Abstract
PURPOSE Clodronate-liposomes (Clod-Lip) is an effective candidate drug for treating chronic myelomonocytic leukemia, autoimmune hemolytic anemia and immune thrombocytopenic purpura in mice experiments. But its role in hematopoietic recovery after acute myelosuppression is still unknown. We aim to explore the function and underlining mechanisms of Clod-Lip on hematopoietic reconstitution after sublethal dose irradiation in mice. MATERIALS AND METHODS Mice at 8-10 weeks received a total-body sublethal dose γ-irradiation (TBI) and injected with Clod-Lip or PBS-Liposomes (PBS-Lip) every 4 days after TBI. The survival rate of each group was recorded. Flow cytometry was used to analyze changes in hematopoietic stem cells and their progenies in bone marrow. ELISA and RT-qPCR were used for the analysis of hematopoietic regulatory factors. Regarding IL-1β inhibition, 25 mg/kg diacerein or an equal volume of DMSO was intraperitoneally injected into mice every day after TBI. RESULTS In sublethal dose-irradiated mice, Clod-Lip reduced the survival rate, the total number of bone marrow and hematopoietic stem cells, delayed peripheral blood recovery of red blood cells and platelets. However, it could increase the number of CMP, MEP and myeloid cells, which suggested that Clod-Lip could induce HSC to myeloid differentiation in vivo. We further verified that Clod-Lip may induce myeloid differentiation by bone marrow microenvironmental factor IL-1β. CONCLUSIONS In summary, this study suggested that Clod-Lip may aggravate inhibitor effect of hematopoietic function and promote myeloid differentiation in myelosuppression mice model.

Int J Radiat Oncol Biol Phys 2018; 103:945-957. [PMID: 30458235 DOI: 10.1016/j.ijrobp.2018.11.021] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2018] [Revised: 10/26/2018] [Accepted: 11/10/2018] [Indexed: 12/25/2022]
Abstract
PURPOSE To evaluate the protective effect of inorganic nitrate against systemic damage in a mouse model of total body gamma irradiation (TBI). METHODS AND MATERIALS C57BL/6 mice in the irradiation (IR) + NaNO3 group were pretreated with 2 mmol/L NaNO3 in their drinking water for 1 week before receiving 5 Gy irradiation. Animals that received only 5 Gy irradiation were designated as the IR group. Survival and body weight were monitored. The peripheral blood lymphocytes, heart, liver, lung, and submandibular gland were harvested and assessed. Reactive oxygen species (ROS) were measured in the lung and submandibular gland. We examined phosphorylated histone H2AX (p-H2AX) and p53-binding protein 1 (53BP1) as markers of early-stage DNA damage and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and Bax/caspase 3 mRNA expression as markers of apoptosis. RESULTS No improvement of survival was observed in the IR + NaNO3 group after TBI, but body weight loss after 5 Gy TBI was significantly attenuated in the IR + NaNO3 group. The levels of peripheral blood erythrocytes, leukocytes, and platelets at 7 days postirradiation recovered with nitrate treatment; moreover, the p-H2AX level in the peripheral blood lymphocytes was much lower in the IR + NaNO3 group at 2 and 4 hours post irradiation. In the lung and submandibular gland, the levels of p-H2AX, 53BP1 and ROS as well as TUNEL staining were significantly decreased in the IR + NaNO3 group compared with those in the IR group. Gene expression of Bax and caspase 3 was decreased in both the lung and submandibular gland with nitrate treatment, indicating attenuation of apoptosis. CONCLUSION Inorganic nitrate delivery could effectively prevent TBI-induced systemic damage. Nitrate-mediated decreases in ROS levels may contribute to this systemic protective effect.

Abstract
Trace elements play crucial role in the maintenance of genome stability in the cells. Many endogenous defense enzymes are containing trace elements such as superoxide dismutase and metalloproteins. These enzymes are contributing in the detoxification of reactive oxidative species (ROS) induced by ionizing radiation in the cells. Zinc, copper, manganese, and selenium are main trace elements that have protective roles against radiation-induced DNA damages. Trace elements in the free salt forms have protective effect against cell toxicity induced by oxidative stress, metal-complex are more active in the attenuation of ROS particularly through superoxide dismutase mimetic activity. Manganese-complexes in protection of normal cell against radiation without any protective effect on cancer cells are more interesting compounds in this topic. The aim of this paper to review the role of trace elements in protection cells against genotoxicity and side effects induced by ionizing radiation.
