Antagonizing Retinoic Acid Receptors Increases Myeloid Cell Production by Cultured Human Hematopoietic Stem Cells

4区 · 医学

Article

作者: Brown, Geoffrey ; Marcinkowska, Ewa ; Marchwicka, Aleksandra ; Cunningham, Alan ; Toellner, Kai-Michael

Activities of the retinoic acid receptor (RAR)α and RARγ are important to hematopoiesis. Here, we have investigated the effects of receptor selective agonists and antagonists on the primitive human hematopoietic cell lines KG1 and NB-4 and purified normal human hematopoietic stem cells (HSCs). Agonizing RARα (by AGN195183) was effective in driving neutrophil differentiation of NB-4 cells and this agonist synergized with a low amount (10 nM) of 1α,25-dihydroxyvitamin D₃ to drive monocyte differentiation of NB-4 and KG1 cells. Treatment of cultures of human HSCs (supplemented with stem cell factor ± interleukin 3) with an antagonist of all RARs (AGN194310) or of RARα (AGN196996) prolonged the lifespan of cultures, up to 55 days, and increased the production of neutrophils and monocytes. Slowing down of cell differentiation was not observed, and instead, hematopoietic stem and progenitor cells had expanded in number. Antagonism of RARγ (by AGN205728) did not affect cultures of HSCs. Studies of CV-1 and LNCaP cells transfected with RAR expression vectors and a reporter vector revealed that RARγ and RARβ are activated by sub-nM all-trans retinoic acid (EC₅₀-0.3 nM): ~50-fold more is required for activation of RARα (EC₅₀-16 nM). These findings further support the notion that the balance of expression and activity of RARα and RARγ are important to hematopoietic stem and progenitor cell expansion and differentiation.

ATRA and the specific RARα agonist, NRX195183, have opposing effects on the clonogenicity of pre-leukemic murine AML1-ETO bone marrow cells

1区 · 医学

Article

All-trans retinoic acid (ATRA) is used successfully in the treatment of acute promyelocytic leukemia (APL). ATRA enhances hematopoietic stem cell self-renewal through retinoic acid receptor (RAR)γ activation while promoting differentiation of committed myeloid progenitors through RARα activation. Its lack of success in the treatment of non-APL acute myeloid leukemia (AML) may be related to ATRA's non-selectivity for the RARα and RARγ isotypes, and specific RARα activation may be more beneficial in promoting myeloid differentiation. To investigate this hypothesis, the effects of ATRA and the specific RARα agonist NRX195183 was assessed in AML1-ETO (AE)-expressing murine bone marrow (BM) progenitors. ATRA potentiated the in vitro clonogenicity of these cells while NRX195183 had the opposite effect. Morphological and flow cytometric analysis confirmed a predominantly immature myeloid population in the ATRA-treated AE cells while the NRX195183-treated cells demonstrated an increase in the mature myeloid population. Similarly, NRX195183 treatment promoted myeloid differentiation in an AE9a in vivo murine model. In the ATRA-treated AE cells, gene expression analyses revealed functional networks involving SERPINE1 and bone morphogenetic protein 2; AKT phosphorylation was upregulated. Collectively, these findings confirm the contrasting roles of specific RARα and RARγ activation in the clonogenicity and differentiation of AE cells with potential significant implications in the treatment of non-APL AML using a specific RARα agonist.

Inhibition of ectopic bone formation by a selective retinoic acid receptor α‐agonist: A new therapy for heterotopic ossification?

AbstractHeterotopic ossification (HO) consists of formation of ectopic cartilage followed by endochondral bone and is triggered by major surgeries, large wounds, and other conditions. Current therapies, including low‐dose irradiation, are not always effective and do not target the skeletogenic process directly. Because chondrogenesis requires a decrease of nuclear retinoic acid receptor α (RARα) action, we reasoned that pharmacologic activation of this receptor pathway should inhibit HO. Thus, we selected the synthetic retinoid NRX195183, a potent and highly selective RARα‐agonist, and found that it did inhibit chondrogenesis in mouse limb micromass cultures. We established a mouse HO model consisting of subcutaneous implantation of Matrigel mixed with rhBMP‐2. Control mice receiving daily oral doses of vehicle (peanut oil) or retinol (a natural nonactive retinoid precursor) developed large HO‐like masses by days 9–12 that displayed abundant cartilage, endochondral bone, vessels, and marrow. In contrast, formation of HO‐like masses was markedly reduced in companion mice receiving daily oral doses of α‐agonist. These ectopic masses contained sharply reduced amounts of cartilage and bone, blood vessels, and TRAP‐positive osteoclasts, and expressed markedly lower levels of master chondrogenic genes including Sox9, cartilage genes such as collagen XI and X, and osteogenic genes including Runx2. The data provide proof‐of‐principle evidence that a pharmacological strategy involving a selective RARα‐agonist can indeed counteract an ectopic skeletal‐formation process effectively and efficiently, and could thus represent a novel preventive treatment for HO. © 2009 Orthopaedic Research Society.
