Childhood acute lymphoblastic leukemia patients (n=310) were analyzed for four SNPs in the
NR3C1
gene. Polymorphisms -627A/G, intron 2 +646C/G and 9bT/C were all associated with reduced event-free survival. Haplotypes composed of
AGT
alleles at these loci and tagged by the intron 2 +646G variant also associated with lower event-free survival (p=0.03). The progressive impact of this haplotype on outcome was seen with two copies associated with reduced overall survival (p=0.05). Quantitative mRNA analysis in lymphoblastoid cell lines showed that carriers of the
AGT
haplotype had a higher ratio of GR gamma/alpha isoforms (p=0.04), which possibly explains its association with reduced event-free survival and overall survival.

The existence of a local renin-angiotensin system (RAS) specific to the hematopoietic bone marrow (BM) microenvironment had been proposed two decades ago. Most of the RAS molecules including ACE, ACE2,

, NR3C2, PREP, REN, RNPEP, and THOP1 are locally present in the BM microenvironment. Local BM RAS peptides control the hematopoietic niche, myelopoiesis, erythropoiesis, thrombopoiesis and the development of other cellular lineages. Local BM RAS is important in hematopoietic stem cell biology and microenvironment. Angiotensin II regulates the proliferation, differentiation, and engraftment of hematopoietic stem cells. Activation of Mas receptor or ACE2 promotes proliferation of CD34+ cells. BM contains a progenitor that expresses renin throughout development. Angiotensin II attenuates the migration and proliferation of CD34+ Cells and promotes the adhesion of both MNCs and CD34+ cells. Renin cells in hematopoietic organs are precursor B cells. The renin cell requires RBP-J to differentiate. Mutant renin-expressing hematopoietic precursors can cause leukemia. Deletion of RBP-J in the renin-expressing progenitors enriches the precursor B-cell gene programme. Mutant cells undergo a neoplastic transformation, and mice develop a highly penetrant B-cell leukemia with multi-organ infiltration and early death. Many biological conditions during the development and function of blood cells are mediated by RAS, such as apoptosis, cellular proliferation, intracellular signaling, mobilization, angiogenesis, and fibrosis. The aim of this paper is to review recent developments regarding the actions of local BM RAS in the genesis of leukemia and other malignancies molecules.
