Abstract

The aim of this study is to search critical renin-angiotensin system (RAS) elements in myeloid leukemic cell lines. Human acute myeloid leukemia (AML) cell lines, KG-1 and HL-60, were cultured. We searched for the gene expression of the major RAS components in KG-1 and HL-60 cell lines by quantitative real-time polymerase chain reaction analysis (qRT-PCR). Angiotensin-converting enzyme I (ACE I) and ACE II mRNA expressions were detected in KG-1 AML cell line. Relative expression of ACE I was higher than ACE II expression in this myeloid leukemic cells. Likewise, RENIN, angiotensinogen (ANGTS), and ACE I mRNA expressions were detected in HL-60 promyelocytic cell line. Relative RENIN expression was the highest, whereas ACE I expression was the lowest in HL- 60 neoplastic myeloid cells. These findings indicate that there is a biologically active local RAS in the hematopoietic system in normal and pathological states.

Özet

Bu çalışmanın amacı miyeloid lösemik hücre dizilerinde kritik renin-anjiyotensin sistemi (RAS) elemanlarının varlığını araştırmaktır. İnsan akut miyeloid lösemi (AML) hücre dizileri, KG-1 ve HL-60, kültüre edildi. Temel RAS elemanlarının KG-1 ve HL-60 hücre dizilerindeki gen ekspresyon düzeyleri kuantitatif gerçek zamanlı polimeraz zincir reaksiyonu (qRT-PCR) ile araştırıldı. KG-1 AML hücre dizisinde anjiyotensin-dönüştürücü enzim I (ACE I) ve ACE II mRNA ekspresyonları saptandı; ACE I rölatif ekspresyonu, ACE II ekspresyonundan yüksek idi. Benzer şekilde, HL-60 promyelositik hücre dizisinde RENIN, anjiyotensinojen (ANGTS) ve ACE I mRNA ekspresyonları saptandı. HL-60 neoplastik miyeloid hücrelerinde rölatif RENIN ekspresyonu en yüksek iken, ACE I ekspresyonu en düşük düzeyde bulundu. Bu bulgular hematopoetik sistemde normal ve patolojik durumlarda biyolojik aktif lokal bir RAS varlığını göstermektedir.
