known to mo...

We investigated whether upregulation of Src by Ang II leads to increased extracellular signal–regulated kinase 1/2 (ERK1/2) phosphorylation in vascular smooth muscle cells (VSMCs) from spontaneously hypertensive rats (SHR) and whether these processes are associated with altered activation of C-terminal Src kinase (Csk), a negative regulator of Src. Furthermore, the role of epidermal growth fact...

Angiotensin II (Ang II), an effector peptide of the renin-angiotensin system, has been reported to stimulate growth of blood vessels in vivo and smooth muscle cells in culture. In this study, the effect of Ang II on DNA synthesis was examined in deendothelialized human saphenous vein in organ culture. After 7 days' exposure to medium containing 0.4% fetal calf serum plus Ang II, there was a mar...
