Abstract

In this study we investigated the effects of novokinin, an angiotensin type 2 (AT2) receptor agonist, on RAAS components such as renin, angiotensin converting enzyme 1 (ACE1), angiotensin converting enzyme 2 (ACE2), angiotensin type 1 (AT1) receptor,angiotensin type 2 (AT2) receptor, aldosterone which are associated with cardiovascular pathology. We compared the effects of AT1R antagonist losartan, ACE inhibitor perindopril and AT2R agonist novokinin on these parameters. We purposed to clarify how novokinin affects the parcipitant pathways which lead to renal damage, and we also evaluated whether novokinin is effective compared to other RAAS blockers. Materials and Methods: L-NAME was administrated intraperitoneally, salt was given with drinking water (1%) for 4 weeks. Perindopril (2mg/kg/day), losartan (2 mg/kg/day), novokinin (0.1 mg/kg/day), were administrated intraperitoneally for the last 2 weeks. Renin, ACE1, ACE2, AT1R, AT2R, aldosterone were measured by ELISA in the renal tissue. Results: In novokinin, perindopril and losartan-treated group ADE2 and AT2 receptor levels in the renal tissue showed a significant increase while there was a significant decrease in the level of aldosterone. Conclusions: These findings have suggested that novokinin may exert a protective role in the renal injury. Further experimental studies are needed to exhibit potential benefits of AT2 receptor in hypertension and end organ damage

Özet

Bir anjiotensin tip 2 (AT2) reseptör agonisti olan novokinin'in renin, anjiotensin dönüştürücü enzim 1 (ADE1), anjiotensin dönüştürücü enzim 2 (ADE2), anjiotensin tip 1 (AT1) reseptör, anjiotensin tip 2 reseptör ( AT2), aldosteron gibi kardiyovasküler ve renal patolojilerin gelişiminde katılımcı olan renin anjiotensin aldosteron sistemi komponentleri üzerine etkisinin incelenmesi, bu etkilerinin klinikte kullanılan AT1 antagonisti losartan ve ADE inhibitörü perindopril gibi RAAS blokörleri ilaçlar ile karşılaştırıldığında etkili olup olmadığının değerlendirilmesi amaçlandı. Gereç ve Yöntem: 4 hafta boyunca intraperitoneal nitrik oksit sentaz (NOS) inhibitörü, L-NAME ve içme suyuyla %1 tuz verilerek HT oluşturuldu. Perindopril (2 mg/kg/gün), losartan (2 mg/kg/gün), novokinin (0.1 mg/kg/gün) son 2 hafta boyunca intraperitoneal uygulandı. Renin, AT1, AT2, ADE1, ADE2, aldosteron düzeyleri böbrek dokusunda ELİSA ile ölçüldü. Bulgular: Novokinin, perindopril ve losartan tedavisi alan gruplarda ADE2 ve AT2 reseptör seviyesinde böbrek dokusunda anlamlı artış gözlemlenirken aldosteron seviyesinde ise anlamlı azalma görüldü. Sonuç: AT2 reseptör agonist novokinin'in böbrek dokusu da koruyucu etkilerinin olabileceği düşünülebilir. Hipertansiyonun tedavisinde ve hedef organ hasarını önlemede AT2 agonistlerinin potansiyel yararlarını sergileyebilmek için daha fazla çalışmalara ihtiyaç vardır
