Renin-Angiotensin System Suppression Mitigates Experimental Radiation Pneumonitis

Renin-angiotensin system and unilateral ureteral obstruction

Unilateral ureteral obstruction (UUO) is a clinical scenario that leads to obstructive nephropathy. UUO alters the expression of many mediators in the ipsilateral kidney. Renin-angiotensin system (RAS) is involved in UUO. Angiotensin II (Ang II) and angiotensin 1-7 (Ang 1-7) as the main arms of RAS influence kidney function which may alter by UUO. Ang II via Ang II receptor subtypes I (AT1R) ...

Curcumin Mitigates Radiation-induced Lung Pneumonitis and Fibrosis in Rats

Radiation-induced lung injury is one of the most prominent factors that interfere with chest cancer radiotherapy, and poses a great threat to patients exposed to total body irradiation. Upregulation of pro-oxidant enzymes is one of the main mechanisms through which the late effects of ionizing radiation on lung injury can be exerted. Interleukin (IL)-4 and IL-13 are two important cytokines that...

Renin - Angiotensin - Aldosterone System

Chronic heart failure (CHF) is associated with endothelial dysfunction. Activation of the renin-angiotensin-aldosterone system (RAAS) is believed to be important in the deterioration of endothelial dysfunction in CHF through stimulation of oxidative stress. Whereas angiotensin-converting enzyme inhibitors (ACE-I) improve endothelial function in CHF, the effects of angiotensin II AT 1-receptor b...
