Comparative effect of direct renin inhibition and AT1R blockade on glomerular filtration barrier injury in the transgenic Ren2 rat.

|
Renin is the rate-limiting step in angiotensin (ANG II) generation.

|
Recent work suggests renin inhibition improves proteinuria comparable to ANG type 1 receptor (AT1R) blockade (ARB).
|

|
Structural and functional alterations were accompanied by increased renal cortical ANG II, AT1R, as well as NADPH oxidase subunit (Nox2) expression compared with SD controls.

|
Whether this protection is due solely to blockade of AT1, or whether diversion of angiotensin II from the AT1 to the available AT2 receptor, thus potentially enhancing AT2 receptor effects, is not known.

Glomerulosclerosis was assessed by renal biopsy 8 wk later, and rats were divided into four groups with equivalent glomerulosclerosis: no further treatment, ARB, AT2 receptor antagonist, or combination.

Kidney cortical collagen content was decreased in ARB, but increased in untreated 5/6 nephrectomy, AT2 receptor antagonist, and combined groups.

|
Plasminogen activator inhibitor-1 mRNA and protein were increased at 12 wk by AT2 receptor antagonist in contrast to decrease with ARB.

AT2 blockade on podocytes and interaction with plasminogen activator inhibitor-1.
|

|
Cultured wild-type podocytes, but not plasminogen activator inhibitor-1 knockout, responded to angiotensin II with increased collagen, an effect that was completely blocked by ARB with lesser effect of AT2 receptor antagonist.
|

|
We conclude that the benefical effects on glomerular injury achieved with ARB are contributed to not only by blockade of the AT1 receptor, but also by increasing angiotensin effects transduced through the AT2 receptor.

Angiotensin II receptor blocker attenuates intrarenal renin-angiotensin-system and podocyte injury in rats with myocardial infarction.
|

|
The present study aimed to test the hypothesis that angiotensin II type 1 receptor blockers (ARBs) provides renoprotective effects after MI by preventing augmented intrarenal renin-angiotensin-system (RAS)-induced podocyte injury.
|
14 |
23799145
|
The current study revealed that MI-induced glomerular podocyte injury was identified by increased immunostaining for desmin and p16(ink4a), decreased immunostaining for Wilms' tumor-1 and podocin mRNA expression, and an induced increase of blood cystatin C at both 3 and 9 weeks.
|
15 |

|
These changes were associated with increased intrarenal angiotensin II levels and enhanced expressions of angiotensinogen mRNA and angiotensin II receptor mRNA and protein.
|
16 |
23799145
|
These changes were also associated with decreased levels of insulin-like growth factor (IGF-1) and decreased expressions of IGF-1 receptor (IGF-1R) protein and mRNA and phosphorylated(p)-Akt protein at 9 weeks, as well as increased expressions of 8-hydroxy-2'-deoxyguanosine at both time points.
|

|
Treatment with losartan significantly attenuated desmin- and p16(ink4a)-positive podocytes, restored podocin mRNA expression, and decreased blood cystatin C levels.
|

|
Losartan also prevented RAS activation and oxidative stress and restored the IGF-1/IGF-1R/Akt pathway.
|
19 |
23799145
|
In conclusion, ARBs prevent the progression of renal impairment after MI via podocyte protection, partially by inhibiting the activation of the local RAS with subsequent enhanced oxidative stress and an inhibited IGF-1/IGF-1R/Akt pathway.

The present study sought to determine whether doses of ARB (AngII receptor blocker) that maximally reduce proteinuria could slow the progression of glomerulosclerosis in the uninephrectomized db/db mouse, a model of Type 2 diabetes.
|
21 |
24195695
|
Untreated uninephrectomized db/db mice had normal blood pressure, but developed progressive albuminuria and mesangial matrix expansion between 18 and 22 weeks of age, which was associated with increased renal expression of TGFβ1 (transforming growth factor β1), PAI-1 (plasminogen-activator inhibitor-1), type IV collagen and FN (fibronectin).
|
22 |
24195695
|
The expression of podocin and nephrin were continually decreased in mice with diabetes between 18 and 22 weeks of age.
|

|
Renal expression of TNFα (tumour necrosis factor α), MCP-1 (monocyte chemoattractant protein-1), Nox2 (NADPH oxidase 2), p22phox and p47phox and urine TBARS (thiobarbituric acid-reacting substance) levels, the markers of renal inflammation and oxidative stress, were increased during disease progression in mice with diabetes.
