Abstract

Local bone marrow renin-angiotensin system (RAS) is an autocrine-paracrine system affecting normal and neoplastic hematopoiesis. Angiotensin converting enzyme (ACE) converts angiotensinogen-I to its physiologically active peptide angiotensin- II, which stimulates proliferation and differentiation of hematopoietic stem cells through angiotensin II type 1 receptors. We investigated the ACE insertion/deletion (I/D) gene polymorphisms in patients with hematological malignancies including acute and chronic leukemia, myelodysplastic syndrome and multiple myeloma. Our results showed that 80.4% of the patients represented ID/II genotype, whereas it was 55.9% of the control group and 3.2 fold increased disease risk in the existence of insertion allele (ID/II). This is the first study demonstrating possible effects of ACE I/D gene polymorphism of the local bone marrow RAS components on leukemic hematopoiesis.

Özet

Lokal kemik iliği renin anjiotensin sistemi (RAS) normal ve neoplastik hematopoezi etkileyen otokrin ve parakrin bir sistemdir. Anjiotensin dönüştürücü enzim (ACE) anjiotensinojen-I’i kendisinin fizyolojik olarak aktif peptide olan anjiotensin II’ye dönüştürür ki, bu hemetopoetik kök hücrelerin çoğalmasını ve farklılaşmasını anjiotensin tip 1 reseptörleri üzerinden uyarır. Biz ACE insersyon/delesyon gen polimorfizmlerini akut ve kronik lösemi, myelodisplastik sendrom ve multiple myeloma gibi hematolojik malignasili hastalarda araştırdık. Çalışma sonuçlarımıza göre hastaların % 80.4’ü ID/II genotipi gösterirken bu oran kontrol grubunda % 55.9 olarak bulundu ve insersiyon alleli varlığında (ID/II) 3.2 kat artmış hastalık riski saptandı. Bu lokal kemik ilği RAS üyelerinden ACE’nin I/D gen polimorfizminin lösemik hematopoezdeki olası etkisini gösteren ilk çalışmadır.
